I built my own rig (check my sig for details) and the dang thing is just WAY too loud. I would like to change my cooling to something a bit quieter. I would like to get a liquid cooling system if possible, but I would rather not spend more that $100. If I were to go with a liquid cooling system, my biggest concern would be the CPU, not a full system. Really price and noise level are my two biggest constraints. Any suggestions?
