If the stock cooler is too loud, search for this little gem - Inno3D i-Chill Hawk Graphics Card Cooler. For 20 quid it looks great!
reviews arent that good tho from what i remember?
@ Fox have you messed with the custom fan profiles? I was thinking exactly the same as you 30 mins ago. My first attempt at a profile but its working really well. im idling at 45C ish @ 30%

didnt get that bad in 3dmark and didnt go above 70C
