I'm using an older ASUS M32 Series which is about 5 years old as a sort of server for files and printing on my home network. I took the computer apart a few weeks ago before I set it up as such, just out of curiosity to learn more about the components. I put everything back into place but I'm worried that I screwed something up with the thermal paste on the heat sink/cooling unit, above the CPU. I moved it around, taking some off, and the rest looked somewhat dried after leaving it out in the open for a while before re-assembling it.
I ask about this because I notice when my computer goes to sleep, the main circular LED light for the power on the case blinks red. When the computer is active, it's a normal white solid color there.
I tried downloading that Asus Probe II to figure out what the problem may be but it seems outdated and no longer supported, and I've had trouble doing a clean install of it. I then got into the BIOS on restart and it said the core temperature was like 109 degrees fahrenheit for the CPU, and somewhat lower for the motherboard itself. I then installed the CoreTemp program to verify this and it's giving me lower temperatures, around 30-32 celsius or in the upper 80s fahrenheit. Either way, I'm a bit worried about this.
Is it a safe bet that the problem is linked to an overheating CPU, and I should get some new paste to replace the old with?
