To get this done as effectively and smoothly as possible, there are some things that you'll want to make sure you have at the ready. These are:<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"500\" height=\"350\" src=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Thermal-Paste-Is-Applied-to-the-Laptop-Processor.jpg\" alt=\"Thermal Paste Is Applied to the Processor\" class=\"wp-image-2508\" srcset=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Thermal-Paste-Is-Applied-to-the-Laptop-Processor.jpg 500w, https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Thermal-Paste-Is-Applied-to-the-Laptop-Processor-300x210.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure><\/div>\n\n\n\n<ul><li>Isopropyl alcohol solution (99% is optimal, but anything above 90% will work) or thermal paste cleaner. You can also use nail polish remover but aim for the kinds which are pure acetone. Also keep it away from plastics, as acetone can damage them.<\/li><li>A microfiber cloth<\/li><li>Paper towels<\/li><li>Cotton swabs (optional)<\/li><\/ul>\n\n\n\n<p>Once you've got these by your side, you can get to cleaning thermal paste from your processor.<\/p>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"Remove_the_CPU_Cooler\"><\/span>Remove the CPU Cooler<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The first thing to do before you can clean thermal paste is to remove the CPU cooler that sits on top of the processor. This is how you get access to where the thermal paste is located.<\/p>\n\n\n\n<p>Before you remove your cooler, make sure that your PC is switched off and unplugged from power. Also, unplug the little wire that gives the CPU fan power.<\/p>\n\n\n\n<p>How you'll get your cooler off depends on the exact model that you use. Some use screws, while others might resort to clips.<\/p>\n\n\n\n<p>The best way to know how to remove your heatsink is by checking the product manual or searching online.<\/p>\n\n\n\n<p>Once you've freed the restraints for the cooler, gently twist it left and right to free it of any thermal paste that has dried and stuck it to the processor. Once it starts moving freely, pull it upwards and put it aside.<\/p>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"Clean_the_CPU_Thermal_Paste\"><\/span>Clean the CPU Thermal Paste<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Now, it's time to actually remove the thermal paste from your CPU.<\/p>\n\n\n\n<p>Note that you don't need to remove the processor from the CPU socket! You can clean it just fine with it installed, and removing it increases the risk of damage to the CPU pins.<\/p>\n\n\n\n<ol><li>The first thing you want to do is use a paper towel to gently wipe away as much thermal paste as possible. Don't worry about getting every last bit if it doesn't come off easily.<\/li><li>To take off what remains, get your microfiber cloth and apply a small amount of isopropyl alcohol to it. You can also use a TIM (thermal interface material) cleaner if you opted for that instead, and follow its instructions.<\/li><li>Now, with the damp cloth, wipe the CPU gently until there's no more thermal paste left on the processor.<\/li><li>The edges of the chip can be hard to get to. You can apply alcohol to the tip of a cotton swab and use it to gently dissolve any thermal compound remaining.<\/li><\/ol>\n\n\n\n<p>Now that you've cleaned your CPU, you might be very excited to get it running again, but you need to be patient. You will have to let the CPU dry completely before proceeding. I recommend waiting about an hour if you use 99% isopropyl alcohol. The lower the number, the longer it will take to dry.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"500\" height=\"350\" src=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Motherboard-with-CPU-Socket-Heatsink-and-Other-Components.jpg\" alt=\"Motherboard with CPU Socket Heatsink and Other Components\" class=\"wp-image-2510\" srcset=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Motherboard-with-CPU-Socket-Heatsink-and-Other-Components.jpg 500w, https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Motherboard-with-CPU-Socket-Heatsink-and-Other-Components-300x210.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure><\/div>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"Clean_the_CPU_Cooler\"><\/span>Clean the CPU Cooler<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>While waiting for the CPU to dry, you can also clean the excess thermal paste from the CPU cooler.<\/p>\n\n\n\n<p>While you have to avoid putting too much pressure on the processor when cleaning its thermal paste, you can be a bit more carefree when dealing with the heatsink.<\/p>\n\n\n\n<p>Use a paper towel to remove most of the paste before using a microfiber cloth with a bit of rubbing alcohol on it to finish the job.<\/p>\n\n\n\n<p>If the paste is very dry, you can use a plastic spudger to scrape it off the underside of the heatsink.<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"How_Do_You_Apply_New_Thermal_Paste_to_a_CPU\"><\/span>How Do You Apply New Thermal Paste to a CPU?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>It is important to know exactly how to reapply thermal paste because this is one part of building a computer that a lot of people get very wrong.<\/p>\n\n\n\n<p>There are many manufacturers in the market offering different thermal pastes, which have different performances.<\/p>\n\n\n\n<p>For instance, you have standard and liquid metal thermal pastes. The latter performs extremely well for heat transfer, but they tend to be electrically conductive, which means you have to be extremely precise during application.<\/p>\n\n\n\n<p>For this reason, I always recommend that the average person sticks to applying standard thermal paste. I recommend <a class=\"aawp-link\" href=\"https:\/\/www.amazon.com\/dp\/B086WZ8HBR?tag=cpu4-20&amp;linkCode=ogi&amp;th=1&amp;psc=1\" title=\"Cooler Master MasterGel Pro V2\" target=\"_blank\" rel=\"nofollow noopener\" data-aawp-product-id=\"B086WZ8HBR\" data-aawp-product-title=\"Cooler Master MasterGel Pro V2 High Thermal Conductivity Compound for CPU Coolers  9 W\/mK  \u2013 Ultra-Efficient CPU\/GPU Heat Dissipation with Zero Electrical Conductivity Applicator Included\" data-aawp-geotargeting=\"true\">Cooler Master MasterGel Pro V2<\/a>.<\/p>\n\n\n\n<p>Let's get to actually applying thermal paste. It will usually come in a syringe. Many people mess up when it comes to how much thermal paste to put onto the CPU. Apply a pea-sized bit of thermal paste onto the CPU, in the center. You don't need to spread it out.<\/p>\n\n\n\n<p>Place the bottom of your heatsink onto the CPU, and apply continuous light pressure as you mount it in place. The thermal paste will be evenly spread out as you do this. With too much paste, it can spill over, and you don't want it to get to the CPU pins.<\/p>\n\n\n\n<p>If you're using a new cooler with pre-applied paste, there's no need to do any of this. If you're using the same cooler as before though, you can go ahead!<\/p>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Should_I_Clean_Thermal_Paste_off_My_CPU\"><\/span>Should I Clean Thermal Paste off My CPU?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Thermal paste is a special compound that is applied to the top of your <a href=\"https:\/\/cpuforever.com\/processor\/\" target=\"_blank\" rel=\"noreferrer noopener\">processor<\/a> to fill the gap between it and the CPU cooler.<\/p>\n\n\n\n<p>It is manufactured with thermal conductivity in mind, so it does well in transferring the heat from the CPU to the heatsink, where the fan or water cooling can carry it away.<\/p>\n\n\n\n<p>When your thermal paste gets old, it starts to dry up and this affects how well it can transfer heat to the cooler. When this happens, your CPU may begin to overheat, which can slow down your computer and even cause sudden shutdowns.<\/p>\n\n\n\n<p>You should definitely remove thermal paste from your CPU when it has been on long enough, or when you suspect it's the cause of your overheating PC.<\/p>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"How_Often_Should_I_Remove_Thermal_Paste_from_My_CPU\"><\/span>How Often Should I Remove Thermal Paste from My CPU?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>How often you remove thermal paste depends on several factors.<\/p>\n\n\n\n<p>For instance, which brand of thermal paste are you using? What is the peak temperature of your CPU, and how long is it sustained at high temps? All these questions can change how long your thermal paste lasts.<\/p>\n\n\n\n<p>However, as a general rule, I recommend replacing your thermal paste every two years. However, you will usually be able to get away with replacing it every three years, though I prefer not to give it the chance to dry up.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img decoding=\"async\" loading=\"lazy\" width=\"500\" height=\"350\" src=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Replacing-thermal-paste-on-the-processor.jpg\" alt=\"Replacing thermal paste on the processor\" class=\"wp-image-2512\" srcset=\"https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Replacing-thermal-paste-on-the-processor.jpg 500w, https:\/\/cpuforever.com\/wp-content\/uploads\/2022\/09\/Replacing-thermal-paste-on-the-processor-300x210.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure><\/div>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Final_Words\"><\/span>Final Words<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Cleaning thermal compound off of your CPU is pretty easy.
