NH-U12A versus NH-U12S; question about RAM clearance
I was able to answer my own question by looking up matching builds on PCPartPicker. There are multiple examples that all show the RAM fitting next to the cooler with zero overhang. This one has the clearest photos I could find: https://pcpartpicker.com/b/xtnLrH (There is also one example in which the cooler does overhang the RAM modules, but it's because the builder rotated the cooler 180 degrees. The cooler is asymmetrical.) I hope this helps in case others have the same question in the future. More on reddit.com

u12a ram clearance on asus strix b650e-i
Greetings from Noctua! Since the NH-U12A has 100% RAM clearance, you will have no issues with RAM compatibility. Furthermore, we have not found any incompatibilities with the VRM heatsink at the rear. We do not think you will have to set the fan any higher than normal: ASUS ROG Strix B650E-I Gaming WIFI | Motherboard Compatibility | Noctua Compatibility Centre . More on reddit.com

With all of the extras out of the way, it’s time to focus on the Noctua NH-U12A chromax.black. The NH-U12A chromax.black, like every other Noctua cooler, is an award winner in its own right.

r/Noctua on Reddit: NH-U12A versus NH-U12S; question about RAM clearance
December 7, 2022 -

I'm building a new gaming PC and discovered that the Dark Rock Pro 4 cooler is physically incompatible with my RAM modules. I assume the NH-D15 would have the same issue. The RAM modules are 44mm tall. I'm using the TUF Z690-Plus Wifi D4 motherboard and a 12700K CPU.

I'm trying to decide between the NH-U12S and the NH-U12A coolers for this system. I don't plan on overclocking. My main concern is ensuring the cooler can actually physically fit. The RAM modules have RGB so I would prefer to avoid any overhang at all if possible. I would also like to be able to swap out the RAM in a few years without having to mess with the cooler.

Is there any difference in RAM clearance between the U12S and U12A? I see that the U12A is asymmetrical; will it fit without any RAM overhang? If anybody has experience with a similar build I'd really appreciate your input. Thanks!

As a rule of thumb, if the fan overhangs the RAM, the maximum CPU cooler height specification of the case must be at least the size of the fan plus the height of the RAM minus 7mm (accounting for the height of the socket and CPU).

Noctua NH-U12A Single Tower Cooler Review - Back2Gaming
March 17, 2021 - This combo allows the NH-U12A to perform at the level one would expect from a dual-tower like Noctua’s own NH-D15 but with only a single tower. This has been something I’ve been looking forward to and I can now finally see for myself how the single tower NH-U12A performs. Read on! 140mm class performance in 120mm size: 7 heatpipes, more surface area and a dual fan configuration with state-of-the-art NF-A12x25 fans allow the NH-U12A to rival many 140mm size coolers! Excellent case, RAM and PCIe compatibility: Fits most tower cases (158mm height), doesn’t overhang the RAM slots on LGA115x and AM4, doesn’t block the PCIe on most ATX and Micro-ATX motherboards.

I have a B450 Aorus mobo with HyperX ram and a fat 2060 occupying the first slot. Would this still fit? I'm probably being paranoid but I really like this coole...
