I have a Radeon R9 270X (Sapphire OC Edition 4 GB to specific) and I was wondering if 70-75 degrees celsius is too hot for it while playing Rust on max settings or Battlefield 4 with max settings. Is 70-75 good? The frame rate is high and the graphics look great. Just wondering if that's too hot for it. While it's on idle (such as right now), it's 25-30 degrees. Thanks.
