This May give you an Idea on Temps with the XFX (i have this one
http://www.scan.co.uk/products/3gb-...700mhz-gddr5-28nm-gpu-1000mhz-2048-cores-dvi- )
The card is completely Default Out the Box and running with The Auto Fan function in Catalyst Control.
I Played Battlefield For 30 mins exactly on Ultra Settings, everything maxed out.
I reset this before i started playing so the Max Temps Show you what i Hit During Gameplay
[Taken @ 11:03]
I then Let it Cool at Idle for 10 minutes and it dropped to 32c
[Taken @ 11:13]
Overall im Pleased With these Temps, During gameplay when the cards at 40% fan speed its barely noticable and very quiet.
I dont know if this will help you, im just trying to show some stats of what ive got With the XFX for Reference.
