Avalon ASIC powerful noise fan replacement, can it feasible?

[leiyplane]

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

Get some Zalman cooler, will do the work even better, I replaced them in mine with Thermaltake

Here you have a list of 120mm fans:

Just sort them by noise (dBA) there are some ultra quiet

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.

Have a bunch of units with this type fans... Oh my got, this will be impossible to stay for long in room with it Especially if ambient temp will be high

worthy bump i had the same question and some more things to add, currently moding some miners so they dont sound like a jet plane taking off...
Question has anyone managed to locate 120mm fans that have a rpm of 3600RPM cause i cant find them anywhere.... ?

What fans is everyone using in the avalon am looking to change my to much noise so i need 3000 rpm fans? or 1200 to 2000 super quiets will work?

actually they replied already few posts above; 1200 rpm is too less, you will kill your hw !
