http://www.zalman.co.kr/english/product/cnps3100GP.htmI put one of these on a computer I built for my daughters a couple of days ago. Its wild looking but it works by total simplicity. Instead of small heat sink with a fan on top screaming at 7200 rpm this works with a large flower/fan shaped HS and a large 90mm fan turning slowwwwly up above it. In fact the bracket for the fan is held by three screws over on your PCI slots. The one I bought isn't Gold plated but is pure copper,pretty far out looking to say the least,and its heavy,this ain't no cheapo HS.The one I bought has a rpm speed control. You can lower the speed as low as about 1350 rpm,high speed is only about 2500. There is so much heat disappation through the big HS that you can most likely run inbetween the high and low rpm. It keeps the CPU as cool on my daughters system as the screaming Coolermaster Heat Pipe setup that I have on my system. I've seen this same fan with a different name at places like CompUSA but you can save a few bucks over at NewEgg.David

David, Sounds interesting. Did you take any temp readings between the old and new? Also do you have any other cooling fans in the case?Terry

>David,>> Sounds interesting. Did you take any temp readings between>the old and new?

But...it was basically the same specs of a computer I built for myself about 15 months ago. ASUS A7V266-E mobo,XP2000,Antec case. The Zalman keeps the temps about the same as the Coolermaster Heat Pipe HSF that I have in mine--except the noise level on the Zalman is very,very low. I also have a front and rear fan-80mm in size and used Artic Silver3 on the die. The clip is a bit tricky to get on but not impossible. All in all its a great HS and fan for the money IMO.David

Thanks DaveSounds great.Terry
