CPU: AMD FX-8350 Eight-Core Processor
GPU: AMD Radeon R9 270x
Motherboard: MSI 990FXA-GD65
I thought it was just my room, but yeah no heat in the winter, room temp will go from 76 degrees F to 83-86 degrees if I don't throttle the CPU.
Which is how I found this issue is drastically affected by CPU throttling. You can change "Maximum processor state" in power options, and 70-80% usually doesn't slow anything down too noticeably but stops the fans from roaring and literally shaking my desk as the thing heats the room.
More details on that setting in my bug report:

(Also, no Asus or Nvidia, and still having the issue.)
