Our take on the Zguuel 40mm PC Case Fan, 40x40x10mm Quiet Mini Cooling Fan 3-Pin 12V for Small Computer Case CPU Cooler 3D Printer DVR NAS

The Zguuel 40mm is a small 40x40x10mm 12V DC brushless fan with a 3-pin connector, rated at 3000RPM and about 22.8CFM with an 18dB(A) noise claim. It uses an oil bearing and a short 18cm cable, so it fits tight spots in small cases, CPU coolers, 3D printer enclosures, DVRs and NAS boxes. It is a basic single fan with no PWM control and no RGB, so it competes on size and simplicity rather than features. Buyers should expect a budget sleeve-bearing fan with a limited lifespan compared with magnetic or fluid-dynamic bearing fans from Noctua, Arctic or Noctua-class rivals.

Questions and answers

Will this fit a standard 40mm fan mount?
Yes. It measures 40x40x10mm, the common 40mm fan footprint, so it fits mounts drilled for that size. Check clearance for the 10mm thickness.
Can I connect it to a 4-pin motherboard header?
It has a 3-pin connector. It will plug into a 4-pin header and run, but you won't get PWM speed control; speed follows the 12V supply.
Is it quiet enough for a NAS or DVR?
The rated noise is 18dB(A) at 3000RPM, which is quiet for a 40mm fan. Small fans get louder as they age, and oil bearings can develop noise over time.
Does it come with screws or a fan adapter?
The listing includes one 40mm fan. Screws and a Molex or header adapter are not listed, so plan to supply your own mounting hardware.
Can I run it at lower voltage to reduce noise?
Yes. It is a 12V DC fan, so running it from a lower voltage slows it and cuts noise, though airflow drops too. It may not start reliably below about 5V.
Is it suitable for a 3D printer enclosure?
It can work for light enclosure or electronics cooling at 12V. For hot chambers or long continuous runs, a higher-grade bearing fan is a safer long-term choice.
