    Very nice product, works perfectly

    I ordered this product to replace an old watercooler that had reached the end of its life. As usual with Asus, the packaging was impeccable. Installation was very easy as I followed the instructions step by step. I really liked the magnetic cable attachment system. At rest I have a small 33° on an I9-9900K and with a very acceptable noise level since you just hear the noise of the air. The downside is that you almost have to install armoury crate to have a management interface. (On the other hand, the AIDA64 program available for download does nothing except provide useless statistics.)

    Efficient but LCD definition is a little low

    Combined with a ryzen 9 9950X (tdp 170w), I have a very, very large cooling capacity (in a room at 20°c maximum, we'll see this summer). The noise is very contained and it's my case fans that cover up the sound of the radiator fans. The only cosmetic drawback is that the LCD screen is below my expectations in terms of graphics quality; but at the same time, it's not a 4k 100hz TV, that's for sure. It's easy to install and very modular, which isn't the case with the pachidermic 360mm.

    I love it wowwwww

    I have to admit that the temperatures are very low, so I put on the grizzly thermal paste, which has a great reputation and is the perfect combo ????????

    Impeccable wartecooling

    This watercooling is simply Wow. My processor, which is an i9 in full game mode, doesn't go above 42 degrees with a fan speed of at least 1100 rpm.
    I can only recommend it.
