Apologies for posting in the wrong forum, theres so many of them and I never got to bed... lol, anyway... this PSU is only for an xp1900 server with 1 hard drive and 1 cd-rom, my main machine has a 560watt thermaltake
But good idea on the fan change.... guess it shows how tired I am

*Edit, just remembered why the Q-Tec would be quieter, it uses 2 lower RPM fans the HEC uses 1 fan *
