It's hard to say exactly, as I don't have anything to measure the temperature. However, it's summer here in Australia and the days on average are around 35c. I have a fan on in my room, but I doubt it would bring it down much beyond that.
Yes, I realised that, which is why I killed the game as soon as I noticed. It's kind of scary, that it's reaching those temps. When I originally bought it (I think March or April) on load it was 75c ish, so something has definitely gone wrong. I will take it out and clean it as you suggest and re-apply the thermal paste. I will report back with the results.
Thanks for looking into it and for the advice.
Even at that ambient temperature (say ~28-30C indoors going by the temperature outdoors)
It still is a tad hot.
I don't think you'll need to re-apply thermal paste if you think it's too much of a hassle. Cleaning out all the dust inside (cpu fan, gpu fan, chassi fans) will give you better temperatures, more so than re-appling paste.
If you somewhat hit -5c/+5c idle and load when comparing to other users you'll be fine.
But if you notice artefacts and crashing while/when gaming it's best if you just turn the comp off and let it cool down.
What chassi do you have? IIRC, best way to optimize air flow would be:
Front fan(s) as intake.
Top fan (if available) outtake.
Rear fan(s) outtake.
Chassi side plate fan, intake.
a simple push-pull config basically,
When did you notice the increase in temperature? Was it because of the change in ambient temp, or did you just notice it?
Do you remember the temperature during idle/load before?7
EDIT:
If you think software could be the culprit (drivers and such), remove and uninstall all gpu drivers. run driver sweeper in safe mode, and reinstall latest drivers.
I doubt this would make any difference but i might as well mention it.
Cleaning the whole computer out (removing dusts and such) should be the first thing to do.
