my system is
ATI Xpert 2000 Pro 32mb
IBM Deskstar 60GXP 40GB IDE 8.5ms 7200rpm
512Mb PC133 SDRAM
ECS K7S5A Socket A (SIS 735)
AMD Athlon 1GHz 266 FSB
with a Coolermaster DP5-6H51 on top
and the CPU was around 45-50c and the system temp was at about 37-40 ish. I brought a new fan Coolermaster 80x80x25mm DAF-B81 Case fan.
I have install it as an intake fan. This does not sheme to have done much to the temp.
Should I turn it aronud to make it an exhast fan?
