Great air cooler! Mounted easily on my b550 motherboard. Keeps my hot running 5800xt cpu decently cool. Instructions were simple and clear to read. The all white looks amazing. The lighting is pretty bright. The only downside is ram placement, the fan has to be put offset to the cooling tower by 1/2 an inch. But overall, works amazing and so far has lasted a good year and half with no issues. Would recommend

First off… I love this product. When it fits, It works out great! Just look at those pictures. It looks dope in there. It's so big it's dwarfing a 3 slot 30 cm long graphic card. And the cooler.. Ooh...I was so surprised at how perfectly the color from the case fans match the cooler ARGB fans. If you want to your PC look fly on Cheap and also have it perform good, It's hard to beat this CPU cooler. And the performance... that's the best part of this.. I'm getting CPU temps of 70s on my 7800x3d using this.. And I spent less the 40 bucks. Installation is simple enough. Lots of people made videos installing this CPU cooler into their machines. I happen to have done this on a AM5 motherboard with a 7800x3d chip. The problem is making the CPU cooler fit can be hard. I was sweating if I even would be able to get the glass on my computer case when I got this. This turned out to be not an issue, I ended up with a center meter to spare. The real issue is if you will to clear your ram sticks like I did. I managed to clear it with space for a ARGB header cable to slip under, but only because I had bog-standard ram sticks that did not have fancy lights. If you have fancy ram, those big fat sticks of ram that look like they got something to prove to the world, and light up like it's Christmas.... you might want to just get a water pump and 240mm radiator CPU IO instead of this. But if you want to chuck your fancy ram sticks... you can still put the fans on the back of the CPU cooler radiator instead of the fronts, or even move them up a little, so the fans stick up. Chances are the CPU will clear the ram if they are taller than stock. The other problem you will find with the fan is getting the cable for the ARGB header is hard... like this should have been a few more inches longer. I just was lucky my header was very close... but this is why you see cables leave all over the place. But hey. If you can't the ARGB header cable to stretch to reach... it's a 5 dollar problem... I have seen ARGB cable extensions on Amazon, that will help you if you have this problem.

Easy to install, Better watch your memory height. Had to offset one fan to clear my memory. I’m running crucial , non rgb memory. The temps look very good. CPU is in the mid to upper 60s while running Msfs2024 in VR, with settings on high mostly. The fans on this cooler are RGB, and they look great. I definitely recommend this one. The price is way more reasonable than I expected.

After 3 years, It was time to upgrade from my AMD stock Wraith Prism air cooler that came with my 3900x processor. I was simply sick of how loud it was. It ran at a constant 50+ decibels (I used an app to measure) and 3000+ rpm. I also looked at my CPU temps for the first time while playing hogwarts legacy and it was running at 100c while playing and at 85-90c while web browsing. At less than half the cost of a premium cooler, the peerless assassin was worth a try. When I went to take out my stock cooler, I discovered that I had never clamped the cooler down all the way and it was loose. DOH! My computer was not cooled properly for the past 3 years. After removing it, and going through some trial and error installing the peerless mounting hardware, I finally got the peerless in place (with thermal paste). Also, I didn’t know thermal paste was already included! I figured best be safe and use the more expensive $6 paste I bought separately. The Fan installation was confusing however and that took more youtube watching and trial and error. My ram was too tall so the fans don’t sit flush on the cooler, the fan had to be lifted about 3/4 inch to accommodate the ram. (middle fan was fine). Next, while looking at the included y-splitter for powering both fans, I discovered one side was 4 pin and the other was 3 pin. I assumed it may have been the wrong splitter because you would assume both sides would be 4 pin to power both fans from the same power source on the motherboard. However it turns out this is normal and only one fan uses the 4 pin while the other uses a “slave” 3 pin to match the rpm’s of the other fan. When I finally got both fans connected to power I tucked away the other cords and didn’t worry about RGB because my computer was already looking fugly as hell with the giant new air cooler. When I turned on my computer, it was still pretty loud, but I knew that I had to tune my fan curves still to make sure the fans were turning at the right rpm in relation to cpu temps. I used MSI Center software to do this. After the tuning process was complete I was blown away by how quiet my PC was. It was night and day. Also, looking at temps, the cpu was now sitting comfortable at 40-50c while browsing and 50-60c while gaming. The temps were cut in half and the noise was also cut in half, if not more!!! Should have done this from the beginning of building my PC.

This cooler is really impressive. The noise is almost nonexistent, even with my ear a foot away it's hard to hear the included fans. It keeps temperatures low ~70C max on my 7800X3D. The lights on the fans were easily configurable with OpenRGB. Only issue, which is not the fault of the cooler, is that I had to offset the outer fan to fit with my RAM sticks.

This thing is a beast and it works 10times better than your average Air Cooler for your CPU's! I put mine on my i9, and it works great! I have a cheap brand on another one of my computers, and you can hear it from 10-15 feet away easily! Cooling performance works great! It is a little on the large size, but you don't have to worry about liquid spilling all over your motherboard.

Came with all the parts, super well packaged, and works like a charm. My only real criticism is with the directions: if you've never used fan clips before the instructions are... violently unhelpful. It guides you through the brackets and stuff fine and then says 'attach heatsink' (doesn't clarify facing any specific direction which could trip up some people) and then, my least favorite part 'attach fans'... how? The diagram is so dense with details in this step the visual is unreadable. There's no description written. I had to look up tutorials online to get a proper visual, which felt silly because it was very simple. I've installed a few heatsinks and I'm by no means a pc expert but I can follow instructions and know generally how things function so I was able to navigate it, but I wish the directions were more clear for less experienced builders. Again it works beautifully though, no issues after installing it!

Exactly what I needed. One of the best quality coolers at this price point, and it made a massive difference in bringing the overall temperature of my system down - about 12 degrees cooler at max load vs the stock Wraith cooler. It also fit just perfectly in my compact ATX case, which I was worried about.
