Customer reviews
Customer Reviews, including Product Star Ratings, help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.

- Reviewed in the United Kingdom on 20 January 2024Style Name: Kraken EliteSize Name: 280mm BlackVerified PurchaseI was debating this cooler for my upgrade for a long time. Having upgraded my Cpu to a Ryzen 7 5800x I clearly needed an upgrade on my noisy 6 year old cooler master 240ml to have sufficient cooling.
Now this is expensive mostly because of the 60fps bright LCD screen on the pump. I almost convinced myself out of it thinking I couldn't justify over double the price of a lot of coolers for what a lot would see as a "gimmick". But when you see it in person it gives the most beautiful aesthetic. So for people in the same boat it is absolutely worth the extra money if you want a stunning and customisable aesthetic to your build.
Now this was actually relatively simple to install and they are plenty of videos on youtube if you do get stuck. But it's honestly not that hard (especially if you order the non RGB one like me). and it's also good that you can rotate the screen in the software after installation so you don't have to worry about mounting it the "correct" way or angle for the screen to be displayed right.
The unit is extremely quiet! to the point at first I didn't know if it was powered correctly when I first turned it on. Even under load it isn't very loud. Cooling performance is also very good, especially since my cpu is notorious for been a hot one in the Ryzen line of cpu's with temps between 40-55 when just browsing the internet and 55-70 degrees when playing graphically intensive games on ultra settings which is really impressive.
overall you are certainly getting your moneys worth with this cooler. Quiet, cool temperatures and aesthetically stunning with the large high quality 60fps LCD screen. Software to change the images/Gif's/readings is easy to use too.
This review is specifically for the 280ml non RGB Elite version of this cooler.

I’ve been running Baldurs Gate 3 at 4K all max settings and the CPU hasn’t gone above 50C so cooling is top notch.

- Reviewed in the United Kingdom on 16 February 2025Style Name: KrakenSize Name: 360mm BlackVerified PurchaseI've only been running this cooler for about a day, and so far I'm happy with how its running, the screen looks good on the AIO Pump, its all good. However, unfortunately whilst the build quality of the AIO itself is good, the radiator had quite a few visibly bent radiator fins, and whilst I'm not expecting much of a performance hit from it (if any), it was unpleasant to see for the amount of money spent that it had already been damaged, despite being in protective coverings inside the packaging.

5.0 out of 5 stars Excelente rendimiento y diseño premium
Style Name: Kraken Elite RGB 2024Size Name: 360mm WhiteVerified PurchaseEl NZXT Kraken Elite 360 RGB destaca por su excepcional capacidad de enfriamiento y su diseño elegante. Su pantalla LCD de 2.72" ofrece opciones de personalización visual atractivas. La instalación es sencilla y el funcionamiento es sorprendentemente silencioso, incluso bajo cargas intensas. Sin embargo, la necesidad de utilizar el software NZXT CAM para acceder a todas las funciones pueden ser consideraciones a tener en cuenta.

5.0 out of 5 stars Great product, splitter cable provided not compatible with Lian Li
Style Name: Kraken Elite RGBSize Name: 360mm BlackVerified PurchasePurchased with the lian li 24 and 8 pin. Ran out of ports for the kraken to set lcd screen to desired image. Writing this review to serve as a caution. If you plan on using more than the 2 ports provided by the MOBO get a splitter/hub. The provided NZXT splitter is not compatible with my lian li strimmer cable.

5.0 out of 5 stars Great cpu cooler! Easy to install!
Style Name: KrakenSize Name: 240mm BlackVerified PurchaseGot the NZXT Kraken 240 for my PC and it's been a game-changer. Keeps my CPU cool even during heavy gaming sessions, and the little LCD screen is pretty neat for showing temps or custom images. The installation was straightforward, and it looks slick in my case. Would definitely recommend if you're looking for solid cooling with a bit of flair. You can adjust the brightness of the lcd and it sounds pretty quiet so far. I was able to mount it easily but definitely mount the fans first before you fit it in. perfect fit.
