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!

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.

Decent Cooler
I really like the design and the performance of this CPU cooler. The reason I give 4 stars is the fact that the tower is slightly offset. For the price it works very well tho. Tested with two CPUs (12100 and 12600). Both performing great around 60C (i3) and 67C (i5) in Cinebench.

Works well and fixed my overheating problems
Apparently my 10 year old CPU water cooler was no longer functioning well as my computer was shutting down due to overheating. This cooler was an easy replacement on my LGA1150 as it used the same backing plate and fan connector. (I didn't hook up the led lights) According to HWMonitor, my CPU core temperatures now rarely go above 95F and my system no longer throttles under heavy load. It does come with a syringe of thermal paste and hardware that should work with all the socket types listed. It is tall so check the clearance in your case against the specs given.

Best budget CPU cooler you would ever need.
Decided I needed a cheap cpu cooler because the stock AMD cooler wasn’t cutting with for my cpu once I installed this new cooler it was perfect, temps were low and not spiking up like before now I don’t have to worry about my system getting hot it’s cool all the time now. Great CPU cooler for the price and beautiful rgb, makes my system perfect. Would recommend

Recommend it for budget builds
Very quiet and fits perfectly with every ram slot in my case. Easy to install and the build quality is pretty decent. Performance is great and I recommend it. Great for the price.
