Overheating Automatic Shutdown?
I have a question about overheating. I am thinking about running blender on this machine so it will be working sometimes 24/7. I want to make sure that my cooling is up to snuff. Before I go spending money I want to make sure I really *need* any of this stuff. So, I have a few questions.
1. Don't cpus automatically shut themselves down if they overheat? (ie anything newer than a pentium.) 2. What about video cards? Will they shutdown automatically? I don't really care if I wake up to find my computer shutdown, what is more a priority is that my hardware is safe. |
Modern, new, and good CPUs and GPUs will THROTTLE themselves down if they start overheating. It's different from shutting themselves down, they simply underclock themselves so that they don't overheat.
Whether they will shut themselves down in the case of a sudden, catastrophic loss of cooling, say the heatsink falls off completely, that is a different matter and is up to much debate. I know for a while Intel bragged about its CPUs being able to shut down before meltdown occurs, i.e. the CPU melts and damages the mobo. AMD on the other hand was said to have an inferior method of such shutdown, where there was a chance it could overheat before power was cut to the CPU. This was quite a while ago tho, and the article was clearly biased towards Intel, so I can't be sure if this info is relevant. Either way, let's assume you don't ever want to put the CPU or GPU in such a position. Many BIOSes have the ability to warn the OS via MCE, in the kernel it is: Code:
┌──────────────────────── Machine Check Exception ────────────────────────┐ I say if you get a good, reliable CPU fan, and clean the dust out once in a while, there shouldn't be any problems. Make sure you have plenty of other fans on the case too, and they serve some purpose in cooling. Oh, and use good thermal paste, and only a small amount, just enough to cover the base of the heat sink. |
GKrellM (and probably equivalent solutions) can be configured to run a script when settable limits (temperature, fan speed, ...) are passed; that gives a wide range of possibilities! :)
