New video explanation.

After seeeing the new video in LTT channel about the pc with 4 rads in mini case i wondered how it is working without a pump? As Far I know you need constant running water, or I am wrong?

I haven't watched the video, but if you look at one of the radiators you'll see a big black block at the bottom, that's the pump.

In the video they fill the radiators once out of the case and disconnect it and closing the case doing loop of only radiators.

At 9:00 they show the pump attached to the radiator.

Having watched the filling part of the video, the loop doesn't have a reservoir, so they used one to assist in filling the loop and then disconnected it once the loop was full.

One day Ill follow up with taking my H100i apart and having it be the pump/block for a custom loop with no res

Its the black block in the upper left side next to the two 120mm fans at the top of the case.

Ohhh, I thought it was just a part of the Radiator.
