PowerEdge840 120mm Case Fan Specifications?

Question

The CPU Case Fan that came with PowerEdge 840 is very noisy. Like to replace this fan with a better airflow with lower noise levels. The fan in the system is Dell P/N: UG891, Made by Delta Electronics (Model Number: AFC1212DE), 120mm x 120mm x 38 mm, DC12V, 3.0A, 4 pin connector.

Can someone please provide the missing details on this Case Fan:

RPM = ?

CFM = ?

dBA = ?

Are there any replacement fans that I can purchase?

Thank You

The info you are looking for on that fan model number is here;

RPM:: 3900 RPM

Air Flow:: 148.34 CFM

Noise Level:: 51 dBA; You can find these fans WITH the housing and shroud through numerous brokers and dell partnered parts suppliers. I buy from a place named velocity tech solutions for my older hard to get parts. good people.; cheers

I replaced the fan with a SilenX Effizio 120 mmm fan EFX 12-15 (go to Ebay) with the following info

sku: EFX-12-15

rated dba: 15

dimensions: 120x120x25mm

rpm: 1400

cfm: 74

operating voltage: 6-12v

current draw: 0.11A

power consumption: 1.32w

bearings: 3rd generation fluid dynamic bearings

--------------------

I connected this fan to a molex plug (several of this are avail inside Dell PE 840), and so far things have been great.

I think the original fan with 148 cfm is an overkill.

Just an idea.
