I'm setting up a new server in the rack in our closet. I started with a surplus Rackable 1U system with 2 Intel Xenon E5472 @3.0 GHz, 4GB ECC, and no disk drives. The motherboard is a Tyan Tempest i5400PW.
It had a bank of 5 24CFM fans, one of which had failed (seized-up). These fans were unacceptably loud for our office environment, so I replaced them with 5 8.5CFM and 1 5CFM fans.
I also added 28GB ECC memory and 2 1TB drives.
The system worked fine when sitting on a box in my office, but when I moved it to the rack, it ran for about 8 hours and shut down. All indications are that this is being caused by overheating, because the CPUs and BIOS have a temperature monitoring screen, which initially shows that the CPUs are running about 40° below Tmax, but after a few hours, this reading goes lower until it says N/A. If the machine is turned on within an hour after it shuts itself down, then it will only stay on for less than an hour. The air flowing out of the back of the case feels cooler than a hair dryer, but warmer than a residential heater register.
Question: Can I simply replace the CPUs with more modern (and green) models that take less power and thus will not overheat?
