Thermalright VRM-R1 and VRM-R2 Cooler
 

When we reviewed Radeon HD 4870 and HD 4890, both of them run especially hot on those voltage regulators. When cooled by the stock cooler, the temperature of VRM part can achieve 110°C! Thus, a set of VRM solution is needed badly. Thermalright has seen its chance and launched the VRM-R1 and VRM-R2 to solve this problem.
