Voltage regulators can run especially hot on late model VGA cards (ATI 4870 & 4890), upwards of 100-120 degrees C. Thus, Thermalright created a cooling solution to help stabilize VGA overclocking. Both of the VRM heatsinks share the same compatibility information (ATI 4870 & 4890). Although VRM-1 is designed to take advantage of a side panel case fan, while the VRM-2 is positioned utilize the airflow of a tower style CPU cooler (as demonstrated in the photo).

Compatible Cooler : HR-03 Rev.A / HR-03 GT / V2 / T-Rad2 / T-Rad2 GTX
Compatible VGA CARD : ATI HD 4890/4870 VGA Card
