Peerless Assassin 120 Mini Black 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

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.

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.

Was at about 85°c - 90°c while gaming on an i7-12700, after replacing the old cooler with this one I comfortably run at 70°c, I should also note my case is fairly compact and I have the bare minimum of fans in right now so all things considered it’s doing a great job

My 5 year old system with i9-9900K and RTX 3080 is still working great. Been playing Borderlands 4 with FSR enabled, this uses the CPU to generate frames and it has made the game buttery smooth at 1440P. After a few months and over 300 hours, my previous cooler started to make some weird noises and ultimately failed. I use a Silverstone Technology Grandia 11 Compact ATX Home Theater PC (HTPC) case, its very low and makes it hard to find a cooler capable of cooling this know to be hot CPU. Installation was a little challenging, the thermal paste that came with it, so thick and dry, I couldn't use it, luckily I had lots of it from all my pc building experiments. It took some effort to allign it and get it screwed down. The cooler blows to the side, one one side is my RTX 3080 which runs very hot and on the other side the power supply. I decided to blow the hot air to the power supply side, wish it could have been rotated to blow to the back. I'm back playing Borderlands 4 and the case gets very hot, but so far I don't experience thermal throttling and I am ready for the next DLC ! Was one of the very few coolers that fits inside the 146mm height limit of the case.

Perfect little cooler. I think Thermalright was brilliant for entering this weird little niche of SFF coolers. This thing punches way above its weight class. I'm using it on a standard I7-12700 and have 0 complaints. It fits well, runs quiet, and keeps my CPU cool even in the tiny little case I'm using. Great little cooler.

Amazing cooler!

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.

I have an application where the case height keeps me from using the larger air coolers and no space for an AIO in that build. After a recent round of upgrades I was left with an option for a CPU that is honestly a bit too powerful for the space but it is in hand and pricing is going off the rails for everything PC right now surrounding DDR5 and more. Where I have used the Assassin cooler of the traditional height and been impressed, this "mini" one, not so much. This cooler is barely quieter and no more effective than the Wraith Spire I replaced. Giving serious consideration to just sending this one back. Would not recommend for anything powerful in the CPU dept.

Todo llego en buenas condiciones, pero al ser vendido por Amazon eua pueden existir retardos, no tan importantes, pero puede que que se retrase, bueno en mi caso fue así, jaja.

Working better than expected and fits LGA2011-3 square ilm.

The Thermalright Peerless Assassin 120 Mini Black is a solid CPU cooler that’s exceeded my expectations. It's a much more compact design, so it fits nicely in tighter cases but still manages to pack some serious cooling power. The six heat pipes and dual tower design keeps CPU temperatures very cool in sustained stress tests. Love the all-black anodized look. It’s got a clean, stealthy vibe that blends in. Installation was straightforward, look 5 minutes on an LGA 2011 build. Build quality is great as well, the fins don't feel as flimsy as the old Coolermaster kings that Thermalright has been dethroning recently. Performance was wild. 1 hour stress test on a 130W TDP CPU peaked at 63 deg C. That's beating many entry level liquid coolers, without the maintenance. Overall, the Peerless Assassin 120 Mini is a fantastic choice if you’re looking for an efficient cooler. I'll probably get the larger version for my next build.

I needed a cooler because the stock cooler that came with my CPU just didn't cut it. Without really stressing the system much (no overclocking), the temps were approaching 90C. Installing this cooler, the temps dropped significantly by like 20C. Idle temps are now in the 50s or less, and I think it was in the 60s when playing a fairly demanding game. I specifically got the Mini because my case wouldn't have had the clearance for the normal Peerless Assassin. Install was a bit tricky as the fan clips were hard to clip in and screwing the cooler down to the motherboard was a bit challenging while inside the case. It came with a tube of thermal paste.
