How to cool the water? (Oxygen Not Included)

Perhaps one of the most important issues in the later stages of the game.
Here I have a steam geyser...
There is a hole with communications all...
If I pump water into the pit directly from the geysers, the temperature will be 50+, and the whole colony will be in after the bath is fried, and the farm where the desired subzero temperature melts.
Cool purely for the farms water through ological water (which still eats 1200 electricity), it is unrealistic. Let's say there are no problems with electricity... But should run in it 10 kg of water, it will heat up 300+ and burn. Put the valve, Lagodekhi 6 pieces in a circle, and the maximum that I reached is 700 ml. p., while ological heated to 160-170 (175 and will burn).
Put these two, except that half could provide water to one of the two farms (small).
Tried the radiator to tighten the flow of water across the room with lagodehi and 4 conder that the air is cooled. effect, from 60 to 59 cool. funny.
nachteil in the room to -200 degrees. +58 degrees on the way out.
Tried to put 10 blagoderov in a tank of water, half submerging them in water. The effect is zero.
So what to do then? How to cool the water?
