Hi folks, newbie alert. I have a HP XW8400 & HW8200, yes old school. The 8400 has a single Xeon dual processor, 3.66Ghz but another free 771 J socket. Thinking of putting another proc in there but ive only got 1 heatsink. Could i take both the heatsinks from the XW8200 that is running 2 Xeon Hyperthtread processors in 601 sockets? The 8200 processors had a TDP of 130W but the 8400 were only 65W. So i presume that the old XW8200 processors ran a lot hotter then the Xeon processors 2 years later and as such the heatsinks would be fine, maybe even overkill. Would they be compatible? Cheers for any advice.
