I ordered this cooler yesterday and it should arrive today or Monday.
I am going ot mount it exhausting with 3 fans to the rear part of the tower, do you guys think it would fit with 3 fans? I think maybe the last fan would not fit coz of the case rear fan?
However, here is a picture of the rear end of my set-up in my Lexa S:
Sorry for the terrible picture quality here, camera phone.
Anyways, I have a push/pull fan orientation set-up on my NH-D14. This picture shows the pull fan at the end of my NH-D14, as well as my rear exhaust fan. Note that there is more then enough room to mount the rear case fan even when there is a pull fan on the heatsink.
However, do note that both fans are 25mm. If you are planning to use a 38mm fan, like a San Ace, it might be a completely different issue.
One thing you can try though (initially suggested by ehume), is to cut out the rear fan grill and take off the rear case fan, and keep the push/pull orientation on the heatsink.
