Sorry for the title, I'm not sure how else to word it.
As said above, Warframe is causing my CPU fan on my heatsink to rev up extremely fast whenever I alt tab back into the game after it has been in the background for a period of time (I'm guessing 2 to 3 minutes), then goes back down to normal levels after about 6-8 seconds. The sound alone gives me a jumpscare in times when I forget it's doing this, and is excessively loud to boot. It has only started doing this after one of the most recent hotfixes, though I'm not sure which one caused it, and no other game seems to be giving me this issue. Anyone have any idea why this is happening and/or a fix?
