Title: Bearing Goofed*
Post by: tp4tissue on Sat, 23 January 2021, 16:01:48: Applied krytox grease to a ball bearing fan, Now it makes this wet licking noise, like someone handwashing cloths in the river...

I did hear it make kind of a grinding noise before from cold bootup. Maybe it is done. or at some point seized.

Easy comedy for the audience, but Tp4 was traumatized when he turned the machine back on.

The adda Hypro bearing fan (fluid bearing) on the gpu is great, popped the blades off, input krytox, perfectly smooth.

The bbear cpu fan is the original though, so it's sentimental, Sighhhhhh

this reminds Tp4 of why he h8s ball bearing fans. Fluid bearings FTW.

Post by: yui on Mon, 25 January 2021, 08:23:43: i have a few server fans with ball bearing that came from a 1st generation compaq proliant, still working flawlessly something like 40 years later, i do not think the hate is deserved. although fluid bearing are more efficient and silent, so yeah overall better, but good ball bearings can last a long time

they keep working, that's not the problem, the problem is they get noisy.
