Review: Quiet, Cool, and Looks Great - Installed this cooler in my PC, and it’s honestly one of the best air coolers I’ve used. Temps dropped significantly compared to my old one, and it’s super quiet even under load. Installation was straightforward, and the ARGB lighting looks clean inside the case. Build quality feels premium, and the fans are smooth and silent. For its price, it’s an amazing value for keeping your CPU cool. It works perfectly as it is compatible with my R9 5900 XT. It has lasted around 2 years since I bought it and looks nice!
Review: Excellent Performance and Value - Couldn't be happier so far with the Thermalright Peerless Assassin 120 SE. I replaced a low-profile Noctua cooler with this, and it was a huge upgrade for my mid-tower case. To be fair, the low-profile design of my old cooler wasn't a good match for my setup, but the difference is still night and day. The Thermalright was simple to install, super affordable, and even came with a decent tube of thermal paste. On my Ryzen 7 5700X3D and MSI B550M motherboard, my temps are great: Idle: ~40°C Under Load: ~71°C This is with two case fans in an 18°C room. Using the default fan profile, it's virtually silent at idle and hits a very reasonable noise level under load. Great job with this one Thermalright .

### ⭐⭐⭐⭐⭐ Unbeatable value: performance air cooling at a budget price
*by P***N on October 20, 2025*

I recently installed the Peerless Assassin 120 SE ARGB in my build and I’m extremely pleased with the results. A few highlight points: With 6 heat-pipes and a dual-tower heatsink, this cooler handles high thermal loads surprisingly well for the price. It supports both Intel (LGA 115x/1200/1700) and AMD (AM4/AM5) sockets out of the box — easy to integrate into different systems. It is impressively quiet. According to the official spec the noise level tops out at ~25.6 dBA, which means minimal fan noise in daily use. The ARGB lighting is a nice bonus for anyone who cares about aesthetics, and it does not seem to compromise performance. My experience in use: Installation was straightforward (with the back-plate and mounting brackets included). After setup I noticed lower idle and load temperatures vs the stock cooler, and the system remained quiet even under sustained load. It also had good clearance around my RAM slots and GPU (always good to check fit in your case). In terms of value vs performance, this cooler really stands out. Minor note: You’ll want to check your case’s CPU cooler clearance, the heatsink is ~155mm tall. Also, if you’re doing extreme overclocking or very high-end CPUs at 300 W+ loads, this may not quite match the very top-tier 280/360mm liquid-coolers, but for most builds it gives excellent bang for the buck. Bottom line: If you’re looking for a high-performance air cooler that doesn’t break the bank, the Peerless Assassin 120 SE ARGB is hard to beat. Highly recommended.
