Hello,
I am looking to add a couple more case fans to the stock fans that came with my Corsair Carbide 300r case and I have a few questions.
1) Am I able to connect a 3 pin power connector to a 4 pin connector on the motherboard?
2) Will a standard size case fan fit the front section of my case (behind the grill)?
3) will the cable that comes with the fan reach my motherboard (Asrock Extreme4 z77)?
4) Is the difference between a 120mm fan and a 140mm fan that big in terms of noise and airflow?
5) what fans would you reccommend?

I am looking for a fan which has very good airflow and preferably is also quiet. I am more concerned about the airflow but the quieter the better. My budget is £8-£12 per fan and I would prefer a 140mm fan as my case can accomodate both 120mm and 140mm fans. I have been looking at the Corsair SP120 quiet edition but if there are any better options in my price range it would be great if you could enlighten me.
Thanks very much!

1) Yes, but the MB may not be able to control the RPM if a 3 wire fan is connected to a PWM header. It will probably run at full RPM all the time.

2) It depends on what you call a 'standard size case fan'. The front has 2 x 120mm or 2 x 140mm mountings.

3) That depends on the fan you get. And your cable management technique. And which headers are still free.

4) All else being equal, a larger diameter fan will move more air with the same amount of noise (RPM) as a smaller fan. Or the same amount of air with less noise.

5) No preference here.

Thanks very much, I was hoping to use a computer programme to control the speed of the fans, is this possible if they are only plugged into the 3 pin connector?

Thanks again

Speed Fan is the usual go-to pgm for that sort of thing. I never had much use for it myself. If I want to control fan speed and the MB BIOS is no help, I would look into a fan controller that mounts in one of the front drive bays.
