Cheap and reliable!
This cpu fan is perfect and cheap. It was easy to install, and if you're using AM5, you only need to install the front brackets. At full speed, this fan is silent and cools very well. Im using a ryzen 5 9600x and under peak loads it doesnt even reach the 80s. It is a overall cool cpu though so your results may vary. The RGB is great and for its price, its perfect.

Hesitant to buy but, it does VERY well.
The Thermalright Assassin King 120 SE, is a great CPU air cooler. One thing to note is that I have 9 fans in the case so cooling isn't an issue for me. Performance is on par with the more expensive and overpriced options out there especially if you enable smart fan curve in your BIOS (if available). It's Size is small enough to fit most cases and the Color is white which blends perfectly with my all white build. Mountability is easy and installation is a snap making for a quick build to play time. As far as noise, I've read reviews about others like the peerless assassin and this one saying that it's too loud but I can assure that it is not. Nothing in this world is whisper quite but this... this does it for me. With a Yeston AMD RX 7800 XT and a Ryzen 7 7700x with A-XMP Profile set to run the ram at it's advertised and required 5200 MT/s speed, it keeps the CPU cool while editing/rendering videos at roughly 54-55C occasionally jumping up to 66-70C but that's normal for the type of CPU. I'd recommend grabbing this!

Fantastic Value Cooler
I got this cooler to save money, and overall, I’m very happy with it. For the price, it offers a really compelling mix of performance, low noise, and solid build quality in a compact package. The variable speed is very helpful, it handles moderate to high loads frpm my 7600x well. Despite being budget-friendly, the cooler feels solid, mounting hardware is decent. If you’re looking for a nice budget air cooler that punches way above its price, this is a smart buy. It’s not going to beat high-end dual-tower coolers or AIO in extreme overclocking scenarios, but for most general gaming/work builds, it's more than sufficient, quiet, and reliable. Highly recommend it for budget-conscious builders who still care about performance and looks.

An excellent option if you're on a budget but want an efficient air cooler for you PC
I bought this as I was building a gaming / photo editing PC. I'm currently using it to cool an Intel i7 8700 and so far, I don't have any complaints. It runs cool and is whisper quiet. The instructions are basic, but clear enough to understand. Mounting was slightly tricky, but I eventually got it. The color and design works will as I went with a "blacked out" PC look and didn't need RGB. The size is good enough, though it may depend on your specific case. I'm using it in a Cooler Master Elite 301 Lite case and the top barely had enough clearance to ensure that it wouldn't interfere with the glass panel. On the plus side, it also doesn't interfere with the memory slots, so I have easy access to all four slots on my motherboard. Overall I would highly recommend this cooler if you're looking for a great yet affordable CPU cooler for your next build

It does not sync well
Works fine I'm using it on a R5 5600x and it's not loud it keeps cool. Very easy to install and mount. It does not move around and fits snug on the cooler. The only downside is the rgb kinda sucks.

Great (“better than stock!”) budget cooler for older OR newer Intel builds.
Cools better than stock on every platform tested, using “X” pattern thermal paste. Used on i7 CPUs, nice QUIET fan with spring mount- easy to pop off to clean. Hard to beat price point for value. Sharp style & color ensure this will not clash with newer motherboard aesthetics. Zero issues or DOA units Across several builds. Backplate helps brace mobowell. Color options in mounting hardware are a nice touch. Will be using more of these.

İ3 12100f işlemci kullanıyorum 58w intel sitesindeki bilgiye göre. HWMonitor ile değerleri kontrol ettim. Stok fan ile genelde oyunlarda en fazla 75-78 derece arasını görüyordum. Capcut Video Editor ile AV1 codec ile çıktı alırken (bu codec işlemciyi fazla kullanıyor) ve Cinebench R23 programının ikisinde de en fazla 82 dereceyi gördüm. Fan sesi bayağı arttı +2500rpm de. Duyuluyor. Thermalright Assassin King 120 SE soğutucuda ise üstteki yazdığım Capcut AV1 codec ile çıktı alırken ve Cinebench R23 programının ikisinde de en fazla 62 dereceyi gördüm. Ayrıca 1030-1050 rpm i geçmedi. Boşta ise 300-400 rpm arasında dönüyor. ARGB olanı değil düz gri renkli geldi. Açıkcası pek de önemli değil bu. Fan sesi neredeyse duyulmuyor ve çok iyi derecede soğutuyor. Noctua NH-U12S Redux alma niyetim varken kasa boyutunu 1 cm aşıyordu. Vazgeçtim bunu aldım. İyiki de satın almışım. Birbirine yakın soğutucular. Kutu içerisinden Thermalright TF4 termal macun çıktı. Ama MX-4 Termal macun ile kullandım. Bu değerler ona göre. *Bu arada H610M Bomber DDR4 anakart ile 2 adet ram kullanıyorum. Ram soğutucuları ram boyutunu 1.5-2 cm artırıyor. İşlemciye yakın olan ram e çarpıyor ve yerine oturmuyor soğutucu. Hasar verir o yüzden ramin soğutucusunu çıkardım. O şekilde kullanıyorum. Biri soğutuculu diğeri soğutucusuz. Kargonun gelmesi uzun sürüyor. Los Angeles'tan geliyor. 18 günü buldu gelmesi. Kutu içerisinden AM4, LGA 1200 ve LGA 1700 uyumlu montaj parçaları çıkıyor. 660 + depozito ile 939,74 TLye mal oldu bana. Fiyatına değer. Sessizlik ve soğutması çok iyi. Fanın yanında PWM kablosu da mevcut. Bütçesi olan ve soğutucu arayan anakartı ile uyumlu ise tavsiye ediyorum.

Cooling Performance: This cooler has significantly improved my CPU temperatures. While playing CPU-intensive games like Fortnite, my temps now hover around 50°C, which is a massive improvement over my previous cooler. Even during extended gaming sessions, the temperatures remain consistent and well within a safe range. Design and Build Quality: The white finish and ARGB lighting add a sleek aesthetic to my build. It looks incredible inside my case and matches perfectly with my overall white-themed setup. The build quality feels premium, and the cooler is sturdy and well-made. Installation: Installing the cooler was kind of annoying with screw lifters things were annoying to get on but other than that the process was easy Noise Levels: Despite the excellent cooling performance, the fan is surprisingly quiet. Even under load, it’s barely noticeable, which is great for maintaining an immersive gaming experience.
