Personal opinion follows. :) If it is a heat problem there are a couple of possibilities. First no matter how big the fan/heatsink is it won't work as well as it can if you don't have a thin layer of thermal grease between it and the processor. Some fans have thermal tape ( Intel boxed Celerons ) which is pretty much equivalent. You might also want to check that there aren't any drive cables obstructing the airflow into or out of the fan/heatsink. Next, the fan on the CPU can only cool the processor down relative to the air temperature in the rest of the case so keeping the case cool is very important. This doesn't mean you should leave the case open. I have a machine here with 4 full height scsi drives that flakes out after just a few minutes with the case off since the drives overheat. If it is an ATX case/power supply make sure it is not one of the older ones that have the fan blowing IN rather than OUT. Most cases allow you to add a fan at the bottom up front to bring more air into the case and larger cases have a spot for a outgoing fan above or near the power supply. You probobly want to make sure you have a bit more fan taking the hot air out the top than is bringing air in the bottom. I have never used a slot fan but suppose it is a good solution if your case doesn't have room for additional normal fans or you have card with a heat problem. You also want too check your CPU voltages. I believe the AMD 450 and SOME of the 400s run at a different voltage than the slower K6 chips. -- ------------------------------------------------------------ Christopher Weimann SysAdmin 400 Higgins Ave Wall Internet LLC.
