why did you de-ariation cycle, (pump timed to run for 30s on and 30s off for 8 hours) ?

Is this how it should be done ? Sorry for the stupid question, is my first watercooling project.

There are lots of ways to skin a fish but this is the way I chose as the pump I have has a de-ariatioon cycle built into it. Most people with PC watercooling will generally try to bleed the loop by running the pump for a period of time and then shutting it down and rocking the case. Stopping the pump causes the smaller bubbles to clump together and form a larger bubble that is easier to push through the system.

Is the problem that the heatsink cant handle 2 boards on it? If you use only 1 board on each heatsink would it make it work ?

No but that would solve the problem, the two boards that are closest to the centre of the fan gets the most airflow hence the temps are less of a problem, the outer ones don't get enough airflow to keep the temp sensor cool enough.

EDIT: Sorry I read your post again..... so the heatsink is cool.... its just the sensor that actualy reporting false temp making it to shutdown?

Thats what I think it is because I'm pretty sure there is no air left in the system but will keep an eye on things for the next couple of days, also without the fans running the temp skyrockets on both boards to 80c and then shuts down.

I will report back in a couple of days after adding the ramsinks to the temp sensors.
