Aspire A515-54G - FAN almost constant on. (No heat issues). Override it somehow?

Hi,
I have a Aspire A515-54G ( NXHN0ED0019370A85E7600 ) and I'm in general satisfied with the product. However, I do have one issue. The FAN - irrespective of load and temperature - goes on and off constantly. It's like on the clock.
As I had no luck on this issue re-installing the OS, I figure it's a deeper issue. Can I, with this model, raise the threshold before it decides to raise the fan speed? I can't find it in BIOS as I can with my desktop PC, so we need a more creative solution here.
Ideas?

Thanks!
