Windtunnels and ambient temperature

The weather is warming up here in the desert, and with it the ambient temperature in my study. Monolith, a dual-gig windtunnel, reflects the changes in room temperature through its fan noise. It’s enough to make you think that a person with a sensitive enough ear could discern the ambient temperature just by listening to the pitch of the fan noise from this machine.

Note that I’m not bitching about the fan noise. I knew how loud these things were when I bought it. It’s just funny how sensitive the cooling system is.
