Fan placement suggestions

[HardyOne]

I just bought a Coolermaster ATCS 840 case and will start my new build soon. I think the ATCS 840 may need some additional intake fans, but I do not want excess fans to add to the noise factor. So what I thought I may try is to start with one fan on the place on the floor. The next step (if that doesn't seem to keep things cool) is to add one fan next to the lower HD cage blowing toward the MB area. Opinions?

Also, I will have an i7 920 with a Megahalem heatsink. I plan to start with one fan pushing from the rear towards the back case fan. I then may add a "pull" fan at the back of the heatsink. I plan to use a Noiseblock fan.

What fan should I use for the fan on the floor? I have heard that a fan that is horizontal takes one with good bearings. I would like to use another Noiseblocker, but maybe might need a Gentle Typhoon in this spot. Opinions?

Sorry for all the questions, but my current system has way too many fans and is quite noisy. Just didn't want to repeat this.

Gentle Typhoon fans appear to be pretty great for horizontal orientation. They have ball bearings instead of sleeve so they work better that way. I'm about to pick up a few for my new rig too.

the GT's are great.

What about the ATCS 840 case? Does anybody have any experience with making it have optimum air circulation? Will adding additional fans help? If so, which ones?

Anyone?

Still looking for help in where and how many fans to add to the ATCS 840 case to give best air circulation. If somebody has experience with this or knows of a good article that describes it, I would appreciate it.
