Question CPU AIO coolers but with different fans

[Autocon487]

I've been thinking of buying either the Corsair h100i pro or the hydro series h100i v2. I want to replace the fans with the corsair ll120 rgb fans for perhipheral reasons. How much would it effect the cooling? (It will be placed on top of my case as an exhaust)

They are high aitflow low static pressure fans. 1.61mmH20 vs 4.65mmH20. They'll likely have a significant impact on cooling performance. Look for high static pressure RGB fans. Radiators put up a lot of resistance. Same goes with cases which have restricted intakes, ie glass front with small air gap and filtered
