Thermalright is said to be working on a bolt-through kit (BTK), the GF 100 VGA BTK, that lets popular existing VGA heatsinks by the company to support the NVIDIA GF100 GPU, on GeForce GTX 480 and GeForce GTX 470 graphics cards. The Thermalright Spitfire, HR-03 GT and HR-03 GTX heatsinks will be able to make use of the new BTK. The company is also said to be working on two new VRM heatsinks that are tailor-made for the reference PCBs of the two cards, the VRM GTX 480, and VRM GTX 470. These allow existing users of the above three heatsinks, and people looking to buy them some future-proofing. The GF 100 VGA BTK, VRM GTX 480 and VRM GTX 470 will be released in the weeks to come.
