debating whether or not i want to try running my A64 X2 3800+ passively or not. using a CNPS9500 AM2, and have a Aerocool Xtreme Turbine 120mm fan in the rear of the case, and the 120mm PSU fan. was just playing HL2DM for a little while, and it appears that the highest it got was 49C. i might try again later for a bit longer of a time period, but was just wondering from that little test if it would still be fine to run passive. is there any better app to record CPU temps, and maybe even GPU temps too? i used to be able to use Motherboard monitor with my A8N-SLI Premium, and have it display the highest temp both the CPU and GPU's reached..... but don't think anybody made a plugin for it yet for NForce 500 motherboards. edit: oh..... and at idle.... there's no difference in temp whether i have the 92mm fan on the CNPS on or not. either way it idles around 30-32. right now after closing HL2DM though.... it doesn't seem to want to go lower than 35c..... but i highly doubt that even 49C is too hot for the CPU.
