Re: How do you remove the heat sink from the CPU?
This depends on the CPU and the heat sink. The heat sink is fastened to the socket on the motherboard on two sides. It will be fastened to a tab on each side. In all likelyhood, the heat sink will have some sort of handle on it. AMD processors these days have a little lever that must be moved from the far right position up to the center. This loosens the heat sink and you can reach down to unhook first the side with the lever from the socket and then the back side. Intel processors seem to have a flat metal piece that must be pushed down to relieve tension on the clamp. As you do so, you have to get down by the socket on the motherboard and push the metal clamp away from the socket. This takes some doing, as it's quite tight. Once you have released the one side, the second side is loose and can be unfastened. The heat sink can now be pulled up (use a slight twisting motion if possible to break the seal between the heat sink and the CPU. If the computer is several years old, the seal will be hard to break.

1. Stop Overclocking your CPU 2. Make sure your Heat Sink is placed properly above the processor 3. Clean the Processor fan, Heat Sink and other peripherals 4. Use High Speed fans 5. Use CPU Heat Sink Paste in the processor 6. Make sure your dint restrict the speed of CPU fan. 7. Use Additional Cooling Units 8. Check your SMPS 9. Use proper ventilation in your room 10. Shut down your computer at least two hour a day Let me know if it helps you. Use system utility tool like RegInOut to remove unwanted files , fix registry and windows errors which cause of heat problems
When the CPUoverheats it goes into thermal shutdown and will not boot up again until theCPU has cooled down. The heat sink may be clogged with dust, which causes the CPU to overheat byreducing air circulation through the heat sink.When you replaced the CPU fan, did you put new thermal heatsink paste on the CPU/heatsink? If not then the CPU can overhest. Your computer fanmay be faulty and not spinning freely, in this case replace the fan. Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust.
Check the CPU cooling fan. It is running, and if so, running correctly? Check the heat sink for the CPU cooler. They get clogged with dirt and cause overheating. Use canned air and blow out the heat sink to clear it of dirt and debris. DO NOT remove the CPU cooler to clean it. There is special thermal material on the heat sink to properly transfer heat. Removal will damage this and render the fan ineffective unless you have replacement materials available.
You can usually check the CPU temperature in the BIOS to ensure that the cleaning effort has worked.
The CPU Heat sink (the big metal block with a fan) may not be making good contact with the CPU surface area.
Thermal compound may have not been applied between the CPU surface area and heat sink
The heat sink and fan are not sufficient enough to cool your CPU
Dust buildup is not allowing proper circulation of cooling air
If this system is not a name brand and covered by warranty then I would remove the heat sink (carefully) and verify that the mounting bracket is not broken or loose. I would check that ample thermal compound is applied, and if not use rubbing alcohol to remove all compound from the heat sink and CPU and purchase a tube of compound to apply yourself. I would also thoroughly clean the heat sink with compressed air.
If the heat issue continues then you will want to consider upgrading to a more powerful cooling solution.
The CPU fan should run constantly but in some systems will run between 50% and 100% speeds assuming a variable temperature control is applied to the system via motherboard or third party installation.
When the CPU overheats then it will shutdown (i.e. thermal overload) and won't boot up again until it has cooled down.If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust. Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear
and dust free. Use acan of compressed air to do this.
If your CPU is sticked on the heat sink due to heat sink cement, could have damaged your CPU pins. Those CPUs like AMD and IBM Desktops we need to unassembled the same by tilting method. If your CPU pins are damaged, remove your CPU from heat sink by the help of a chisel type screw driver and clean both faces of heat sink and CPU. Do not scratch, use isopropyl alcohol to remove heat sink cement. Inspect any pins are dented or damaged. Align pins, if broken solder with help of a goldsmith. Reinsert the CPU in motherboard socket, apply a little portion heat sink cement in cpu face and re fix heat sink and recheck the motherboard.
Hi there! AMDs (some of them) have Overheating issues. Your default BIOS is set to protect the CPU chip in case of overheating. It will do so by shutting down the computer. You can hold "delete" key on boot to enter BIOS. Go to "PC Health Status" or " Hardware monitor". Here if you see temperature exceeding 60 degrees or more, this mean it's OVERHEATING! Now the first thing is to check if your CPU fan is running & is well secured with the lock. Try to move it to see if it's loose. Secure it properly to solve. If it's not running, you'll need to replace. However if it's not the problem, remove the fan & its aluminum heat-sink with CARE. Then re-seat the heat-sink properly. Note that a poor contact of CPU & heat-sink = Very Hot CPU & cold heat-sink. If it's not the case, therefore remove the heat-sink & clean the old thermal paste on it & the Cpu chip also. Apply proper thermal grease e'g Arctic Silver. If the above does not solve the issue, you'll need to replace fan. (pls check with another one before buying a new one if possible) Ultimately if the issue is not solved by the above, this means that the heat sensor on the motherboard is faulty. Here motherboard needs replacement or warranty services. Hope this advice really helps you. Please remember to send us your valuable feedback as it's very important for us!
Overheating problem Remove case side and clean all fans remove fan from heat sink usually 4 screws or little clips Do NOT remove heatsink stuck on with heat paste clean vanes in heat sink replace fan use stiff brush and vacuum cleaner to clean outside of power supply vacuum out case include all vent holes reboot computer should work ok replace case side
Hi oilian, Be glad it did shut down. If it didn't, your new CPU could haveover heated. There are a few reasons for a CPU to over heat. 1.) There is no thermal grease or too little on the heat-sink assembly. 2.) The old thermal grease was not removed or the old thermal tape was not removed. 3.) The heat-sink assembly was not cleaned completely with alcohol before applying new thermal grease. 4.) The CPU fan is running too slowly. 5.) The heat-sink fins are possibly filled with dust build-up & the CPU fan can not cool the heat-sink assembly. Boot to the bios & go to Hardware Monitor. There you can check voltage, CPU fan speed, CPU temp & other bios monitored settings.
