Use four series connected 12CM 76CFM quiet fan to replace one noise Delta FAN.

Can it applicable?

The low noise fan specification:

Air Flow: 76CFM

Speed: 1600RPM

Bearing Type: Hydraumatic

Dimensions: 120*120*25

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

if you want to replace the fan, please use ONE 12038(or 12044) size, 4PIN PWM, 12V , with at least 3600RPM maximum speed.  ball bearing is recommend.

a 1200rpm 12025 fan (or 2 in series ) will of course kill the machine.

12038fan at 3600 RPM? Oh, my god! How the noise will be!
Looks like a water cooling is necessary if I got a machine!

For future reference those number are decoded as:

"If you want to replace the fan, please use ONE 120mm x 38mm (or 120mm x 44mm) size, 4PIN PWM, 12V , with at least 3600RPM maximum speed.  ball bearing is recommend.

a 1200rpm 120mm x 25mm fan (or 2 in series ) will of course kill the machine."

treat it as a server or workstation. this is NOT a HTPC or something like that.

if (only if) we build a 1U blade, we will certainly put 4 or more DF04056B12U (4056size, 13900rpm)on it.
