Greetings. VERY Long time lurker here, but I've finally got a question that has me stumped.
I have an old computer (pentium D from 2005) that I run 24/7 as a dedicated all sky camera recorder that has recently experienced a few shutdowns from high CPU temp
. Ironic thing is it's sitting out in my metal storage shed where temps have been averaging +5 to +10 F for the past couple of months! I need to wear arctic gear to go out and reset it when it shuts down!
Before being turned into a full time dvr, this computer ran fine 24/7 for years, even back in my hot, non-air conditioned room in SoCal. It uses your standard heat pipe and fan CPU cooler - actually a fairly good sized one at that - it's a Sony Vaio.
So it got me thinking. Is it actually possible that the fluid inside of the heat pipes is freezing at these low ambient temps, and thus cutting off all
heat exchange from the CPU? It's about the only explanation I can come up with. In this application, would it just be better to go with a standard, plane-Jane aluminum fin OEM cooler?
Anyone else have experience in low temp environments like this?
BTW, if you would like to see the camera feed:
