hi i have a intel 950D processor, can anyone tell me what socket type this uses??? is it am2? 939? 940?? ive no idea

buy one from Zalman - fits on every socket (there are some reasons it might not fit, but I've never seen a motherbord where this is the case). Look at their page, there is a short film showing how to mount it and in which cases it doesnt fix. Furthermore they make the best CPU Cooling u can find (me: P4 3GHz; intel originel cooler 80°C @3GHz while playing; Zahlman 120mm Cu: 55°C @3400MHz while playing^^)
