Pros & Cons

Pros

  • ✓ 10.7mm depth fits where 25mm 80mm fans physically cannot
  • ✓ Metal finger grill included on the intake side
  • ✓ 2-pin leads are swappable in the connector to match old fan polarity
  • ✓ Runs on anything from 7V to 13.5V, so undervolting for quiet is easy

Cons

  • ✗ 18.9 CFM is low; thick 80mm fans push roughly double
  • ✗ 0.13 In H2O static pressure struggles through dense heatsink fins
  • ✗ 25.6 dBA at a fixed 2500 RPM with no PWM speed control
  • ✗ 2-pin plug means no RPM tachometer signal to the motherboard

Manufacturer description

The GDSTIME 80mm ultra thin fan solves a specific problem: the 25mm-deep case fan that will not physically fit. At 80 x 80 x 10.7 mm (3.15 x 3.15 x 0.42 in.), this GDSTIME brushless DC fan slides into HTPC shells, Mini ITX and MATX builds, external hard drive enclosures, laptop coolers, and 3D printer power supplies and control boards where a standard 8cm fan bottoms out against a panel or drive cage. It is also a common replacement for tired 12V 80mm fans in EVGA GTX cards and older PSUs. The spec sheet is honest about what a 10mm-thick rotor can do: 18.9 CFM of airflow and 0.13 In H2O of…

SpecPicks Verdict

SpecPicks scored GDSTIME Ultra Thin 80mm x 80mm x 10mm 12V Computer PC Brushless DC… using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. GDSTIME's power supplies 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 power supplies 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 fit where a normal 80mm fan is too thick?

That is the point of it. The frame is 80 x 80 x 10.7 mm, roughly 14mm shallower than a standard 25mm 80mm fan, which is what makes it work in HTPC, Mini ITX and MATX cases and external drive enclosures.

How much air does it actually move, and how loud is it?

GDSTIME rates it at 18.9 CFM and 0.13 In H2O static pressure at 2500 RPM, with a noise level of 25.6 dBA. Slim fans trade airflow for depth, so expect less throughput than a 25mm fan.

Can I plug this into a motherboard fan header?

It is a 2-pin fan: red is positive, black is negative. There is no tach or PWM wire, so the board cannot read or control its speed. Many buyers run it off a 12V DC supply or an adapter instead.

What if the polarity on my old fan's connector is reversed?

You can swap the red and black wires within the connector housing to match your existing plug. GDSTIME calls this out directly for replacement installs.

Does it come with mounting screws and a guard?

Yes. Matching mounting screws are included, and a metal fan grill on the fan side protects your hand and keeps cables from reaching the blades.
