I know that that works (The mount on the 200mm fans), but I want to use my own top panel fans. That's my main question. Sorry for any misunderstandment. And i'm talking about these fans to install on the top panel for pulling air into the radiator (Delta 4000RPM Fan http://www.newegg.com/Product/Product.aspx?Item=N82E16835213010)
the answer is yes,I looked it all up by using google,you just remove the 1 factory installed 200,and there are mounting holes on the top for a dual rad mounting with 120,fans,I'm pretty sure the push/pull will work just fine.depending i believe on how high the heat spreaders are on your memory.
I know you want to use your own top fans,but as far as cooling and noise,i think you may be better off leaving the 200's in,
