ThermalrightPeerless Assassin 120 Mini White CPU Cooler, 6 Heat Pipes AGHP Technology, with 120mm PWM Fan, 1500RPM Speed, for AMD:AM4 AM5/Intel LGA 1851/1700/1150/1151/1200/2011,PC Cooler

Great for budget, cheap, and value for money builds. Noise may vary.I've become a fan of this cooler despite owning two of the Peerless Assassins and other variations. 1st off is the compact nature, and have shoved this into a Zalman Cubix case, literally have 2mm of clearance but allowing the system to run on a Ryzen 5600, some people have run it on higher end hardware like Rzyen 9800s and even the x3d processors. I'm replacing my trusty DeepCool AK400 for a 5800x I'm putting on my primary Bazzite gaming pc. The key of this cooler is the recessed nature of the fan, allowing it snugly fit into places others can't and it offers good cooling. It is best paired up with 1-2 intake fans at the front and an exhaust fan from the rear, ensuring a good flow of air and keeps the CPU happy. For most standard CPUs, I usually see it going from 45-60 C and will go to 80s and even 90s depending how the user pushes the system. I wish Noctua would release a fan specifically for this cooler, the best combo is now noctua fans + thermalright coolers for a superior air cooler. Sure the Noctua fans are more expensive, but combined with the thermalrights sturdy and robust features, it can cool the most aggressive CPUs.

If you're rackmounting your PC and need something that performs well and fits in a 4U chassis, get this.This cooler is quiet, keeps CPU temps reasonable, costs way less than the competition, is decently easy to install (the documentation is decent), and it fits my specific use cases perfectly. I recommended the black version of this cooler to some Australian friends who were building a similar type of PC and also highly recommend it. It's not *quite* as good as the standard Peerless Assassin, I suppose, but it's 85% of the experience at a smaller size.

Quiet, powerful, compact and beautiful! Well done

I purchased this cooler to replace Thermalright's fantastic SI-100 low profile cooler due to a CPU upgrade (going from a 5700G to a 5700X3D) and I elected to upgrade my cooling as a result.Cooler was easy to install, since the installation method is practically identical to the Peerless Assassin 120 and the mentioned SI-100 I've used before for my own builds and a few friends.Although cooling was fantastic for a 135mm cooler, VRM temps improved thanks to the low position of the fan, and overall clean aesthetic, the one annoying issue I've noticed is how I received the cooler.The extremely tight packaging resulted in several fins bent when I removed the cooler from it's foam protection. Although fixable with a taped-off flathead screwdriver (to avoid ruining the white finish), I believe a better packing method could be used.

It is smaller than my SE that cools i7 12700 that has more than 180W TDP but is good enough for 9800x3d that is less than 130W TDP. The installation is al.ost the same and easy. The built quality looks good to me. If you need a short cooler（13.5cm) for 9800x3d, it will be a good candidate for the price.

This is another winner from Thermalright, especially if you need a slightly smaller overall height. It installs very similar to the regular Peerless Assassin, but it is just shorter and only comes with a single fan. The look, performance, and build quality match their other heatsinks.

best performance to price ratio

I'm using this temporarily until all my parts come in for NY sff build. I've been pleasantly surprised in this lil guy's performance (no pun intended lol)!At minimal tasks my PC runs at a pretty steady 52c. Gaming, hasn't gone above 72c.I think I'll be keeping this as a worry backup cooler or pass it along to someone in need.I totally recommend this cooler
