Cavalier 3 - Technical specs for case fans?

Recommended Posts

Psycho Dad    0

Hello!

I bought a Cavalier 3 midi tower and want to exchange both case fans. The new ones should be more silent and should have PWM control. I need the technical specifications of the old fans for comparison, but I can't find them on the Cooler Master homepage. The serial numbers of the fans are:

A12025-12RB-4JN-M2 and SFA 1225LU-12A for the 120 mm fan

A8025-18CB-4JN-M2 and SFA 8025LS-12A for the 80 mm fan

Does anyone have the technical specs for those fans? I'm especially interested in the RPM, air flow and noise values.

Thanks,

Psycho Dad

I couldn't find the specs of your fans online, but here's what I noticed about CM's serial numbers for their fans. The 2nd number in the serial number is the RPM and the letters that follow it is the bearing type. This is only a guess though

So, for the A12025-12RB-4JN-M2, it's 1200RPM and rifle bearing(?) (most 120MM CM fans at 1200RPM are about 40CFM and 20dBA). For the A8025-18CB-4JN-M2, it's 1800RPM and it's sleeve bearing (most 80MM CM fans at 1800RPM are about 20CFM and 22dBA).

Good luck to you :wink:

I am pretty Zenphic hit it on as I have the following which confirms hit guesses:

CM 80mm blue LED: A8025-18CB-5BN-L1

Bearing type: Sleeve

Speed: 1800RPM

Air Flow: 22.84 CFM

Noise: 22dB

CM 120mm Blue LED: A12025-12CB-5BN-L1

Bearing type: Sleeve

Speed: 1200RPM

Air Flow: 42.73 CFM

Noise: 22dB

Also something to add about identifying the specs is the first 4-5 numbers.

A12025 means it is a 120x25mm fan.

A8025 means it is a 80x25mm fan.

One thing you have to keep in mind is the number on the back of a fan is not the model number so that is probably why none of the fans show up on CM's website.

Example:

"R4-L8S-18SB" written on the packaging but the number on back of the fan is "A8025-18CB-5BN-L1"

"TLF-S12" writtin on the packaging but again the number on the back is "A8025-18CB-5BN-L1."

Okay, those values should help me find good replacements. Thanks!

Yes, I also thought that the first number gives the dimensions of the fan.

Thanks for your help as well!
