Maybe it's just something that I'm doing wrong, but I get pretty damned high temparatures for a 1GHz/266FSB Athlon mildly overclocked to 1072MHz. My mobo is the Asus ATV133. I'm using the retail heatsink/fan combination with an Enlight 7237 case. I have one fan blowing out. I have tried leaving my case open, moving around cables to improve airflow, changing my voltage, etc. My room is pretty hot, but my case temp never goes about 40c. However, my CPU temp has gone as high as 70c. Does this heatsink/fan combination just really suck or what? I am getting some new equipment for my case, 2 80mm fans (One faster than my current one to replace it), and PCI slot fan, and an OCZ Gladiator w/36CFM fan. Some AS2 as well. I was just wondering if someone might think I have done something wrong here? I just don't want to do it wrong again when I get my new equipment. I'm pretty sure I didn't, because this is not the first system I have built. However, I just want to double check. Thanks.
