I have two CompuNurse digital temp sensors. One sensor is hanging out the front of my case (measuring the air temp) and the other sensor is taped to the side of the copper pipe piece which splits the 1" flow from the pump. You can see the sensors in the pics if you look hard enough (my cheap camera does not take really sharp pictures unfortunately).

When I turn up the three 120mm fans to max (again each pushes 90 CFM @ 12v) the second temp sensor reports a coolant temp a little below the other sensor measuring the air temp.

I know the two sensors are identical to each other because they both report the same air temp if I have them both measuring the air temp. Plus as an accuracy test I got a glass of cold water with some ice cubes in it and dipped the sensors into the water. They both reported the same temp (about 2'C).

I am pretty sure my temp readings are accurate.

EDIT:

Could the air temp at the floor (where my intake hole into the box is) be 3-5'C cooler than the air 3 feet above it (where my air temp sensor is hanging out of the case) ?
