Well, my tower box doesn't have any special baffles (yet) but if I operate it with both side panels off and push the CPU hard it will reset, and if I check the CPU heat sink I find it unusually warm. Without the forced circulation from either the exhaust fans above and to the rear or the inlet fan that I have on my disk drives, the CPU fan appears to draw back too much of the warm air it ejects below, hence the trend toward putting a side inlet vent on the machine -- a very bad idea, since it means that you can't place the machine up against another one. (The new BTX spec addresses this, but it looks like it introduces other problems.) I suggest that Joey check the temperature of the drive as he usually runs it, then again after running with the box closed. Mark Terribile __________________________________ Do you Yahoo!? Yahoo!
