Fan solution searching for a problem

[rUnThEoN]

So I salvaged some 120MM Fans from a older workstation/server and finally took my time to get them running on my testbench.

This fan does 5000 RPM @ 12V/3.3A (thats the reason for the molex connector) and feels like its lifting off if its by itself.

 

I have 2 of those and a different one with less RPM currently attached to my cpu cooler.

 

So any suggestions what to use these for? Currently im either thinking of either doing a airduct for the cpu cooler which just blasts the air for maximum air cooling (maybe I'll increase my OC with that) or trying to get a cheap watercooling and slap the fans onto that.

Wow i can't imagine a fan like that being usable. These must be deafening. Is your PC in another room?

that fan runs at 1500 rpm at Idle - basically the power is only needed if the PC heats up which currently only cpu benchmarks do.

It'd be interesting how a NH-U12A would perform with 2 of those.

Aircooling at it's limit.

 

But going for a cheap watercooling solution wouldn't make much sense because then the pump or a cheap coldplate is likely a big bottleneck. I can pretty much only think of a good CPU waterblock, a decent res-pump combo and a VERY thick 240mm rad.

 

No offense, but for anything other than that these fans seem useless for me. Maybe that's just my silent-focused thinking, as even noctua NF-F12's at 800RPM are too loud for me

Put them in a friend's PC and hide them to prank him

@kodan - thanks for your input, maybe I will do that later this year.

 

@Stahlmann - I currently have a Arctic A30 mounted on my ryzen 5 3600, would that qualify for max air cooling?

Also I think spending money on a watercooling defeats the purpose of having a bang4buck cpu since instead spending it on a bigger cpu gives more then ocing the small ones.
