Hi all I'm a bit confused as to the correct CFM of the iCUE H150i Pro XT. The official product page says max airflow 75 CFM. However it comes with 3 x ML120 fans which are also 75CFM each according to its product page . Does this mean that the overall CFM of the H150i Pro with 3 x ML120s is capped at 75CFM and therefore each fan only running at a third of their capacity?....OR is the total max airflow 3 x 75CFM = 225 CFM? I did email corsair and they said its capped at 75CFM which didn't seem to make sense to me so wanted to double check here what the deal is from those who have experience with this model. Any help much appreciated as I'm trying to work out how to balance my airflow! Thanks
I am contemplating buying the ML120 fans to replace the stock SP120L fans on my H80i v2 cooler for better cooling performance at lower noise levels, since I came to know about the great performance of ML series fans from various sources. But after checking the specs of both these fans in official products pages I doubt whether there will be any benefit to the cooling/noise as the ML fans have almost same specs as the SPL's. Below is a comparison of max specs of both set of fans. Stock SP120L specs:- 2435 rpm, 70.69 CFM, 4.65 mm-H2O @ 37.7 dBA ML120 specs:- 2400 rpm, 75 CFM, 4.2 mm-H2O @ 37 dBA From the above comparison it can be seen that -- SPL has +35 rpm over ML; ML has +4.31 CFM over SPL; SPL has +0.45 mm-H2O over ML; ML has -0.7 dBA over SPL From a pure specs perspective, ML has better CFM but SPL has better static pressure at almost same speeds and noise levels. But since specs may not necessarily translate into real-world performance so I am a bit confused whether the ML's are worth it to upgrade. I have searched but couldn't find any user/reviewer stats comparing the two sets' performance on the H80i v2 specifically. So I am seeking info and advice from any fan experts and those users who have the H80i v2 stock replaced with ML fans and tested the performance difference before/after such an upgrade.
