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

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.
