it was a Hatari 16" fan too noisy with a capacitor. I binned the Capacitor and don't use the fan night time

Oh, so not a variable voltage regulator then like the one posted earlier.

I settled on this Xiaomi one. Look like pretty good reviews re gentle speed, low noise and easy to clean. DC inverter which means you have very low and overall good speed control and torque. Basically an aircon fan but a lot easier to clean. Take off the back panel and the whole rotary turbine thing comes out to pressure wash outside. Got a pretty good deal too with Lazada coupons for 1600 baht delivered. Should be the ticket hopefully 🙂 Thanks all for the advice

I got lucky. Some years ago I had a Hatari fan that for some reason started going real slow. Was gonna ditch it but then in the winter months it's real handy as it gives a nice gentle breeze, just enough to move the air.

No good in the summer but as you know, you cant buy these.

undervolt the fan
you could do as others suggest

another option (same same but different)
use a 12vdc fan like this one
https://www.lazada.co.th/products/nnc-12-15-fan-12voltt-18w-16-bfe-40-dc-12-i4096882497

with an adjustable dc power supply, which there are many to choose from
like this one for 90 baht

i do similar on PCs with standard 120mm case fans
if no controller but i want the fans to run at low speed
i simply switch the molex connector around and force it in
so the 12v fans are powered by 5v

I have 5 speed ceiling fans in my house. The one above me now is on the lowest setting and slow enough to just keep the air circulating.  Perhaps not the price bracket you want.

Depends on ceiling height, i decided it was too big

You cant run an AC fan on DC can you? And I wouldn't use a DC rated controller to control the voltage either
