Hello everyone.
Bought the card in title about a month ago, and it's quite satisfying, giving me a silent but smooth gameplay in many games my previous XFX HD 6870 simply couldn't handle well enough. Yet VRMs are bugging me...
The web is practically filled with people reporting high temps for VRM 1. I've been monitoring them via GPU-Z, and for some reasons I'd like to understand, temps vary greatly depending on game.
Some examples:
Witcher 2 maxed out @ 1920x1080 (ubersampling off) reaches 100°c in around 5~10 minutes;
Borderlands 2 maxed out @ 1920x1080 (physx off) stays between 70° and 85° (depending on game's area)
CoD: Ghosts maxed out @ 1920x1080 (physx off) hardly ever goes over 80°c in around 2 hours.
Card's dual BIOS switch should be set to performance mode I think, as I don't see any locked settings from CCC.
Formerly, I'd like to know the max temps for VRMs for this card, and obviously if 100°c is a value to consider safe to keep on gaming without having to alt+tab for cooling. I could manually increase fan speeds, but would it help?
As a curious noob although, I'd also like to have a simple explanation of why temperatures vary so greatly and what impacts them the most, other than poor airflow or badly placed coolers (from what I've read).
Thanks in advance anyone for your answers!
