Have anyone tried to replace stock radiator on GTX 970 4GD5T with a GTX 970 Gaming 4G Twin Frozr radiator? As far as i know, the boards are identical so the mounting holes should be in the same spot and all clearances should be good. The only difference is IO cover. On 4GD5T it is generally wider and has a kink in it while Gaming 4G has a smaller, straighter one. Can anyone measure their 970 Gamings`s IO shroud? How far it extends over the pcb? Is there a better way to improve 4GD5T thermals?
