be quiet! Silent Loop 2 360mm CPU Liquid Cooler for Heavily Overclocked Systems, 2X Silent Wings 3 PWM high-Speed Fans, dampened and Adjustable Pump, 6-Pole Motor, 3-Chamber Pump, ARGB LEDs

Works Well and is refillable.

I replaced a Noctua NH-D15S with this Silent Loop 2 360mm to cool an Intel i9 13900k CPU that was being driven very hard by an RTX 4090 when rendering a movie. This cooler dropped the peak temperature of the CPU from 100C to less than 90C in initial testing. It is quite an effective device. Installation in a Be Quiet Silent Base 802 was straightforward.

Very good quality and quiet operation. SUPER! Thank you!

The radiator provides good CPU cooling once it's installed properly. The included installation guide is garbage. The 3 pin AIO (pump) header connection to the motherboard doesn't work on modern motherboards. You'll need to move the connection to the 4 pin CPU_FAN connection. Then move your CPU fans to the CPU_OPT motherboard header. If you don't, you'll melt that new very expensive CPU you just bought from Intel or AMD. When your system fails due to temperature you'll know why. The pump is over $200 and should come with an FX option for RGB lighting. I ended up purchasing Light Wing fans separately for another $80. (corporate greed at its finest) There is no reason to have such a horrible out of the box experience in today's age of computer hardware.

One of the things I see praised about this cooler is the easy mounting mechanism. However, only having two screws holding the block to the brackets can cause uneven mounting pressure, especially in smaller cases where the stiff tubes are going to exert some force on the block. On my 7900X, this was causing a 15C difference between CCD0 and CCD1 because the mounting pressure was good on one side but bad on the other, and there is absolutely no way to remedy this with the 2-screw design.It's a shame, because other than this blatant flaw, I like everything else about this cooler. It definitely lives up to the name in how quiet it is, it isn't super flashy-looking, and the nickel plating is what I was looking for since I wanted to eventually switch to liquid metal.
