What were you expecting? That is completely normal. Sensors sometimes need to be balanced with + or - offsets so they all read the same temp when sitting next to each other but the differences are normally very small.

Water temps will always be relatively uniform through the length of a loop as long as flow rate is sufficient. When the system is working hard the Whole volume of water increases in temperature. It doesn't start out hot from the blocks and come back cold from the rads.

the in out Rad is a measure of how much work the radiator is doing. (They can also be used as an approximate power consumption if you have a flow meter.)
i use the difference between rad in/out as the control for pump speed and fan speeds, as in my case surfing the web etc, my in/out is 0.3C and rises rapidly to >1.0C when gaming.


not sure of the use of an in/out for cpu? CPU blocks have known characteristics; for a given water flow the CPU will rise XX degrees C.



Better to use openhardware monitor to grab cpu values as you can use them directly with Aquasuite 2013 as alarm triggers.

I've done a couple of bits & pieces for basic setting up e.t.c HERE Take your time & don't try & take it all in, in one go.. Hopefully you'll be able to find something there that will help you along the way ..... I still have more to add & do so as and when I can...
