Thermalright VRM-R4 VGA Voltage Regulator Cooler The Thermalright VRM-R4 VGA Voltage Regulator Cooler is designed for use with the Thermalrights VGA Coolers (see below) for the ultimate VGA cooling performance. Voltage regulators can run especially hot on late model VGA cards such as the ATI 5870 & 5850 to upwards of 100-120 degrees C. The VRM-R4 is positioned utilize the airflow of a tower style CPU cooler (as demonstrated in the photo). Add an 80x15mm or 80x25mm to the Thermalright VRM-R4 to enhance VRM cooling even further! Features 80mm of fin area, specially designed for the VRM of 5870/5850 VGA cardsProvides greater range of over-clocking performancePatented High-riser punched fins, give better airflow between the fin areaSuperb cooling performance for both active (with fan) and passive cooling (without fan)Double 6mm heatpipes, soldered tightly with fin, to ensure fastest Thermal conductivityEasy 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 (purchased separately) Compatibility: HR-03 Rev.A / HR-03 GT / V2 / T-Rad2 / T-Rad2 GTX Compatible VGA CARD: ATI HD 5870/5850 VGA Card (only compatible with Stock PCB design / Reference design)
