## Customer Reviews

### ⭐⭐⭐⭐⭐ Be quiet is the name
*by K***. on March 25, 2025*

Its quite and looks good and temps are good on my ryzen 7 9700x and its easy to install

### ⭐⭐⭐⭐⭐ Well made AIO CPU cooler
*by J***S on April 27, 2025*

This is a well made ALL IN ONE CPU cooler. It is one of only a few that is refillable. The refill port is located on the front of the radiator and has a plastic insert covering the port. Signal RGB can control the RGB lights that adorn it. The fans are ultra quiet so far but I haven't tested it with games yet as I am waiting for the Gigabyte Aorus Master to come tomorrow. So far I feel like this is a perfect AIO and I am glad I choose it for my first PC build. I will update if anything changes.

### ⭐⭐⭐⭐⭐ Keeps my 9800X3D cool and runs very quiet
*by D***Z on January 11, 2025*

I currently use it on my 9800X3D CPU and under ultra settings at 1080p gaming for something like marvel rivals, helldivers 2, destiny 2, it is keeping it around 60°C and it runs oh so quietly. I cannot hear it even under heavy load. The lights are beautiful and fit the aesthetic I was looking for. I was doubting on whether or not I wanted to keep the fans it comes with but I really ended up liking them and they perform beautifully with the quiet design. They helped me achieve the gloomy sky and flashes of lightning look I was going for.
