Compact 40mm CPU Cooler

This OEM Industries cooler uses a 40mm square frame with a ball-bearing fan. It draws 5V at 0.21A through a two-pin connector. The unit suits small-form-factor boards or embedded systems that need a low-profile heat sink.

Verify Mounting And Voltage

Check that your motherboard or controller offers a two-pin 5V header with the correct pin spacing. Confirm the mounting holes match the 40mm square pattern before ordering. Ensure the chassis height allows the cooler to sit flat without fouling side panels.

Fits Tight Builds And Frees Headroom

The slim profile leaves clearance for memory modules and expansion cards directly above the socket. Ball-bearing construction reduces the risk of bearing noise over long uptime. No LED lighting means the cooler stays invisible inside closed enclosures.

Questions about this item

Does the 40 mm square cooler ship with mounting hardware or must I buy brackets separately?

The listing shows only the 4010 fan unit with its 2-pin lead; no screws, brackets or thermal compound are mentioned, so plan to source mounting parts yourself.

Should I choose the 5 V 0.21 A ball-bearing model or look for a different voltage?

This specific 1604KL-01W-B50 runs on 5 V at 0.21 A with a ball bearing; select it only if your header or controller matches that voltage and current.

What does the 5 V 0.21 A rating mean once the fan is installed in a system?

It indicates the fan will draw 0.21 A from a 5 V supply, so the header or fan controller must be able to deliver that current continuously.
