Aio push/pull fans

[Gru]

So i have two noctua 140mm fans laying unsed since i’ve mounted my corsair h115i (280mm radiator). I’m thinking about using the two noctua fans and make it a push pull configuration since I believe it would help with airflow because my case front panel is very restrictive (phanteks p400). Would it be a problem to mix the included corsair fans with the noctuas ones?

Not if you use the DC bios setting. They can be rpm controlled in Windows software. If you use common sense and connect two of the same spec or model fans to a fabln splitter, you'll be able to keep them rpm synced

If it is on a motherboard, voltage can be controlled but not the better one.

Push pull has no real benefit anyway, the radiators are too thin for it to have any real effect, unless the fans you're using aren't efficient enough with pushing/pulling air through the radiator.

My H115i RGB Platinum in push-pull with 4 ML140s (2 of which came with the unit) was bested by my Deepcool Castle 360 RGB V2 with just the 3 stock fans in pull. What matters with coolers, whether it be air or liquid, is the fin density of the heatsink/radiator. The heat needs somewhere to go before it can be cooled, and more fin density generally allows for better cooling with sufficient airflow.

You can do push-pull if you want to, but you won't really gain anything except the ability to run your AIO fans at a lower speed to reduce noise with less cooling performance loss.
