anyway you got the point.
btw, bill just stated in another thread that the brass gives you messed up temps because it IS cooler... he just encountered the problem.. the brass feels cooler because it is...
"Metals are the best conductors. That is why we use them
for making such things as saucepans and radiators. It also explains why
metals usually feel cool to the touch. If a metal object is at a lower
temperature than your body, it will quickly carry heat away from your skin
when you touch it. The opposite is true if the metal is warmer then you
are. Then the metal will quickly give up its heat to your skin so that it
feels hot to the touch."
I grabbed that from a lab procedure off of google.. Anyway.. We can adapt that example to the barb situation.. imagine the warmer metal beign the barb and your finger being the water going through the barb... the barb is warmer than the barb, so the barb dumps its heat into the water, thus making it cool.. water doesnt have good heat conductivity (compared to metal), so it will take in the warmth from the barb.. Thus the barb is cooled (just like your copper waterblock on your cpu) and it IS cool to the touch...
And some more food for though.. the barb on the exit side of the rad should be slightly cooler than the one brining water into the rad.... try it.. i dont think it will be noticeable without a calibrated temp measruing device (oh pH where are you), but the difference will be there...

lol, your quote from the lab procedure supports my argument, not yours.
If the temperature is off, it is because of air flow past the probe, not because the outside of the barb is 3-7 (LOL, this makes the barb multiple meters thick) degrees cooler than the water. Oh and for your edification - 1 degree change kelvin is the same as one degree change C.
