Honestly Amazing
Short Version: It’s really really good and you should buy one, because I feel like I stole it at this price.The Full Story: I bought this Noctua to replace an (8yr) old water cooling unit. I have never done this before. Fortunately the Noctua comes with instructions that are clear and easy to understand and the cooler has thermal paste already applied in a very pleasing pattern. Thanks for that as it clears up the age old question of “how should I apply the paste? In a pea shaped amount, or should I spread it out or should I put multiple blobs?” Noctua did it for me, awesome. I switched off my pc, and waited for only 10mins, before removing the old cooler. This meant the old paste was still moist and therefore easier to remove. The new cooler had all the brackets and spacers required to fit it to my motherboard and CPU, with clear instructions how to fit them. The only sacrifice I had to make was removing one of my side case fans, as the fan protruded in to the case about 20cm, and the side door would not fit. I still have one more side case fan, two on top and one on front. So I would urge you to check the measurement of the cooler, and check you have the clearance. As for performance, well I am amazed that an air cooler can perform this well. At idle temps have dropped by 20c and fan speeds halved at that temp to 30%. Under load temp hasn’t gone above 60c and 70% fan speed. I think my case may have been designed for air flow, and its running great. This is one of those rare moments when you buy something and it’s not just perfect, but it performs way better than you could’ve possibly imagined and it was a lot cheaper than you imagined too. I would say I am speechless, but I am clearly not, so I will say that I could wax lyrical about this Noctua cooler, but I will finish here: an excellent product and well worth the money.

Noctua U12S Redux – A solid choice of cooler!
It’s an excellent CPU cooler for £44, it keeps my i5 12500 nice and cool whilst remaining quiet (much quieter than a stock intel cooler), it could probably handle a bit more too! Mounting it was also fairly straightforward, so no complaints here!

Backplate design change
Very good quality cooler by Noctua, perfect for my new i5 11400 build. Allows it to boost to maximum speed on heavy loads and is still super quiet. Only slight quibble is the redesign of it backplate. Far more fidly and time consuming to assemble especially for novice builders, Noctua lost points on that. Overall though very solid component for the price point.

Purchased this with the optional second fan as an upgrade from the stock cooler that comes with my 5600.I had been looking at purchasing a Noctua cooler, specifically the NH-U12A or the NH-U12S but could not justify pulling the trigger on a $100+ cooler when the stock cooler was doing a good enough job. But then I found this cooler with basically the same performance for half the price, and I knew I had to get it.PROS:-AMAZING cooling! With the stock cooler, my CPU would get to 90+ degrees while performing a 10 minute Cinebench. With this cooler, it barely gets above 60 degrees while performing a 30 minute Cinebench test. While gaming, even under the most CPU stressing game I have (Dead Space Remake) it stays under 65 degrees with PBO enabled.-This thing is QUIET! Like I said, I had purchased the secondary fan for a push/pull configuration on my cooler and even with the second fan, this thing is silent. Really the only noise coming from my PC is from the GPU fans spinning up. Before, my PC was noisy with the stock cooler, but I didn’t realize HOW noisy it was until I put this one in.-You cannot overtighten this cooler because of the spring loaded screws on the cooler-Comes with Noctua thermal paste pre applied, so you do not have to worry about paste, but get some just in case. Arctic mx-4 is $5 extraCONS:-It is tough to get the mounting hardware on without help. I managed to do it but it would be 100x easier with someone helping, or by removing the MOBO from the case. But I was lazy and didn’t want to deal with that. Plus, some of the standoffs for my board are under where the fans end up sitting, so I still would have had issues with it.-Some people have had issues with motherboard compatibility, but this could be user error. I use a Gigabyte B550M DS3H and had no issues. This cooler uses the backplate that came with the board for AM4. Intel uses the included backplate.-The threads for the screws are on the mounting hardware, and when you loosen the screws on the cooler, they are not free of the screws on the mounting hardware, keeping you from turning the cooler to break the seal from the thermal paste. Since this comes with Noctua paste pre applied, good luck getting this off without a fight.-Attaching the fans is hard as hell, especially if you do it in your case. I found that doing the secondary fan (if you buy one) first, then the front fan is WAY easier than doing it the other way. And the fans might block standoff screws if you put them on outside of the case.I highly recommend this cooler, and its good to see that the Noctua name holds up even on a more budget option.

I bought this because I was hitting peak temperatures of 82c on my Ryzen 5 5600x under full load with the stock cooler on stock bios config for the cpu.I chose this unit because I gad a great experience previously with the NH-u12P on my old core i7 920 and decided to stick to a brand I know even if it cost a bit more than the competing deepcool and cooler master units. I definitely don’t regret this decision. Core Tempuratures with the Noctua dropped to 55c under full load. A pretty substantial drop. As a bonus, the better thermals allow the CPU to boost better: my Cinebench scores went up from 10600 to 11200.Pros:-Easy and very solid installation/mounting process and overall setup. Easily the best in the business.-Quieter than the stock Wraith cooler even at full fan speed. The Noctua fan doesn’t even end up spinning at max rpm under the stock fan speed curve of the motherboard and temps are still excellent.-27c temp drop for my own personal setup under full load.-Noctua build quality and performance for a more reasonable price.Cons:-Still expensive compared to the Deepcool Gammaxx 400 and Cooler Master Hyper 212 for likely similar performance. You definitely pay premium for the better mounting system and brand recognition.-The redux fan is quiet but still noisier and not as efficient as the regular Noctua fans.

Sitôt arrivé sitôt posé ce ventirad Noctura a été monté en dépannage le temps du retour d’un système watercooling défectueux. Il remplace très facilement le ventirad d’origine de mon processeur AMD qui était à la peine lors de cession gaming un peu poussé. La différence est flagrante entre le ventirad d’origine et ce noctua qui reste beaucoup plus efficace et qui permet de gagner presque 17 degrés (!) ,en session de gaming en silence par rapport au ventirad d’origine AMD. Très bon rapport qualité prix ce ventirad noctura est très qualitatif. Je recommande !
