Hello,
So I've recently revived an older Dell DCS 6005 server as a temporary hold in for a failed NAS, until we can budget for a proper NAS.
In the interim, I've modified the chassis, took out 1 whole sled, cut the Top lid to accept 1 140MM Noctua ippc-3000 fan pointed down at each sled, and then removed the stock chassis fans that are rediculously loud, and replaced one 80mm fan on each sled pointed to the back, to create a front-to-back pressure direction. With this setup, my CPU's are in the ~30-35'c range, and the chipset float around ~40'c range under test load.
One of the issues that I'd like to solve is that the 80mm fans run at 2200rpm, which is above the min amount needed so that the BCM threshold alarm isn't triggered. Except that I only have two fans. Is it possible (or safe'ish) to splice the fans speed sensor wire into the un-used fan header sensor, so that the BMC thinks all 4 fans are running at the same speed ?
