CPU Overheating 100 Degrees +

Strength2000 · Oct 25, 2015

Hello,

I recently got a new CPU. The amd fx 8350. I had to send it back after a fault with a rattling fan. After I got a replacment, I put a pea sized blob of thermal paste onto the cpu and then put on the heatsink.

I checked all the cables and made sure none were in the way and tried to do the best cable managment I could do.

The temperatures were very very hot, unlike my old AMD FX 4100 which is an older make. I would think if I did have a problem, it would affect the worse CPU more. And the old CPU had barely any thermal paste on and loads of dust in the fan.

But idling, I get between 20-30 Degrees. I am not sure if that is good, but it sounds aright. I can play a variety of games, quite well, but when it comes to the more graphical ones, or I try streaming them, the temperature goes insanely high. I know these programs may not be accurate, but they have got to be to some extent.

It does not look good and I am wondering if the CPU is faulty or the Heatsink is faulty. Because I am tempted just to buy a new heatskin from amazon, as I only have the stock one at the moment, which is most likely not good for gaming, and may be faulty as were the other parts. What do you think I should do? Try and send the CPU back again? Or just buy a new heatsink? And what do you think the problem is?

Thanks

Jamie

I don't think it is a valid reading. There is no way a cpu to run above 100C. You can try this: When the program says your cpu is at 200C try touching the heatsink or at least put your fingers as close as you can to the heatsink and see if it feels like 200C. You understand that 200C is VERY HOT and you should understand if it is really 200C.

Done it. I agree, it does not feel like it is at 200 Degrees.

But when it says it is this hot on the program, my FPS began to drop. I looked it up and I heard something about the CPU tries to cool itself down so it is not working so hard.

You didn't really answer my question

Do you think it would probably be faulty, or I just need a new heat sink?

The main issue is when the program says the temp is a lot hotter than normal and the FPS seems to drop a lot which is frustrating?

So what do you think I should do?

Antonis117 · Oct 25, 2015

When gaming do you have an in-game hardware monitoring program to show you real-time readings? If yes try using it and see if the temps of the cpu cores is that high and if there is a frame drop. Also you will see what the gpu does when the cpu overheats.

Antonis117 · Oct 25, 2015

Before buying any coolers or returning the cpu we must see if it is a faulty cpu or something ealse.

I have a program, but it is not in game. I just go into windowed mode and have it open in the background, and as I said, when the temp goes up, the FPS goes down. Do I need an in game temp checking program?

Antonis117 · Oct 25, 2015

Which program are you using? Did you try any other? These 200C is way to hot and I am sure on what I tell you there is no way a cpu can run above 100C.

Antonis117 · Oct 25, 2015

There is a cpu self protecting "mechanism" which prevents the cpu from being damaged from overheating and it is set to shut down the system when the temperature exceeds 100C.

Antonis117 :

Have you got any you can reccomend to me? Because I tried a variety but could not really find an accurate one. I was using CPUID Hardware Monitor.

Antonis117 · Oct 25, 2015

try speccy and hwinfo.
https://www.piriform.com/speccy
http://www.hwinfo.com/download.php
I use these and they are very accurate.

Strength2000 · Oct 25, 2015

Antonis117 :

Alright, I used speccy. Worked fine at the start, but then got a big lag spike and checked temperature and it said it was 206 Degrees. All the programs I have used seem to cap at 206 Degrees.

And it always seems to be fine at the start and then all of a sudden out of nowhere a massive spike, and the temp goes up. My CPU orignally was around 50-60 Degrees until it spikes to 206 Degrees and the GPU was around 50 - 60 Degrees too.

I am really not sure what the problem is and it so annoying that I keep getting spikes. I am hoping amazon have not sent me another faulty product again....

Antonis117 · Oct 25, 2015

There are two things you can do. First try a bios update on the mobo. There is a possibility that it is outdated for 8350 and causes these anomalies. If this doesn't solve your problem you can try installing the cpu to an other mobo and see if it behaves the same way. If it is ok then something is wrong with the mobo. If it does the same after the bios update of your mobo or on the other mobo (on a friends for example) then it is a faulty cpu. But again 200C is too extreme. I also found this http://www.tomshardware.co.uk/answers/id-1821957/amd-cpu-reaching-200-degrees-celsius.html

Antonis117 :

I have updated to the latest bios, but has not seemed to help one bit. Plus I can't put it in a new PC as I have no one to do it with. Any other solutions or suggestions that you think may be causing the problem? And as I said, if it is getting hot, would a replacement be needed or is that just normal and I would probably just need a better heatsink? The strange thing is it used to work fine with my amd fx 8350

Antonis117 · Oct 25, 2015

I strongly believe it is a false reading because at 200C the epoxy on the cpu die would literally melt. If you install your old 4100 will it show 200C or a normal temperature. If it shows a normal temperature then the 8350 probably has a faulty thermal sensor.

Antonis117 · Oct 25, 2015

But my fault you said earlier it worked fine with the 4100.

Strength2000 · Oct 25, 2015

Antonis117 :

Yes, I understand that the reading is incorrect. But the FPS is annoying that whenever the temp goes up on the program, the FPS dramatically seems to go down. I want a fix to fix the FPS dropping. It should not drop if I upgrade processor. As the FX 4100 was more consistent but lower overall fps than the FX 8350.

All I need is to fix the FPS then its fine.

Thanks.

Antonis117 · Oct 25, 2015

Maybe just maybe the cpu reads that temp and starts throttling (believes that it is that hot and starts to drop frequency) and cuts the data feeding to the gpu. This may cause fps drop but I am not sure about that. It is just a very rare phenomenon.

Strength2000 · Oct 25, 2015

Im gonna get a replacement. Third time lucky! And if still not working and idk why, I will just get a new heatskin.

Antonis117 · Oct 25, 2015

The best you can do at this point. I hope you finally get a good 8350. As for the heatsink it is well known that their stock cooler is not that good (not to the point to hit 200C) but if you can get a decent aftermarkrt it would be better.

You ever think it is not your cpu but your mobo temp sensor? If it reads a overheating temp, it'll throttle your cpu.

Antonis117 · Oct 26, 2015

The motherboard sensor gives data to the reading "Motherboard temp". It is actually the temperature of the socket on which the cpu is "sitting". But throttling is decided by the cpu core temp and not the socket or the case temp. However if it was really 200C the motherboard sensor would show a high temp as well.

Benjiwenji · Oct 26, 2015

Well AMD cpu temp sensors are weird, they aren't real temps but are calculated.

Which is why alot of 3rd, party monitoring software struggle with AMD cpus

Use AMDOverDrive, the thermal margin seems to be the most reliable when under load (not idle).
