Case cooling question

[Uroboros]

I have an Antec SX1030 case not made my Antec.

Since this case supports 2 front intake fans and 2 rear exhaust fans, I was wondering what the best fan setup would be to get the most cooling.

If I choose to use all 4 fan slots; should the rear and front fans be the same rating? Or should one set be stronger then the other. If I use 2 rear and only 1 front (like I am now); what is the situation then

I'm run a dual Athlon Tyan Tiger setup with 2 AthlonMP 1800+. With my Dominator 2 HSF, but temp has been lingering around 43c for the last 2 hours of surfing the web.

Anyhow..thanx in advance

I think your best bet would be to just try out the different combinations and see what works best with your particular setup.
