Question :I noticed that on your website there are two types of 4890/4870 VRM Heatsink. What are the differences between them and how can I make a choice?
Answer : 4890/4870 VRM heatsink comes in two types so that you can decide which one to best work with your air flow system. R1 is the preferred choice for those who have the side panel fan while R2 is ideal for those who have the CPU tower cooler. For more detail please refer to the below illustrations.

Question : Does it really take a heatsink of that magnitude to cool the VRM part on the 4890 and 4970 video cards?
Answer :Yes, indeed the card will run especially hot on those voltage regulators. While running test programs such as the favored Furmark, the VRM temperatures can reach as high as 100 – 120 °C. Thus the need for a set of VRM solution such as 4890/4780 VRM R1/R2.
