Manufacturer description
The GDSTIME 40mm fan 2-pack is a drop-in replacement for noisy or failed 12V 4cm fans. Each brushless DC fan uses the standard 40 x 40 x 10 mm (4010) frame, so it fits motherboard north and south bridge heatsinks, 3D printer hotends, small power supplies, DVRs, NAS units, network switches and hard drive bays. The specs are clear. Each fan spins at 4500 RPM, moves 4.95 CFM of air and is rated at 23.9 dBA. Static pressure is 0.075 in H2O, and each fan draws only 0.06 A, or 0.5 W, at 12V. The fans start at 7V DC and run anywhere from 7 to 13.5V DC, which gives you some room on boards with a…
SpecPicks Verdict
SpecPicks scored GDSTIME 40mm Fan 3-Pin 12V 40x40x10mm Mini Computer Case PC CPU Fans… using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. GDSTIME's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cooling & fans of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Will this fan fit my 3D printer or NAS that uses a 4010 fan?
Yes, if the existing fan measures 40 x 40 x 10 mm (1.57 x 1.57 x 0.39 in) and runs on 12V. GDSTIME lists 3D printers, NAS units, DVRs, switches and hard drive enclosures as intended replacements.
How loud is the GDSTIME 40mm fan?
Each fan is rated at 23.9 dBA at its 4500 RPM rated speed, which puts it in the quiet range for a 40mm fan.
Can I plug it into a 2-pin or 4-pin header?
The fan has a 3-pin connector with power (red), ground (black) and tachometer (yellow) wires. It plugs into a standard 3-pin header and will run on a 4-pin header at voltage control, without PWM speed control. For a 2-pin socket you would need to adapt the connector, and RPM reporting would be lost.
Will it run at lower voltages like 7V or 9V?
Yes. The rated start-up voltage is 7V DC and the working range is 7 to 13.5V DC, so it will run slower and quieter below 12V.
What comes in the box?
Two 40x40x10mm 12V 3-pin brushless fans and 8 screws and nuts for mounting. Each fan has a 9.84-inch cable.
