Salty tears of a hot boxer.

While liquid cooling is far more efficient than passive or active air cooling, the heat still has to go somewhere. The radiator is going to slowly heat up and at the same time heat the room up. If you don't remove the heat from the room, you're going to be in the exact same situation as air cooling.

Liquid cooling doesn't magically make the heat disappear.

I'm ordering my 5x rackmount cases today. I'll get some pictures up hopefully soon about how I plan to deal with heat exhaust in my office.

Please do update your rack mount post with the cooling solution. Inquiring minds want to know!!

Maybe you can find a used Liebert unit on ebay.
