A lot of posts criticize the coolant temp of the test, I don't quite see why though. Higher coolant temp might not represent typical conditions for our application but how does it change the validity of the results? Afaik it only accentuates the differences thereby minimizing measuring tolerance which appears to be a good thing to me. Maybe someone can enlighten me to the error in my thinking.

Don't have much else to say about the test, if ThermoChill and HWlabs both state the pressure drop figures are completely wrong I have to question the accuracy of the results (not that results are universally valid for pc appliaction in the first place).
