My idle temperature on my R9 380 is 76C at 0% load, why is it so high?

Solution
Make sure there is a way for air to get in your computer and also get out. If the air is just blowing around inside it will get hotter and hotter. Also make sure the hot air can't just go right back in. Sometimes where you've placed your computer can be blocking a needed vent. Or sitting papers on top of a desktop model.
