Thermostat for Fan

[senget]

Halo to the seniors.

Recently, my tank's temp is 29 plus degree celsius. Have been using a fan to blow on the water.

Anyone out there knows how to make a fan with thermostat? With it, then it could switch on the fan when the temp is high. Switch off when temp is low. Very poor lah, can't afford to buy chiller. Anyone could help me out?

dun think u need to do this...

swith on the fan 24/7...your temperature won't drop extremely, in fact the best a fan can do is around 26-27...that's all...

and dun forget, fan cools the tank very very slowly..

You will only need a thermostat if you DIYing your own chiller. For fans, not necessary to have thermostat.

Mine tank is also at 29 deg C. (Without lights on)

Using four 120mm, 12vdc, 0.2A fan to blow the water surface all day. Temperature doesn't seems to go down any further. Maybe have to get a better water pump and powerhead that do not give out so much heat.

No choice. Cannot afford a chiller. heheh.

Why not start saving up and invest in a chiller. It will prove to be more worth it in the longer run in this hobby. Trust me.. its better then running a fan. I can intro you cheap and good chillers..... the price is around $248. First hand chiller. I can do you this favour of directing you to the dealer but not here. Call me if you are interested. 94508599. Melvin
