Hello I have no link because it is my information.
I bought the block because I was impatient.
But I want even better :)
And I prefer the look of the bitspower block.
I use 1 mo-ra 3420mm from Watercool with a D5 next aquacomputer pump.
On my loop I have 4 QD3 koolance or 2 pairs, 1 pair to detach the gpu on the box and 1 other pair to detach the mo-ra from the box, and the rest of a simple ek connector.
Even without the qd3, the delta was 18/20 on around 430w and with xoc bios over 500w the delta is around 22/24.
I carried out my tests with an ambient temperature of 18/20 °. And water at around 20 degrees.
I find the delta relatively large given the system I have.
Sincerely Alexandre
