With the copper version of both the Zalman CPU and AGP coolers, running a Sempron 3000+ with and ATI 9800 Pro. In a Thermaltake Tsunami case fitted with a 350 Watt PS and no extra fans apart fron the one on the AGP cooler. I get an idle temperature of (CPU) 35 - 35.50c and (AGP) of 32c. After running GW SHIII for a couple of hours it goes up to 37.50 - 38c. With the 'auto-overclocking' facility in the Omega drivers during the game.
Just the normal radiator central heating in the room, so it's not a cold place generaly. But anyway, Zalman coolers or a water cooling system are worth the investment especialy if you are clocking even moderately.
Just as an off topic mention, I found out this evening, at the start of my ninth patrol. That you can still use the 'free view', the eye thing, whilst the game is paused. It certaily might be interesting to use during attacks etc, but on the way out of St Nazaire I was able to pop up and get some still views of the Messerschmitts flying over, and of the seaguls:sunny:

Hi Deepsix, I have an X700 AGP card & it weighs 1kg (no kidding) but it runs cool, I purchased 8 small (video card) copper heatsinks, come with adhesive thermal tape & cost around AU$15, I also placed a vantec iceberg cooling fan on the opposite side of the other fan (now has 2) since it had a nice flat piece of aluminium plate to mount to!:up: Yes I'm a little paranoid about heat problems.:huh:
Also I have an AMD Athlon 64 processor & can vouch for a fact that the Vapochill (refrigerated) heatsink keeps the processor at around 28Deg C without giving off much heat at all, and it cost around AU$70 I previously had a radiator & pump setup, and this is better!!:D
Hope this is of some value to you!
Cheers.
