Those seeking information on repairing a PSU's internal components are at this stage:
If they had more knowledge, they would have simply
done it, or understood enough to
avoid doing it.

I've experienced it before. When I was ten, I inserted both fingers into an open lamp socket after taking out the bulb. After getting a 240V AC shock, I never did it again.
This was one of several times I suffered from electric shocks. In the 1960s, there were no ways to reduce the risk once you opened the appliance cover.
A friend injured himself by sticking a knife into a vacuum cleaner motor; he lost an eye but still got his private pilot license and flew over the Everglades before the first Space Shuttle launch.
At work, I was taught to identify Safety Critical components in the mains power supplies I developed.

Back here once more, still not had time to fix the Windows yet. I think I’ll tackle it this evening.
I was wondering if I’m planning to do something wrong, not about the method itself. That’s a big difference.
Thanks for the tips and trust. But I’ve decided not to fix the fan after all. Instead, I’ll just endure the noise and save money for a new PC (even though the fan was fine, the PC is still getting pretty old and outdated). I’m just curious—could it really be possible that after draining those big capacitors (using the method you and I discussed), they might still deliver a strong impact?

I'm really concerned but it looks like I've broken an unlisted rule about this forum—no assistance should be given to anyone planning to work with dangerous voltages or trying repairs. The risks are too great. If you need support, it's clear you lack the necessary expertise. Catch 22.

As a result, I can't provide further guidance on this topic. You might want to think about taking an electronics engineering course at a college or university instead. A simpler alternative is to simply stop working on it and purchase a new computer. Good luck.

I don’t fully grasp this rule. Isn’t it better to warn someone about a potentially dangerous action so the risks are reduced rather than allowing people to try these kinds of stunts alone?
If I were as stubborn as I am, saying “don’t do it” would be more helpful than nothing. If someone had explained how to do it correctly and listed possible failures, I’d then weigh whether the risks are worth taking and if I could remove those dangers.
But I think it’s a double-edged sword, and in some situations providing full tutorials could actually cause serious harm.
