All computers produce heat when they work, and Macs are no exception. The processor (CPU) and graphics processor (GPU) naturally generate heat when they're being used. The cooling system, consisting of one or more fans and heat pipes, is designed to remove this heat.<\/p>\n\n<p>The problem starts when the heat exceeds what the system can remove. The fans then run at full speed to compensate, creating that characteristic wind tunnel noise that is so worrying. In severe cases, the Mac deliberately slows down its performance (this is called the <em>thermal throttling<\/em>) to avoid damaging the components.<\/p>\n\n<p>In 15 years of repair work in Brussels, we have found that overheating is one of the five most common reasons for consultation. The good news is that in the vast majority of cases, the problem can be resolved without replacing any parts.<\/p>\n\n<h2 id=\"causes-frequentes\">Common causes of Mac overheating<\/h2>\n\n<p>Before moving on to solutions, it's important to understand what causes overheating. Here are the most common causes we diagnose in the workshop:<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Cause<\/th>\n<th>Frequency<\/th>\n<th>Gravity<\/th>\n<th>Solution<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">Accumulated dust<\/span><\/td>\n<td>Very frequent<\/td>\n<td>Average<\/td>\n<td>Internal cleaning<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Background-intensive applications<\/span><\/td>\n<td>Very frequent<\/td>\n<td>Low<\/td>\n<td>Activity monitor<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Used thermal paste<\/span><\/td>\n<td>Frequent (Mac 3 years and over)<\/td>\n<td>Average<\/td>\n<td>Paste replacement<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Too many browser tabs<\/span><\/td>\n<td>Frequent<\/td>\n<td>Low<\/td>\n<td>Close unnecessary tabs<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">macOS or obsolete apps<\/span><\/td>\n<td>Moderate<\/td>\n<td>Low<\/td>\n<td>Updates<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Faulty fan<\/span><\/td>\n<td>Rare<\/td>\n<td>High<\/td>\n<td>Fan replacement<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Surface blocking ventilation<\/span><\/td>\n<td>Frequent<\/td>\n<td>Low<\/td>\n<td>Change surface<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Thermal sensor faulty<\/span><\/td>\n<td>Rare<\/td>\n<td>High<\/td>\n<td>Workshop diagnosis<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<div class=\"info-box tip\">\n<strong>Good to know:<\/strong> Apple Silicon Macs (M1, M2, M3, M4) generally run cooler than older Intel models. If your Apple Silicon MacBook heats up excessively, the cause is often poorly optimised software.\n<\/div>\n\n<h2 id=\"verifier-moniteur-activite\">Solution 1: check the Activity Monitor<\/h2>\n\n<p>The first thing to do when faced with an overheating Mac is to identify what's consuming resources. The Activity Monitor is the tool built into macOS that shows you exactly which processes are using up your processor.<\/p>\n\n<h3>How to open the Activity Monitor<\/h3>\n\n<p>Open the Finder, go to Applications, then Utilities, and launch Activity Monitor. You can also find it quickly with Spotlight: press <strong>Cmd + Space<\/strong> and type \u00abActivity Monitor\u00bb.<\/p>\n\n<p>Once open, click on the <strong>CPU<\/strong> at the top of the window and sort by <strong>% CPU<\/strong> by clicking on the column header. The most power-hungry processes appear at the top.<\/p>\n\n<h3>How to interpret the results<\/h3>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>CPU usage<\/th>\n<th>Situation<\/th>\n<th>Action<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">0 to 30 %<\/span><\/td>\n<td>Normal, light use<\/td>\n<td>No action required<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">30 to 70 %<\/span><\/td>\n<td>Moderate load, fans possible<\/td>\n<td>Monitoring dominant processes<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">70 to 100 %<\/span><\/td>\n<td>High load, fans likely<\/td>\n<td>Identify and close unnecessary processes<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">A continuous 100 % process<\/span><\/td>\n<td>Blocked process or malware<\/td>\n<td>Force exit or launch an antivirus scan<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<p>If a process you don't recognise is consuming more than 80 % of CPU continuously, it may be malware. In this case, consult our <a href=\"https:\/\/reparationmac.be\/en\/is-antivirus-necessary-on-mac-tests\/\">Mac antivirus security guide<\/a> to scan.<\/p>\n\n<h2 id=\"fermer-applications\">Solution 2: Close power-hungry applications<\/h2>\n\n<p>Some applications are notorious for making heavy demands on the processor, especially on older Macs. The usual culprits are video editing software (Final Cut Pro, Premiere Pro), photo editing software (Photoshop, Lightroom), video conferencing applications (Zoom, Teams, Google Meet) and certain games.<\/p>\n\n<p>To force the closure of an application that is blocked or too greedy:<\/p>\n\n<p>Press the <strong>Cmd + Option + Escape<\/strong> to open the \u00abForce Quit\u00bb window. Select the problematic application and click on \u00abForce Quit\u00bb. You can also right-click on the application icon in the Dock and choose \u00abForce Quit\u00bb.<\/p>\n\n<div class=\"info-box warning\">\n<strong>Please note:<\/strong> Forcing an application to close will cause any unsaved data to be lost. Remember to save your work regularly with <strong>Cmd + S<\/strong>.\n<\/div>\n\n<p>If your Mac is generally slow and heats up even with few applications open, the problem may lie deeper. Our <a href=\"https:\/\/reparationmac.be\/en\/slow-mac-solutions-optimization\/\">guide to solving a slow Mac<\/a> details 12 additional optimisation solutions.<\/p>\n\n<h2 id=\"navigateur-onglets\">Solution 3: Reduce browser tabs<\/h2>\n\n<p>This is a cause of overheating that many people underestimate. Each tab opened in Chrome, Safari or Firefox consumes memory and CPU, especially if the pages contain videos, animations or interactive ads. Having 30 tabs open simultaneously can easily consume 40 to 60 % of CPU resources.<\/p>\n\n<p>Chrome is particularly greedy because each tab runs as a separate process. Safari, which is optimised for macOS, manages resources better but is not immune to large numbers of tabs.<\/p>\n\n<p>A few simple habits will considerably reduce the heat load: close tabs that you are not actively viewing, use extensions such as \u00abThe Great Suspender\u00bb (Chrome) or \u00abTab Suspender\u00bb (Firefox) that put inactive tabs to sleep, and avoid running videos in the background.<\/p>\n\n<h2 id=\"mise-a-jour-macos\">Solution 4: Update macOS and applications<\/h2>\n\n<p>Updates to macOS don't just add new features. They also fix bugs that can cause excessive CPU usage. A poorly optimised system process in an earlier version can loop and generate heat unnecessarily.<\/p>\n\n<p>To check for updates, open <strong>System settings<\/strong> (or System Preferences on older versions), then click on <strong>General<\/strong> and <strong>Software updates<\/strong>. Install any available updates.<\/p>\n\n<p>Also remember to update applications via the App Store (Updates tab) and directly in third-party applications. An out-of-date version of Spotify, Slack or Discord may contain a bug causing abnormal CPU consumption.<\/p>\n\n<div class=\"info-box tip\">\n<strong>Tip:<\/strong> After a major update to macOS, it's normal for the Mac to heat up for a few hours. The system re-indexes Spotlight and optimises files in the background. Leave it plugged in and wait for the process to finish.\n<\/div>\n\n<h2 id=\"reinitialiser-smc\">Solution 5: reset the SMC (Intel Mac only)<\/h2>\n\n<p>The SMC (System Management Controller) is the chip that manages your Mac's fans, battery, lights and thermal management. When the SMC malfunctions, the fans may spin at full speed for no apparent reason, or fail to kick in when they should.<\/p>\n\n<h3>Resetting the SMC on a MacBook with a T2 chip (2018-2020)<\/h3>\n\n<p>Switch off your MacBook. Hold down the <strong>Ctrl + Option + Shift<\/strong> (left side) for 7 seconds, then add the power button and hold the four buttons together for a further 7 seconds. Release everything, wait a few seconds, then switch on again as normal.<\/p>\n\n<h3>Resetting the SMC on a MacBook without a T2 chip (before 2018)<\/h3>\n\n<p>Switch off your MacBook. Hold <strong>Shift + Ctrl + Option<\/strong> (left side) and the power button for 10 seconds. Release everything, then switch it back on.<\/p>\n\n<h3>Intel desktop Mac (iMac, Mac mini, Mac Pro)<\/h3>\n\n<p>Turn off the Mac, unplug the power cable, wait 15 seconds, plug it back in and wait 5 seconds before turning it back on.<\/p>\n\n<div class=\"info-box warning\">\n<strong>Mac Apple Silicon (M1\/M2\/M3\/M4) :<\/strong> There is no SMC to reset on these models. A simple reboot is all it takes to reset the thermal management. If you don't know which processor is powering your Mac, use our <a href=\"https:\/\/reparationmac.be\/en\/identify-your-mac\/\">Mac identification tool<\/a>.\n<\/div>\n\n<p>For a complete guide to resetting your Mac, see our <a href=\"https:\/\/reparationmac.be\/en\/reset-mac-to-factory-settings\/\">Mac reset tutorial<\/a>.<\/p>\n\n<h2 id=\"nettoyer-aerations\">Solution 6: Clean the external vents<\/h2>\n\n<p>The air vents on your Mac are where the hot air exits. On a MacBook, they are located along the hinge, between the screen and the keyboard. On an iMac, they're located under the screen and at the back. On a Mac mini, they are at the bottom of the case.<\/p>\n\n<p>Over time, dust, pet hair and fibres accumulate on these grilles and reduce airflow. Sometimes an external cleaning is all it takes to see a noticeable improvement:<\/p>\n\n<p>Switch off your Mac and unplug it. Use a compressed air canister (available from electronics shops), keeping the nozzle 10-15 cm from the grilles. Blow in short bursts while tilting the Mac to help the dust out. Avoid tilting the compressed air can, as the liquid propellant could damage the components.<\/p>\n\n<div class=\"info-box danger\">\n<strong>Important information:<\/strong> Never use a hoover directly on the ventilation grilles. Vacuuming can damage the fan blades or generate static electricity. Always use a compressed air spray can or a soft brush.\n<\/div>\n\n<h2 id=\"environnement-ventilation\">Solution 7: Improve ventilation around the Mac<\/h2>\n\n<p>The environment in which you use your Mac plays a major role in its temperature. A MacBook placed on a bed, sofa or lap will have its air vents partially or totally blocked by the fabric.<\/p>\n\n<p>Here are some best practices:<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Practice<\/th>\n<th>Thermal impact<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">Use a raised stand<\/span><\/td>\n<td><span class=\"cell-desc\">Reduces the temperature by 5 to 10\u00b0C by improving air circulation under the MacBook<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Working on a flat, hard surface<\/span><\/td>\n<td><span class=\"cell-desc\">Allows vents to function normally<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Avoid direct sunlight<\/span><\/td>\n<td><span class=\"cell-desc\">Aluminium casing absorbs heat quickly<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Cooling pad with integrated fans<\/span><\/td>\n<td><span class=\"cell-desc\">Modest reduction of 3 to 5\u00b0C, useful for older Macs<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Remove the protective cover or shell during intensive use<\/span><\/td>\n<td><span class=\"cell-desc\">Shells insulate the case and retain heat<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<h2 id=\"pate-thermique\">Solution 8: Replace the thermal paste<\/h2>\n\n<p>Thermal paste is the conductive material applied between the processor and the heat sink. Its role is to fill in surface micro-imperfections to optimise heat transfer. Over time - generally after 3 to 5 years - this paste dries, hardens and loses its effectiveness.<\/p>\n\n<p>Replacing the thermal paste is one of the most effective ways of combating chronic overheating. On Intel Macs from 2015 to 2020 that we treat in our workshops, the benefits are often spectacular: a reduction of 10 to 20\u00b0C in the temperature of the processor and fans that become silent again in normal use.<\/p>\n\n<p>This operation involves dismantling the Mac, removing the heatsink, cleaning the old paste with isopropyl alcohol and applying a quality paste (Arctic MX-6, Thermal Grizzly Kryonaut or equivalent). This is a delicate operation that requires experience: too much paste or uneven application can aggravate the problem.<\/p>\n\n<p>At R\u00e9paration MAC, thermal paste replacement is included in our service. <a href=\"https:\/\/reparationmac.be\/en\/preventive-mac-maintenance\/\">preventive maintenance service<\/a>, with full cleaning and thermal diagnosis.<\/p>\n\n<h2 id=\"nettoyage-interne\">Solution 9: Professional internal cleaning<\/h2>\n\n<p>When the compressed-air canister no longer suffices, it's because dust has accumulated inside: on the fan blades, around the heat sink, in the nooks and crannies of the case. A MacBook used for 2-3 years in an environment with pets or a lot of dust can have its airflow reduced by 50 % or more.<\/p>\n\n<p>Internal cleaning involves partially dismantling the Mac: removing the bottom cover on a MacBook, meticulously cleaning the fans and heatsinks with professional compressed air, an antistatic brush and isopropyl alcohol. This is also an opportunity to check the condition of the fan itself (bearings, cable, connector) and the thermal paste.<\/p>\n\n<img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/03\/nettoyage-interne-ventilateur-macbook.webp\" alt=\"Internal cleaning of Mac overheating fan\" title=\"Internal cleaning of MacBook fans and heatsink\" width=\"1200\" height=\"568\" loading=\"lazy\">\n\n<div class=\"info-box tip\">\n<strong>Our advice:<\/strong> If your Mac is more than 3 years old and you've never cleaned it internally, there's a good chance that accumulated dust is contributing significantly to overheating. An internal cleaning with thermal paste replacement usually restores the cooling system to its original efficiency.\n<\/div>\n\n<h2 id=\"quand-sinquieter\">When should you really worry?<\/h2>\n\n<p>A lukewarm Mac during intensive use is perfectly normal. But there are certain signs that should alert you and warrant a professional diagnosis:<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Symptom<\/th>\n<th>Probable cause<\/th>\n<th>Emergency<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">Fans at full speed all the time, even when at rest<\/span><\/td>\n<td>Thermal sensor faulty or SMC blocked<\/td>\n<td>Average<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Sudden switch-off without warning<\/span><\/td>\n<td>Critical overheating, thermal safety activated<\/td>\n<td>High<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Smell of burning or hot plastic<\/span><\/td>\n<td>Damaged component, potential short-circuit<\/td>\n<td>Urgent<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Keyboard keys are hot to the touch<\/span><\/td>\n<td>Dried thermal paste or fan out of order<\/td>\n<td>High<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">No fan noise despite the heat<\/span><\/td>\n<td>Fan faulty or cable disconnected<\/td>\n<td>High<\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Severe slowing and jerking<\/span><\/td>\n<td>Thermal throttling, the Mac reduces its performance<\/td>\n<td>Average<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<p>If you smell something burning, turn off your Mac immediately and unplug it. Do not turn it back on until you have obtained a <a href=\"https:\/\/reparationmac.be\/en\/free-mac-diagnostic\/\">professional diagnosis<\/a>. This type of symptom may indicate a motherboard or battery problem that requires urgent attention.<\/p>\n\n<img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/03\/diagnostic-thermique-macbook-atelier.webp\" alt=\"Mac overheating diagnostics in Brussels workshop\" title=\"Thermal diagnosis of a MacBook in the workshop at R\u00e9paration MAC in Brussels\" width=\"1200\" height=\"568\" loading=\"lazy\">\n\n<h2 id=\"faq\">Frequently asked questions<\/h2>\n\n<div class=\"faq-section\">\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Is it normal for my MacBook to overheat?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Yes, a MacBook that feels warm in use is perfectly normal. The processor generates heat and the aluminium casing acts as a heatsink. It's when the Mac becomes hot to the touch or the fans are constantly running that the situation warrants attention.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My Mac heats up but the fans don't turn, is this serious?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>If your Mac heats up but the fans don't turn on, this could indicate a faulty fan or a problem with the thermal sensor. On Apple Silicon Macs, the fans can remain silent under light load because the chips are very efficient. But if the Mac is burning up without ventilation, get it diagnosed.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>How do I check my Mac's temperature?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>macOS does not display the temperature natively. You can use free applications such as <strong>Hot<\/strong> (in the menu bar) or <strong>Stats<\/strong> (open source). In the workshop, we use professional probes to accurately measure the temperatures of internal components.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Do Apple Silicon Macs (M1, M2, M3, M4) also overheat?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Much less than Intel models. Apple Silicon chips are designed to be energy-efficient and produce much less heat. The MacBook Air M1\/M2 doesn't even have a fan. Overheating on Apple Silicon is generally caused by poorly optimised software (like some Intel apps running on Rosetta 2).<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>How much does an internal Mac cleaning cost?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>At R\u00e9paration MAC, an internal cleaning with thermal paste replacement is part of our preventive maintenance service. Prices depend on the exact model. You can consult our <a href=\"https:\/\/reparationmac.be\/en\/mac-pricing\/\">detailed rates<\/a> or request a free quote online.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Is a cooling pad really useful for MacBooks?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>A cooling pad offers a modest reduction of 3 to 5\u00b0C, which can help on an older Mac that heats up a lot. However, it's no substitute for internal cleaning or thermal paste replacement. A simple raised stand that improves air circulation under the MacBook is often just as effective and takes up less space.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Can overheating permanently damage my Mac?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Macs have thermal protections that shut down the computer before irreversible damage occurs. However, chronic overheating accelerates the ageing of the battery, can degrade the thermal paste more quickly and, in extreme cases, can cause micro-welds to fail on the motherboard.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My iMac heats up a lot, is it the same causes?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Yes, the causes are similar: dust, worn thermal paste and greedy software processes. iMacs have the advantage of more internal space for ventilation, but their slim design still collects dust. Cleaning an iMac requires specialist tools because the screen is glued.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Can I clean the inside of my MacBook myself?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Technically, this is possible on MacBooks with accessible Pentalobe screws. However, there are risks: damaging a connector, dislodging a ribbon cable or creating static electricity. If your Mac is still under Apple warranty, opening it by a third party may invalidate it. For a complete cleaning using thermal paste, we recommend a visit to our workshop.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My Mac is getting hotter since the last macOS update. What can I do?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>After an update, macOS performs optimisation tasks in the background (Spotlight indexing, APFS compilation) which can last from a few hours to a day. Leave your Mac plugged in and in standby mode overnight. If the overheating persists after 48 hours, check the Activity Monitor to identify an abnormal process.<\/p><\/div>\n<\/div>\n\n<\/div>\n\n<div class=\"related-links\">\n<strong>Related articles<\/strong>\n<ul>\n<li><a href=\"https:\/\/reparationmac.be\/en\/mac-wont-turn-on\/\">Mac won't turn on: 7 troubleshooting solutions<\/a><\/li>\n<li><a href=\"https:\/\/reparationmac.be\/en\/slow-mac-solutions-optimization\/\">Slow Macs: 12 solutions to restore performance<\/a><\/li>\n<li><a href=\"https:\/\/reparationmac.be\/en\/macbook-black-screen-solutions\/\">MacBook black screen: 8 repair methods<\/a><\/li>\n<li><a href=\"https:\/\/reparationmac.be\/en\/clean-up-mac-free-up-space\/\">Cleaning your Mac: a complete guide to freeing up space<\/a><\/li>\n<\/ul>\n<\/div>\n\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Mac qui chauffe et ventilateur bruyant : 9 solutions efficaces Lecture : 11 min | Pannes et Solutions En r\u00e9sum\u00e9 : Un Mac qui surchauffe avec des ventilateurs en plein r\u00e9gime est souvent caus\u00e9 par une accumulation de poussi\u00e8re, des applications trop gourmandes ou une p\u00e2te thermique us\u00e9e.
