Excellent for the price
Specs before cooler: CPU: 5600g GPU: EVGA 3060ti XC w/ 3080 fans Case: Be Quiet! Pure Base 500dx Intake: 2x 140mm Pure Wings 2 Exhaust: 1x 140mm Pure Wings 2 (rear exit), 1x 92mm random fan below GPU (GPU only curve) My 3060ti is my main (gaming) monitor, and I use the integrated graphics for my second monitor (browsers, file explorer, office programs, etc). I monitor temps or have a browser open while gaming on occasion. With the stock cooler my 5600G would approach semi alarming temps when playing a demanding game. High 70s maybe low 80s. Now I stay in high 60s, occasionally reaching 70. This is more than just the cooler, though. Getting this cooler I knew the fan wasn't going to be as quiet as I wanted it to be. Plus it wouldn't match. I bought a Be Quiet! Pure Wings 3 120mm to clip onto it instead. Percentage to percentage, this fan is quieter. It's also been designed for airflow and to push through radiators and coolers. I used the included Thermalright fan as a second exhaust fan (top exit). Since it's louder I gave it its own curve. At idle and doing office work the CPU temps are fine with just one exhaust. Because of this I set this fan to stay at 30% until there is some serious load being put on either the CPU or GPU. This keeps the temps right where I want them. I do believe having this fan there also helped my GPU temps a tad. In conclusion- for the price it's perfect! Very effective for a budget office setup. With my Pure Wings 3 addition, this setup isn't only cooler than the stock Wraith, it's quieter too. In the video I compare my fan of choice to the one that comes in this kit. The phone mic amplifies the volume a little bit, both are quieter in person. With that being said, the difference is still noticeable. *Thought to consider though, one is further in the case than the other. The "stock" fan I used as exhaust could potentially be muffled a small amount by the case.

Cheap and Good CPU Cooler
For the money, this is really nice cooler. It works well, but for my small kit build it's a little too big (but it fits). I ended up switching to a ASIO option which was a perfect fit. I kept the cooler as I can use it for other builds. While I did have it installed I did notice it a good job cool my CPU (intel 13th gen). If space isn't an issue for you and need a inexpensive quality cooler from a solid brand. Check it out!

Best price to performance cooler out there
I've bought so many of the single and dual fan versions of these coolers. Why? Well, they're inexpensive, easy to install, and work very well. No need to spend more money. These are the go-to coolers for me.

excellent choice in terms of price and quality ratio
Excellent choice in terms of price and quality ratio.I installed it on i5 12600kf, this cooling is enough with a reserve, so the computer runs quietly under load)

You really can't beat this for the price
This worked fantastically. Core temps stay sub 70c under OCCT stress test. Very impressive at this price point.

I was SHOCKED (not literally:))...
I was shocked at how well this fan, heat sink, and parts necessary to assemble/install it, were made. Everything fit together very precisely, instructions were rather straight forward and easy to follow, and once installed my Intel CPU is sitting under normal load, at around 81f . Initially I was going to purchase the x90 w/ the smaller fan but I'm glad I spent a few dollars more and got the 120mm fan and heat sink. ...be sure to check your case and RAM clearances. The way this is designed w/ the heat sinks elevated a bit and not close to the board as other CPU cooling 'units' are - I had plenty of room. I've also seen where people who do run into space limitations (bound by RAM or the like) and they simply install the heat sink as recommended and then attach the fan but elevated a bit from being 'square' on the heat sink - if that makes sense. Given how the clips are that hold the fan in place this would be easy to do. I guess it could effect cooling a bit if you lifted the fan too high off of 'square' but it'd be easy to do to find room if needed under those conditions. In any event, a great product and it's refreshing to know great products can be found that don't cost an arm and a leg. PS: packaging was also great and labelled really well. GL and hope this review is helpful.

Fantastic Cooler
Needed it as a emergency replacement for a budget build but honestly ended up keeping it in the build permanently because it does a fantastic job of keeping the CPU cool. Definitely would buy again.
