Been looking at getting some temperature sensors for my loop, to see the temperature of the water ofcourse and at some point maby setup an automated fan control instead of the 5/12v manual fan control im using right now.
i have been looking at these sensors
Though im not sure if the 2'nd one will be restictive if say i place it in the top of this rad rad, instead of the stop fittings.
and, as i am now, still use the side for fittings. it would then have the sensor down right befor the exit or entry of the radiator ?
(don't know if my explanation made sense. :-) )
Also, having a hard time figuring out how many temperature sensors is usefull, and when they become a waste.
surely 1 would surfice for controlling the fans as only 1 temperature graph is needed.
but i got the impression from reading around on some forums that its not good if there is to big of a temperature difference between two given places the loop, and the only way to know that would be to set up more sensors. (though im not sure i'd know what to do if the difference was to big anyways, as my understanding is that the water would reach an average temperature trueout the loop, only slightly varying from the exit of the radiator, to the exit of a block, given the cooling, heating properties of the two.
so how many sensors do you guys use ? if any ? and why ?
is 1 enough ? and does it matter at all where it's placed ?
