Product ReviewsCooler Master R4-S2S-124K-GP Case Fan

Cooler master fans

These fans are very good, at full speed they are barely noticeable. Only complaint it is wish they would have made the connection all black wiring instead of yellow and red, also if they were a little longer that would be great. Overall great fan for priceRead full review...

Quite, Cheap, Good quality I'm happy with them

seems like a nice quite good quality fan., seems to operate on low rpm when hooked up directly to my motherboards 3pin. really quite but not powerful enough to use as an extra on my radiator probably just my mobo though and a fan controller would fix it I'm pretty sure., but for a "case" fan probably fine as is which is how i'm using them now.,Read full review...

Good value, quiet, and works well

Whether you're just running a couple light tasks or heavy video rendering/gaming, the fan keep up and the temperature of the case and CPU hangs low, like it should. Barely any noise. Coupled with liquid cooling, you'll have a tower that's dead quietRead full review...

Low CFM, but very quiet

not high cfm fans, but very quiet
sleeve bearings wear out faster than ball bearing, but for the price you can't complain about the 30Khr expected lifespan.

Great mid-priced quite fans with PWM 3 pin connector

Moves a decent amount of air quietly, these fans are a good buy at the price of $10 or less per fan. Compared to a Norco 120mm fan that can go for upwards of $30 per fan these have a good price to performance ratio. The static pressure is a bit on the weak side, so I do not recommend that they are used in thick (40-60mm wide) water cooled radiators. But they work well as both front or rear fans, and as heatsink fans.Read full review...

Good Value

Review: Cooler Master R4-S2S124K-GP Silent Fan 120 S12 120mm 4-Pack
I had a project where I was resurrecting 3 old motherboard / systems. None of the 3 cases I was using had side windows so 'lighted' fans were unnecessary. I've used this 4-pack in computer builds for decades.
They are a good value for the money. They last long enough are inexpensive to replace. Read full review...

Is it on?

The fans are spinning at full speed, they're nearly silent, but I can feel only the slightest amount of air movement. Perhaps the fans I have are defective.
