    • Affordable, reliable, and worth the purchase
Style: PA120 SE ARGB
Comes with everything you need for setup, AMD, and Intel. The cooler is very straightforward to put together. It fits well in the case I purchased for it, and the RGB is really nice to look at. It's super quiet, I don't notice it at all, and the overall performance is nice for my DDR4 build. Also comes with thermal paste, so win-win. ... show more

    • Unbeatable value: performance air cooling at a budget price
Style: PA120 SE ARGB
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. ... show more

    • Great CPU Cooler

Very good gpu cooler, pretty big so make sure it’s compatible with your case, and also make sure your ram is low profile or at least not big to the point where it will have constraint issues, I paired it with the patriot venom 32 gb ddr5 6000mhz cl 30 and it just barely fit, but it was good, the argb was very good, looks great, assembly wasn’t bad but the heat sink is a bit annoying, some cpu coolers have a cover over it so that you don’t scrape your hands over the heat sink when trying to put the fans on, but for the price it’s expected, performs great, keeps my components cool on idle at about 30 Celsius, never goes above 50-60 Celsius at full utilization. ... show more

    • Keeps temps really low
Style: PA120 SE ARGB
This cooler works really well and keeps my CPU temps way down compared to stock. It’s quiet even under load and installation wasn’t too bad. Definitely a big upgrade for the price. And for it’s price and performance I’d say it’s a great deal.

    • Does a great job keeping it cool, a bit large though.
Style: PA120 SE ARGB
Keeps my i7 very cool. 25 to 27° C idling & plenty of headroom under load. Cheap but very effective cooler. Installation was tricky due to it being awkward to get paste on because of it's size & shoe. Also screws have to be turned a lot before contact so you have to screw fast to keep the paste from getting tacky. Was certainly doable though. Fans are very quiet, especially at idle. Downside is it's big, very big. You need small memory or you'd have to put a fan on the back side to use bigger memory sticks. Maybe not for a novice but worth a shot. ... show more

    • Overkill but good
Style: PA120 SE ARGB
Review Image by Mike
Bought it to make a pc for my friend I7 8700 , rtx 2070 super , 2x8 2333mhz ddr4 ram , 650w psu . Its overkill cooling tbh , with a stock cpu fan curve playing a cpu intensive game like pubg at ultra cpu was at 45°-50° . Almost no noise at all . Looks great too . But it is very HUGE . Mounting the cpu is easy but the fans were kinda confusing and I had to watch a YouTube vid , but Zach tech tips has a short installation vid . Something to note , if you have rgb ram you will need to install it like me , the proper way to install in an intake in the front (which would be above the ram , pulling air into the cpu that comes from the front ) and one in the middle as exhaust ( blowing hot air out ) but I didn’t put one above the ram because this is my friends first pc and maybe he may want to upgrade ram , so I wanted everything in the pc to be accessible. Keep that in mind if buying this . Other than that because it’s most likely an overkill cooler you won’t be missing because the cooling difference is literally less that 5°c ... show more

great cooler, keeps ryzen 7 5800xt under 80C no problem. Keep in mind that you do need to change back bracket if it is not AM4/5. Seems really quiet compared to the stock prism cooler.

    • The best option for me
Style: PA120 SE ARGB
This cooler is a beast. The only downside is that it can be tricky the installation of your have high profile memory ram, but the two cooler towers deliver. I prefer this that can last for many many years than a AIO that only last 8-10 years, the fans are easy to replace and looks very very good
