This does nothing, all changes to any of these settings bear no weight. This is really fucking annoying. I don't think exit values are being applied after closing the miner out.
EDIT: If you trim down the max fan speed, it launches at max. 65-85 launches at 85
Are you sure you dont have something like AfterBurner open or another GPU utility that has the setting locked at 100%? Have you tried loading the GPU's BIOS into something like VBE7 to check its temp settings? It sounds like the smallest temp increase is shooting your fan profiles straight up to max and that is usually something in AfterBurner or the GPU BIOS itself
