Does anyone else have one of these systems? I've got it using the stock cooling the radiator which is mounted on top of a 2500+, and I'm seeing temps around 48C/118F, which seems fairly high for what supposedly was supposed to cool better than a plain AMD fan. When I went to pick up another tube of Arctic Silver, I was told that the particular store didn't carry it because it "wasn't any good, and we don't sell anything that's not good" but that's beside the point. Anyhow, I'm using Antec Thermal Grease at the moment, and I have a feeling that this is the cause of my problems. Any thoughts? On a side, note, this is a pretty cool little system. I've sold about 5 of them to coworkers as I was building it over the course of the day $500 for a complete system, $650 for the system + a 19" flat screen CRT. Not too shabby.
