Since a month my GPU (Asus EAH 4890) has been acting kind of strange. When I'm watching a video with VLC or Media Player Classic (both SD and HD), the speed of my GPU fan increases from 27% to ~40%. The temperature goes from 53 oC to +60 oC. This normally only occurs when I'm playing graphic-intense games. The problem also occurs when my PC has been idle for more than 5 minutes. When I pause the video or move the mouse, the speed and temperature drop to normal.
I've did the following:
- Updated GPU drivers
- Replaced CPU cooling fan (This seemed to be the cause at first, but alas)
- Cleaned the case and all fans of dust
- Disabled Graphics OverDrive in the AMD Engine Control Center
- Updated both VLC player and Media Player Classic
I hope I've been thorough enough in describing the problem!
