so i was wondering if you think a 10" fan or so should do it?
and how big should i make my intake hole?

Here are some links that give you stats on some really good CFL bulbs:

27 Watt CFL - 100 W Equal - Full Spectrum Daylight 6500K - Spring Lamp - TCP 28027-65 Light Bulb
GE Lighting Compact Fluorescent Mini Spiral Bulb, Fle45 Hlx/2/5w, 45w/150w, Model 24688 (usahardware.com)

Also, in order to find out how powerful a fan you will need you need to take your LxWxH to get your cubic feet measurement. Then you need to find yourself a fan that is powerful enough to pull your calculated cubic feet measurement once every 2 minutes to provide ample circulation. Example: if your dresser is 2ft x 3ft x 4ft = 24 Cubic Feet. Thus, in order to pull that amount of air out of that space once every 2 minutes, you'd need a fan that pulls at least 12 CFM (Cubic Feet per Minute).

Your passive intake holes should also be smaller than your exhaust in order to encourage a strong negative pressure to help with, not only with fresh air circulation, but air current circulation inside the cab.

Hope this helps, and sorry for being gone for so long,
