Can I use a slim fan for intake, any anyone know of any good ones to use?

I have a small mini itx case ( Lian Li TU100 ) and the 120mm fan at the front is too big restricting space and airflow.

I have a mini gtx 970 from Gigabyte and a 4790k in there also

I know it's supposed to blow air into the case (intake) but I was thinking maybe I can use another fan maybe a really slim 120mm fan with good airflow but the only one I've found is the Sycthe Slip Stream 120mm fan 2,000 rpm Version which has 45.47 CFM airflow which I am told isn't very good

If you can fit a 120mm fan you should be able to get any 120mm fan. also 45 is not that bad but here are some more 120mm fans. http://www.newegg.com/Product/ProductList.aspx?Submit=Property&Subcategory=573&N=100007998%20600035590%20600035651%20600035652%20600035653%20600035654%20600035655&IsNodeId=1&IsPowerSearch=1
