Those fans would be good if you're on a low fan budget, quiet af fans (as long as theyre not above 1000rpm lol)

I've had good luck with arctic, the standard cheap ones. The 5 pack can be a deal.

If you are willing to spend a bit more (ok, $22 per fan), the Silent Wings 3 High Speed PWM fans are really amazing. I'm running them at 50% for my front intake (UEFI shows around 1200 RPM, max is 2200 RPM) and they are almost inaudible in the NZXT H700. Excellent air flow too.

For a bit less ($13.50 per fan), you could opt for the Pure Wings 2 which top out at 1500 RPM. They are also barely audible at under 20dBA while maxed.

hi

this is my case: https://i.postimg.cc/mr8TBHgT/case.jpg

if want improve the airflow is a good idea tu put the fans only in the 1,2 place, one in the rear.

is the fan on place 3 for hard disk cooling? .... i have 1 hard disk and 1 ssd here....
