My CPU Heat - Computers & Internet

Try blowing the dust out of the inside, around the vents, around the fans and by the cpu and heat sink.

Also remove the fan as it sits on the cpu and heat sink. Then remove the heat sink that sits on the cpu, then remove the cpu by releasing the latch on the side of the bay it sits in (remember how the cpu goes back into the bay). Now clean off the old dried up thermal paste on top of the cpu and on the heat sink that sits on the cpu. Put the cpu back into the bay and secure the latch. Apply a fresh coat of Thermal Paste to the CPU and Heat Sink. Put everything back together then reboot.

If the thermal paste has dried or is too thin to keep the unit cool it's like metal touching metal and shorts out the system so it can't boot.

You maybe over clocking the cpu, friend this the reason why the cpu heat in that amount of heat. Reconfigure your motherboar and set it into default configuration so that the cpu speed is back to normal...
If the problem is still exist. Buy a good new one cooler fan to minimize the heat the maintain the good speed of the processor

You can fix it yourself. The CPU was to hot and the solder has come off. Bad part is the solder is under the CPU and must be heated up. It is lead free so it needs more heat then lead and you need to add flux. I would start by getting the board out. Remove the thermal paste off the CPU. Add flux with a flux pen. You want to get the flux under the CPU so you might want to tip it on its side. After you have a good amount of flux under the CPU you want to start to heat the parts around the CPU. I would use a heat gun with temp. settings. You first want to heat around the CPU to keep solder on the other parts from cracking. You dont want to over heat the parts. After you preheat the board you want to heat the CPU. It needs to be around 400 or 500 degs f. a good 15 or 30 sec. keep moving the heat gun. After heating the CPU you want to start the cool down. Same as warming up the board but you want the board to cool down slow. After all this you want to add New thermal paste to the CPU. This helps transfer from the CPU. This is a must because your PS3 is overheating as it is. After you do all this some people say it only works for 2 to 6 weeks. Its all on how you fix the board and how good of a job you did. I would back up your hard drive. Then hope for the best!! good luck and i hope this helps you out.

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.

Replacing the fan on the CPU or the GPU, Graphics card, is actually very simple and the fan will run about $20 to $25 depending on what type of fan you get and where. Aside from a new fan you will need a small tube of heat sink compound. The fan just clips on to the CPU. Make sure you get a fan that is designed for your CPU type or it will not fit properly. For instance, if you have a P-3 CPU you can't fit it with a P-2 Chip or P-4 chip, they won't mount correctly and subsequently they won't work. When you go to Best Buy or the computer shop your to buy your part tell them what type of CPU you have and that you want the cooling fan and the heat Sink Compound to mount it with. They will be able to direct you to the proper fan Type. Also, while you have it opened up take the opportunity to use canned Air to blow the dust out of the machine. If you are doing what is called Over Clocking it is important that you know you may have burned the CPU out as this causes the CPU to heat up more than it would if you just had it installed for the proper speed. The old fan will be difficult to remove because the old heat sink compound will have formed a bond between the fan heat sink and the CPU itself. If you have to do any prying to remove the old fan make sure you do so carefully and make sure you clean the old heat sink compound off the CPU before you try mounting the new fan. When you apply the new Heat sink compound you want to place the compound in the center of the CPU and let the heat sink spread the compound out in a thin layer. This compound needs to be spread evenly so it forms a good bond between the Heat sink and the CPU itself to properly transfer the heat from the CPU to the heat sink so the fan can properly cool the CPU.

There can be many reasons of unexpected shut down of your system.Below are some remedies to solve it

1
Run an anti-spy ware and anti-virus utility to make sure that the shutdowns aren't being caused by a malicious program. If the shutdowns are infrequent, install a CPU temperature monitor utility to keep track of the CPU's temperature. If the CPU is overheating, or the shutdowns are frequent, then you will need to troubleshoot your computer's internal components.

2
Check any recently installed internal components to ensure that they are properly connected to the computer's motherboard. Make sure any new expansion cards or memory modules are securely seated in their slots, and ensure that the power and data cables are properly connected to any new drives.

3
Check for large dust buildups on your CPU fan. If the fan isn't effectively cooling your CPU, the overheating CPU will cause your computer to power off. Carefully pick away large pieces of dust with your fingers, and then spray the CPU fan with a can of compressed air to remove the rest of the dust.

4
Reapply the heat sink compound between the CPU and heat sink if the computer continues to turn off unexpectedly. Heat sink compound is a pasty substance that fills the space between the heat sink and processor, which increases the heat sink's ability to absorb heat from the CPU. But worn heat sink compound won't properly redirect heat away from the CPU. Power down your computer, disconnect its power cables and open the case. Unplug the CPU fan's power cable from the motherboard, remove the heat sink and fan combination from the CPU, and then apply the heat sink compound to the CPU--refer to your product manuals for details on reapplying heat sink compound.

Thanks .
Have a great day.

Hello,

Your Laptop seems to be full of dust - Maybe your CPU Heat sink FAN cannot turn because if this THUS causing your laptop to heat up and shut down again to prevent your CPU from receiving damage due to high temperature.

Close your laptop lid, then put the unit on its backlcd. Make sure you disconnect the Battery and the A/C Power chord. With the emty battery slot is facing you, take note of the screw that is facing you to the right on the bottom cover. There might be others like this in the same area. The cover that you need to remove is of rectangular shape, and the largest cover.

When you have removed it you should see the CPU Heat sink and a FAN. This is the part where you blow the unit out at that spot with compressed air so that the dirt will no longer block the heat from venting away from the laptop mainboard/cpu.Please check if the CPU FAN is still turning licenly. If it doesn't turn or very difficult - replace .

[ADVANCED]
Then, remove the 3 screws from the CPU heat sink and thereby remove the HEAT sink completely. Remove the CPU Heat sink FAN and clean it as nessesary. Use a small flat to switch the CPU from closed to open and remove it. Then clean it with a cloth and ethanol - make sure you remove all dirt and old heat sink paste on top if it. make sure you do not touch the bottom of the CPU and handle the pins carefully.

When you are done, place the CPU back and reaaply a eyedrop of fresh heatsink paste onto the CPU, lock the CPU switch again. Then clean the backside of the CPU heat sink where it rests on the CPU. When you are done with that, place the CPU heat sink back onto the CPU then screw the 3 screws back onto the CPU heat sink and onto the mainboard. Keep the sequence in mind. Reconnect the CPU Heat sink FAN to power on the mainboard with the cable then place the cover back onto it. Tighten all screws again and reconnect battery and A/C Power chord.

Neither.

Turn the computer off.
If it is a HP laptop, remove the battery.
Disconnect the AC power.

Buy a can of compressed air, and give your computer a "blow-job",
to blow all the dust away from the heat-sink on top of the CPU,
and also, if it is a desktop, from inside the power-supply.

A layer of dust is a layer of insulation, preventing the heat-sink on top of the CPU from "radiating" the heat away from the CPU. So, your motherboard is detecting that your CPU is "too hot", and automatically speeds-up the cooling fan, to try to move the heat.

clean the cpu cooler slots and replace the thermal compound on the cpu ....make sure you clean off the old thermal compound .....only a thin layer of new thermal C will do all most see through ... hope this helps my friend
