940's do run hot. I have one also. I believe it's stock Vcore is 1.35 or 1.40. I was able to drop mine down to 1.275 and still be stable, which decreased my temps to 58°c at full load. However, if your idling that high, you having a cooling issue. Are you using the stock heatpipe cooler that came with the boxed version, or is this a OEM 940 that didn't come with a cooler? Also your case should have a 120mm fan in the front and one in the rear, as the best CPU cooler won't do any good if it's not getting air. If it's a cheap case, then consider modifying it for better air flow, and for folding you may want to have a blow hole in the top with a good sized fan (heat rises) like many of the gamer cases have.
