One of my older systems is an older Pentium 4 1.8 in an Intel D850GB motherboard. I originally had 2 sticks of 256MB PC800 RAMBUS in the system, and it ran just fine. I recently added another 2 sticks of the same kind of RAM into the system, and since then I have been getting overheat alarms from Intel's Active Monitor (System Zone 2 gets up to about 125 degrees F). I was wondering if anyone had any tips on how I can keep this system cool. I have 1 case fan up front, and 2 in the back, and still the only way I can run the system without getting that alarm, is when I use it with the case off. Even then, it still overheats once in awhile, and I blow a big box fan on it, that brings it back down to about 105. I was considering buying a new case, but wanted to see if you guys had any suggestions before I did that.
