Two features can consider in fan models esp for bedroom use is whether they got remote control and off timer.

Simple ones like Deka has 1,2,4,8 hr off timer. More ex models like Panasonic Nami has 7 speed and also 1,2,4,8 hour plus sleep mode and Yuragi (breeze fuzzy logic).

These are good to pair with aircon esp on hot days such that aircond is turned on (manual or timer) to cool room first. Then when sleeping, raise temp slightly and if possible silence or lowest fan mode while turning on fan at medium or low. Wasn't Panasonic the one to innovate aircon and fan pairing (Bayu?)

I heard some friends who say that on hot days, the best combo is an aircond with a Nami fan. They swear by the Nami sleep function and off timer combo. The surrounding air in wee hours of morning already cool enough so no need to turn on so long. They on fan before sleeping and time it to off 8 hours with Nami's sleep mode to bring fan speed down gradually. Air cond off by 3 or 4. They keep aircon temp at 25-27. Combined with medium fan speed windchill feels like 23-25. Naturally will wake up when get warmer around 6:30. This strategy helps jimat lektrik also.
