Simple answer is yes.

It matters because the blocks are designed so that the water goes in the inlet and spreads out over the entire base of the block. If you were to reverse the flow the water will not cool the block and therefore cpu as efficiently as it would in the correct direction.

The in port is situated to dump high flow water directly in the center of the block
and then spread to a collection trough that normally surrounds the cooling fins and leads to the out flow port.

My Ek Supreme HF not only requires the correct ports to be used in their intended flow but also that the ports be mounted horizontally

Oh, could you elaborate? I'm a few days from buying an EK HF block.

I dont think ek supreme hf blocksneed to be horizontal? Mine ports are vertical and my temps are amazing. You do need to make sure the top of the block and the bottom half of the block are facing the right way compared to each other tho.

Sorry for double post. I just checked the installation instructions for the supreme HF blocks and there is nothing stated about mounting them horizontally or vertically. However like I said in my previous post you do need to have the bottom half of the block and top half of the block oriented to each other correctly.

General rule of thumb ... inlet at the center, outlet at the outside. thumb.gif

If they took the effort to put inlet ON the block, you should do it lol
