Windows 7: CPU Temp over 80 degrees C

CPU Temp over 80 degrees C

Hi. I've been lately noticing outrageous temperatures on my CPU. When in idle, it rarely drops below 80 degrees, and when playing/browsing/basically multitasking and the CPU usage goes over 50%, it peaks to 105, 106, 107 degrees. I know I should be worried, and I am. What can I do? Dust the fans off? Other solutions?

dust off the fan, check that airflow isnt restricted, and that any vents/panels arent obscured.

It could be that the TIM on the heat sink was poorly applied and or of poor grade. it might be worth buying some new thermal paste and reapplying it, but it would also be worth investing in an aftermarket cooler while your at it.

But if this is a laptop(as it isnt stated) then similar measures need to be done, but its far greater work. plus not all laptops use TIM, ive worked on a few that use other methods but meh.. i wont go into that

Hi ricksis,

Can you give us some more info on the system.

As badger says, Laptop or PC?

What model if you bought it ready made? And how old?

It's not a laptop, it's a desktop pc. it's pretty old, I think I bought it 5 years ago. The thing is i did all the things you guys said recently, like 3 months ago. I went to a specialist at a well-known shop, he dusted it off, replaced the thermal paste and did everything he knew to clean it. and he did clean it. An yet now I have these huge temperatures, and my pc is getting laggy and operates slower and slower as the days pass.

I'll be updating with the system hardware specifications, if that is what you require.

No CPU should idle at 80. With the computer running, make sure the CPU cooler fan is turning properly. With the computer off, make sure the CPU cooler is firmly attached. It should not move with moderate pressure on it. make sure you have good ventilation in the case.

I checked that. The cooler spins correctly. It's firmly attached with those 4 pins by the motherboard. It's cold outside, I've just opened the window so the air can fall on the PC, and I see it's got down to 70 degrees. And I'm just running Mozilla and 2 Word docs.

If the CPU cooler is properly attached and has a halfway decent application of thermal paste, I'd suspect an erroneous temp reading.

Are these temps as reported in the BIOS or from a software application or?

I assume no overclocking?

Are you sure it's centigrade?
80 C is 176 F
70 C is 158 F
107 C is 224 F

At 107 C, 224 F, your PC would be prone to a BSOD.
The fact that you didn't mention any BSOD's is odd.

Tcase on your CPU is 67.7 which should make TJmax(which you are reading) I'm guessing would be around 77-80. At that point the CPU should start throttling down or BSOD as p5bdkw said. Go into BIOS and see what hardware monitor says. See if that is a similar reading.

Also, what program are you reading these temps from? Try Coretemp or Real temp

CPU at 235 degrees F
Hello, I just installed Speccy, and was horrified to find that my both cores of my 2014 Lenovo ThinkPad are running around 235 degrees! And that's with nothing running except normal boot programs. I've opened up the bottom to check for dust, but the laptop's still only about a year old, and...

CPU and Motherboard Temp over 80 degrees C
Hello. I have lately been noticing the temperature on my CPU and Motherboard is really high. Its usually 70 degrees C but once I start gaming and code Java in background it will go up to 80+ degrees C. I am really worried. What can I do to prevent this to happen? Why does this happen?

CPU temp of 94 Degrees Celsius!
Hi folks, I got a bit of a shock when I just opened Speccy to see how my graphics cards were going, because they (2x) generally run on the "warm" side (one at around 60C and the other around 80C) ... which, even though this PC was built "professionally" and has quite a number of fans ... is quite...
