I immediately ruled out the SAI, as I can't imagine that would be running with the car at full operating temperature. Turned the car off, the whine immediately stopped. I didn't have a chance to revisit the issue until this morning. I started the car, and the whine was gone. Turned on the A/C, and confirmed both front fans are operating as normal.
It's really hard to tell where noises come from at times, but it seemed to be in the front half of the car, so an engine related cause is not on the suspect list at this time.
Should my next step be to check the high-speed fan operation? I can do that with a jumper wire at the relay, correct? Can that be done with the ignition off? Which relays specifically control the high-speed fan setting?
If I'm off track, suggestions would be most appreciated!
Thanks!

First... you should identify from where the whine is coming. Run the car and, with two people, listen for the whine fron the front, middle, and rear of the car.
Yes. The fans can be jumped from the relays. I replaced both fans (one? I forget.) and don't recall if I had the ignition in the off or accessory position. Do a search upon this forum... I believe I covered my challenge and certain of the details may be covered therein.
Find the source, first.
If it is a fan... easily you can access it (either one) with wheel removed then peeling back the fender well liner. If you need a fan let me know. I saved the one that wasn't "bad". I replaced both from a wreck with 60K miles on it. My car at the time had ~128K.
Best wishes.
