XSPC has a well known presence in the enthusiast water cooling community with a track record for high performance and affordable water cooling products. Recently, XSPC released new version of their DIY cooling kits, integrating their EX series radiators into the kit. They were kind enough to provide us with a sample of their Raystorm 750 EX240 Watercooling Kit with an included EX240 radiator. We tested this cooler in conjunction with other all-in-one and air coolers to see how well the XSPC kit stacks up. With a retail price at $149.99, this kit offers an affordable alternative to the all-in-one coolers.

XSPC incorporated many of their mid-range to high-end parts into the XSPC Raystorm 750 EX240 Watercooling Kit, making it an exceptional value for the price. XSPC includes the following parts in the kit: the Raystorm CPU Watercooler, the EX240 Dual Radiator, the X2O 750 Dual Bayres/Pump V4 reservoir, two meters of 7/16" inner diameter / 5/8" outer diameter clear tubing, 1/2" black chrome barbs, 1650 RPM 120mm fans, both Intel and AMD bracket/mounting kits, LEDs for both the reservoir and CPU block, and all the hardware necessary to put it all together. The X2O 750 Dual Bayres/Pump unit is a dual 5.25" slot reservoir with an integrated X2O 750 pump, capable of pushing 750 lph (liters per hour) or approximately 3 gpm (gallons per minute) to a height of up to 1.8 meters. Both the Raystorm CPU Waterblock and the EX240 Dual Radiator are copper-based for the best amount of heat extraction and dissipation possible.

Included with the kit are mounting kits for both AMD and Intel CPUs. Both kits share the same style screw poles, washers, and springs, with the big difference in the upper mounting plate that sits on top of the Raystorm block and the under-board hold-down plate. Both top plates are clear acrylic with an aluminum overlay and LED holes on each of the four sides of the plate.
