Fractal R3 case airflow suggestions?

[sean]

Hey everyone, I recently bought a couple of corsair coolers so have my Fractal R3 provisionally set up as above:
- Corsair H100 acting as a front intake, cooling a 1.15 GHz 7970
- Corsair H100i acting as a roof vent, cooling a 4.5 GHz 2500k
- Some generic PWM fan cooling the radeon's VRMs

The Radeon hits 73 C under load and the i5 hits 53. Acceptable temps but I'm placing a component order soon so my question to you fine folks is what would you do in this instance? I plan to add a quiet 120mm exhaust fan in the rear but should I balance that by adding another in the bottom as an intake? The bottom vent is filtered so maintaining a positive pressure should help minimise dust as far as I'm aware

Yes, add a bottom intake to supply cool air to GPU components not under H2O. That said, your temps are not bad as they are. Push / pull would probably help the H100 on front too. The combined restriction of side vent intake, grill in front of filters, filters, etc. add up.

Good shout mate, thanks. I've added a pair of noctuas to the front rad and have an AP121 on order for the bottom intake
