I've ordered a new thermostat and I definitely didn't hear anything fan-sounding but it might have been hidden by motor sound. The motor sounds as fine as it ever has, although I understand idling at 2000rpm isn't ideal/normal? That's how it's been since I've gotten it, at wide open throttle it's not uncommon for it to flirt with redlining, I don't know if that's normal either. According to various sources, one can just adjust the idle screw on the engine and reduce the RPMs when resting but there's no conclusive diagram I can find pointing out the screw in question.

 

There is something besides the fuse called "EMI filter" in the fan circuit that can puke rendering the fan inop. That is, this filter is present on all EFI bikes with liquid cooling. Not sure on yours because I don't have the wiring diagram.
Fuse, fan, wiring, thermo switch for fan. Thermo switch usually in the radiator. Once you find it, bypass it to see if fan turns on and runs.
Do you have a multimeter?

Sorry for the delay. I haven't been able to find a diagram showing me where the radiator is and it's not immediately apparent to my untrained eye. Also, I checked the fuses, all are fine. I do have a multimeter in fact.

It hasn't been ridden for two or three weeks and was definitely not having this issue before.

An update: Last night driving home the temperature reading actually swung all the way down to C while I was in Seattle's downtown tunnel, then once I got out it went back to normal. Much weird.
