Keeping it Cool: Thermalright Peerless Assassin 120 SE CPU Air Cooler
Alright, so I just upgraded my CPU cooling game with the Thermalright Peerless Assassin 120 SE, and let me tell you, my computer feels like it's sipping iced tea on a hot day. I'm no tech genius, just a person tired of hearing their PC sound like a jet engine. First things first, the size โ it's not this towering monolith that swallows up your entire rig. At 120mm, it fits comfortably without turning your build into a spaceship. Plus, it doesn't look half bad. Sleek design, and the black coating gives it that "serious business" vibe. Installation was surprisingly painless. No need for a degree in engineering โ just slap it on and tighten a few screws. The instructions were like a buddy guiding me through it; I didn't feel like I needed to consult a tech dictionary. Now, the cooling power. This thing is like a ninja in the shadows โ quiet but deadly effective. My temps dropped like they just heard a great joke. Even under heavy loads, it's keeping its cool without sounding like a hurricane in my room. And trust me, I appreciate the silence. Build quality is top-notch. It feels robust and well-made, like it's ready to take on CPU heat with a vengeance. The heat pipes do their job, and the whole thing just screams reliability. Plus, it's compatible with a bunch of different sockets, so you're not limited in your CPU choices. The Peerless Assassin 120 SE is a game-changer for me. If you're tired of your PC sounding like it's about to take off, and you want reliable, efficient cooling without breaking the bank, this cooler is definitely worth a look. My computer's running cooler than a polar bear in a snowstorm, and I'm here for it.

Superb Value CPU Cooler...Just Buy It!
Needed a new cooler as my i7 kept overheating under load and shutting down the PC, usually at some crucial point! Looked at various solutions including water cooled but many were horrendously expensive and with the state of the world at the moment not having to spend a lot was a key consideration. I saw this model and read the reviews...it looked good, so out came the credit card and I purchased it. Now this is a big old boy and I was a bit concerned on arrival if it would actually all fit my case. But installation was a breeze and it fitted in perfectly. Great choice of mounts for Intel or AMD. Buy some of your own thermal paste though as the supplied paste wasnt great...too dry and wouldn't adhere to the CPU well. Once its mounted its cooling performance is very impressive with temperatures being halved under load. Plus its VERY quiet. What a bargain this cooler is. Its just superb. Forget your Noctuas or your fancy AIO's ...buy this beauty and save a packet!

Big Cooling, Small Price
I installed the Thermalright Peerless Assassin 120 SE in my rig, and itโs honestly one of the best bang-for-buck coolers Iโve used. Itโs got a dual-tower design with six heatpipes and two 120mm fans, and it handles heat like a champโeven with high-end CPUs. My temps dropped noticeably, and it stays whisper quiet unless Iโm pushing things hard. Installation was straightforward, and it fits nicely in my mid-tower case. Just make sure your RAM isnโt too tall, since the front fan sits close. Build quality feels solid, and it doesnโt look cheap either. For the price, this cooler punches way above its weight. If you want serious air cooling without spending a fortune, this oneโs a no-brainer

It's an overkill for a first build.
It's overkill performance for my Ryzen 5 5500, it's always stays right below 60 Celsius, will probably be enough tho for when I switch to Ryzen 7 5800x3D, Noise level is very low and if I ever want to switch to Intel in the future, there are extra specs left in the box for it.

Quiet, cool, unbeatable value for money
Ryzen 5700X doesn't get over 50C core temp under full load and it's not even trying. It's just 20C over case air temp. Water coolers stand aside, there's a new guy in town. Comes with a variety of mounts for different processors, decent thermal paste, and Y splitter so two fans can run off one CPU fan header. Build quality is excellent. My only observation is that one fan is a bit tight on Corsair Vengeance LPX DDR4 in an MSI MAG X570 tomahawk motherboard, but this could be alleviated by moving the fans to the other side of the cooler fins in my case (the fans can easily be moved either side of the cooler fins). It's sooo quiet... 100% recommended and would buy again.

Solid cooler, not pleasing to the eye.
It does what it is meant to, kept my i9 to a max temp of 74 degrees during AAA gaming. But it is not very attractive to look at. I feel the black one would have been more pleasing to the eye and compliment my build or the white one for a white build, in fact the standard one does not compliment any build unless you are going for industrial look. Really good cooler but spend the extra ยฃ10 and get the black one or white one.

The best of the best
The peerless assassin has achieved legendary status. I have used it for multiple builds for high end AM4 and entry level AM5 builds and it offers unrivalled performance for its price, all while being easy to install, and keeping the 9600x in my personal rig at 50-60 degrees in modern AAA games on cranked settings. Will be featured in many future builds.

awesome cooler for the price
overkill is the name of the game with this one. i bought it for looks as it does look awesome in my PC but my temps dont move. i dont overclock and dont game but i have no doubt my CPU will never overheat with this mounted on it. runs totally silent with good air movement
