So you're interested in liquid cooling, but maybe closed-loop units are too limiting for you. You want to jump straight into a custom-loop liquid cooler. That's a big jump, though—there's a huge number of parts to peruse, and picking the right stuff for your rig is a daunting task. If this is the situation you're in, EKWB has the solution: water-cooling kits with preselected parts. The new EK-Kit S140 and S280 Slim Series kits are identical save for the larger radiator and extra fan on the S280.
EK-KIT S280. Picture this with one fan and you've got the S140.
Just a week after releasing the Coolstream Slim radiators, EK has assembled them into complete water-cooling kits including a reservoir-and-pump unit, a radiator, a waterblock, and all the necessary tubing and accessories. The kits are intended for first-time builders, so they come with step-by-step instructions for installation. The waterblock in the kits is an EK-Supremacy MX model that will fit nearly every desktop CPU released in the last 10 years, except for a Ryzen Threadripper. You also get one or two of EK's Vardar Evo 140-mm fans, depending on the kit model.
The reservoir-and-pump combo is an EK-Xres 100 SPC MX PWM unit. The last bit of that alphabet soup means that the pump can take a PWM speed control signal from a motherboard fan or pump header. The fittings and PVC tubing are EK's own, as is the coolant concentrate, ensuring all the bits are guaranteed to fit and work together.
