I needed to get a new cooler for my PC as my H80i V2 was getting a bit old and inefficient and I really wanted to get back to air cooling. After checking a ton of different reviews, and cooler options, I decided this was the best bang for the buck, plus it looks super nice. Pros: - The mounting was VERY easy and intuitive, not once did I feel like any of the parts were going to bend or snap, or jeopardize my PC in any way. It feels very high quality especially at this price point. - Does a great job of cooling, I've never had to worry about thermal throttling, stays under 80c at high load while gaming. - Easily clears taller ram sticks, no concerns there, I have almost an inch of room over my old Corsair vengeance RGB DDR4 - RGB looks great should sync up with most controllers out there just fine. - The style in general is just nice, very clean white, no exposed heat pipes on the top, good looking fans. Cons: - I only really have one con here, and that is the noise. The fans are unfortunately kind of loud at load. Idle is just fine, but they have a very noticeable woosh and hum to them when at load. I'm not going to fault anything here because they do push air very well, but if you're looking for quiet you may want to change out the fans. Overall I'd definitely recommend this cooler!

Thermalright works great, it's the best for air cooling without breaking the bank. I have it installed with a Ryzen 9 5900X and under load it sometimes hits 85/90C, but at idle it usually stays around 50/60C, in a Mini Tower setup with 6 additional case fans.

The Thermalright Peerless Assassin 120 fans were installed easily. They work well with RGB fusion and do all the things you expect from an ARGB lighting system. They are quiet at normal processing actions but do become a little noisy when the processor hits 60 degrees C or more. 72-74 db. Normal db determined by my internal microphone is 62db. I do have an issue with one of the six fans I purchased. As you can see in the photo one set of the LEDs has stopped working. I will give it more time to see how the rest of them do. I can change all the colors, pulse them, match them with music, etc. Also the processor system fans, the GSKILL ram, my recent TForce SSD sync together with the Thermalright fans. I am pleased with them save the one little caveat of the one with some failed LEDs on it.

One thing to know about this is it is a thick boy. You should check that the size of the cooler will fit in your PC case. I installed it myself so it isn't too difficult to install. The processor is at 43o C. right now. It looks real nice with the RGB fans. It performs real well. I have a 4070 Super graphic card and PC games look great now.

I screwed up and mounted them incorrectly which resulted in a lot of fan noise. Once I put them on correctly, they didn't make any annoying noise, just a typical whoosh sound that wasn't unpleasant. I have the fans set to performance in the BIOS and I'll occasionally hear them ramp but it's not bad at all. I have tested them at full on speed and it's very reasonable. I normally use only Noctua fans + the NH-D15, so that's what I'm comparing them to. I'm really happy with the purchase. I made this decision after a few reviews, but primarily Gamers Nexus. (NOTE: I know the airflow for that case in my pic isn't perfect. The wife focused on having it purdy so not exactly optimal, but at least the CPU cooler fans are blowing to the left with the leftmost case fan also blowing out in the same direction.)

This is probably one of the top air coolers available especially in this price range. I purchased the white RGB model with thr front plates (non SE). NOTE: If you're using this in a ITX form factor then its important to know that the nickel contact plate is slightly off center so if you dont have enough clearance try rotating 180 degrees. I'm using it with AMD 7800X3D in a Fractal Torrent Nano with idle temp in low 30s and mid 60s under heavy load. I rearranged the fan in the back of the case, so my RGB RAM still shows. The fan noise is hardly noticeable even under heavy load, in ambient noise. Update: Taking 2 stars off.. 2 months later, one of the fans have started going bad. May be bad bearing but has a loud whine everytime it speeds up. I'm thinking to take it out completely and have a single fan cool the CPU..

So I'm into cpu overclocking and I needed a much better cpu heatsink enter Thermalright Peerless Assassin first things first the the product was packaged very well opon opening the box your met with your fans heat sink and mounting hardware along with the manual Installation was a breeze for am4 but you do need a slimmer screw driver when your going to mount the heatsink everything you need was included including the splitters to connect both fans to one header.Opon powering on your met with nice RGB lighting that can be changed to several other lighting modes and colors. Finally performance this cooler is quite good although it's quite overkill for my Ryzen 1600 in my test bench I set the cpu to 4ghz 1.42 volts and ran stress testing for about 3 hours max temps were 71C at 100% load and a tdp of 130 watts overall great cooler for the price

Very good CPU cooler. For anyone having an issue screwing it down, you’ve most likely screwed one side down too far before starting to thread the other side. Only spin the screw maybe 1 rotation before starting on the other side. The screws are designed to have a fair amount of pressure applied to make good contact with the CPU. I tried a 240 AIO and the Peerless Assassin gives me better performance, and is much quieter. I’ll never do an AIO again. Thanks!
