Hi,
I would like to ask you if anyone tried to use the Fan simulator to eliminate the original loud fans.
Remove the hash boards from the case and add external quiet fans to reduce noise. Like a 2fans/hash board
antminer will be in an air-conditioned room where it is about 16 degrees.

it will work?
has anyone tried this solution?

Thanks

Waste of money.

braiins lets you run fans very low on the s9s.

Just lower freq. and the fans to 20%

the correct bitmain firmware lets you lower the freq and the fans on the l3

cost is zero and they are much quieter.

As BitMaxz there are some firmwares that will allow you to run without fans.
However, the way the boards are designed you do have to get a large amount of air moving over the heatsinks.
You need a bit of positive air pressure moving through them.

Block halving is coming.

They will work if you can bypass the "fan sensor" and give a fake signal but mostly they don't need any device(Fan simulator) just to bypass the fan check. You can bypass the fan check on different firmware like in Braiins OS.
