Manufacturer description
The Wathai 120mm case fan ships as a 2-pack built for the jobs a stock fan won't cover. Each 120mm x 25mm frame runs on 12V DC at 0.15A, spins at 2000RPM, and moves 66.7CFM at a rated 28dBA — enough static airflow to pull heat out of a drive tower or push exhaust through an electronics enclosure. The sleeve bearing is rated for 35,000 hours of service. What separates this Wathai fan from a standard PC case fan is the 2-pin XH2.54 connector and 28cm (11 inch) lead. That wiring skips the motherboard header entirely, so you can wire the fan straight into a 12V supply in an amplifier rack, RV…
SpecPicks Verdict
SpecPicks scored Wathai 120mm x 25mm 12V Computer Case Cooling Fan 12 Volt 2Pin DC… using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Wathai'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. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Can I plug this into my motherboard fan header?
Not directly. The fan terminates in an XH2.54 2-pin connector, not a 3-pin or 4-pin PC header, so a motherboard install needs an adapter or a direct 12V wire-up.
How loud is this fan?
Wathai rates it at 28dBA per fan at its 2000RPM full speed. With no PWM control, it runs at that level any time power is applied.
How much air does it actually move?
Each fan is rated at 66.7CFM at 2000RPM, drawing 0.15A from a 12V DC supply.
What are the exact dimensions?
120mm long x 120mm wide x 25mm thick per fan, or 4.72 x 4.72 x 1 inches - the standard 120mm case fan footprint. The cable is 28cm (11 inches).
Do I need to buy mounting hardware separately?
No. The 2-pack includes a fan grill plus mounting screws and nuts for each fan.
