I think I'll give it a shot, I'll get extra tubes and test with different setups. It's bout' time for me to do some real life testings, and I really hope I can find a balance point between the look and functionality. Thats why I'm ordering a 3x120mm rad

Logically guessing, since the MD20rz has a pretty high pressure rating, as long as the reduced tube connectors are not leaking, I think there should be enough flow in between them, I'm afraid it might be too fast running through the big rad.
Anyhow, extremely apprecaite for all your helping hands, I should have came to this forum earlier
two thumbs up
