This may be off topic from vista but I was just wandering. What temps should I look at? Rite now core0 is at 53C and core1 is at 55C. My office has no cooling or insulation so it can get hot in here. The other day the temps hit 62C and my fans fired up for the first time in the 2 years sence I got the computer. It worried me because all of the sudden there was all this noise like a jet under my desk. When I investigated I noticed the fans went from about 1500rpm to 4500rpm. As soon as I dropped below 60C they went right back to 1500rpm. I have been told I dont want to go above 60C is that true? I have the PS fan, stock case fan in the front and a CPU fan. I added a fan to me 2nd HD as well as one of those blue led fans that hook to one of the card slots. I think though the led fan is sucking air in from the slot and blowing it down on the CPU and I am pretty sure I was told all the air should come in from the front and exit the back so basicaly I am sucking hot air from the PS right in on the CPU. Hmmmm any suggestions? Should I remove the 2 fans I put in there and just let it run with the fans that came with the system?
