CPU Fan need quick advice

Wass up people...haha,i got the venom cpu cooler that can have 2 fans on it,i have 1 currently on it that is a "smartfan" that switches from 1200rpm to 1900rpm when needed,but i want to put another fan on the bottom,i already got the other fan,its the cooler master 2000rpm fan,which gives allot of air,so that's gonna be at the bottom,but my question is if there will be a problem when the bottom fan goes 2000rpm and the top one only 1200(when not in game use or so),like maybe a air bubble or something,so what....will it work or what?O and the top fan is the air in-taker and the bottom one is the air...out pusher(don't know the real term for it.)

Please and thanx

rule of thumb is the intake fan is less or same as air out-take to give the fan time to pull the same air out as you put in, to much in and the out-take fan will run to hard and not keep up with a smooth flow, and the temp of air will stay hotter inside the case rather than being moved out.

A good case will have extra intake vents vs exhaust vents to allow a place for air to come in when exhaust exceeds intake (ideal). One way to ensure this pattern is to get lower CFM intake fans and higher CFM exhaust fans. Or if you want you can get variable-speed fans (same brand/type, if you want good lifespan/warranties) and just keep the intake fans slightly lower. You'll also want to remember that PSU fans are exhaust fans, and if you have a dual-slot video card, that will also exhaust air from your case.

AH crap!um ok,brianzion thanx for the info,now here is my quistion for you,the intake one runs 1900rpm and gives 75% more air than a normal fan(according to them) will the out take one be able to take all the air out now?the out take is cooler master 2000rpm and give 90 cfm out

You will be fine, as it's just your CPU cooler, not your case.
