Not long ago, we tested two popular case fans, pitting Noctua’s NF-A12x25 G2, an industry legend, against the also well-liked Arctic P12 Pro. We had some surprising results, as the Arctic fan almost kept up with the much pricier Noctua. However, Arctic also sent us some P12 Pro’s of the RGB variety, so we thought it would be fitting to put Artic’s colorful spinner up against some competitors in its own price category.

In this round of testing we’ve rounded up five 120mm RGB fans that don’t cost a whole lot, so here, you won’t be seeing Lian Li’s fancy LCD-infused, wireless, infinity-mirror fans. Instead, we’re pinning the P12 Pro up against Be Quiet’s Light Wings LX, Fractal Design’s Aspect 12 RGB, Phanteks’ M25 G2 RGB, and finally, Levelplay’s Combat Fan 120 A-RGB. This last one was sent to us as a surprise, and I thought it was fitting to include in the roundup.
Let’s dive straight into the testing.
Testing Methodology
For evaluating PC fans, there are two main terms you should be aware of: Airflow and Static Pressure.
Airflow is easy – how much air does a fan move (through a wind tunnel in our tests) when not burdened by a radiator, mesh, or any other restriction.

Static pressure can be measured by placing the fan on a wind tunnel, closing the end, and measuring the pressure generated with a sensor, which spits out a value in millimeters of water. The higher the number, the better a fan is likely to be at overcoming restrictions.
However, I find that a fan’s measure of static pressure isn’t actually all that useful – all it tells you, really, is how well a fan can push air up against a wall, which is obviously not how you want to position the back of your PC. Instead, I prefer to test for noise and airflow through a radiator and intake mesh, as well as the standard suite of unrestricted tests for a more nuanced, real-world picture.
