I may need to clarify what kind of "water cooler compressor" I'm talking about. The kind you put 5 gallon jugs in so employees have an excuse for not working.
I purchased one for under $80.00 and I can't stop thinking about converting the compressor to cool a processor.
If you make the leap to fluid cooling, you don't need a compressor. A simple pump, radiator and fan will dissipate more heat then your PC could ever produce.
