Well, first, all my servers have dual PIII CPU, if that matters. Second, i have a 4U rackmount chassis with 1x 12CM in front ( on the side) blowing in, 2x 8CM blowing out in the back and of course PS fan also blowing out. The CPU fans (retail intel, btw) are running too. My CPU temps go as high as CPU1 43C CPU2 48C . Can you guys provide readings of your CPU temps in such boxes as mine so I could compare them. My current temps CPU1/2: 38C/41.5C Thanks, Simon On Tue, 27 Mar 2001 02:20:10 -0500, Mike Nowlin wrote: >> As a rule, do put AS MANY extra fan in a PC box as possible. > >Agreed, but it's important to make sure you have the right balance of fans >blowing in vs. blowing out.
