be quiet! Silent Loop 2 120mm CPU liquid cooler for demanding systems, Silent Wings 3 PWM high-speed fan, dampened and adjustable pump, 6-pole motor, 3-chamber pump, ARGB LEDs, coolant bottle included

Very good and easy to install. The CPU bracket is very good and does not require the awkward hook method for AM4. Always research the CPU mounting method when buying a cooler and always avoid if it involves hooks.Once set up the benefits of this AIO were evident right away on my 5950x. Temperatures were much lower than my air cooler at idol, now around 30 degrees instead of 45. Under load temperatures haven’t exceeded 67 degrees which is again lower than my air cooler. It’s average temp under load is around 62 degrees which is very good for a 16 core cpu.RGB is easy to set up with the remote and isn’t overwhelming. You can turn the be quiet logo light off using the included pin.The be quiet fans are quiet even when they rev up and the pump hums away in the background and can’t be heard when my pc case doors are all closed (phanteks p600s).I would highly recommend this, however it would be better if the warranty was more than 3 years long.

The cooler has good performance. Using a 13990k requires a beefy cooler and a good pump and this AIO delivers good performance at an adequate noise level.There is very negligible pump whine, you can only hear it if you test the pump without plugging in any fans. Even fans that are sitting at 200-400rpm will be louder than the pump.The mounting system is one of the worst I've ever experienced. The back plate has really nice screws that fit together very well and allow for certain ease of mounting, however the stand offs are awkward to install, especially towards the motherboard IO.The mounting system barely fits on my motherboard (Aorus z790 Master) as the left bracket scratched the PD cooler and is under a snug fit with it.The pump mount cannot be easily orientated once screwed on, so this should be taken into consideration if you follow the official installation video. I personally do not care about the orientation, but it should be thought of in advance depending how you are going to mount the radiator.The tension screws are a bummer. I am not a fan of using a screw driver when it comes to mounting something on my motherboard other than m.2 drives. It is very easy to over-tension the screws and therefore it is possible to damage the motherboard. I had to adjust the tension screws for the cooler mount about 3 times, until it felt uncomfortably tight.Not using the included fans can also be tricky, I have corsair maglev fans, which come with pre-mounted (stuck on) rubber grommets which proved to be a pain while trying to mount the radiator under a pull configuration.The performance is great once mounted properly.

After 3 years, it has built up white gunk inside the radiator/pump causing high temperatures constantly. Initially I thought it was running low on coolant, when I started filling the coolant back up, I noticed the coolant bottle got white stuff from the radiator. Making the refill thing pointless.

When fitted into their own Purebase 600 case this is not ATX compliant and my new Asus motherboard would not fit as it hit the radiator fans. I contacted Bequiet about this, who just weren't interested. just blindly repeating that it was ATX compliant, even after I sent them the ATX specs and pointed out to them the exact section they failed on.

For my first time using an AIO Cooler I wanted something that's offers high performance but also very quiet.I used the Be Quiet brand before and have been impressed with all their products. Needless to say this product is no exception.My computer runs so quiet, while gaming for over 6 hours my Ryzen 7 5800x which is known for getting hot barely touches 60C. So all in all amazing cooler and would recommend.
