Let's see... I bought my 480W Coolmax Taurus about 4 months ago (close to when this thread was started, I see). I run [email protected]
close to 24/7 on an A64 +3200 with a Zalman 7000Cu. It rarely gets hot to the touch (it's bearable for about 3 seconds when pressing your fingers against it), but only under load when the room temp is high or the side panel is on and even then, it's only sometimes. Yes, I leave the side panel of this comp. off because I don't feel like modding my cheapo case (haven't made up my mind what case I want to buy). With the panel off, under load, and the two 11 dBa 80mm SilenX fans blowing across the graphics card, CPU HSF, and bottom of the PSU, I get a stable 48ºC CPU & 43ºC sys temp. Keep in mind that I live in central Florida and it's summer. The last PSU I had in this case was an Antec TrueBlue 480W, and the temp increase from that was maybe 3ºC on both temps. With the side panel on under load, the CPU temp levels off at about 54ºC (not terrible, but I want it under 50ºC).
Overall, I'm very pleased... though I was a bit nervous initially after reading SPCR's review of this PSU. I'd recommend this PSU to anybody. It's ~$60 less than the Antec Phantom (I bought mine for $110 via Pricewatch.com) and it hasn't let me down once.
