PC shuts down after a few seconds after removing CPU-cooler

[aexel05]

Hello,

I just tried to swap the boxed cooler of my R5 3600 with an aftermarket-cooler.

Removed power from Fans (incl. CPU-Cooler) ran cinebench for a few seconds until the CPU temps reached about 85°, turned off PC and removed the CPU cooler without any problems.

For some reason I unlatched the CPU too and took it out of the socket. While cleaning off the termal paste I got some of it on the side of the CPU and on some pins. 

Cleaned it with alcohol and then I tried whether everything still works, because I thought I could have gotten some paste on the pins or socket.

PC started, windows "loading circle" appeared and then an automatic repair started. 

 

At this point I thought that this proves that everything is working but then the PC shut off by itself. 

In my opinion it's wheter the now maybe somehow broken CPU-MB-combo or thermals.

 

Could this behaviour be caused by not using a cooler while testing or could there something else be broken?

 

What should I do next, attach the new cooler without paste and try to start the PC?

 

I think windows starting and attempting to repair should be a good sign, right?

Thank you for your help and excuse my english, I'm writing this in a rush.

So... you literally removed your cooler while your CPU was running Cinebench (probably the highest load it has ever and will ever be under)? Yeah, it definitely would have shut down to prevent damage (although it could have still been a bit damaged). You definitely screwed up your CPU, but it's hard to tell whether it was because of the paste or because of the overheating. Sadly there's not much you can do unless you or a friend has another CPU or board to test with.

No no no. I ran cinebench too warm up the thermal paste, shut down the PC myself after a few seconds and then properly removed the CPU cooler. Only the CPU-cooler fan was removed while running

I could have overseen some thermalpaste on an pin or maybe some even got into the socket. That might be the problem.

Windows started and tried a recovery, so to some degree the CPU definitely works.

Correct me if I'm wrong, but are you complaining that the PC shuts down when using it without a CPU cooler? because thats what its supposed to do to prevent damage.

Even if a little bit of thermal paste would get into the socket, it's normally not conductive and as long as you let the alcohol completely dry out before reinstalling your CPU i don't think your motherboard or CPU is damaged. Unless you dropped any of them that is.

 

Just remount everything over again and try to boot again.

OP accidentally got some thermal compound on the pins and cleaned it off. Then OP wanted to see if the PC would boot, so reinstalled the CPU without the cooler to check. Then the PC shutdown while booting.

 

Compounding mistakes.

 

Take a deep breath, OP. It's gonna be fine.

 

Don't remove the CPU before cleaning it. And never boot a PC when the CPU has no cooler on it. Even just placing the cooler on the CPU without compound and without securing it would have been enough for the test you were trying to do, and you could still do that now to see that things are working.

Yeah basicly thats what I'm asking.  Does tempeature build up so fast, that it is supposed to shut down immediately? 

 

I dont want to completely attach the new cooler+thermalpaste only to find out, that it doesn't work.

Would only Cooler+Fan be appropiate for just trying whether the PC boots into windows?

Yeah you got it. 
Dont know why I removed the CPU from the socket too. I was just acting and not thinking...

Okay so I can do my short testing with only the headsink of the old stock-cooler attached?

Yes it does. You might be fine going into BIOS for a short time, but trying to load Windows put more load on the CPU than the heat spreader alone can deal with.

 

But as @HairlessMonkeyBoysaid, butting the cooler on without paste should let you do some basic stuff.

Yes, do make sure it has at least a little bit of thermal compound.
You should be able to feel the cooler warm up.

And depending on your type of CPU yes that can be instantly after boot and a lot too.

Just happy current CPU's have all sorts of safety's, so most likely the CPU will be fine.

Just take your time, and dont try any shortcuts, and those will lead in destruction.

Yeah. You can attach the stock cooler without thermal compound and without securing it. Just let gravity keep it on. I've done this before. That will be enough for a quick "peace of mind" boot. Just don't put it under any significant load.

Luckily it worked. Windows tried to repair itself, skiped that, logged into windows and then shut down again.
Everything seems to work properly.

Now I'm optimistic enough to replace the cooler with the new one.

 

I'll post an update if I'm successfull.. or somehow manage to turn my Ryzen into a Pentium while doing so;)

Thank you for your affirmation, didnt want to cause more harm.

To put an end to this saga:

I managed to successfully swap the Cooler.

Works fine and as intended.

 

Thank you for your help
