CPU overheating, how to deal with it ?\r\n\r\n\r\n\r\nHave you ever experienced PC hangs under heavy load or after some hours of usage? or sometimes your computer behavior become unstable? those symptoms happen because of many reasons such as\u00a0Virus infection, Power-supply defection or loose contact,\u00a0Hard disk defection or bad sectors,\u00a0RAM problems (Learn\u00a0how to check your RAM for errors) ..... etc, but one of the most common reasons is the\u00a0CPU overheating, and that mostly because either your\u00a0CPU heat-sink fan filled with dust or has expired so it cannot perform as good as the first time you purchased your computer.\r\nHow to identify if my CPU is getting overheated?\r\nTo identify if the\u00a0CPU overheating\u00a0causing your computer instability you can download and install for FREE the\u00a0SpeedFan 4.42\u00a0tool from the below button, it is so useful tool, hence I had a problem with my ex-fan performance and because of it I discovered that I'm having a\u00a0CPU overheating problem.\r\nDownload SpeedFan 4.42\r\nYou may see in the below screen shot that I got a CPU overheating specially when operating the AfterEffects and Adobe Premier software because as you know video rendering uses a lot of\u00a0CPU and\u00a0RAM resources specially when the video compensation is more complicated that uses a lot of filters, effects or motion.\r\nFrom the below image its obvious that my dedicated\u00a0graphical card (Video card) also getting more temperature, my card has a fan so I cleaned it and its problem where solved but the CPU overheating problem remain the same.\r\n\r\n This tool has many advantages and not only showing the CPU temperature \/ CPU overheating, you may visit the SpeedFan original provider from this link \u00a0https:\/\/www.almico.com for more information. \r\n Note: It's important to mention that from my experience I applied the below steps to similar cases in the past and it did solve the CPU overheating problem, so if you are capable to follow the steps I recommend try them out then check the result as a first option in case if you don't wanna lose money by purchasing new components such as the heatsink or new fan. \r\nHow to check and clean my CPU fan\/heat sink from dust?\r\nIts easy, follow the below steps:\r\n\r\nFirst of all you need to wear the wrist antistatic charge strap (recommended).\r\n\r\n\r\n\r\nIf you don't have the antistatic charge strap, open the PC case cover and while the power cable is connected to the power plug, touch by your fingers the body of the Power supply for a second.\r\nUnplug the power cable from the wall outlet power faceplate.\r\nNow, you need to take out the fan with its heat sink from its position on the CPU along with the fan fixed on it.\r\n\r\n Note: Read the instruction that comes with the heat sink package to understand how to take it off because there are several types of CPU heat sinks. \r\n Note: If you haven't done this before you need to ask someone with experience to avoid damaging the CPU because sometimes the heat sink sticked to the CPU by the thermal grease "The thermal grease is attaching the CPU body surface to the heat-sink surface" if it is sticked you may need to use a hair drier to heat the area for a while in order to take off the heat sink. \r\n\r\n\r\nNow you need to separate the fan from the heat sink.\r\n\r\n\r\n\r\nBlow the heat sink using an air blower, and if still some dust that is sticked between some gaps try cleaning it using a small brush (like tooth brush or so).\r\nAlso blow inside the computer case to get rid of any dust over the rest of the components.\r\n\r\n\r\n\r\nNow clean the fan using a brush.\r\nTake off the small round sticker on one of the fan sides and put one\u00a0SMALL\u00a0drop of grease, stick back the round sticker and be sure to stick it well as if you don't stick it back the grease you put will collect dust and will make the performance\u00a0worse\u00a0over time and the problem of CPU overheating will raise again.\r\n\r\n Note: Use the grease that comes with hair cutter machines or similar ones, and NEVER use the cooking oil. \r\n\r\n\r\n\r\n Note: If you don't have the proper grease skip this step, this step might enhance the fan rotation speed in case of any friction on its core node. \r\n\r\nClean the heat sink surface from the old thermal grease, as well as cleaning the CPU surface using a piece of soft cloth or a tissue.\r\n\r\n\r\n\r\nFix back the fan on the heat sink.\r\nYou need to have a new thermal grease which you can get from the market.\r\n\r\n\r\n Note: For the grease\/paste\/gap-filler, try to get the one that contain metal in its combination which normally gray colored, don't use the white colored one like the one comes with the intel CPU package, Arctic Silver 5 is recommended. \r\n\r\nApply the thermal grease on the CPU surface, don't put too much grease just follow the instruction that comes with it, the heat sink pressure will spread the grease over all the CPU surface.\r\nFix back the heat sink on the CPU after applying the thermal grease.\r\n\r\n Note: Follow the fixing instructions that comes with the heat sink package. \r\n\r\nNow plug the power cord into the power outlet and power on the computer.\r\n\r\n\r\nHow to enhance the PC case cooling?\r\nIn addition to the above steps you can add more fans inside your computer case in their appropriate locations to increase the air flow inside the PC case, in a way that lead the air flow to go towards a specific direction so you need to place the fans rotation direction to make the air flow in a specific direction, for instance the front fan get the air from outside the case to inside, the other two fans getting the air from inside the case towards outside or something similar.\r\n Did you know that you can\u00a0POST your comments below !!
