The english Summers have been quite humid (nightime indoor temps in the late 20c's) and my Koolance case has been kicking in in the Mode 2 which is quite a bit noiser than when the fans are just running at 45% mode 1. So I decided to see what was available for a little modding, I found a nice little Radiator which is made for 80mm case fans (Black Ice micro) and I have put this into the top rear case fan hole with a 80mm case fan blowing out of the case. The radiator goes between the cpu block ((XP@10.5 x166 1.95v (anyone tried the 200w block? is it worth the money) and my gpu block (on a ti4200 clocked @300mhz). The net result is that in mode 2 the fans dont kick in (<35c ) even when playing games for a couple of hours and cpu temp are now at 48c max from the internal diode (epox mobo) and the only noise is a slight hum and my 10k scsi drive.
