Compact 40 mm case fan
The Fans RDM4025S1 is a 40 mm square frame case fan measuring 25 mm thick. It runs on 12 V and draws 0.14 A through a two-wire connection. The 4025 form factor fits tight chassis where larger fans cannot be mounted.
Suits small-form-factor builds
This fan suits builders working with compact enclosures or legacy hardware that requires a 40 mm footprint. It is not for systems needing high airflow or PWM speed control. Buyers who want larger diameter fans or four-wire regulation should look elsewhere.

Questions about this item
What voltage header do I need on my motherboard for this 12 V fan?
It runs on a standard 12 V DC supply, so a 4-pin or 3-pin motherboard header rated for 12 V will power it.
Will the 40 mm frame fit the same mounting holes as my old 4025 fan?
Yes, the 40×40×25 mm dimensions match the 4025 form factor, so existing screw holes line up.
