### ⭐⭐⭐⭐⭐ Keeping it Cool: Thermalright Peerless Assassin 120 SE CPU Air Cooler
*by D***H on 26 November 2023*

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 – 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 – 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 – 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.

### ⭐⭐⭐⭐⭐ Big Cooling, Small Price
*by P***A on 11 September 2025*

I installed the Thermalright Peerless Assassin 120 SE in my rig, and it’s honestly one of the best bang-for-buck coolers I’ve used. It’s got a dual-tower design with six heatpipes and two 120mm fans, and it handles heat like a champ—even with high-end CPUs. My temps dropped noticeably, and it stays whisper quiet unless I’m pushing things hard.Installation was straightforward, and it fits nicely in my mid-tower case. Just make sure your RAM isn’t too tall, since the front fan sits close. Build quality feels solid, and it doesn’t look cheap either. For the price, this cooler punches way above its weight. If you want serious air cooling without spending a fortune, this one’s a no-brainer

### ⭐⭐⭐⭐⭐ Easy to install and so much better than the AMD cooler
*by C***N on 27 April 2024*

I started with the AMD cooler to try save a little money but there was an annoying tick sound to the fan.The PA has had amazing reviews, and not wanting an AIO went for it.The mounting system is simple and easy to fit, but the instructions are a bit basic so maybe check out a video on YouTube.The supplied paste is about enough for 1.5 applications. So you can make a mistake, but not much! The tube is huge but this does make it easier to handle vs some tiny ones I've used in the past.The fans come with a Y splitter for the CPU fan header which I used. The ARGB is daisy chainable but my case has a controller with enough spare headers so I used that instead. The only real gotcha is if you have other ARB fans you might want to check where led "1" is so you can clock them the same and the patterns match. Mine are out by 90 degrees but I don't think it bothers me enough to open it all up to change it again as they are oriented for easiest cabling.The fans are nice and quiet and no annoying clicking!Temps where also a huge improvement. On the AMD cooler I was idling around 55C, I now idle at around 38C a 17C improvement! Under burst loads it peaked at around 55C so where I was idling before the upgrade.Would recommend this cooler, great value, looks great and awesome performance.
