Hello everyone,
I've been having this problem for a couple of months now. First, my CPU fan started randomly going faster or slower (with the matching increases and decreases in noise), even though I have the frontal fan controller that came with it installed, and operative for years now. Installing Speedfan seemed to fix this - for a while. But now, as the thread title states, the cooler runs at full speed (and noise) all the time. I hadn't changed any BIOS settings, voltages or anything before the problem started, so I have no idea of what the trigger was.
Here's what I've tried.
- Setting the speed manually using the knob in the controller does nothing - it's the same at the minimum and maximum.
- Running Speedfan to control the fan speed does nothing.
- Enabling Q-Fan Technology in the BIOS for automatic speed does nothing, regardless of whether the fan controller is plugged or not.
Cooler is a Thermaltake Volcano 12, on an Asus A7N8X-X Deluxe motherboard.
Thanks in advance!
