i got an AMD FX 8350 and a Lightech 120X (Version 2 with the fancy fans) and i was watching films.
So i decided to switch to passive mode (Just the pump and two frontfans runs, the CPU runs at power saving mode) in winter this is not a big deal but i wanted to know how it works at this ridiculus temperaturer here in germany (35°C +. in my room even more). So after 1 hour doing stuff i hit 65°C.
I think this is not a big deal for the CPU but later i forgott that i am on passive mode and started gaming. After about 3 hours (or more) i remembered that i maybe should check the temps and wanted to switch to High-Performance mode (All fans on my manual powercurve, in this temprange all at maximum power) at this moment the CPU was about 85°C. When switched i think the CPU gets overclocked because the game runs in the background and the temperature reaches 85+°C. The Computer shutted down instantly due to unhappiness.
In that moment i opened the Case as fast as possible and blow in it with a 100W windmachine to cool it. Afer 30 Secs i was able to start it again and the temps where at 47°C.
I don't know how long the CPU was at this high temps, but maybe a long time.
Did i damaged my CPU by my own stupidity? Should i renew the thermal paste?
And by the way: What temps are ok for this CPU? I heard it trottles down at about 62°C so should i take care not to reach that? What is the best temprange for it? I could cool it down to about 43°C at all time (full load and summer) but then the neighbor thinks i am testing rocket-engines for ICBM's and i dont want him to call the police.
And what about the GPU? I never hit something over 90°C (is that ok? Whats a good point for a Radeon HD 7870?)
(I love my pc (fist build and first "real" pc) and i dont want to upgrade it for a longer time so the CPU should last long)
thank you guys.
PS: Sorry for the stupid questions... But i trust you guys much more than "the internet"
If it boots fine it will be fine. 85C on an AMD chip is not all that high. If you hit 90C or 100C you should worry. But usually the CPU will auto kill itself to save itself.
Under my own stupidity, I have actually overheated a CPU before, I ran a rig without the CPU fan plugged in. It auto-killed itself and being completely new at building computers I just booted it up again till it killed itself a second time. That CPU does have damage, but it still runs though it is fairly unstable.
Thank you VXAce... I read some other stuff about that.. Things like "You hit 70°C? your AMD CPU ist dead"... But obviously i dont trust it. I knew that new CPU's protect themselves by trotteling and emergency shutdown but 85°C is not my comfortarea...
And what about the long time temps? Does it really trottle down above 62°C?
A CPU tends to throttle at around 70-80C depending on the manufacture and your settings in bios. I think AMD starts at 70C. But both AMD and Intel can turn off the throttling in the bios, risky, but some OCers do it.
A long time safe temp for me is about 60-70C on a desktop and about 75C on a laptop. But I have very little control on a laptop.
Here is that rig that I burned the CPU on rendering a thing, for hours at whatever temp Speedfan says. And it still works.
but honestly i dont think you can compare a laptop CPU with a desktop CPU. At least in my Laptops i can't really control the fans or keep the temps in a suitable range. By the way: What CPU is it? I heared that Intel CPU's trottel at about 105°C (https://forum.teksyndicate.com/t/how-hot-should-i-let-my-gpu-cpu-get/30332/4)
And the rule: AMD: not above 60°C Inte: not above 80°C. In you laptop should be a intel so the temps are kinda ok for me, but for an AMD that would be too much.
My laptop is running a i7-4700MQ on a cooler that can barely keep up with it. The image has a... Phenon II X6 1055T? On stock cooler? I think? My "main" desktop has a FX-8320 on a 212 Evo which runs at about 50-60C under load. And my main gaming desktop runs a G3258 (with a reasonable OC, not the max I can get out of it) which maxes out at 70C on a stock cooler under load.
Not a bad rule, but I do Intel at 70C on a desktop during stress testing. That way when I game and everything else heats up, it'll be just fine.
Should be fine champ. It would just throttle itself to save it from damage. The TIM wont need replacing but if you have some handy and you've got spare time it never hurts to change it out every now and then.
