[SOLVED] high pressure 80mm fans

[hardwarenuts0]

I’m looking for 80mm fans to replace the stock ones in my NAS. The stock ones are

48.6-5-64.1 CFM
5.8 - 12.5 mmH2O
39.5-48.0 dB(A)

I’ve been unable to further narrow it down due to ambiguous labeling.

I tried a Noctua 80mm fan (Noctua NF-A8 PWM), and while it theoretically has a large CFM, the static pressure is too low.

55.5 CFM
2.37 mmH2O
17.7 dB(A)

Sucking in air through all the hard drive cages is apparently a little too tough. I have yet to systematically measure the system temp, but it is warmer.

So I have looking for a 80mm fan with the following characteristics:

Around 50 CFM
Around 5-7 mmH2O
Under 38 dB(A)

Would a fan in the link work: https://www.amazon.com/DELTA-AFB082...sure+fan&qid=1551380535&s=electronics&sr=1-17

According to spec, it runs 46.6 cfm @ 0.267" WG, so roughly 46.6cfm @ 6.7-6.9 mmH2O.
