i remove all the fancy tube inside the Res bcoz i'using D5 dual top. There is no typhoon at all. It' doesnt matter top or bottom up in fact they are o-ring, the problem is the typhoon inside. The tube is helpful to diminish it.

However i notice the EK reservoir is full of hairline at inlet and outlet if i compare to bitspower. Externally, EK look nice with multi in/out, but if u lick the internal part, u might cut yourself.

i wonder do u really 90d or T-block ??
