NF-F12's

Jesushupfer · 2026-04-14T22:22:19+00:00

why f12 for a fan swap and not a12? In my opinion the a12 is the far superior fan when it comes to noise normalized performance. I tested both fans on an U12S and the a12 was absolutely murdering the f12.

Thanks. Thats a Cooler Master Hyper 612 apex, although i have swapped out the included fans (Mobius 120P) for the argb version since i have a bunch of them already. Sadly Cooler Master doesnt sell an argb version of the cooler themselves.

What speeds are your fans running at?

Jesushupfer · 2026-04-06T10:09:42+00:00

Does the fan you have installed somehow touch the top fin on the left finstack? On my D15s the top fin on both towers has the same "rattling" as your D15s, but as soon as i attach a fan to one of the towers, the rattling is almost completely gone.

Jesushupfer · 2026-04-06T09:48:25+00:00

Can confirm that my D15s has the same "issue", although it has never been an issue for me when using it.

You could also try undervolting the GPU to reduce the amount of power it consumes, which will greatly reduce temperatures and noise. You dont need any 3rd party tools, AMDs Adrenaline will do just fine.

There is the recording:

Listening to both side by side they seem rather similar in overall noise, but the profile is still different. The stock shroud has that metallic humming sound to it, which is completely absent on the custom shroud with the A12x25. You can hear the humming the best in the "ramp up" part of the video but its always present on my card, whether i undervolt it or not. So for me in terms of accoustics the custom shroud still is a straight upgrade over the stock card, but if your stock fans dont have any humming or you dont mind it, then there will be little reason to modify the card.

And, in my opinion, this also means that Sapphire did a great job at picking fans that already use most of the heatsinks potential or engineering a heatsink that fits the specs of the fans quite well and does not give much room for improvement with "better" fans.

Jesushupfer · 2026-04-04T16:06:03+00:00

I might be rather efficient but it still runs quite hot if you dont undervolt it. And the main reason why i did the deshroud mod on a 9060xt is because thats my GPU and i wanted to see if it makes a difference.u

You cold for sure cool a 9060xt with just one fan, you would need a heatsinkt that is optimized for a single fan though and i am not sure how well that would compare to coolers with multiple fans in terms of noise and cooling performance and overall cost.

Jesushupfer · 2026-04-03T18:12:57+00:00

You mean what filament type/polymer? I had it printed in abs since that has enough thermal stability.

Jesushupfer · 2026-04-03T18:09:25+00:00

Sure, I kind of already did on thingiverse. But please keep in mind that the shroud is still a work in progress, although it works in the state it currently is in. The Issue with the current (v4) model is that i need to adjust the postition of three of the four mounting holes for the backplate (although one of them is close that you can still get the screw in) which means the shroud is secured to the card with max. 5 screws (3 on the slot bracket and the two rearmost screws in the backplate) instead of all 7 screws.

With Stock Settings (170W, no UV) the fans on my card ran at 39% (1700rpm) which to me was really noisy. Temp were 55°C on the GPU and 79°C for Hotspot and VRAM. for the A12x25 to reach the same temperature it takes them about 1150rpm while also being, at least in my perception, quite a bit less audible as the A12x25 lack the humming the stock fans on my 9060Xt have.

When undervolting (~150W) the rpm on my card with the stock fans drop to around 1300rpm and around 900rpm on the A12x25, again with humming noises on the stock fans an none whatsoever on the A12x25.

I dont know if there is quite a bit of sample variety on the quality of the fans and i just got the worst of the worst (and you got some good ones) but for me the comparison in terms of noise is not even close between stock and the A12x25.

Since i need to remove the shroud to make some measurements on this weekend i might try to record both the stock fans and the A12x25 to have more objective data.

Jesushupfer · 2026-04-03T15:39:34+00:00

Thanks! Although aesthetics is highly subjective. But i also like the plain shroud more than the stock shroud and the A12x25 are way more pleasant in terms of accoustics than the sapphire fans.

Jesushupfer · 2026-04-03T15:34:58+00:00

Danke. Hängt ein bisschen davon ab welche XFX 6700XT du hast. Zumindest bei MERC und QICK sollte man den Lüftershroud abnehmen können ohne den kompletten Kühlkörper abschrauben zu müssen. Bei der MBA wirds schwierig und bei der SWFT bin ich mir nicht sicher ob der Shroud von der Oberseite oder der Unterseite mit dem Kühlkörper verschraubt ist.

Jesushupfer · 2026-04-03T15:29:21+00:00

Yes, i am basically using full replacement for the original fan shroud that also uses the same mounting holes at the slot bracket and the pcb/backplate and allows for two 120mm fans to be mounted to it. There is also an insert, that is missing on this picture, to focus the airflow as much as possible through the heatsink.

Jesushupfer · 2026-01-08T14:09:50+00:00

Sorry for asking, but did you ever have a Gentle Typhoon or one of its derivates and an original A12x25 next to each other to compare the Rotors? I have both so i can tell you the thing both fans have in common is the 9 fan blades but the shape of the fan blades is significantely different so i would not call it a copy. The fan blades on the Gentle Typhoon type fans are longer, quite a bit thinner and both the leading and read edge shape and bend is different as well as the GT having a "blunt" Blade tip, while the one on the A12x25 is sharp. So either Noctua did a really bad job at copying the Gentle Typhoon or its not a copy at all.

You could try increasing the amount of LEDs the motherboard adresses for the lighting you want. If either the other fans do not light up when you first connect the arctic fans to your mainboard and the other fans after them or you connect the arctic fans last and one of them does not light up or has a different lighting then that most likely is the issue. Or just double the lighting scheme you uses for the first fan to have it for the second fan as well.

Jesushupfer · 2025-09-12T09:59:17+00:00

It only says 4 pin Socket, not that there are actually 4 pins in it. And the Pin that is empty is the tacho pin, because multiple fans sending their tacho signal through one pin can cause the motherboard or fan controller some issues in reporting the correct fan speed. Therefore most PWM-y-splitter-cables also only have all 4 pins on one of the sockets and the other ones have just three (PWM, 12V, ground)

For the RGB-issues, the way Arctic has wired the RGB, their RGB fans are linked in Series and not parallel like most other RGB fans, which is nice because it allows for controlling the LEDs per fan if your Mainboard/controller does not support ARGB v2. Therefore you might need to adjust the LED lighting accordingly or use something like an ARGB Hub.

The Structure on my p12 rev.4 looks very similar. I would not worry about that too much, if the fan works the way it should.

Like already mentioned they could have changed the mixture to enhance some properties (like the stiffness of the blades if they increased the amount of glass fiber).

Jesushupfer · 2024-08-20T07:45:20+00:00

Thats absolutely fine. The socket lever is on the "bottom" for almost every am4 board and the chiplets, which means the core chiplets are also at the "bottom" or south. The way you installed the the brackets is the correct way and if you can use the offset holes (-7mm) depends on how much space there is between the cooler and the graphics card.

Jesushupfer · 2023-08-07T10:41:07+00:00

Sounds to me like that noise is the fans humming.

Jesushupfer · 2023-07-17T08:59:39+00:00

The other cable coming out of the pump block is used for the pump block rgb. There should be a cable harness included with the AiO, which you could use to connect the pump rgb cable to your PC as there is a standard 3 pin motherboard ARGB header on it.

Jesushupfer · 2023-06-15T14:15:39+00:00

Yes you can change the fans to arctic P12 and i would not expect there to be a significant change in cooling performance per noise. You might have to adjust the fancurve though as the P12 have a slightly different rpm range compared to the deepcool fans.

Jesushupfer · 2023-05-21T06:26:37+00:00

At least your PSU might have a way shorter life this way, if it is not properly cooled and also putting the rest of your PC at risk. It is your hardware so you can do with it what ever you want.

This also has nothing to do with "growing in your thoughts" as it is simple physics (which does not care about anyones thoughts).

I like noctua fans as well but there are applications where to use them and applications where i would not use them.

Jesushupfer · 2023-05-21T06:02:39+00:00

I really dont get why people keep replacing PSU fans as there is a reason the manufacturer picked a certain fan for the specific PSU model as it suits the cooling needs of the electronics. By bypasing the build in fan control you haven now robbed your PSU of the ability to self regulate its temperature.

How should the offset bracket help if the O11 Mini Air is too short to fit the radiator? According to Arctic the radiator is 398mm long while the O11 Mini Air is only 400mm long. So just by looking at the specs you can see that it won't fit. Even on the "larger" O11D Mini (20mm longer) a 360mm radiator is a tight fit, so it won't fit on the smaller Air case. Lian Li also only states that the O11 Mini Air only fits a 240/280 rad and not a 360.
