Question PC shuts off after 20 seconds

[Joojnini]

Hey guys, I was building a new pc using my friends old NZXT Kraken 240 (1y 6m old) since he wasn't using it anymore. Unfortunately it just didn't work, I can maybe try to fix it later but the AIO seemingly wasn't doing its job. At the end of the day though since I got it for free I'm not too worried about it lol.

My Ryzen 7 9700X temps were around 75+ C while idling which doesn't seem right to me. Correct me if I am wrong though. Reapplying the paste did not fix the issue. But anyways, I removed the AIO to prep the build for my new Noctua CPU cooler to come in the mail, and I just gave it a quick boot to see if everything is still in working order. After about 20 seconds or so, while windows was opening, the pc would just suddenly shut off from what I could only guess was the pc protecting the CPU from overheating? There is literally nothing cooling the CPU at the moment. I turned on the pc again once more while trying to go into BIOS and the same thing happened, I haven't turned it on since.

I'm just wondering if this behavior is normal, or is it something I should be concerned about. I guess the only way for me to truly know if something is up is when I install the new CPU cooler and the same thing is happening, but any feedback would be really appreciated. Thanks

CPU: Ryzen 7 9700X
GPU: MSI Gaming TRIO 5070 Ti
Motherboard: X870I AORUS PRO ICE
PSU: Corsair SF750

Welcome to the forums, newcomer!

There is literally nothing cooling the CPU at the moment.
If you want to ruin your processor, multiple attempts without a cooler could help you accomplish that. That being said, since Noctua's non-redux range coolers(as the redux comes with thermal paste preapplied on the cooler's base)come with a tube of thermal paste, you should rest the cooler on the CPU's IHS and fire it up.

I'm just wondering if this behavior is normal, or is it something I should be concerned about.
It's protecting itself form damage from heat, since you state not having any cooling on the processor.

Make and model of your case?

Hey there, thanks for the reply! Yes, it is rather unwise to boot the pc up without a CPU cooler installed, but I have quickly learned my lesson, lol. I actually have a tube of NT-H2 thermal paste from Noctua currently, I swiped an extra one from my aforementioned buddy. My case is the Ncased M2, I'm building an SFF build right now. The CPU cooler I bought from Noctua is the NH-D12L, which is a low height dual tower cooler which is perfect for my SFF build, at least to my knowledge.
