What Noctua in front of a honeycomb grid ?

Post by ditche » Wed Apr 10, 2019 5:41 am

Hello guys,

I have 3 Noctua fans : an old NF-P12 3 pin, a new NF-F12 and a new NF-S12A.
I put the NF-F12 on the heatsink, can you tell me what is best for this honeycomb grid : the old NF-P12 (or a new NF-F12) or NF-S12A?

(Or buy a NF-A12x25, but the price is not the same.)

I know the story of static pressure and airflow, but I do not know what is best in this case.

Thank you. :D

Any of those will do if you use a duct so that the turbulent air coming off the blades has time to moderate before encountering the grill. I cannibalize loud fans to make 25 mm duct sections.
-My Main System-
Antec Solution SLK1600 Case, Corsair CX450M PS, i7-3770, ASUS P8Z77-V_LK, Kingston HyperX DDR3-1600 CL9 with XMP, Cooler Master Hyper 212, 1 PWM fan on duct to the rear of the chassis connected to CPU header.

Some things have turned around in our modern society. Long ago when
men would scream and flog the ground with sticks, it was called witchcraft.
Today, it's called golf.
