Recently I was able to finally build my NAS. Not knowing any better, I’ve been using the stock heatsink that came with the CPU. Every several weeks or so, I come home and the server is no longer running. At first I didn’t know what was happening, but then it started beeping while I was home. I looked up the error code and found the CPU was overheating. When I opened it up, I found the heatsink was a little loose. I haven’t assembled a computer in about two decades. I assumed I hadn’t mounted it correctly. I made sure that all four pins were clicked all the way in, but yesterday the server was powered down when I got home from work. I assumed the heatsink was loose again, but when I checked it, it was tight and secure.
Here are the specs for the server:
Motherboard: SUPERMICRO MBD-X11SSM-F-O Micro ATX LGA 1151 Intel C236
CPU: Intel Xeon E3-1225 V6
RAM: Crucial 16GB DDR4 SDRAM ECC Unbuffered DDR4 2666 (PC4 21300) Server Memory CT16G4WFD8266
I’m running the latest stable version of FreeNAS with only two jails (Plex and Nextcloud). I am happy to provide other details if needed. I’m not overclocking the server, and I barely put any load on it at all. I’d really like to get to the bottom of this shutdown issue so I can have a reliable server. Does anybody have a suggestion?
