Fantastic CPU cooler for a great price.
Performance is superb. Switched out my "mushroom" style stock cooler on my 12th gen i7. Idle temps dropped from 50c to 39-40c. Under 100% load it reaches about 52c, which is fantastic compared to the stock cooler that was giving temps of over 70c under full load. Fan is whisper quiet, perfect fit for an lga 1700 CPU, installation is easy if you already have a backplate, otherwise you have to take out your whole motherboard to attach it to the rear. Looks great in the case. Took me about 15 mins to install ( had to remove a proprietary backplate to install, overall pretty easy ). For the cost, its a great buy.

A truly impressive performance for the price. Pretty quiet and keeps mid-tier CPUs cool.
Grabbed this cooler on a whim and impressed by it so far. Threw it on a 12600k in an ITX build. Very happy with the results - keeps it around 58*C under an all-core stress test for a couple of hours. Really impressively for such a budget cooler. Aside from performance, the other thing I'm impressed by is volume. The fan is one of the more quiet ones I've heard - or, not heard? Cooler looks great, too. All black is always in. Careful though: the fins are ridiculously sharp. I sliced my thumb and now I guess I can say there are literal blood, sweat and tears in this system. Good news is that you don't actually need to risk life and limb since the fan comes pre-installed (I switched orientation of mine due to the ITX case). Honestly one of the best performing budget coolers I've ever used.

So much better than a stock AMD cooler!
Ok, let's be honest...this is an absolute insane deal for a CPU cooler. Does it perform as good as something that costs 3-4 times as much? No, it doesn't but it's still so much better than a stock AMD cooler that comes with previous generation Ryzen 3 and Ryzen 5 series CPU's. I built a PC for my nephew using an AMD Ryzen 5 3600 CPU and I was forced to use the stock AMD wraith stealth cooler that came with it. Then I came across this cooler a few months ago and I was astonished at how cheap it was. I wanted to give it some time and wait for some reviews to be submitted before I ultimately decided to purchase it. After seeing some YouTubers review it, I decided to save up some money (all $17) and just buy it. Here's my thoughts so far: - Aluminum heatsink fins do seem a bit flimsy and you have to be very careful when installing to not accidentally bend one of them. - I like how it included an extra set of clips in case you wanted to get a second fan to stick on the other side of the heatsink. Making this cooler a dual fan solution might be a good experiment in the future. - The temps did change considerably after installation. Not only did the CPU temps decrease by 10-12 degrees at load but the ambient temps in the case changed as well since this cooler helps push air out of the case. - It's honestly not that loud under load. I may even under-volt the CPU a bit to make it even quieter! - I am noticing more and more cheap alternatives to this product but I went with this one because I really liked the all black design.

A Graet Air Cooler for Novice and Amature P/C Builders/Users.
I bought this Air Cooler from Watching a Jayz Two Cents Video and I was Amazed at how well it worked. Be that what it may I built a Core I-5 Build so it didn't need the biggest cooler and this thing delivered all I needed. I'm running an MSi B760 DDR4 WiFi Tomahawk Motherboard with an Intel ARC B580 with an MSI 650 Watt PSU. So I didn't need the latest and greatest just something dependable and inexpensive this cooler was just right! Great quality and function. Wishing you all the best in your Endeavors.

All That It Needs To Be
This cooler is exactly what it looks like, it's cheap, but functional. And it has a nice blackout aesthetic to it, no exposed copper and aluminum. The performance is decent, and is good for an upgrade over a stock cooler. The heatsink sits offset from the CPU cold plate, so you'll want to install it such that the fan is above your RAM. If you want to install it the other way for some reason, I foresee RAM clearance being an issue. Installation was my only pain point, the instructions seemed clear at first, but getting into it, it was harder to install than expected. Bags were mislabeled for what socket they were supposed to be for. Parts didn't fit snuggly enough which made it a bit harder to install. But once everything was in place, it works well. It's not unexpected, but I'm still happy that it included extra fan clips. I had another fan from a previous cooler that I was able to attach and improve performance. Because of the clearance I mentioned above, I needed to offset the fan off of the heatsink a little bit to not hit the RAM, no big deal though.

PC Tech of 30 years - Awesome Product, superior "Machine Finish" - but 2 negatives
I was surprised by the quality of the air fins., Unlike other brands, the fins were not sharp (as in cut your fingers sharp) It also does a good job cooling, considering you are building with CPUs that run at 65w ratings and not 125w. I decided to try this cooler because it was on sale at a crazy low price compared to the main brand that I normally buy. And I also understood that the cooler only has a regular black fan. For anyone who is considering this cooler, the black fan is an aesthetic decision. You can also replace the black fan with any fan, even aRGB, because it uses the standard springs to hold it place. Mounting the block was a bit more complex that the other brands I usually buy. I quickly learned that to get the cooler block (the tower part) to align with the 2 mount base screws (these are built onto the metal bar scaffolds) I had to leave the 4 mount post scaffold screws screwed down but untightened, so once I screwed down the two cooler block nut heads, the scaffold screws were in their proper position. The above confusion is because the holes in the scaffolds are not individually drilled, and the scaffolds can 'drift.' Note that I never had these issues with other manufacturers of similar cooling towers. Although I gave this cooler an excellent rating, I would NOT buy this model again unless it was on sale at a similar super low price.

I had a cryorig cooler before, installed this and reduced temp by 10 degrees, great cooler for a budget price

OK, for the price the quality seems good. I bought this air cooler for the AMD 5 7500F CPU. It came with a tube of thermal paste and accessories for AMD and Intel chipset. I had to change and fix mounting brackets before screwing the unit to the brackets. However, not sure if it was the motherboard but once I fixed the mounting brackets I couldn't screw the cooler over the CPU. Due to a slight tolerance and the thumb turn screws were so tight, I just couldn't get both screws to lock into place. I had to take one mounting bracket off and fix it to the cooler and then fix the mounting bracket to the motherboard which was very fiddly, hence the 4 star review. Hopefully, it doesn't come loose and fall off......fingers crossed!
