Summary: I simply replaced the stock coolers with copper-finned heatsinks, and rigged up a cooler with two 120mm high-cfm fans to blow directly on the heatsinks. Works like a charm! I have been using two of these for 6 months.
Pros: Look at the benchmarks. Running two of these puts you among the top-performing personal computers available.
Cons: Stock coolers are loud, and don't cool as well as they should.
Summary: I'm an AMD fan boy and this is my first Intel processor ever since Athlon XP hit the market. I had no choice but to buy Intel when AMD failed to deliver their quad core on time. I'm quite happy with the purchase, but it doesn't take away the guilty feeling at all. Anyway...
Pros: Runs fast and great. Handles load extremely well. I run 15 virtual machine on a single proc server, and it doesn't even even hit the 50% load while I'm completely out of my 16GB memory.
Cons: Pricy, but I suppose you get what you pay for. Low memory bandwidth for such processor comparing to AMD counterparts, even a low end 2246HE I'm running my Debian server on.
Summary: The CPU comes with an active fan, to be connected to motherboard using 4 pin cable. while all available sockets are used on the motherboard. I have failed to find a right cable: ether a Y 4 pin fan cable or a special cable connecting directly to power.
Summary: If you choose to use 64 bit Linux or BSD OS it can be a bit of a pain to get everything installed and compiled correctly. Most apps' 64 bit support isn't as good as 32 bit although eventually everything we use worked. VMWare Server has to run in 32 bit which was a pain to figure out.
Pros: Great performance. Handles extremely high loads without getting bogged down. Has worked great powering several servers we are running in VMWare.
Cons: Runs pretty hot under max load. The heatsink/fan it comes with are not good enough. Get a good PSU of at least 1000 watts. A couple of these, RAID array, and all the fans you need are power hungry.
