Can high CPU temperature damage motherboard?

Question

I built my own PC system about a week ago and it was running fine for a day then it shut down and never turned back on no matter what I tried , from what I remember the CPU temperature was 90 degrees Celsius and I know its a rookie mistake to have not taken care of that , my cpu appears to have no damage I just need to know if it killed my motherboard?

Answer 1

Depends. More information is needed before we can assume either way. When you say it wont turn on does it do anything at all when you press the power button? If you hear beeps the beeps can help identify what may be damaged by looking up what they mean. They could indicate the CPU is fried. No beeps could sadly mean your motherboard is toast. If nothing at all happens then it may just be the power supply. Test these first before getting a new motherboard. And look for any transistors that may appear burnt.

Answer 2

The Temperature is pretty high but it simply cannot result in burning the CPU nor the Motherboard. Check out the Power Supply.... If nothing happens when you press the POWER button, then there must be a power issue..... May be the Power Unit is fried due to some change in the domestic power supply or may be there is a problem with the power switch... If the cooling fans turn on but nothing happens, no booting nor displaying anything, no beep sound, then your Motherboard is gone...... you may need a replacement. A CPU is Hardly get fried and 90 degree Celsius doesn't damage a CPU.... and there is a system in the CPU to immediately restart the system in case the temperature goes above the prescribed range... So don't worry about the CPU. A voltage deviation on the domestic power supply can burn the Power Unit and even the Motherboard...... Overheating simply doesn't do that as the manufactures have taken precautions for their Motherboards and CPU s to automatically restart or shut off in harmful temperatures.....



P.S - If you have an old motherboard, that do not have emergency cutting off systems, then overheating can damage the CPU and MB but not 90 Celsius.

Answer 3

High Cpu Temperature

Answer 4

high cpu temperatures can ruin both motherboard and socket the max temperature you should be considered acceptable is round 70c for most processors



mine rarely hits past 60c



amd processors tend to run hotter and need a decent heatsink of 4 to 6 heatpipes depending on the type they are



65 dtp rating should have 4 heatpipes



95 at least 6 heatpipes

and 125w is better with water cooling

Answer 5

High CPU temperature can damage the motherboard but it has to go at least over 300C and no processor will allow that.

Answer 6

Check the circuits around the processor and the cpu socket for burnt marks 90 c is pretty high could of damaged the motherboard if the temps stays at or above 90 c

Answer 7

most motherboards have a thermal cutoff so they simply switch off, 90 degrees sounds high but for a CPU its not the max. Odds are though if its not turning on its something else altogether, did you short something on the case or have the power in wrong. Try a bit of trouble shooting before assuming it was heat.

Answer 8

A temperature alarm will cause a HARD LOCKOUT feature of the system.

Many OEM's like DELL build this safety feature in so you CANNOT melt your CPU

unless you are really really determined to do it!!!!

It may wait more than 45 mins before it lets you press the ON button with any success.



wait for at least one hour before trying to restart the system.



Do NOT assume the system is broken it may be absolutely fine.

Answer 9

Most motherboards have safety cut-offs to protect the MB and CPU. Sounds more like it might be bad power supply , maybe check power supply connections? Or maybe you are luck and just need to clear the CMOS using the clear CMOS jumpers. Just look for a youtube video on clearing CMOS.

Answer 10

If you did not properly apply silicon heat sink grease to the underside of the CPU before inserting it into the MOBO CPU socket, then the CPU may have fried. Your MOBO may still be ok but the CPU may be out to lunch!

Answer 11

in extreme situations it would be possible. but, i had a severe CPU overheating problem and my cpu could get to nearly 100c at idle. it was like that for months. after fixing it, i've had no permanent side effects. so it won't happen in most situations.

Answer 12

just done this... I overclocked a crappy i7 to 4.1ghz and the heat killed both motherboard and cpu.. water cooled.. next time I will go to AMD cpu and mobo.

Answer 13

Yes, it can melt through the pins on the mobo.

Typically, you will get a BSOD before anything like that ever happens.

Answer 14

yes, if it reaches the right amount of heat, the CPU is directly connected to the mother board.

Answer 15

return Acer laptop to factory settings

Answer 16

It,sure,can.All laptops have overheating protection.

Answer 17

Yup. It will be fatal

Answer 18

please check under the cpu fan thermal paste.high temperatue will destroy the cpu.

Answer 19

mayb

Answer 20

yes.
