well , whats all of a sudden , you start talking about a different pc and then ask about this one , forget the other pc , what was the normal of the problem pc , has it always ran hot ? did this just start doing this ? has this been a problem from day 1?
what are your ambient temps ? what thermal paste and applied method used ?
Sorry if i messed you up,
things are pretty clear
2 individual rigs,
both on Sabertooth FX990 R2.0
both with FX8350
both used to be in stock cooler
one of them still runs on 38-40 currently on idle at 20-25C ambient temps
the other one started overheating since 5-6 months ago with the temps i wrote down on the previous post.
For the sake of simplicity, lets call the one with the normal temps "HD5870" and the one overheating "V4900".
thermal paste used is the one included in the artic cooling package, which is supposed to be outstanding. Applied method as advised in instruction leaflet.
try a repaste of the over heating pc , I wont refer to the other pc unless it becomes an issue later on , make sure to clean all the paste off and apply some good quality paste ." i personally use gc extreme as its outstanding performance and is none corrosive/ conductive " and personally i prefer the pea method for its simple yet effective installation
There is no need to refer to the other pc because it was used as an example of a fair equal system with no overheating side effects.
I did 3-4 repastes before and after buying the aftermarket cooler for obvious reasons using the paste included and other same type none conductive pastes which i have used to numerous other CPUs with no problems. I use the pea method as well because it spreads equally but i also used the 3 lines as instructed on the aftermarket cooler leaflet instruction manual.
I've already crossed out any configuration related problems and keep in mind i'm experienced.
Also i used to be an OC enthusiast so i know things related to thermal output siphoning and i'm not looking into better performance right now, just keeping the cpu cool.
good to hear , then its down to vcore and actually cooler being used , these are easy to debug .
