Hello Everybody,

So I'm quite taken aback by the loud fan noise generated by the stock SP20 fans, was all along thinking it would be comparable in terms of noise to the S3 series.

Has anybody managed to replace their SP20 fan to something which solves the noise problem? Any known models/plugs/settings to take note of? I reallllllly need to get the fan issue solved if not the miner is just going to be switched off. Looks like I have to reassess my definition of "home mining".

Cheers

Really do we need a new thread for this?

https://bitcointalk.org/index.php?topic=521520.msg9469805;topicseen#msg9469805

Its a 200+CFM 60+ db fan on a non-standard power connector. Good news is that the unit doesn't care if there is a fan plugged into the header.

I've currently got two Coolermaster Jetflo 100CFM fans powered from the PSU, one replacing the internal fan and one on the outside pushing air in at the back.

Not-so good news is thats not enough airflow to keep the unit performing at spec, sweet spot seems to be just under 1.4TH

Temp Front / Back T,B
33 °C / 86,87 °C

But its now normal miner sound levels Smiley

Going to try a 150CFM fan, I guess you could solder the custom connector onto the fan wires if you wanted a stock look

I would argue we do, the other thread is over 430 pages discussing a slew of issues. This thread is specific and when you come in here you should be able to figure out what the topic being discussed is quickly. Gives the issue more visibility imo. Maybe help someone from making a bad decision for "Home Mining".
