I have a dell system which came R9 200 series, and I've updated to windows 10 when it first came out, with no issues before now. I just recently updated my driver, and installed the Crimson software, and since then, after about 3- 5 minutes of playing any game, the fan randomly goes to 100% speed for about 2 seconds, then back to normal, and it'll do it three or four times per minute. Before the update, nothing like this had ever happened. It doesn't matter what game I play, Battlefront, Fallout, World of Warcraft, etc, all the same. I even tried a less intensive graphics games, and still the same result of the fan going crazy. Just trying to find a way to fix it, or rollback to previous driver.
