There I was, working away on my computer, Predator 2, the one I'm on right now, and it suddenly turned off. I thought there might have been a brief power outage, so I powered it back on. Thirty seconds later it turned off again, then again, and again. After opening up the case to look for a mechanical problem such as a dead cooling fan, I discovered the heat sink/fan bracket for one of my CPUs had snapped, allowing the heat sink and fan unit to come away from the CPU. I was able to lay the computer on its side then pressed the heat sink against the CPU. The thermal grease between the CPU and heat sink held. I was able to power up the computer and everything was working fine, except that if I stand the computer back up into its vertical position, the bond won't hold- the heat sink will come away and the computer will power down. my computer is thirteen or fourteen years old. I can't find a replacement bracket for it. Today I'm going to build a new bracket in my other computer, Predator 3, then 3D print it. I hope this works. I built Predator 2 as a server with two dual core processes. In it's day it was a very powerful computer. Today, it still runs most newer software but, by today's standards, it's abilities are only average. Still, it's a great computer capable of running 4K video, editing, sound processing and the rest, but it's not a computer powerful enough to render advanced CGI renderings. I'm going to power down now to remove the damaged bracket so I can begin building a new one. I'll post pictures later.
