Static Pressure and Airflow

[aprilie21]

First of all, I must excuse myself for future typing mistakes, there will be a few of those, I promise... and if this topic allready exists (i didn't find it) i am also sorry

 

I just got a new PC, and my CPU is heating up a bit, so I have to get a new cooler. I measured everything, and the cooler I've gone with (and that's about my budget for the cooler) is the CoolerMaster Hyper 212 EVO.

I watched some reviews and unboxing and seen that it can be equiped with two fans... here comes the problem:

 

Now I know that the best fan for pushing air through the radiator is a static pressure optimized one, what should the other one be? Static Pressure or Airflow? It looks something like this (arrows tell which way air is going).

 

 

S.P. Fan --> Radiator --> S.P. Fan --> AF Fan (for the back of the case, exaust)

S.P. Fan pushing air through the radiator, and it's pulled out by another S.P. Fan, and then again pulled out of the case by an AF Fan

 

or

 

S.P. Fan --> Radiator --> A.F. Fan --> AF Fan (for the back of the case, exaust)

S.P. Fan pushing air through the radiator, and it's pulled out by an A.F. Fan, and then again pulled out of the case by another AF Fan

 

Or should the fan for pulling air outside the case be a S.P. fan as well?

 

Thank you for your help.

Both should be pressure optimized fans of the same type.

Stacked pressure scales, CFM doesn't.

I haven't seen a 212 in a while, depending on how tightly packed the sink fins are it might not matter either way.

and sorry for placing this topic in watercooling. my mistake

Just use SP's all the way. The CFM difference isn't that bad, and SP fans have more use cases than SP's.

You should keep the fans matched,the lower performing one will die before MTBF.

Thank you "chos55555". That video answers exactly my question and solved my problem.

Thank you Linus for making that video at NCIX

Linus did a video saying, SP --> radiator --> AF  was the best config they got for their rads

A push-pull config on the Hyper 212 Evo is beyond unnecessary. The fins aren't that tightly packed, and the depth of the heatsink isn't much to worry about. I can try and take my side panel off and take some close-ups if you'd like. I have mine set as a "pull," due to hard drives being in the way for a push config.

@Johnny Grey

If it's not a big deal for u, please... do take of the sidepanel and show me some pics. I can estimate better if i have a real life picture of the cooler in the sistem.

 

Thank you all by the way, for being so helpful.
