Fan placement on top of radiator

[TR10]

Would it be a good idea if you had the fans on top of the radiator when top mounted in the H440?
To be honest I'm only doing this for aesthetics and I need to know if performance will drop because of it.

Radiator: NZXT Kraken x61
Fans: Included FX V2
Case: NZXT H440

Thanks!

Not significantly. Whether on top or bottom, you will only see roughly a + or - of about 4-5 degrees.
