My computer is shutting down(says it's overheating, cpu cold

Whenever I start my computer, I go to my Bios and it says my cpu is rapidly heating up, 49C to 70C in about 5 seconds. It auto shuts down since it gets to 70C, I go to feel the conductive pipes my heat sink has, and it's cold. It has only recently done this when it was overheating legitimately, and I replaced 3 fans I had in the system that broke. I can't even get to the desktop before it shuts down.

Good find!

If the pipes don't warm up that's a sign that contact from CPU to the heatsink system may be non-existant. The CPU would heat up, but not the pipes.

ive had this cooler for a while, pretty secured over the CPU

In reply to: Good find!

As the title says, I can always tell if the CPU is hot or cold by touching this, and usually it's hot when running for a while. So I know it's connected well

Try another CPU.

pipes?

"the conductive pipes my heat sink has, and it's cold."

Obviously a liquid filled, or once was liquid filled heat sink. Maybe liquid is gone? Or as Bob suggested, new thermal paste is needed. No doubt that the CPU is overheating, so that's HSF time.

Damage done...

In reply to: My computer is shutting down(says it's overheating, cpu cold

I read the other posts and you say, 3yrs. old, it maybe time. Further, you stated 3-fans replaced. Well, all this suggests thew damage is already done. The cpu cooling was compromised. You should repaste the cpu goop or replace. Make darn sure it does attach to cpu, because it can gap if it has gotten too hot. The fans alone going bad overtime and not replaced until too late the cpu itself is damaged and it's build-in sensor is too keen and trips. As stated try another cpu. Invest to make the new cpu and its cooling apparatus setup is 100%. That's not to say if any mtrbd. sensors are present, they too could cause issue and being the mtrbd. based ones, that requires a new mtrbd. Of course, you find what works for you and proceed to resolve it. the point being it may not be so easy, until the repair encompasses all aspects of operation. good luck

FYI- You provided no full details of your PC, it does help.
