Customer reviews
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
Learn more how customers reviews work on AmazonCustomers say
Customers like the performance of the electronic component fan. They say it's effective and worth the additional investment. However, some customers have reported issues with the quality, saying the backplate was bending visibly and the contact plate was slightly bent. Customers also disagree on cooling, and noise.
AI-generated from the text of customer reviews
Customers are satisfied with the performance of the fan. They mention it's effective, excellent, and pretty looking. Some say that the performance gained is worth the additional investment. Overall, most are happy with their purchase and recommend it to others.
"...I bought this in September. It works well enough that, "I'll get around to that water block next week" has turned into, "I'll get around to that..." Read more
"...Excellent performance. Very pretty looking as well. Should probably note that I kept the fan since it looked so nice...." Read more
"...To me, the performance gained is worth the additional investment and I am very satisfied with my purchase. YMMV depending on your budget...." Read more
"...dropped the temps under synthetic loads by nearly 20 deg C. Works for light overclocks but more limited by the air flow in the small case at this..." Read more
Customers have mixed opinions about the cooling of the electronic component fan. Some mention that it cools great, has an excellent heatsink, and is a workhorse low profile air cooler, while others say that it still runs hot and the temperature just continued to increase. Some customers also mention that the thermals are disappointing and the manual is incomplete.
"Cools great. One problem I've noticed is the fan ramps up and down. Due to the fact that copper conducts the heat much quicker than aluminum...." Read more

"This is a good cooler. I paired it with a Noctua fan and used in a Sentry 2.0 case. It does not fit an Asus X570 ROG STRIX mini ITX tho...." Read more
"...The temps were still high after that, so I ended up disabling hyperthreading and undervolting the CPU to get the temps down...." Read more
Customers are mixed about the noise of the electronic component fan. Some mention that it has a decent noise level for an air cooler, while others say that it is annoyingly loud. The fan with 3D printed clips barely helps with noise issues, even when installed in a case.
"...Its noise level is decent for an air cooler. That's not the same thing as quiet, though. It's an air cooler. Moving air is how it works...." Read more
"...It is slightly louder than the Noctua l9a fan, but only by a very small amount (~5db)." Read more
"IGN confirmed. This thing is loud." Read more

Customers are dissatisfied with the quality of the electronic component fan. They mention that the backplate was bending visibly after screwing the cooler down, the motherboard warps and bends around the socket, and the contact plate was slightly bent and warped.
"...With the washer solution the motherboard warps and bends around the socket in a very unhealthy looking way...." Read more
"...and totally copper sound like a win-win, however the contact plate on mine was slightly bent and warped meaning I did not get proper contact with my..." Read more

Its noise level is decent for an air cooler. That's not the same thing as quiet, though. It's an air cooler. Moving air is how it works. Moving air is also how noise works.
It's pure copper, so it's *very* heavy compared to aluminum coolers. But that's a feature, not a bug, because copper moves heat much more efficiently than aluminum.
I bought this in September. It works well enough that, "I'll get around to that water block next week" has turned into, "I'll get around to that water block over the Christmas holidays."
Even though I don't plan to use this long term, it will be a handy thing to have around for future projects after I replace it.
The major downside is the price. This cooler should be around $50. But it is in short supply and, like so many other things, is currently being scalped for double or more.
There are two issues with this cooler though. First is the fan. This cooler uses the same fan, but in a different aesthetic, as the aluminum c7. It is known for being annoyingly loud and that does not change here. The fan is also custom mounted onto the heatsink, so if you want to replace it you'll need to buy an adapter or fabricate yourself some other solution. Second is the backplate. The backplate is an all in one solution, which means it's huge. It will interfere with rear mounted m.2 drives on mini itx motherboards and may interfere with other components on the rear of the motherboard PCB. They include an alternative solution involving washers instead of a backplate for this. It technically works, but it doesn't look healthy one bit. The pressure that a cpu cooler puts on a socket is extreme. This is why backplates exist, to spread that extra force across it. With the washer solution the motherboard warps and bends around the socket in a very unhealthy looking way. I ended up taking my dremel to it and grinding off some of the excess of the backplate that I won't ever use. There is no reason for this to be a problem if they just included multiple designed backplates per socket configuration. At this premium price point, this should be included, not some weird washer solution.
There are places online you can find a 3d printed fan adapter for purchase to mount a standard 92mm fan. I bought one ($10) and replaced the fan with Noctua's 92mm slim fan. The height is the same and the noise is substantially lower. An expensive solution, but it does get you the best under 48mm air cpu cooler currently.
This is no longer available it seems. Rumors are that they're working on a graphite coated version to replace this, which allegedly is even better. Unfortunately the fan and backplate seem unchanged.
Have it cooling a 1700x in a Node 202. Max temps full load at 68c. Max TDP for Chip is 95c so well within thermal limits.
Material Thermal conductivity (W/m K)*
Copper 385.0
Aluminum 205.0
At first I thought it was an issue with the thermal paste so I reapplied and try it again and got the same results. I used an entire tube of thermal grizzly kryonaut (tiny tube) before I realized it was a defect with the cooler itself. Fortunately my ryzen 2700 X came with a pretty nice stock cooler to fall back on.
If you're purchasing one of these be sure to take a razor blade to the contact plate to make sure it's completely flat before wasting an entire tube of thermal paste.
