Thomas, Don't forget your Arctic Silver 3 thermal compound. You need that. It has the best heat transfer rating of any of the others. For thermal resistance test results on some Volcano 9 and 7+ vs the VA4-C7040's, please see the following: http://www6.tomshardware.com/cpu/20030113/cooler5-39.html#hot_or_cold_thermal_resistance_is_decisive Yes, the Va4-C7040 beat those Volcano's in this roundup. The noise levels *could* be made to be comparable, but he had to reduce the rpm's of the volcano's down to 1800 in order to achieve that. Meanwhile the VA4-C7040's were running at full speed for the noise level tests you see. > > Thomas, > > Not a hazard due to db level, but it can affect your hearing in that > the the air in the room pulses rhythmically.

On a side note: While doing some overclocking tests I noticed that under full CPU load the mobo sensor was reporting 59C. This naturally bothered me quite a bit. I checked inside the case. Guess what? A SCSI cable was hanging over the HSF with only about a quarter inch clearance or so. About half the fan was covered. So I rerouted the cable, and the temp dropped under full load a full 5C; down to 54C. I think I'm going to refit the whole machine with round IDE and SCSI cables. --LX P.S.
