Hello, I've just added a second hard drive and a GeForce4 Ti4400 to my computer, and I have a question about acceptable temperatures for my system. (I posted before in another thread, but now that things have changed, I just wanted to make sure.) My system is as follows: AMD Athlon XP 1600+ (non OC'd) ECS mobo 512MB DDR GeForce4 Ti4400 (non OC'd) Maxtor 7200RPM ata133 Maxtor 5400RPM ata100 300W Power Supply I have one rear fan blowing air out, and just added a front fan blowing air in (not sure how much it's working though, as there isn't much air hole space in the front pannel...but I can feel that it's bringing in some air) And the usual power supply fan blowing out air. Anyways, here are what my temps are: At system idle - CPU 46C, Case 28C At full load - unknown -- I can only use the temp setting in my BIOS since Motherboard Monitor doesn't work my my motherboard. There is something that I'm quite confused about here though. Before added the new videocard and hard drive my temps were 40C/27C. How would adding a videocard and hard drive make my CPU temp go up by 6 degree's, and my case only 1? I would think it would be the other way around. One last thing. The fan on my CPU...It's blowing air onto the heat sink. Is this correct, or should it be blowing air off of the heat sink. Thanks so very much for any suggestions you can give.
