However, when I put a fan on them, no reboots, whereas before I could crash the machine with nasty memory corruption after about 1 hour of sustained > 100Mbps bi-directional traffic. The temp probe I used showed them to be at about their operating max, though I forget what that was now... Maybe your chipset or cooling is better and you won't hit it..but if you do see crashes, try a fan :) Ben > > -Ralph > -- Ben Greear President of Candela Technologies Inc http://www.candelatech.com ScryMUD: http://scry.wanfear.com http://scry.wanfear.com/~greear
