The PSU fan on my computer is not spinning at all. I've now run a high def video for 20 mins and it's still not spinning at all. I read there's power saving features that will power down the fan, but I'm really suspicious. (Read details below.)
Question:
Is this normal behavior?
If the fan may be optimizing for power usage, how I can test the fan? Ideally, without pulling it out of the case.
Details:
- PSU Model: LSP Ultra 550W ATX Power Supply
- All temperatures are normal or low according to SpeedFan. (CPU, HD0, Core, and other temperature monitors.) But I wonder if this detects the heat of the PSU itself.
- I'm having trouble with a video card. The card might be busted. When removed (and using built-in video) the computer works fine. But sometimes that's a sign of a power issue. When the card is in, it won't display video but Windows seems to load. Video card worked fine 1 week ago, but then I physically moved the system. Could have been damaged in transport.
