  1. I've got a couple of molex 8cm fans that cannot be rpm adjusted etc when the computer is on There a just on at full power when the computer is switched on. Is there any simple way (with the help of a couple of resistors perhaps) that I can rig up my fans so that they connect into the proper sys fan connection point on the motherboard, and hence have control of the rpm etc?

    get a fan controler.. its a little unit that fits in one of your 5.25" bays (cd/dvd bit) that has nobs and buttons and an lcd (if you got a good one) to show you the temps as well as let you set the speeds etc.. im also looking a shop in aus (preferably not online) that sells them... and they do exists
