Hello everyone!

I have this issue where I cannot put both fans in push pull set up for my corsair H80i v2, I can only fit one but I think temps of my CPU get quite high whenever under load. I have a clearance of 1.6cm so I think i can fit a 120mm x 15mm, I have done some search and i came up with noctua nf-a12x15 pwm. If I set that as pull, would it improve my CPU temps? Any suggestions are appreciated. Thanks!

PUSH:
Corsair SP120L

Fan Airflow
70.69 CFM

Fan Static Pressure
4.65 mm-H2O

Fan Speed
2435 RPM


PULL:
Noctua nf-a12x15
Fan Airflow
55.4 CFM

Fan Static Pressure
1.53 mm-H2O

Fan Speed
1850 RPM
 
Solution
More often than not, you're limited by the radiator/fin density opposed to the fans themselves. The differing airflow between push/pull isn't going to be ideal - but it's still going to be better than the single fan*
I assume the H80i V2 *needs push/pull, as I've no idea why they'd ship a 120mm AIO with a native push/pull setup to begin with.

Unfortunately nobody seems to have benchmarked with only a single fan to verify this.

Where is your clearance issue that you cannot fit the dual stop fans in push/pull? Could you relocate the AIO to another fan mounting in the case?

I think we should take a step back and see what CPU you are using and whether it is overclocked or stock speeds?

120mm AIOs just don't have the capacity to keep up with higher-end CPUs with overclocks. Cooling (air, liquid or even LN2) all depends on how many watts a component produces vs. how well a cooler can expel that heat.

AIOs also use budget components: cheap aluminum radiators, small tubing diameters and low volume pumps. You'd likely need far more airflow or coolant flow - or both - in order to have that cooler perform very well.
