The Thermalright Peerless Assassin 120 SE V3 is a no-nonsense air cooler that punches far above its price tag. After testing it on both an AMD Ryzen 7800X3D and an Intel i7-13700K, I’m convinced this is one of the best value-for-money coolers on the market.Performance:This dual-tower monster handles heat like a pro. Even under heavy gaming or rendering loads, my CPU temps stayed shockingly low—often within 5°C of premium coolers twice its price. The 6 heat pipes and dual TL-P12 PWM fans work seamlessly together, delivering silent operation at idle (sub-25dB) and only a mild hum under full load. Compared to my old 240mm AIO liquid cooler, the Peerless Assassin matches its cooling while eliminating pump noise entirely.Installation:Surprisingly painless for a dual-tower design. The mounting kit supports both AMD AM5 and Intel LGA 1700 out of the box, and the included screwdriver and thermal paste (decent quality) saved me a trip to my toolbox. The only hiccup was RAM clearance—taller RGB sticks might conflict with the front fan, but sliding it up a few millimeters solved the issue.Build Quality:Robust construction with a clean, understated look. The aluminum top cover adds rigidity and hides the heatsink fins nicely. Fans are securely mounted with anti-vibration pads, and the PWM control ensures smooth speed transitions.Value:At this price point, it’s almost unfair to competitors. It cools as well as (or better than) popular mid-tier coolers like the Noctua NH-U12S or be quiet! Dark Rock 4, but costs significantly less. The included second fan and full compatibility with modern sockets make it a steal.Verdict:If you’re building a high-performance rig without splurging on liquid cooling or overpriced air coolers, the Peerless Assassin 120 SE V3 is a no-brainer. It’s quiet, efficient, and built to last. Thermalright deserves applause for delivering flagship performance at a bargain price.

Easy installation, provides enough cooling for my Ryzen 9 9900x. Just keep in mind the ram height so you'll be able to use it without having to adjust the fans. Build quality is pretty good and the noise level was low enough to not be a bother.

This was an upgrade over a very cheap, very poorly made DeepCool cooler from 8 years ago. I used it for 6. It worked just fine, but after so long, I figured that I should upgrade.Getting this to fit was a bit of a pain, but that just comes down to my motherboard and case. Installing the cooler and the fans themselves was not the hard part, it was very easy. Just follow the instructions, make sure your parts are positioned the same way as the photos. Save yourself some pain and make sure you do some research to see if this will fit in your case. It's pretty darn big.I had to remove my top exhaust fan and replace it with an Arctic P12 Slim, which fit perfectly. The right side intake fan of the cooler sits on top of my RAM, causing it to be about 1cm higher than the heatsinks. I asked around online and everyone says this should not be an issue at all. Again, this is due to the construction of my board and my case, no fault to the cooler. The only difficulties I had were due to my case and board.I used Arctic MX-6 paste instead of the included paste. I also bought Noctua branded PWM splitters, without realizing this comes with one. So everything you need is right in the box, no need to buy paste or splitter if you don't want to.Performance wise, I have not done any real thorough testing, but just from keeping MSI Afterburner and HWInfo open, it seems to have reduced the CPU temps significantly, perhaps a good 5-15c lower on average compared to my old cheap cooler. If you are using an older cooler, this will be a good upgrade for you. Air coolers have improved so much in the past 4-5 years, so if yours is older than that, this is worth the price.Noise level, I can't really comment on it. I'm always running fans or some other background noise at my house, so I'm not really worried about how loud my PC is, as long as it doesn't sound like a fighter jet, which this does not lol. Surely it's nice and quiet, but if you really care about acoustics, do some more research.Overall, this is a great CPU air cooler for the price. The build quality is very high, the performance is great, and the price is affordable. Again just make sure this can fit in your case to avoid any issues!

This is for Peerless Assassin V3. I upgraded to the 9800x3d and while the deepcool AS500 PLUS was good for 5800x3d it just wasn't doing the cooling for my cpu. The 9800x3d was reaching 95°c on loading shaders only and in some scenes of the same games it would do the same.Now this Thermalright P.A. V3 is great and Boiii does it do a much better job. On loading shaders, same games, the highest is only 85°C Max and is only for a shorter amount of time. I only had to raise the one of the fans up about a quarter of an inch for clearance so that the first ram slot taken wasn't covered.This peerless assassin V3 is really worth it imo, especially if last 5 or 6 years. This is my 2nd air cooler and let me say, it is totally worth it. Just make sure you case has plenty of room for it, with good airflow. With a 2,000rpm it works fantastic for cooling. Mine reached 2,120 rpm at 85°C. It also has a CPU, TDP of up to 265 watts, which my previous deepcool had only 220 watts. Even though it doesn't say it on the box.I have full size case with plenty of airflow, I also didn't need rgb, as like my build just blacked out. So for this price it is also worth it. It also compares to some dual liquid cpu coolers, but at a lower cost. Thanks you Thermalright for the best dual cpu cooler I have purchased so far, and Amazon for the fast and damaged free delivery.
