    Satisfied!

    Water cooling is easy to install and sober in design. Perfectly suited to my system. I'd definitely recommend it!

    Be quiet no better than MSI....

    Not even 1 year old and already overheating...air bubble...use the refill kit supplied, we'll see how long it lasts. I'm using an i7 10700k, turbo off mode, 125w max. In short, I'm very disappointed with these very mediocre quality AIOs, and I'll be switching to a ventirad the next time there's a problem.

    Very good silent cooling

    This is an excellent WAERCOOLING AIO kit.
    Set up to cool an INTEL 12400F processor, the quiescent temperature averages 35°C, with 32dB silence. For the RGB button, I replaced the two excellent BE QUIET fans supplied with the kit with a Cooler Master Mobius 120P ARGB. In fact, this one imposes a static pressure of 3.63 mm/H2O. This pressure overcomes air resistance as it passes through the fan blades. When playing games with ray tracing, the processor reaches a maximum load of 75% at a temperature not exceeding 60°C. The control is well managed and transmitted by LDLC, which is always at the top of its game.

    It does the job.

    It is housed in a thermaltake 100 with top extraction. It is an ITX case.

    It is used to cool an I5 - 13600KF non O/C

    Below the radiator is a Be quiet! Light wings 120 pwm argb and on top a be quiet! Silent Wings 3 120mm PWM supplied in the bundle. The second 120 pwm supplied in the kit is placed at the back of my tower.

    The AIO pump is totally inaudible, even in game. The PC is on my desk, 1 metre away from me.
    The fans are silent in auto mode and in full load with manual activation, they make themselves heard but it's acceptable and the noise isn't annoying.
    That said, I've left everything on auto and I never hear them.

    When surfing I don't exceed 40°, in 4K video I don't exceed 60° and when playing Cyberpunk 77 with patch 2.0, I can reach 80/83° at peak. Temperature taken with CPUID HWMonitor in a room at ~24°c.

    In my ITX case, the AIO is glued directly to the GPU and expels air from it. My only air flow in the case is the AIO and a PWM 140 placed at the bottom of the case. Because of the size of the case, it doesn't help with temperatures.

    Very good

    Very good, thank you.
    Noisier than I expected, but compact and usable with one or two fans.
