I think it’s getting near impossible to gauge waterblock performance nowadays. You’ve got the Apogee GTX giving 4 C variances based on what O-ring is installed, dependency on the type of processor...there are just a lot of variables now and flow is just one of them. I don’t know if you can really draw anything from having better performance with less flow. I don’t think anyone can say with certainty that what worked for you will work for others.

And you know what that means...more testing!
