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,PC Cooler

The Thermalright Peerless Assassin 120 SE CPU Cooler is hands down the greatest cooler I’ve ever owned, and honestly, the best one that exists right now. Here’s why I’m so impressed:Unbeatable Performance:This cooler is an absolute beast. The performance-to-price ratio is out of this world, and I don’t think there’s another cooler on the market that can match it in this aspect. It cools even the most demanding CPUs with ease, and it’s up there competing with some of the liquid coolers, which is just incredible for an air cooler at this price point.Design and Aesthetics:Not only does it perform well, but it also looks great. The design is sleek and it fits perfectly into my build. Add in some RGB lighting, and it really stands out. It’s clear that Thermalright put a lot of thought into both the function and the form of this cooler.Long-Term Value:If this cooler continues to perform at this level, I honestly don’t see myself ever needing another air cooler again. It does everything I need it to and more, and at a price that’s hard to believe. It’s rare to find something that excels so much in both performance and value, but this cooler does exactly that.Environmental Concerns:My only gripe is with the packaging. There’s a bit too much plastic, and I’d love to see Thermalright move towards more environmentally friendly, recyclable materials. This is something that’s really important to me, and I hope both other customers and the folks at Thermalright take note. Good companies should lead the way in sustainability.Final Thoughts:The Thermalright Peerless Assassin 120 SE is a game-changer. It’s a powerhouse of a cooler that doesn’t break the bank, looks amazing, and competes with even the high-end liquid coolers. If you’re in the market for a CPU cooler, this one should be at the top of your list. Just a small note to Thermalright—let’s work on that packaging. Otherwise, I couldn’t be happier with this purchase!

Have had water coolers on my main PC for the past three years, My second water system just stopped working so I decided to try air only. Install was much easier than another water unit and all parts were present. After 48 hours I've repeatedly run Cinebench for 10 minutes at a time with 100% CPU utilization on all cores, and played Dying Light 2 for two hours straight on three occasions. At this point I think it has been stress tested pretty well. Resting CPU temp with <1% load on the CPU is about 40 to 45 Deg. C. Temp with Cinebench running all cores at 100% load x 10 minutes showed 65 to 70 Deg C. Dying Light for 2 hours with a hot 3080 GPU peaked at 90 Deg C. These temps came back to the 50 Deg C range within a minute of closing the either game or Cinebench each time. All in all this seems to be an easy to install Air Cooler that is also whisper quiet and cools my Intel 11700KF CPU well. At $35 for this cooler versus $150 for another water unit, I am more than satisfied that this was the best option. Came with all I needed in the box, including thermal paste and instructions.

I was going to get a Noctua NH-D15 Chromax but there was a long shipping delay on Amazon so I cancelled it and took a chance on this instead and I am so glad I did as the performance is very similar and it was literally less than 1/3 of the price.This thing is well made, heavy, and is so much higher quality than other coolers I've purchased previously at this price point. I was amazed how expensive it feels in the hand. Heavy duty. Assembly was very easy on an AM4 using the included bracket.I'm running a 5900x on a B550 and at stock settings it never passes 60c after 3 hours of prime95 smallFFTs. This is fantastic cooling performance. I decided to cut it back to 65w eco mode and disable PBO/CPB/global c-states because I don't need the extra boost and then it tops out at 57c. Very nice, very pleased.

This cooler is part of a new build using an AMD Ryzen 7 7800X3D/ASRock X670E Steel Legend motherboard. After using AIO liquid cooling on all my computer builds for years, I thought about making a switch to air cooling based on many recent articles the two cooling types. Thought I'd give this a try and compare for myself, considering the price difference. Install was pretty simple and the included fans seem to perform well enough to get the most out of what this air cooler can provide. After bootup and running the system through its paces, thermals are comparable to my AIO (3 fan). Very quiet during gameplay.My dislikes:Included instruction sheet was pretty minimal and the illustrations really didn't help explain how the clips attached the fans to the cooler. A few minutes on YT videos cured all issues with install.The other downside to this cooler (for me) is that the heat-pipes rise is just short enough when installed on my motherboard that the one fan is sitting on top of my G.Skill RAM (Trident RGB area) after installing according to the instructions and viewing some videos. For me, this happened when installing the fans in the "push" configuration from the videos. If the heat pipes were 1/8th of an inch taller, it wouldn't have been an issue. I may look into changing the fans to a "pull" config (where they are pulling air through) and changing their location on the cooler. However, I'm in no hurry right now as there's no functional problems, just my OCD kicking in a little. Was there any thought given about taller RAM sticks of performance RAM during design? No idea and nothing noted online. Just my experience with this item.Works great and the cost is reasonable, considering how expensive it is right now to tackle a new computer build.Would recommend.
