Owterspace Doing it manually is becoming a lost art. We only have 2 or 3 guys at our shop who can do it. Old timers always have some good knowledge to pass down if they like you 😉

Yeah, not my cuppa either. But it is a work of art.

Very little is done manually these days when it comes to metal forming. Heat pipes I’m sure are bent using a cnc bender. We use Haas CNC lathes and mills at work. We also have a Hypotherm plasma cutter, and Lincoln Electric for welding.

YouTube has some cool cnc stuff if you have some time. The majority of my time is spent on lathes, awesome stuff guys. After 7 or 8 years it still makes me moist.
I grew up hand machining things, before they become CNC. I know everything is now CNC, but I still think of CNC being a computer controlled milling machine.

In other news, had to unmount my cooler today to do a PSU swap. Turns out I went a little light on the TIM, dropped about 3-4 degrees, not bad.

Always check your spread people, its worth it.

And maybe a sound recording with the delta temps normalized?

Wouldn't be the most scientific thing to do, but I might give it a shot anyway. That is if I can actually get them here, would be my first time ordering china domestic stuff through an agent.

Would be a good trial to test out the the waters on buying stuff directly from china tho, there are some really cool boutique SFF cases out there that look way better than what's available in the west atm.
Something like this would be pretty sweet:https://www.chiphell.com/thread-2007663-1-1.html

If you get any, could you maybe test them by comparing CPU temps with other fans you have? All you would need to be sure CPU temp is accurate is to monitor and record air temp into cool fan at same temp you record CPU temp. That way we eliminate that variable .. which is biggest unrecorded / reported variable in most cooler testing.

No chance, I basically have none of the above.
