Thermalright Peerless Assassin 120 SE CPU Cooler, 6 Heat Pipes AGHP Technology, Dual 120mm PWM Fans, 1550RPM Speed, for AMD:AM4 AM5/Intel LGA 1700/1150/1151/1200/1851,PC Cooler

I have purchased 2 of these so far for different builds. They work and look great. Great build quality and good thermals. Granted, I hardly ever max out one of my CPUs, but it keeps my 12900k cool without issue. My other CPU is less powerful but it gets ran at 100% regularly and also doesn't have cooling problems. As long as this fits in your case, I'd recommend it to anyone looking for a solid, but still budget friendly, air cooler.

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.

The product looks and feels high quality. Installation is slightly tricky, especially when attaching the adapter, particularly if you've never done it before, as was my case. However, it's not impossible with patience and by following the included manual, which, although brief, serves as a guide. If you still have questions, the video uploaded for the product clearly demonstrates the installation process. It completely met my need to maintain better CPU temperatures. Previously, my CPU reached temperatures of 60°C/140°F at idle and over 77°C/170.6°F while gaming with the stock AMD fan. Now, with this cooling tower, I've reduced temperatures by approximately 20°C/68°F for both processes. This is most noticeable in gaming, as the temperature never exceeded 57°C/134.6°F, even though summers in my country are hot. At the time of testing, the ambient temperature was around 40°C/104°F. As I said, I'm completely satisfied with the product because it fulfills all its promises well at a reasonable price.

I was skeptical, but this cooler is keeping my Ryzen 9 9900X cool. It is operating within normal temperature ranges. At max load it hit 170f (76c). Max temp for my processor is 203f (95c), so plenty of room. Installation was simple enough, use the included mounting hardware for your processor, apply paste, mount the heatsink, then clip the fans on the heatsink. What I really liked was not having to use screws with the fans. What isn't apparent until you look closer at the diagram is that one fan goes between the heatsinks and the other on the right side. Both fans point to the rear across the heatsinks (see the diagram as it is clear) where the hot air is pulled out by the rear case fan(s). The unit fits exactly as it should on the motherboard. The fans are quiet and do the job. The paste being used is Corsair XTM60, which I've had good results with both on other CPU and GPU (I repasted my old GTX 1070). The case I'm using is a Corsair 5000D, which I picked up as an open box at (the most popular computer retail store). I have three fans in the front pulling in air, two on the top above the motherboard pulling in air, and one exit fan in the rear. I may adjust the fan configuration later, but it is doing fine. Getting back to the cooler, I am pleasantly surprised with its performance. For the price you can't beat it, and it supports both Intel and AMD processors. It is a good product. I would definitely recommend it.

Looks good and works as intended, with ease of installation and above average build quality especially for the price. It also provides plenty of clearance for easy RAM access. My only complaint about this product is that it is pretty audible at full speed. Overall this is a great product especially for price, I couldn't recommend it more if you need a great quality air cooler!

This CPU cooler is good value for the performance. Pros: -Kept a Ryzen 7 5800x cool under long gaming loads. Kept it around 60-70c max at 100% gaming load. -Cool dual tower design with two fans included. -Noise at low temps is basically silent -Actually helped ambient temps because the two fans guided air out of the case. Cons: -Installation is a bit trickier than an AIO cooler or stock coolers because it has two mounting screws. -Tried it with an i9 14th gen but needs a good case airflow. It did not do well in a sustained workload or in benchmarks. Didn’t wait for it to stabilize before closing the programs. i7 wasn’t bad and the 9800x3d was ok too. Overall a good cpu cooler for the money. I kept it in an AM4 build because it kept the same temps as a 240mm AIO. It also helps with directing airflow in the case with the two fans.

Amazing cooler, I upgraded from just the stock AMD fan and it brought my temps down by about 20C. Also not too loud yet

One of the best simple cooling fans out there, it’s easy, works on most processors and boards, keeps things very cool. Always remember your clearance on the fans and ram, some mobos have the memory very close to the cpu, this is a very big unit and if that’s the case your fans may not fit properly or change the configuration of it. First one showed up VERY used and without hardware. Amazon did fix it but there’s a terrible streak with Amazon shipping used previously returned/false computer items lately. always check your stuff asap as I don’t think Amazon vets returned items very well so there is a good chance you might receive a junk item. It’s stupid that this happens even on $30 items. The world we live in I guess.
