I'm going to have 4 fans in my full tower case 300w PSU with an abit kt7a mobo. Heres the setup. (1) A 80mm 3pin on the (front bottom) blowing in. (2) A 80mm 4pin blowing out from above the powersuply. (3) A 80mm 3pin mounted on the side above the HSF blowing out. (4) A 80mm 3pin right below number 3 blowing in onto the PCI cards.

How does this sound?
What brand and speed fans should I get?
How will the #2 fan do on 4pins connected directly to the PSU?

Thanx

The more air flow, the better. You should try to overpressure yer case a bit which means, have a little more air coming in than you have going out. As far as what brands and speed, some of the better brands are Panaflo, Delta, and Sunon. The speed depends on how loud you can stand it. Generally, the faster a fan spins, the more airflow it has and also, the louder it will be. It's usually better to connect larger fans to your power supply with the 4 pin connector because most Motherboards only have a limiter current rating on their connectors for fans.

FWIW, the fan headers on the KT7A will each take up to .5A of load at 12V (6W). That's a lot of fan.

Sunny Florida, you can keep the midwest!!
UnlimitedSpeed, I would put a 120mm 60-70cfm (Panaflo or Sunon) in the front, to get more air into the case. Then a 92mm (Sunon or YS) on top of the case as a blowhole pulling out the rising heat. Last of all 2 - 80mm ( Panaflo or Sunon) one blowing on CPU/MOBO and the other blowing on the video card. You might want to consider one more fan in back above the PSU pulling air out.
You don't have to get the high CFM fans, they are real noisy, just so you have decent are flow.
But all this is useless unless you have a good HSF that is lapped and can handle the CPU heat.

You might want to consider building a fanbus. This will allow you to add, subtract, and depending how you build it, control fans and fan speed. Check out http://www.fanbus.com. Also, try to go for the larger size fans. They can move more air with less noise. Also, as TT120 said, you want to try for a slight overpressure(intake). This will help prevent dust buildup. However, don't have too much in, as this creates deadspots, which trap heat in your case.

I disagree with da whip on one thing. The blow hole on the top of the case does nothing but disrupt airflow. Positioning is just as key, if not more, than how many fans you actually have. I myself like having fewer big fans as opposed to more smaller ones. This gives you just as much airflow with less noise. Just my opinion on fans. :)
