I'm in the middle of a rebuild and have added an Aquaero 6, Aqualis reservoir and flow sensor. I cannot start anything up yet as my water loop is still not complete - waiting for yet more parts

- so I'm trying to connect and tidy the electrics until the parts arrive. Some of the things I want to monitor the temperature of are right next to the reservoir and flow sensor. Can I plug the temperature sensors into the temp header on one of these instead of running the cable all the way round to the Aquaero?
Will it act like just another temperature sensor or will it be tied to the reservoir? ie Will it monitor the South Bridge temperature or will it be called "Reservoir Temperature" because it is plugged into the reservoir?
I've read that if I shorten the wires on the temperature sensor - to make them tidier - they will no longer be accurate. Is this true?
Some of the temperature sensors I have are from a Scythe fan controller. Is there any way of knowing whether these will work? Is it safe to just try them? They are similar in style to the supplied sensors but the wires are different colours.
Many thanks,
Gareth
