EVGA has announced the launch of a new cooling system for its graphics cards, dubbed iCX, which offers multiple sensors linked to independent microcontrollers for what the company claims is far greater control and monitoring capabilities than the competition.

Appearing first on the company's upper-end Nvidia GeForce GTX 10-series graphics cards, EVGA's iCX is claimed to feature a total of 11 patented technologies - including both pending patents and granted patents. At its heart is a network of nine sensors spread throughout the graphics card and linked to multiple independent microcontrollers - though EVGA hasn't detailed exactly why that's better than linking them all to a single microcontroller - which then talk back to the company's EVGA Precision XOC software for live monitoring.

The data isn't just for looking pretty, either: EVGA's iCX includes asynchronous fan control, using data from the GPU temperature sensor to adjust the speed of the left-hand-fan while monitors checking the temperature of the voltage regulator modules (VRMs) and memory chips are used to control the speed of the right-hand fan. The sensor data also controls what the company describes as a 'thermal LED display system,' changing colour depending on temperature and offering a visual alarm if the temperature exceeds a defined maximum.

The iCX sensor system is combined, EVGA claims, with a freshly-designed cooling system. A die-cast 'form-fitted' baseplate and backplate make direct contact with components for improved heat transfer, heat dissipation is improved by increasing the surface area of the backplate, and the heatsink itself includes an 'optimised airflow fin design' which includes L-shaped fins for increased surface area and half-open fins with milled holes through the surface for improved airflow. The company also claims to have added an 'EVGA exclusive fuse' to protect the card while overclocking.

Full details on the EVGA iCX system are available on the official website, while the company has confirmed that it is rolling the system out to a total of ten cards including the flagship EVGA GeForce GTX 1080 FTW2.
