Under Pressure: Parvum F1.0 VS NoiseBlocker eLoop B12.2 Static Pressure Fan Comparison

« The Fans Continued- Noiseblocker e-Loop B12-2

Test System

To ensure as little contamination as possible all the components, except for the fans stayed the same between the test, and after each test the machine was allowed to wind down for an hour. The Black Ice Nemesis 240 Radiator was front mounted inside a Fractal R4 MIDI with the test fans in push configuration.

Parvum Chart

Parvum F1.0


Due to the cheaper price (savings of $3USD per fan), PWM style connector to control fan speeds and its overall better performance in the benchmark, the Parvum F1.0 trumps the Noiseblocker B12-2 as the better fan choice on the Hardware Labs Nemesis GTX 240mm radiator. The benchmark diagrams show that the Parvum fans had an average 4-5C temperature difference compared to the Noiseblocker B12-2 on both the CPU and GPU. With that said the Parvum fans at full speed were louder, but not to a level where you could hear them over your media experience, a small trade off in my opinion for the performance of the cheaper solution.

  1. Are you sure this is an actual review? The testing done was really, really bad. The Parvum fans at full speed are much faster than the B12-2, so of course it will result in the loop being cooler while being noisier. If you are looking from a price point of view only then why not get OEM Delta fans at $9 or so each that can go to much higher speeds while being cheaper?

    Oh and don’t even get me started on how you determined it cools better!
