    Apologies, I misread the prior post about which size was needed.

    I have these fans (in both sizes) in several machines here; I can believe that they may not be quite as well behaved as the Noctuas noise-wise, but as part of the overall noise of a normal (water cooled) system there's nothing particularly untoward, at least to my 45yo ears.

    (I do also have Corsair MLs and Noctuas in service as well, so I'm not just bigging up the Arctics absent any other experience. I do really rate the Corsair MLs but I can't find an all-black non-RGB link for the Corsair MLs)

    Those are 140mm, where he specified 120 (although they do make smaller fans, and if there is room in the case larger fans will tend to be better.)

    The price is certainly better, but when I was looking at reviews and discussions there was a common note that the noise is not ideal, especially in the middle of the fan curve around 1000RPM.

    Thanks to you and @steelghost for the replies. The case does support up to three 140mm fans in the front, and the price of these Arctic brand fans is certainly a little easier to take. Does this "PWM sharing tech" they mention just mean that you can power two fans from one motherboard header? The motherboard in the system (ASUS Prime X670e Pro WiFi) has a total of four 4-pin headers for chassis fans (I'm assuming two of them are currently in use).

    PWM PST mean you can daisy chain as many fans as you want, motherboard fan header power out capabilities aside. The P-series are ~1.5W fans at max RPM and most motherboards max at 1A(12W) on the non-pump/AIO headers.

    Pay attention to which you buy, as the P-series come in multiple version(3 pin, PWM, PWM-PST and then CO options). If you want to daisy chain without a splitter, you want PST variants.

    My anecdata/rule of thumb, the P-series is within 10% of Noctua performance, are pleasant to use up to ~1000 RPM. After that, blade and motor noise become audible and they have a worse subjective noisiness curve than the Noctua's as you increase RPM.

    +1 for the Arctics. Ignoring cost I'm sure Noctua is better but for most people the P series is good enough especially in a situation like this where they're supplementing the existing cooling rather than building something from scratch with the goal of total silence. Anything as good or better than the acoustics of the existing fans will be pretty much indistinguishable.

    Bought a new 7800X3D setup myself in late November '23. My former i8700K + 2080 setup had reached the "would need total disassembly, a new case and PSU to upgrade" stage of its existence, and at that, the case would have been big enough for something like a 4070 at most, so I decided to splash out a bit.

    -MSI B650-M Pro (discounted at the retailer)
    -be quiet ! Dark Rock 4 HSF
    -Corsair DDR5 5600 (32GB)
    -Corsair RM1000x PSU
    -Thermaltake Tower 200
    -Asus TUF 4090
    -Transplanted my SSDs and some other parts from the previous build
    -Got an educational discount on an Alienware OLED monitor too

    New setup is a bit of a monster, and initially surprisingly little fun to benchmark out of the box - older stuff like 3DMark 2005/06 doesn't even strain it enough to spin up the GPU fans; it needs something like FurMark or the Unigine Superposition benchmark to warm it up. The Tower 200 case is pretty striking visually too; PCs have come a long way from the beige boxes of the 1990s - to my (rather older) eyes, it doesn't really look like a PC at all if there wasn't keyboard in front of it.

    I guess I've gotta take a look at this case. ;-)

    A lot of cases are strange to me now, though. I was cool with moving the PSU to the bottom, that just made sense. but why put a big ol' cage (however porous) around the PSU, extending to the front of the case, to isolate that area from the rest of the case? To force cable management somehow?

    I believe the intent is to set up a separate cooling zone, since PSUs normally blow air in only one direction. By isolating that compartment, it takes care of itself however it wants to, without impacting the direction of airflow in the rest of the case.

    I don't actually know that, I've just inferred it from seeing lots of cases over the years.

    That, and a lot of cases hide 2.5 inch drive cages down there as well.

    I think it was largely aesthetics, to hide the cabling. Just my impression though. I doubt that airflow had a lot to do with it.

    In the case of the Tower 200, it's probably all of those things - isolation, aesthetics & cabling, and cooling. As Steelghost says, the PSU is seperate from all the other components with its own fans and "air supply". The Tower 200 has vents everywhere, and it pulls in air pretty briskly at the sides, including the rear. The vent is vertically straight up out of the top.
