I have ordered the alphacool one finally, but wanna know if water resistence of this block is high cos I found the crack inside is so narrow and the space inside seems not a lot for high water flow.

Another option is to order a MIPS cooler specifically made for this board or to use an Alphacool 4-eyelet block like I'm using. However these options all require ordering from Europe whereas the DD block is readily available in the US.
