rather than hijack the 8600gt in a hiper chassis thread - I have posted here.
Ok, everything was too hot and noisy in my case so i have water cooled it.
I have used thermaltake blocks cl-w0088 w2 water blocks for the 690g northbridge and 7600gt.
I have used a alphacool gps-07t gpu cooler with right angled fittings on the x2 5000 overclocked to 3.0ghz.
45deg c idle. 65deg c load - but quiet!!.
did have an alphacool nexxxos xp when i was on the 2500xp processor. However, because of the extra hieght of the IHS - i couldn't get the lid back on the case. Pics to follow shortly
