Where did you get your new machine from?
Have you got a link at all please?

Liquid cooling is a great idea for a powerful computer that will be running intensively.

What was your computer? 😳
CPUs are supposed to have thermal protection.
They should, in theory, throttle down when overheating, shutting down as a last resort.
I can't imagine software such as PixInsight can lead to such damage.
Was your CPU overclocked, or did you have an insane amount of dust inside the case?

Actually I'm having a strange issue with WBPP which might be related to CPU load. I'm not doing many batches one after the other, but the batches I do are still quite a challenge: each sub is 205 Mb (it's a huge sensor chip) and, with master flats darks etc all pre-made, it still takes a long time to process. My last run with 63 frames took 3h 41m.
And I get horizontal black lines of about 20 pixels height on a few of the registered subs (which don't appear if I do them individually). This is still under investigation on the PI forum, but may be related to processor load.
My processor isn't exactly sluggish: its and Apple Silicon M1Max and scores well on the PI benchmark.

I have a very similar setup with the exception mind is the Ryzen 9, 128gb ram as well as 3060x GPU, I also have water cooling on mine. You should be very happy with your setup!
I’m sorry you cooked your computer but in the end you got a very capable setup now that you don’t have to worry about!
Congrats on your new computer!

I was not doubtful; these things can obviously happen, especially with Intel-like architectures, as they are so bad at thermal efficiency.
I was just surprised it could happen using PixInsight on a non-overclocked CPU without a defect of some kind.
A CPU should start throttling down way before hitting 100°.
In my experience, I used computers for years with repeated hours-long compilations without any issue, with the CPU hitting almost 100° every time.
They were at about 75° with absolutely no load. This is usually not an issue; unfortunately, it can be pretty standard on some Intel chips.
So, I was just wondering if your PC had some specific defect that could have led to the problem you experienced.
If some ports on your motherboard are damaged, it's most likely scrapped. But if the PC still boots, the CPU should be OK.
The higher-than-normal temperature probably indicates that the extensive usage caused some issues with the thermal paste.
However, reapplying fresh paste should eliminate the issue.
Anyway, congrats on your new PC; this is a good setup!

i think in the PI forum it was discovered that some motherboards have default BIOS settings that are far too aggressive and set up the CPU to be able to overheat and be overclocked for too long under load. i can't remember the exact manufacturer or what generation CPU we're talking about here. but i guess the point is that a lot of the thermal throttling parameters are under control of the BIOS and as such could be misconfigured by the manufacturer that is trying to give you "extreme" performance by default.
