Heart set on the noctua high rpm ippc fans, just need to make sure they won't fry anything

cleric_warlock · May 22

I'm looking at the NF-A14 industrialPPC-3000 PWM (12 V, 0.55 A, 6.6 W) and NF-F12 industrialPPC-3000 PWM (12 V, 0.3 A, 3.6 W) to replace all of the case/radiator fans I have of the appropriate sizes. I'm routing 4 of the 140's and 1 of the 120's through the corsair commander pro (all of the case fans). I'm pretty sure everything going through the controller should be fine, but want to verify that everything I'm trying to route through my aio coolers won't be a problem. I have this version of the 3090 ti https://www.newegg.com/gigabyte-geforce-rtx-3090-ti-gv-n309taorusx-w-24gd/p/N82E16814932510?Item=N82E16814932510 with a built in 360 mm water cooler that I will use 3 of the 120's on and the arctic liquid freezer ii 420 that I will use 3 of the 140's on.

The 3090 ti + cooler is only connected to my system via its pcie slot and the cables from the psu that power it, its radiator fans do not make use of any mobo headers. My power supply is 1600W and my z690 asus rog maximus hero mobo is receiving the full supply of power that it can physically support. The arctic cpu aio cooler I have is wired to the W_PUMP+ header that provides 3 A max current and 36 W max power. When I lay out the numbers like this, it seems like everything should be fine, but I don't want to make any expensive mistakes. All insights welcome!

You should use those industrustrial fans for the radiator, rather than using them for case cooling.

I have one, and won't use these fans for case cooling only for radiators

Also be aware that above 2000rpm they're pretty noisy

They're labelled "industrial" fans for a reason. They're obscenely loud at 3000rpm.

Just get regular A14's and the A12's for the radiator.

They are pretty loud.. you would probably hate your computer after you are done.

I'm well aware of how loud they can be and am prepared to spend time designing fan curves to mitigate that. The only time i'm even going to let them go above 1700-2000 rpm is when my temps hit 80ºC and i need to dump heat fast. Seems like i'm probably ok on the power front.
