That "losing battle against the air flow" is so real. I had a client with constant overheating issues, and it turned out their tower was shoved in a little cubby under the desk with a solid back panel. Moved it out just six inches so the back exhaust could actually breathe, and the problem vanished.

Always figured it was just old food court grease, but that makes way more sense.

That Kroil trick is a lifesaver. What's the most stubborn gun part you've ever had to deal with, even with the right stuff?

Oh man, I feel that. I started getting that weird thumb numbness while building models last year. What finally helped me was doing those wrist stretches every hour, like bending my hand back gently. I also raised my keyboard a bit so my wrists weren't bent up all the time. It took a few weeks of being really strict about it, but the tingling mostly went away. Dropping those tiny parts is the worst wake up call.

Ugh, that's just how it goes with custom builds. Honestly, spending hours on a tiny bent pin is part of the process and totally normal. You can't expect it to be easy every time.
