Is there any review that is comparing older Kuhler 920 with the latest 920 v4 ? I was looking at Corsair Hydros for long time but they all have very short tubes (22cm). Antec Kuhlers on the other hand have them whole 11cm longer. SO i'll be able to stuff the cooler inside the front of my case without any problems. I'd just like to know if normal 920 and 920 v4 are that much different that are worth the wait for the shop to get the new v4... they only have older 920 in stock.
