fan for hs??

[Maverick986]

I picked up a Gemini II since it was cheap (free) and plan on using it on my next build.....not sure what fans to pickup for it tho....i'm not too worried about noise.....though i would like to keep noise down to standable....maybe just a slight buzz......i've seen some fans out there that are pushing something of 150+ cfm...but at around 50+dba i'm almost positive that there going to be loud...or are they? any way...would like input on what fans to use.....or should i just bite the bullet and shell out for a ultra120 hs...and then a fan for it? or would the Thermalright IFX-14 Internal Fire eXtinguisher be a better choice?
