Then where is the water getting hot? Does the water temp not change when run through the block, say if water was 21c coming out of the rad into the first block it would be how hot going into the second? only 22c? I really don't know the answer to above questions. I just read that people see a delta of about 8-10c load and idle in water temp. So if that is true where is the water getting hot?
Did you read my post? You're looking at tiny fractions of a degree. Water is getting hotter, just immeasurably so.

Off the top of my head:

2GPM = 125ml/s
100w CPU adds 100J to the coolant per second
SH of water = 4.2 J/ml

Therefore assumeing that it takes a molecule of H20 1 second to pass through your block,

100/4.2 = 24 / 125ml = .2C

So with 120GPH of flow a hundred watt CPU adds .2C to the water. Again you can't even measure a change that small, so its basically nothing.
