i have 2 different 120mm(total X6) fan from silverstone in my silverstone build, one are 1800 RPM 63 cfm and 2.4mmH2O the other one is 2500 RPM  100 CFM 4.66mmH2O
i want to do push pull for my aio(IceMyst 360) but i don't know which one i must use for push and which for pull.
the 2500RPM i must set for push and 1800RPM for pull?or
1800rpm for push and 2500rpm for pull?

I would use the stronger one for push, weaker one for pull.
