lower rad temps after pump change

[mc141]

so i was using the $20 starter pump/res combo from the ek L-360 kit up until Saturday when it magically seized up overnight when the pc was off. so in an emergency went down to microcenter and bought an ek-xtop d5pwm-(incl. pump) and a new res. after putting it in, reconfigure half my loop, and rinsed out my carpet cleaner(for the red coolant that spilled allover my carpet when the plug came off the tube), i turned it on almost fd up the pump because if an air lock  (didn't notice(black tubing in basement) keeping the fluid from moving to the pump and proceeded to play dirty bomb as my bench mark for temps(only game i played enopugh to remember the rad output temp). after an hr i noticed that the radiator wasn't pumping out as much heat as before but my system temps seemed to be about same. around 60-70 with furmark and aida 64 running at same time. and about about 50 ish while playing dirty bomb.

 

 

my question is does the new pump that is way more powerful and not cheaply made have an affect of the temps and explain the lower rad temps.

 

 

my pc is a 4790k with swifttec apogee 2 block

asus 290x direct cuii with ek full cover waterblock with backplate

and for fun i have it connected to the mobo vrm cross chill thing

well if the original pump wasn't enough it may have been struggling to move enough liquid, causing the water to get hotter in places or something similar. The new pump could be more powerful is moving the liquid faster, giving it less time to absorb heat (but this is good, it means cooler water touches components quicker).
