NOCTUA NH-U12S Redux CPU Cooler 1x 120mm Fan, 158mm Clearance, Support Intel LGA1851, LGA1700, LGA1200, LGA1156, LGA1155, LGA1151, LGA1150 and AMD AM5, AM4

I'm always a bit wary of fan setups that claim to work on competing CPU manufacturers, but someone was awake in the design room for this. Instructions are clear, installation is near instant, and the included thermal paste reduces fuss and mess when installing.

It's Noctua, so it's near silent - perfect for my media centre build, even under heavy gaming load.

Maaaan...what a beast of a fan! But what poor instructions. Be prepared to figure it out on your own.
Once you got it, it's magnificent. Maaaan...what a beast of a fan! But what poor instructions. Be prepared to figure it out on your own.

Installed it on a 5800x3d keeps it cool with no throttling, silent at idle minimal noise under load (drowned out by case and GPU fans). Easy to install and remove too.

Used to replace faulty AIO Cooler.
Kit had had all required parts, and clear, easy to follow instructions.
Performs very well in my application I7 - 7700k Used to replace faulty AIO Cooler.

I have built close to 30 PC's now for clients and friends using this cooler, it easily reigns supreme. Compatible with literally anything, comes with good quality thermal paste, fits majority of cases (mAtX-eATX), 6 year warranty, super reliable and quiet, great temps even on hot CPU's like the 13700K. My only complaint is that it has become pricey, especially since there are now a deluge of competitors for much cheaper. I will say that this fan is more often than not cheaper at ComputerLounge, but PBTech usually has stock on hand.

Purchased this for a AMD 7700.

It works well, but under high load, it can feel a bit noisy. My fault for not getting something bigger, but PBTech's stock was limiting my choice at the time.
It is quieter than a factory cooler that is certain.

High load = benchmarks, compiling, encoding videos, and processing photos.
For gaming, normal web surfing, and just general usage, PC is completely silent.

As far as temps go, I don't think it matters for most users, it keeps the CPU cool enough, never hitting the thermal limits.
If you want to overclock, then you will hit a wall faster than with a bigger cooler.

Noctua themselves have a cheaper NH-U12 option, which pretty much performs the same, this was on sale for almost the same price and was all black so went with it to match my build better.

It able to cool my Ryzen 5 2600 from 50C to 30 on idle, (used to be on stock fan)with my new CPU Ryzen 7 5700G it manage to keep temp around 48C on Idle It able to cool my Ryzen 5 2600 from 50C to 30 on idle, (used to be on stock fan)with my new CPU Ryzen 7 5700G it manage to keep temp around 48C on Idle

Nice little cooler that fits in a lot of cases with 158mm clearance. I like the black colour vs that usual Noctua brown. Nice little cooler that fits in a lot of cases with 158mm clearance. I like the black colour vs that usual Noctua brown.

I originally bought a CPU cooler and took it back as I had trouble installing it to the motherboard, the guy was super helpful and I ended up buying this CPU cooler which has been great. I can run anything I like with minimal temps, and it is super quiet.

accessories accessories accessories, it came with everything needed for the installation. a generous amount of thermal paste was included and the instructions were very straightforward. accessories accessories accessories, it came with everything needed for the installation. a generous amount of thermal paste was included and the instructions were very straightforward.

keeps temps around 30.C idle and 50/60.C under load without the need for more fans in case, I'm running two stock case fans keeps temps around 30.C idle and 50/60.C under load without the need for more fans in case, I'm running two stock case fans

I've used Noctua air coolers for many years, and once again they've not let me down. The stock cooler that was included with my 12th Gen i5 12500 was TERRIBLE, with idle temps around 44 degrees C. With this Noctua cooler, my CPU now idles at around 35 degrees and under full load barely goes beyond 54 degrees.

Installation was easy. The motherboard tray in my PC case has a cut-out under the CPU, so I didn't even need to dismantle the system to install this Noctua cooler. The best part was, the thermal compound is already applied to the cooler! I used ArctiClean (available from PB Tech) to remove the original thermal compound from my CPU bef...view more I've used Noctua air coolers for many years, and once again they've not let me down.

The best part was, the thermal compound is already applied to the cooler! I used ArctiClean (available from PB Tech) to remove the original thermal compound from my CPU before installation, though you can easily use normal isopropyl alcohol.

Noise wise, my CPU doesn't put out enough heat to max out the fan, so it runs very quietly (around 50~60% under full load).
