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 picked up the Peerless Assassin 120 SE, and it has been fantastic.What I LoveSimple To Install: Different mounting hardware for Intel and AMD came in the box: standoffs, a backplate, screws, and even thermal paste. Just screw the backplate on to your motherboard, put the cooler base on, and then clip the fans on.Rock-Solid Performance: It kept the temperatures noticeably in check under load- awesome for an air cooler and new contenders that are quite expensive.Included Thermal Paste: Not sure how it actually compares to any premium pastes out there, but it worked straight out of the box.One Minor QuirkManual Language: The instruction sheet is only in Mandarin, so I had to resort to online instructions. An English insert would make things all the easier.Pro TipAttach the fan cables to the header of your motherboard before clipping them onto the heatsink. When the PC is built, the cpu connecter pins might get tucked under the heatsink, so have it pre-connected will spare you plenty of grief.If you want top‑tier air cooling without spending on liquid, this cooler is hard to beat at around $35. Highly recommend.

I recently installed three of these Thermalright fans in my new NZXT H6 Flow build, and they've been outstanding. Installation was incredibly simple thanks to the daisy-chain feature, meaning all three only took up one fan port on my ASRock B650 Steel Legend motherboard - a huge plus for cable management.Performance-wise, these fans are surprisingly quiet, even when my AMD Ryzen 7 7800X3D (cooled by a Thermalright Peerless Assassin 120 SE ARGB) is under significant load. Most importantly, they deliver excellent temperature control, keeping my entire system consistently cool without any noticeable temperature spikes. In fact, the thermal performance is even better than some hybrid coolers I've used in previous builds.For anyone seeking effective and quiet cooling without a hefty price tag, these Thermalright fans are a fantastic choice. They have proven to be a critical component in keeping my new, fairly powerful setup (which also includes a SAMSUNG 990 EVO Plus SSD and TEAMGROUP T-Create DDR5 RAM) running optimally. The combination of easy installation, whisper-quiet operation, and superb thermal performance makes them an unbeatable value. I highly recommend them!

I'm pretty sure it's one of the internet's worst kept secrets: This fan is incredible. Absolutely no need for any fancy cooling when this baby is keeping my cpu running at a cool 43 degrees (celsius) despite being on 24-7. Under heavy gaming load (e.g., Witcher 3 at Ultra+ settings with raytracing on), I'm getting around 95 FPS and not a twitch from this fan. It's nice and quiet, almost soundless, pushes air beautifully, and given the ~35 dollar price tag, blows any competition out of the water. I'm sure a custom-cooling solution would do better, but given this performance at this price point, I'd never bother going back!

Everything you've read about it is true. Quiet, cools well, cheap, easy to install, and the fans have a really low minimum fan speed.

Outstanding Cooling PerformanceThe Peerless Assassin 120 SE ARGB delivers top-tier thermal performance that rivals high-end coolers.In real-world testing, an Intel 14th-gen 40°C, with whisper-quiet operation.Incredible Value for the MoneyDespite its budget-friendly price, the Peerless Assassin 120 SE performs on par with premium coolers like the Noctua NH-D15 or AIO liquid coolers, at a fraction of the cost.Easy Installation & Wide CompatibilityBeautiful ARGB Design. Syncs with most RGB control systems for full customization.Balanced Noise Levels (With Adjustments)“Works perfectly, better than expected. Highly recommended.”

I have purchased ~4-5 Thermalright air coolers over the past couple of years. They consistently perform and hold up well.I'm not sure how well the included fans work, as I've always replaced them with Arctic fans. The same goes for the thermal paste, but I'm sure the included thermal paste works fine for 90% of use cases.Mounting hardware is included for AM4, AM5, and LGA1700 sockets. Installation can be a little frustrating at first, even with Thermalright's instruction videos. If you're having trouble, be patient and make sure your brackets aren't upside-down or facing the wrong way.Something to check before purchase (of any cooler) is that it will fit in your computer case. I haven't had any issues in any of the mATX cases I've built in so far, but it's always worth checking.Overall, a very efficient air cooler with amazing bang for your buck.

Work well. Needs a LARGE case. No interference with memory. I put the fans on backwards the first time. Youtube videos help installation. First one was for i9-12900K a year ago. This most recent purchase was for an i7-14700K. Very happy with this cooler, both CPUs stay well less than 70C when stressed.

This thing keeps my 9800x3d cool, and does it quietly. Install was quick and painless as well. You don't need something more than this if you're not planning to OC a 9800x3d, I imagine.
