Hello,

I'm not sure if this is the correct part of the forum, but that's my best guess.

I got a sudden 20 fps drops that do not get better until I've restarted my PC. I've been getting this for a while now (as far as I can remember buying the PC a couple of years ago). This problem looks totally random, but reproduces itself only when the PC is loaded. I've set SpeedFan to log pretty much everything and here's what I got (colored for easy tracking).

The time the drop happened is about 85698 (my guess is 85689 the correct time). As you can see, at that time all the temperatures start dropping. Do I have an issue with the cooling? Here's my hardware specs taken from cpu-z and gpu-z:

If it's cooling issue, why doesn't it get better after it has cooled down and a PC restart is needed?

If you have little to no airflow, opening the case would help. If your case has proper airflow opening the case should make things worse I'd imagine. A bigger box wouldn't matter.

If those temperatures are in Celcius, then I'd imagine that there will still be heating problems in the near future. But if opening the case helps the temperatures, just be sure to clean out the case of dust often.

You can see most of them in cpu-z and gpu-z reports, gut here they are (I've striped down the irrelevant stuff):

PSU: Turbo-X 650W Value Series
Mobo: MSI 970A-G45
CPU: AMD FX 6100
Video: MSI R7850 Twin Frozr
RAM: 3x4GB Corsair Vengeance

Got a CPU cooler, Arctic cooling freezer 7 pro v2 as well.

If you need more info, I'll ba happy to provide.

CPU temperatures as far as I remember (that's how SpeedFan reports them, I've not made the names up :D). 75 degrees is not too hot, is it? Even GPU 85 degrees should be ok or am I wrong?

PS. I'm going to take it for diagnostics tomorrow, if nothing else, I hope I can post somewhat of answer to this if the tech guys can find the issue.

So, I got the PC back, they have changed the video card, but the issue still exists, I'm pretty sure now it's my CPU overheating, gonna force the cooling at 100%... and I'll probably open the case :D

So, I believe it was really a CPU overheating issue, even if I couldn't test it for a long periods of time. I've tried both the Arctic cooling freezer 7 pro v2 and the original cooler, respectively with case closed and opened:

Arctic cooling freezer 7 pro v2 - 85 degrees, 61 degrees
Original - 75 (might be higher, have tested it for prolonged amount of time), 65-67 degrees

One more thing, Arctic cooling freezer 7 pro v2 fan can be positioned only downward towards the GPU or upwards toward the PSU (not even sure if it can be placed upward in my current box), what do you advice? It was positioned downwards till now.

Does having my PC opened leading to better performance mean I need a bigger box?
