Fractal Design is exceptionally well known at this point for their Define series of cases. However, their Celsius series of all-in-one liquid coolers has also proven reliable and popular with their older designs performing exceptionally well while also having some interesting features. Based in Sweden, the company has gained quite the following over the years with their commitment to minimalist, elegant designs—it is not all that hard to see why.
In today's review, I take a look at Fractal Design's Celsius+ S28 Prisma. This standard-sized 280 mm all-in-one liquid CPU cooler delivers RGB lighting and sleek looks, but where it differs from the competition is the built-in PCB that handles RGB and fan control on the radiator. This addition helps limit cable clutter and makes for an exceptionally clean-looking cooler with everything configured. Our review sample being a 280 mm offering will also be a nice change of pace since the majority of all-in-one liquid coolers tend to utilize 240 mm or 360 mm radiators. That said, let's take a closer look at what is in the box.
