[SOLVED] EK fans and AIOs

[mltouva]

I am planning to pick up an EK240mm AIO, and I want all my D-RGB to match throughout my system. I am wondering if I buy EK-Vardar EVO 120ER D-RGB fans if they will match the ones that come with the radiator. Additionally, although EK fans are made for radiators, would they be sufficient for case intake and exhaust? My main reason for buying these fans are just to get the RGB to match, because I know that not every fans RGB LEDs are the same.

EK-Vardar S 120ER D-RGB (2 piece) is what comes on the AIO. Looks to be the same thing as the Evo.

Shouldn't be an issue using them, just don't expect wonderful performance at exhaust since they Are high static pressure, designed for radiator fans and not designed for uber cfm which is what benefits an exhaust fan most.

Thank you for the help, im thinking that even though they are high static pressure fans they still have very good cfm at 70 so they will still preform very well.

That cfm is misleading. That's at Maximum rpm, 100%, not in the more normal 30-60% range, and the performance curve is not linear (a straight line). At 50% rpm it's more likely you'll get @ 40% of the 70cfm. (maybe less).

A high cfm/airflow fan has differently designed blades, so will put out more cfm at lowered rpm than a high static pressure fan.

It's all about blade design. A high sp fan might be putting out 10cfm, but has enough pressure from the blade design that just about all 10 of that cfm is forced through the radiator. A high cfm fan at the same rpm might be putting out 30cfm, but has so little pressure behind it that only @ 5cfm actually gets through, the rest squeaking out the gaps between the rad/fan or even backfeeding through the blades.

A high sp fan MOVES a mediocre amount of air, a high cfm fan moves a TON of air. Significant difference, especially at exhaust where you want as much flow as possible, without caring where the air goes after its exited the case.

Oh ok I didnt know that. Do you have any recommendations for an alternative. I just wanted the same fans so the RGB is the same but if you have any recommendations that would be better i could use them.

I also currently have the deepcool cf120 s around my case so i am wondering if these would perform better than those at normal use.
