As a fun test in an old/unloved dual CPU Xeon system, I removed the fan for the heatsink and after 1.5 hours, the system was completely stable and had surprisingly not crashed, despite exceeding or hitting the critical thermal levels........

I've got one of these for testing projects from work at home and got more than I bargained for with the time I've spent on it due to the storage handing/Perc 6/i cards. My particular model came with the following: 2U Rack Mount Server with Rails 2xOpteron 2373 EE (Quad Core, there is a 6-core version that can be found at times) 16GB RAM 2 x 250GB Seagate SATA 2 x Dell Perc 6/i (horrible and a nightmare to work........

I bought a Dynatron A46G for my AMD X4 620 AM3 Quad Core CPU.

I thought the Dynatron A46G would be enough with passive cooling (it has no fan), but the same setup became burning hot on the underside of the server and also by touching the heatsink itself within minutes. I thought that th........
