Most manufacturers of cooling solutions for graphics cards prefer not to address this matter at all releasing coolers that only cooler the GPU and send some airflow towards the PCB at best. However, this is absolutely not enough, and a great example here is the recently reviewed Arctic Cooling Accelero Xtreme GTX 280, which cools the GPU perfectly fine, but does nothing to improve the thermal mode of the PCB VRM components. But it is very pleasing to see that some manufacturers acknowledge the need for proper VRM cooling. One of these companies is Thermalright Inc. that has recently released an updated version of Thermalright T-Rad2 GTX and two heatsinks for the VRM components of ATI Radeon HD 4870/4890 graphics accelerators. Our today’s article will talk about these particular solutions.
