Fractal Design continues their tradition of expandable all-in-one liquid coolers with the Celsius S24. Bucking the RGB trend, they have instead gone for a more professional and sleek design that offers usable features instead of flashy LEDs. With good performance and noise levels, it manages to stands out in a crowded market.

Great review, as always! Thank you :)

Sorry to point out - small edit: Page 4 - "Installing the Celsius S36 is very simple. "

Just a couple of minor picayune comments on the review itself:

1. The introduction's 1st few paragraphs are clearly quoted from a press release / advertisement ... and while the article starts with "From the Fractal Design website:", it's hard to tell where the promotional parts end and the review starts.

2. I didn't quite understand what is so unique about the fractal unit "integrated fan hub that uses concealed wiring to connect to the pump" tho not common among cheaper CLC units, Swiftech and EK accomplish this as well ... of course it's less of a big deal when ya have have the pump on the rad.

3. For those with some knowledge / concern with regard to the useful life of corrosion inhibitors in PC water cooling loops, (18 - 24 months) some info on how easy it as to augment adding such inhibitors or even changing coolant would be a welcome "wish list" part of these reviews.

OTOH, speaking to the product itself, I still have the basic issue that it doesn't cool as well as $37 - $45 Scythe Air coolers which are also quieter. The low flow pump and mixed metals are another reason I just would never "go there". The mixed metals things highlights the ish list item mentioned under Item 3 . If anyone has ever wondered what happens when corrosion inhibitors are not used or just reach end of useful life with aluminum rads / copper blocks, it's not perty (https://martinsliquidlab.wordpress.com/2012/01/24/corrosion-explored/). Have to wonder, especially with the LED Fad, why vendors haven't all gone w/ clear acrylic blocks and colored coolants on CLC type coolers. Looking at the pics in that link, gives on possible answer.

I've had mine for a while and couldnt get clear answers from support - does the pump in yours make an irregular rattling noise?

Its proved hard to record, but in a system with silent low speed fans its the loudest part, on auto and PWM settings
