Don't get confused by the ugly look of the server rack and the case server itself is mounted in, it's a perfectly working cooling machine ..:)
First of all the rack is located in a basement which is not air-conditioned but temperatures rarely reach over 20C. Server case is open (= best for cooling) and the server rack has 2 large holes one sucks cold air at the bottom and the other one let's the warm air out on top so it works like a chimney.
Second - the Zalman CPU cooler is one of best air-cooling solutions on the market. The CPU even @4,5GHz maxed at 55C after an hour of hardcore stress testing.
Third - the CPU is a perfect overclocker (it ran even at 4,7GHz), but I have to agree that there's a major difference between a rig on your table and 24/7 game server. I raised it from 4,2GHz up to 4,5GHz because I finally replaced the temporary memory sticks with the 1150MHz ones and I still thought we can run stable on higher frequency. 2 hour stress testing (which I have done during last name changes) was okay, but nothing can make you sure better than real-time load caused by real applications. So there we are, running stable (I hope) at 4,05 GHz.
But remember, there may still be crashes caused by bugs, cheaters and corrupted files, we can never 100% prevent all the crashes, sad but true.
