how do i cool a 1U server CPU?

post #1 of 5
Thread Starter 
To make a long story short.

-1U chassis
-95watt socket 1155 CPU

how do i cool this?

I've been looking around online, so far the highest I've found is a 73watt heat sink.

:::EDIT:::
am i even posting in the right section?

Is it 73W of passive cooling? If you install a blower you'd increase it's ability to dissipate the power.

Servers that small are made to be tiny wind tunnels. You should have a boat load of puny 2000+ rpm fans that will bring in air, and blow it front to back. They usually are the only fans in there, and will do the work of making sure enough air gets back to your CPU passive heatsink.

Easy, ya cool it with a 1U fan!

I don't know if you have ever seen the inside of a real 1U server, but there are numerous plastic channels, and 40mm fans blowing air from front to back. Noise is not a concern since they are in a noisy datacenter, so 1U servers should be avoided for home use unless you can secure some small and quiet fans (which isn't too likely).

Your best bet might be a compact blower type fan like you would see on a graphics card. You can hunt around electronics/surplus industrial component sites to find them. You might have to do some custom wiring for the tails to give the fan 12v, 7v, or maybe 5v, but it is a nice and easy project for a modding beginner.

like in this case, the cpus have passive heatsinks and the fans either pull air from the front vents over the heat sinks or push it from front to back and me looking the pic cant think atm by looking at the fans which way the air goes.. im not sure yet as the server is stitting at customs but it gives you an idea how they are cooled.. this might be a 2U unit but the basic principle is the same as for 1U andf you would have 1U fans in some sort of configuration and tunneling as others have mentioned...
