#1) It should mount just fine with the included backplate
#2) it should Not interfere with any part of the motherboard unless you decide to put a RAM cooler for your memory which may get in the way (my TRUE touches my Corsair dominator memory cooler).
#3) You should aim the heatsink so all the hot air either exhausts out the rear of your case or (if you have a top exhaust fan on your case) exhaust the hot ir upwards. Upwards is always my preference.
Thank you fro your quick reply.
Am i going to be able install 2 120mm fans for 100% sure.Additionally do i have to install the fans ,take air to the heatsink(intake) ,outake or both one intake and one outake.Just letting you know ,i have purchased a new mobo called Asus P5N64 WS PRO and due to it was out of stock i was asked to replace the item with any mobo i like.What do u thing i made the right thing changing it with Rampage extreme or do i have to stay with the p5n64 ws pro or even suggest me one.I dont care about price e.t.c
Any further help will be appreciated.
Please make sure that true black 120 fits in my potential rampage extreme and give my a reply a.s.ap if you dont mind.
P.s please forgive any spelling or grammar mistakes due to i am really confused about the whole case.
you can make the True black exhaust air towards the back of the case with one fan pushing air into the heatsink and the opposite it one pulling the air out and pushing it towards your case's exhaust fan. in this way the corsair memory fan should fit okay. As for the rampage itself i cant tell for you for sure as yet since i havent seen the board in person myself and there arent many reviews of it yet. Youll have to keep asking around to be sure.
Next, the Rampage Extreme is made for extreme overclockers. If you are not someone who like to tweak the heck out of your hardware, the money you spend on a board like this will be completely pointless.
