So... i buy a new gpu, it's fan is very loud, ->i get the latests catalys drivers, i monitor temp and fan speed with riva, i see that it goes to 5%, but it's still verry loud and the temp stays very low (37 degrees). So i change some settings with riva, including duty cycle min=1. The volume goes down a bit but not enough,and now on idle it stays on 1% 39 degres C, and in games at 2% fan duty cycle and 50 degrees. I can't get a monitor on fan speed though. Yet still, the fan is too loud in idle, and is driving me crazy, and the 40C temp just proves that it is spinning too fast. changing fan duty cycle one 100% one way or another doesn't help, 1% fan speed remains 1% fan speed. I'm looking towards 2 solutions: 1: the most indicated and good one would be to slow the fan speed even more but not stop it. I believe that somehow 1% isn't exactly 1% when it comes to this fan. 2: If 1 fails, then the only solution would be to stop the fan when under 50c.(If anyone can point me to/do a guide on how to do this i would appreciate it and i will not become insane because of my fan noise and i will be a better person) screenshot of the monitorig, notice the 1% duty cycle. and this is my gpualit HD 4850. notice the fan... http://ncix.com/products/index.php?sku=30981&vpn=XAE/48500+T352&manufacture=Palit Multimedia Inc. ps:don't buy this card with this fan. you might one consider something like this insteadsame card, diferent fan) http://www.bit-tech.net/hardware/graphics/2008/10/14/palit-xpertvision-radeon-hd-4850-sonic/1 too late for me though :/ so.. any ideas on how to get below 1%?
