Cons
- ✗ 26.26dBA at 6000RPM is audible in a quiet room or living space
- ✗ No speed control, PWM, or inline switch - full RPM whenever powered

Manufacturer description
The ANVISION 2-Pack 40mm USB cooling fan solves the problem every small-enclosure build eventually hits: heat with nowhere to go and no spare motherboard header to fix it. Each 40x40x10mm fan terminates in a USB plug on a 500mm lead, so you power it from a wall adapter, a powered hub, or the same 5V rail feeding your Raspberry Pi, NAS shell, DVR cabinet, or retro PC case mod. No PWM header, no adapter chain. Spinning at 6000RPM, each fan pushes 7.32CFM at 2.98mmH2O of static pressure while drawing just 0.4W rated, and the dual ball bearing system is rated for 50,000 hours at 25C rather than…
SpecPicks Verdict
SpecPicks scored ANVISION 2-Pack 40mm x 10mm DC 5V USB Brushless Cooling Fan using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. ANVISION'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
Can I run this fan off a USB phone charger or power bank?
Yes. It is a 5V DC fan with a USB plug, drawing 0.08A rated and 0.20A maximum, so any standard USB-A port, charger, or power bank supplies it easily. Operating range is 4.5-5.5V.
How loud is it?
ANVISION rates it at 26.26dBA, measured at rated voltage in an anechoic chamber with the fan suspended and a microphone at the standard distance. At 6000RPM you will hear it in a quiet room; in a closet or cabinet it fades into the background.
Will it fit a standard 40mm fan mount?
The fan is 40 x 40 x 10mm, so it matches 40mm mounting hole spacing but is only 10mm thick rather than the common 20mm depth. Check your bracket clearance and screw length before ordering.
How much air does it actually move?
Each fan is rated at 7.32CFM with 2.98mmH2O of static pressure at 6000RPM. That is sized for Raspberry Pi cases, small NAS and DVR enclosures, receivers, and router shelves, not for cooling a full-size PC case.
Is there a warranty, and how many fans come in the box?
The package contains two DC brushless fans and ANVISION lists a two-year warranty. Life expectancy of the dual ball bearing system is rated at 50,000 hours at 25C. Check the product listing for current warranty terms.
