Fractal Design Celsius S36-360 mm Radiator – Silent Liquid CPU Cooler – PWM – Intelligent Controls – 3X Fractal Design Dynamic X2 PWM GP-12 120 mm Silent Fans Included – 1/4 Inch Fitting – Blackout

This is installed in a Fractal Design R6 case at the top. The instructions allude to the capability of expanding this radiator system. However, I do not believe the pump has enough capacity to add any other devices. The hoses could be a bit longer.My ASUS ROG CrossHair x570 motherboard does receive the pump RPM signal but is unable to control the pump speed with the pump running ~ 2000 RPM continuously. In the end this works okay for my use. Also the motherboard is unable to get a signal from the pump concerning the coolant temperature so I have to assume these functions are not available.But for the price I paid, this is the least expensive 360mm radiator with three fans and so far it is working well for general, everyday use. I hope it continues working well when I start gaming with this AMD 3900x CPU.

Review - Fractal Design Celsius S36 AIO Cooler-The first glaring problem with this AIO CPU cooler is that the documentation is absurdly terrible. In fact nearly every product sold by Fractal Design has this same problem. Each Fractal Design products has a cutesy manual with ridiculously uninformative - one sentence - instructions with large pictures on each of its pages.-In the instance of the Fractal Design Celsius S36 AIO Cooler, the instructions for connecting the radiator fans are essentially non-existent. There is a sort of fan leader wiring hub on the radiator, but no information in the manual about how to use it. The primarily problem with this lack of documentation is that the hub has input jacks but it isn't at all apparent what one would do for OUTPUT from the hub to the CPU FAN HEADER on the computer's mainboard. Also, next to the little hub is a wire that leads to the covered cabling system toward the pump, , but it isn't clear where that fan hug wire leads. There is a wiring lead for the AIO pump, but there should be a separate wire from the fan hub for connection to the mainboard CPU FAN header/jack. There isn't any documentation to explain any of these details. In this regard the Fractal Design Celsius S36 AIO Cooler is a total failure with regard for attention to detail, and/or thoughtfulness about a new customer receiving and trying to correctly install their product.-So this problem gets a one star review because of its terrible documentation. We'll see how well the AIO cooler performs once I figure out how to correctly connect the fans so that at some point the fans get connects to the CPU FAN header on the mainboard. Maybe a forum or a youtube video will have answers. However, if a youtube video is the only source of information about how to install this AIO cooler, that is yet more evidence of this failure on the part of Fractal Design. Hey Fractal Design, learn to write better manuals, including providing more than once terse sentence on each page of your terribly bad manuals.

Pump failed after less than a year. Fractal will only warranty through the original supplier.
