Problem whit my XSPC Pomp 2

[WebTourist]

Hi all,
i have problem whit my pomps.
I have two exactly the same pomps XSPC Pomp 2.
http://forum.highflow.nl/f37/y-new-gaming-pc-webtourist-iii-14294/
One month ago the first one ( 1 loop ) stopped working.
I sent it to highflow and they replaced it.
It is OK but after 1 month (2 days ago) the second pomp (second loop) stopped working.
I trying to find the cause of these defects.
Is it a manufacturer error or or the problem is in my system?
I checked my loops.
I flushed the entire system and did not found a blockage or other problem.
I use only
EK-Ekoolant Blood RED premix
Tygon R3603 - HighFlow - 3/8 ID - 5/8 OD - Clear


Can anyone suggest what is the reason ?

Mayby your loop is to small to cool you system. What are your temps.

run both pumps on setting 1 with the controller, only 1 pump is already overkill(at full power/12volt) in that little space.

Try to run the pump at setting 1 or 2, or set it at a fixed 7VOLT molex mod setting

EDIT :

you can see the digits 1/5 put both on settin 1 and look how the flow is, I think you burn the pumps because there on fullpower and dont have the time to cool in this small setup.
