Forbidden PC Milk. Don't drink it, no, don't drink it, just gaze in wonder at EKWB's latest creation: the EK-CryoFuel Mystic Fog. This coolant is designed to diffuse light throughout the milky formula, allowing for rainbow effects with RGB blocks and reservoirs. [EK-CryoFuel Mystic Fog is available now in 250 ml concentrate ($15) and 1000 ml pre-mixed ($20). Only 1,111 pre-mixed bottles of Mystic Fog exist. Yes, the shelf life of RGB milk is limited, and EK says it has specifically fine-tuned the formula to achieve long-term stability and brilliant addressable D-RGB reactivity, making the RGB blocks shine brightest through the liquid.

"A key feature of the new coolant formulation is the perfect ratio of suspended particles to the transparent coolant base," the EK blog post states, "which gives the coolant the unique ability to disperse light. This provides the best foundation for brilliant addressable D-RGB effects in any liquid cooling system."

The coolant is packed with bio-inhibitors, corrosion inhibitors, and scale inhibitors to keep PCs running better for longer.

The coolant is also biodegradable (90% in 10 days) and will not remain in the environment or bioaccumulate, the press release states; EK suggests replacing this coolant after 6 months.

Now you can get a pre-mix of Mystic Fog along with the concentrated version at the EKWB web store for a limited time. Also, everyone who picks up a bottle will receive a flow rate indicator.
