#8 > I reused the ones from the original heatsinks.

When I measure the volts between the 2 waterblocks, it depends on the setting of my multimeter. If I measure with the setting at max 200V dc, the volts is 67V, when max is 20V, the volts is 6.7V.
It is very strange I think.
I think I will take it apart later and recheck all connections, but at first I will try and connect the 2 points where the original heatsink was attached.
