CPU Temp over 80 degrees C

[ricksis]

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?

 

[badger906]

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?

Cheers

Paul.

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.

 

[ricksis]

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.

 

[ignatzatsonic]

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?

 

[Sardonicus]

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.

 

[essenbe]

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

 

[badger906]

if its cpuz your using ignore it. My cpu is apparently 92c at idle and my my gpu is 126c...

 

[search53]

I'm also suspecting it's showing Fahrenheit. 106 F is a very acceptable 41 C.

 

[lhorwinkle]

I'm with ignatzatsonic on this. If you computer is working properly, it's unlikely to have temps that high. The "thermometer" may be culprit.

 

[essenbe]

If he is reading temps i Farenheit, it is normal for this CPU. After reading some reviews on the CPU, everyone is mentioning the high temps.

 

[ricksis]

It's in Celsius. When i check the Fahrenheit box, it shows over 220 degrees. I use SpeedFan.

to ignatzatsonic: I would enter bios to check the temp, I don't know how though. I wouldnt care at all about the temp if I hadn't noticed a severe slowdown when using the computer. And yes, no overclocking.
Btw, i thought I kept this for another post, but after startup, CPU is at 100% without me doing anything. No scans, no backups, every program in the task manager list it's at 0%, still both the cpus are at max. This goes on for like 10 minutes, after which the usage drops to a normal 2-4% rate.

to p5bdkw: No BSOD. The fact is i had this problem, as I said, 3 months ago, when i had it to a specialist to be dusted. It simply shuts down when the temp reaches a peak level.

 

[Sardonicus]

It might be worth it to replace the CPU. They go for next to nothing on Ebay.

Could a virus or Malware cause a 100% usage at start up like OP describes? Could it be helpful to sweep system in safe mode to eliminate this as a possibility? It does sound like a mechanical problem though but system sounds like it is getting cool air and cooler is functioning properly.

I scanned the whole computer, thoroughly, with both AVG Full Edition and Malwarebites. Found nothing. Also went to user/appdata/local/temp and saw no *.exe.

 

[officious]

Sounds like a poorly seated heat sink with either too little or way too much thermal paste to me;

At least that was my experience (took me 3 tries to apply my own paste and set my heat sink and get it right, now with proper air flow i idle at 25*C or lower)

 

[essenbe]

What kind of case do you have? Is it well ventilated? I agree. it sounds like a bad heatsink, or bad installation. Maybe consider a third party heatsink. Some are not expensive at all. artic silver installation instructions. There are several methods.
