ThermalRight introduced the VRM-R5, a new VRM heatsink designed for ATI Radeon HD 5870 and 5850 graphics cards. The heatsink measures 1180mm x 117mm x 122mm and weighs 140g, it consists of two units that are linked with two 6mm heatpipes, and even better cooling can be achieved by attaching an optional 80mm fan.
Here's the features list:
80mm of fin area, specially designed for the VRM of 5870/5850 VGA cards,effectively lowers the high temperature and prolongs the VGA life, providesgreater range of over-clocking performance .
Patented High-riser punched fins, give better airflow between the fin area, superb cooling performance for both active (with fan) and passive cooling ( without fan).
Double 6mm heatpipes, soldered tightly with fin, to ensure fastest Thermal conductivity.
Easy Installation, “Hand Turnable” screws provided, installation can be done without any extra tools.
No extra fans needed, can use airflow from the Tower cpu cooler when needed.
One 80 x 15mm or 80 x 25mm fan can be installed ( need to be bought separately).
