sukhoi core clock madness..........
mine 3870 stock fan speed also very scary on full load, 92oC @ full load...... incredible...but after pushing the fan speed to 60% quite ok it turns out to be, full load at around 60oC only

noise at 60% fan speed still quite ok, not very intrusive, so if enclose in casing it should be fine.... but what rpm i dunno it show in percentage only..
hoho i notice that only after i post.......... lazy to edit hehe .......
now must wait for non reference card design for a voltage bump to get some madness result......

shoul cut donw a frame or 2 at most at minimal, but at average still will be quite ok not noticeble..... the bottleneck mainly on the data transfer between cards only.

sapphire single slot seems to perform quite well......... i'm using the old dual slot version, it got power play feature with stock bios, idle temp is around 39oC @ 50% fan speed, during normal days, hot days it goes up a few degree.
anyhow i still like single slot, help to expel hot air out of the casing hehe....
