Isn’t the risk of damage with liquid metal too high? Why not just run the CPU without the lid?

Most likely you have some bad caps. However, my Operton 185 also stopped working pretty quickly due to the old thermal paste under the lid.

I didn't understand if the liquid metal can damage the lid or not, if not and it's properly applied I doubt it can damage anything.
Bad caps on the legendary dfi lanparty ut nf4 ultra-d? I hope not 😁

I needed to recap my socket 939 motherboard to improve stability.

As I understand it, liquid metal is electrically conductive. When the heat spreader is placed back on, the liquid metal
can get pressed out and into one of the numerous capacitor networks, thereby shorting out the CPU.

It is also very easy to have the heat spreader short on these capacitor leads. There’s only about 1 mm of clearance.

If you insist on placing the heat spreader back on (which I see no need for), please photograph and document your work here.

Honestrly I am even unsure if I will be able to delidd it without killing the cpu.
I ordered the razor blades but I will try to delidd a cheap 939 cpu first.

I don't see how you can kill the CPU. All you can do is ruin a few capacitors.

Did you run the cheap 939 in your system to ensure that there's no other issues with your motherboard or heatsink?
