Amazing price and performance!
The Thermalright Peerless Assassin 120 SE is an amazing cooler and brought my PC from hitting 70con on high load on my old cooler to now only maxing out at 46c and my idle temps are at 19c. It runs surprisingly quiet! It fits well in my PC which is on the smaller side of cases but definitely make sure that it will fit in your case. Installation is pretty easy just make sure to screw in both one at a time so you aren't only screwing in one side of the cooler. Installing the fans is also very easy they come with fan clips which clip on well and the fans can be daisy-chained and the wires are pretty well hidden when installed.

Quiet and cool
The fan is quiet and amazing. The SE Black model looks amazing behind the glass. I was worried about it fitting in the case but it was no problem. My only complaint is that the thermal paste it came with was dried up and the tube barely had any in it to begin with. Good thing I had a backup thermal paste. For the price and quality of air cooler though I'm not complaining.

Great Product
Have not stress tested, but for my Ryzen 7 3700x itโs working great! Just make sure about cooler height as it is on the taller side. The extended padding on the fan edges works well, had to mount the one fan a bit higher to clear my memory and the fan still mounted against the heatsink on the pad so it remains nice and quiet

Keep it cool!
I purchased this for my new build rather than use the hunk of aluminum that came with my pre-built PC. It seemed to have pretty high marks and was easy to install, came with everything needed depending on which board and CPU you have. It comes with two fans, and I feel pretty secure in the knowledge that it will keep my CPU and PC running cool. It doesn't have RGB lighting, as this is not a gamer, but works in my music studio. I didn't feel I need the extra flash!

Excellent air cooler
Beautiful in appearance, not very heavy, and does a fantastic job with temperatures. In winter, a 5800XT would go from low 20s to mid-70s. Generally, the fans don't have to spin at full speed, which is rather loud. A maximum of 60% leads to a balance of cooling and noise. Installation can be tricky. After installing the bracket and applying thermal paste, align the spring-loaded screws of the tower with those on the bracket, then they should catch. Tighten a little on one side, then the other. Repeat till both screws are tight. Also, the tower is asymmetrical, or shifted to one side, for clearance on the top and bottom. Test first to get the best placement for your case and GPU.

Massive Cooler that works well
Massssive cooler, like really big compared to a typical processor fan. This thing is a sexy beast, and It is one of the best rated Coolers for the price bracket, and suggested by ChatGPT if you ask what cooler you should get. Now, my PC no longer turns into a space heater when I play demanding games. ONE NOTE: If your RAM is close to your processor, then one of the 2 fans you attach may not sit 100% properly. However, you can still attach it, but it will sit above your RAM and instead of sitting like the picture, one of the fans will be raised because it has to be adjusted to sit above the RAM sticks. There is no problem with that, but some may not like it esthetically.

Bulky powerhouse
Installation was a little difficult because I didn't have as much room as I thought in my case but after some wiggling around I got everything to fit nice and snug. The directions it comes with are pretty terrible so if you aren't sure watch a video. There were tons of installation videos on YouTube. So far it has kept my pc running super cool even under heavy loads. I would definitely buy it again.
