Rank #3 in Best Case Fans 2026: 9 Ranked by What a Fan Actually Costs
CORSAIR RS120 120mm PWM Triple Pack (£8.00 a Fan)
Price and rating as shown on Amazon when we collected them. Both change.
The Corsair RS120 is a 120mm PWM case fan sold as a triple pack, and it sits at number three in this guide. The headline number here is the one that runs through the whole category: £23.99 is not the price of a fan. With three fans in the pack, that works out at roughly £8.00 each — more per fan than the £4.30 of the £21.49 ARCTIC five-pack or the £3.73 of the £18.66 pack, but the same kind of arithmetic that makes a page price misleading until you divide it.
The listing also resists being read straight through. Corsair calls the RS120 low-noise and credits its Magnetic Dome bearing with quiet operation, while the spec table quotes 36 decibels — the highest noise figure quoted anywhere in this guide's comparison, against 31 dB for be quiet! and 25.1 dB(A) for Noctua, and those two units are not the same unit either. The pack count has the same problem in miniature: "number of packs" is 3 and "unit count" is 3.0 count, but "number of items" is listed as 1. Everything on this page comes from the Amazon listing, not from testing we have carried out.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Fantastic fans for the value. Daisy chaining these together took me only a few minutes and running them all off 1 PWM fan header meant there's minimal cable clutter so very tidy.Would recommend these for their performance value and installation being easy.”
Verified purchase“Just a heads up. If you want to daisy chain them make sure one fan is plugged into the motherboard, and then plan around it with the extensions. Had to remove and reinstall because mine ran too short.”

Questions people ask
How many fans do you get for £23.99?
The Corsair RS120 is sold as a triple pack: the listing gives a unit count of 3.0 count and a pack number of 3, so £23.99 works out at roughly £8.00 a fan rather than £23.99 for one.
How do the Corsair RS120 fans connect?
Corsair says the RS120 fans daisy-chain, so several can be run and controlled through a single 4-pin PWM connector rather than one header each.
How loud are the Corsair RS120 fans?
The listing gives a noise level of 36 decibels, while the bullet points describe low-noise operation and a Magnetic Dome bearing that minimises noise. At 36 dB it is the highest figure in this guide's comparison.
What speed and airflow do the Corsair RS120 fans run at?
Up to 2,100 RPM and up to 72.8 cubic feet per minute of airflow, according to the Corsair listing.
Are the Corsair RS120 fans suitable for a radiator?
Corsair lists 4.15mm-H2O static pressure and AirGuide anti-vortex vanes, and states the RS fans work well as radiator fans.
Does the listing say how many fans are in the box?
It contradicts itself: number of items is listed as 1, while unit count is 3.0 count and number of packs is 3. Corsair's own product name calls it a triple pack.
What warranty comes with the Corsair RS120?
Five years manufacturer warranty, as listed.
