Well as the topic says, I switched my pump to an Eheim 1250 from the 1048. The rest of my system is in my sig. So far, higher flow don't mean jack! I am actually seeing higher temps, about 3C. Of course the system is not 100% bled, probably 95% and the AS3 will need time to settle. With the 1048 temps were 41-42C load (on die reading) with a case temp of 26C. With the 1250 and the SAME case temp I load at 45-46C. The D-Tek Spir@l is a high flow block too (I think

) What do you think? Here is how my system is set up:
Here is a pic of where the pump is, this is BEFORE the rad/shroud re-do:
