Hay folks, I recently built a new PC for my recording studio. I am using an ASUS P4P800-E DELUXE mobo with a Pentium 4 3.4g Prescott processor oc to 3.8. The machine is used with an application that requires intensive CPU utilization (real time data acquisition, FFT, CCR). The Mobo comes with a monitoring utility and the temperature of the cpu usually sits around 56c which is right at the upper limit. I am currently using the stock heat sink from Intel. I did a little browsing over at newegg and their are a large variety of options. I have some limitations in terms of space, some of the heat sink designs with large diameter will not fit into my system. I was considering a liquid cooling system. I have read mixed reviews on performance. Does any body have any suggestions or experience with liquid cooled systems?
