If you read the article the licensing was 14.5% now its 25.375%, these coolers can go up to around $100 retail, but AMD definitely isnt paying that. AMD already has a contract with CM, and as such they cant just go and demand more money.
AMD will pay $0 more for the furyx's contracted to CM, and when that contract ends the price for the cooler may rise a whopping $5.
Also the tweet from OC3D at the bottom and on their twitter https://twitter.com/OC3D/status/646757707345731584 is wrong. They say the cooler may cost 24% more. Which is incorrect, CM has been paying the 14.5% since before the furyx, the cost is only going to be the additional 10%.
