I don't disagree to try stock fans first. But I disagree that "Slipstream fans are terrible for rads". See
FANS 101: Going Scientific. Using a lower static pressure on a rad, such as a Slipstream 1900 rpm, can be fine if one uses 2 fans in push/pull to make up for the low static pressure.
Each fan has a P/Q curve like a pump. Similar to how a high resistance loop requires a powerful pump, a high air resistance radiator (usually high fins per inch) requires either high static pressure fans or lower static pressure fans in push/pull. This means using a lower static pressure fan, like a Slipstream, makes push/pull almost mandatory to ventilate the radiators, especially if the rad is high fpi. But it doesn't make the fan "terrible". It an be salvaged if you already have two.

With a high static pressure fan or low air resistance rads you can usually achieve your temperature goals in push only although push/pull will always ventilate rads better than push alone. Here is more on push/pull by Martinm210
