Trying to quiet down L3+ - changing fans?

[philipma1957]

Nope no no no no.

leave the fans alone and build something like this

this is for soundproofing only.

as for fan quality

the noctua will not cut it.

if they are deltas on the gear they are good.

sometime  they put shitty ones in

sometime these are the deltas.

these may be enough

If you insist on  a different fan then oem

I found  this one to be close to good

I'm so glad you guys are actually answering my question.....

Get a small, high rpm fan (3-4cm in diameter, they are usually speedy ones), hide it in a small box, cover by foam if still noisy, plug in as factory fan. Noctua fans connect to 12V directly or by a regulator. Motherboard should detect hi speed of minifan and go

The noctua fans I bought are the 4-pin ones with the speed regulator on them.

Yours is a novel idea, but - how would I power the Noctua fans if I am using the headers on the miner to run those little high-speed fans?

The noctua need to be returned they are not good enough

I have used more then 50 different fans. With miners.

Don't set speed manually, or hack the watchdog program to lower speed of the vents, they need proper cooling, or else they will burn and become useless.
You need a fan that has capability to go at about 6000 rpm of size 120mm x 120mm, the same size of the factory ones, but less noisy. I am still also looking for a good model to use, I tried the Scythe Ultra Kaze and ended up to be even more noisy than the standard ones. I wonder if placing 2 of some less noisy model in a row for each side would do the trick. If anybody can try the Gelid Silent fans, please report if they are good, I'm trying also some models when possible

Why not just flash the L3++ with a custom firmware such as Bliss or AsicFW and choose the submersion cooling options(disabling the fan fault) and then use whatever cooling method you choose?
