Radiator placement

Im finally getting a better radiator (THANK GOD) although I do have a small problem. Im using an acrylic case which is rather small as most of you prolly know and plan to get a black ice micro dual 80mm which I plan to mount on the top inside of the case with alittle modding. My question is....Could this be a bad thing being that hot air rises and so on because im not really looking foward to blowing hot air across the radiator although I do have other fans being used as an exhaust.

couple degrees worse at most

As long as you have good airflow into the case, you will be fine. Trash the micro, and get a bix or TH 120.1. It's more worth the investment.

you should simply have the core be an intake.

Although it goes against some principles, th ecool air flowing throug hthe rad ,,,,being exhausted at teh back or bottom, may be good

I say try both and tell us whats better

Ive decided to go with the simple black ice II dual 120mm. 837 w/hr will be plenty for me and $ is a bit of a problem right now.

get a heater core cut out the bottum of your case for it and mount 2 120MM fans on it
It will save money and look cool too
