Style: PA120 SE WHITE ARGB
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!

I picked up the Peerless Assassin 120 SE, and it has been fantastic. What I Love Simple 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 Quirk Manual 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 Tip Attach 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.

This air cooler was surprisingly good for the price. First of all, it was packaged very neatly and protected very well. It has a really nice, big heatsink and good fans with it. It's quiet, and comes with a lot of mounting hardware, so no matter what motherboard you have, you can use it. Although hard to get on first, it is a relatively simple set up process. Set the backplate for you motherboard under it. Put the spacers on the holes, place the retention brackets over the spacers, and then screw it in until the backplate and retention bracket are both snug against the motherboard. Take off the plastic piece from the heatsink, and then screw is onto the retention brackets. Take the fans, and position them with on ein the middle and the other on one side of the heatsink, both facing the same way and use the clips to keep them onto the heatsink. The fans also come with a splitter cable to minimize the total amount of fan headers needed. My one gripe is the fan clips. I just don't like them, they're somewhat hard to get on properly. If the fan clips were easier to get on, there would be no reason to get a different air cooler without rgb.
