|0002184: Oscillating fan speed at idle
|I just downloaded Speedfan 4.49 for the first time in years, hoping to be able to control 3 new GentleTyphoon AP14 radiator fans based on BOTH my cpu and gpu temp - entirely possible using the latest version of Speedfan.
At the moment my loop is in pieces on the floor here so as a test I tried controlling my standard Intel CPU heatsink fan using a Speedfan 'Advanced Fan Control':
I thought this was working as intended because any increase in the load on CPU or GPU results in the fan speed increasing as I wanted, however there is a problem...
Over the course of around half an hour, at idle, I produced this fan speed chart:
These are the associated temps for the same period:
As you can see, there is a badly oscillating fan speed being produced by Speedfan at idle. I don't get this with the Gigabyte Smart Fan application that came with my motherboard, but then I don't get the ability to control fan speed based on two temps with it either
Is this a known issue?
