Style: AX120 Refined SE ARGB
This is without a doubt the BEST budget cpu cooler you can get. It SIGNIFICANTLY reduces temps compared to the factory wraith cooler. It just plain works. My temps are much more regulated, the fan is surprisingly quiet (BeQuiet! is still quieter). Looks great, actually matches my stock case fans almost perfectly. Very easy to install, just torque down the bolts in a cross pattern. Overall, fit and quality is great. Love this thing.

The Thermalright Assassin X120 R SE is so good. It's inexpensive, isn't the most difficult to mount on an AM4 system, is quiet, and keeps temperatures super low while the CPU is under load. I installed mine onto a B450 board with a 5600G. Compared to the Wraith Stealth during a Cinebench R23 benchmark, 10-minute run, temperatures on average were 19+ degrees C cooler with the Thermalright Assassin X. The ARGB fan is nice and sturdy and while only 8-leds, it's plenty bright and very quiet at idle speeds. For the cost, the performance is out of this world. I'm unsure how well this cooler will perform on higher TDP CPUs (5600G is only 65W), but I definitely recommend it. I took a couple of stars off for the mounting system/ease of install as the brackets are a tad fiddley. I highly recommend installing the cooler before you put the motherboard into your PC Case. As I was replacing my cooler, my mobo was already installed, so it was a bit more difficult than I liked. Other than that, this is a great product for those looking to get better temperatures for not a lot of money! A+++

Works great and matches all my other fans in my setup.

Replaced my AMD stock Wraith cooler with this for better fluid logistics in my case. Got a 3 pack of 120mm fans from the same company. The installation process takes a lot of close attention to exactly what's shown, since there's no words pointing out fine details like which way is up for the brackets, spacers, and fan clips. Still only took like 10 minutes but kinda annoying. The fan clips are nice and simplistic. Exactly enough to hold a fan firmly in place in either direction with no excessive screwing or manhandling your delicate computer's parts. Intel could learn from this. Heat pipes are quality, the fin stack is gorgeous and very effective. Got an extra .2ghz out of my overclock and my Temps still dropped by 15°C at max usage. (This was with all the fans I added, not just the cooler) For a $20 hunk of special metals, it's pretty outstanding the cooling you can get out of it. These horizontal fin stacks are something special Only complaint is that the pressure across the CPU from screwing it down is uneven, and you have to eyeball it pretty hard to get it even, maybe a level would help too. I wouldn't use it with a chip using the high side of its cooling capacity. A having 4 screws and a set height that the cooler sits that matches the socket would fix this with not much change to the design, and pressure distribution would be way better.

Cannot beat thermalright value. Cools very well for the cost and handles temperature amazingly for a single tower cooler. Performs great, looks could be better, but what would you expect out of a $16-17 CPU cooler? RGB colors can be easily changed and its average size means there are no size restriction issues.

Great cooler for am4 cpu. I just upgraded from a amd stock cooler. SO much more quiet. I did use my own paste on install.

I started hearing about Thermalright coolers on YouTube a few months ago. I wanted to replace a Wraith Prism cooler in an older computer I have so I decided to try one. Since it's not my primary computer I didn't want to spend very much. I shopped around and found the Assassin X120 Refined SE ARGB for less than $20! First of all, I don't know how they can sell these so cheap. Everything oozes quality, from the packaging, to the fan and heatsink itself. For $20 I expected it would just be thrown into a box with no padding. Wrong. It's packed very securely with lots of padding. Included are instructions and everything you need to install it, they even included the thermal paste! The instructions were very clear, making it one of the easiest CPU cooler installations I've ever done. The Assassin not only looks like it should be more than $20, it performs like it too. My idle temps (Ryzen 3700X) went from the 50ish degree range all the way down to 26-29 at 30% fan speed. Incredible performance for the money! The fan is also very nice with bright LEDs and isn't too loud. I'm blown away by this cooler. Thermalright has definitely won me over.
