I can either use a 120mm Scythe Slipstream 1200RPM. It's a 70CFM fan with nice static pressure. Or should I buy 2 92mm fans with around 35CFM each?
I have a Sapphire card so VRM heatsink is bigger, so no worries there. However, I think I have to remove the entire HS to get the shroud off...
Weird the gpu should be mounted with 4 screws... I just thought about it, do you use a custom fan profile? The stock fan profile will probably not work since the larger fan will spin up slower.
That 70cfm fan should handle temps at stock clocks... Also make sure you're blowing air down onto the card not pulling air through it.. Pulling air though the heat sink would cool the gpu, but the VRM's would have gotten too hot (due to lack of airflow) and caused the black screen.
So run a custom profile where the fan either runs full speed or tops out at around 70c and also make sure the fan is blowing down through the heat sink and onto the pcb.
Since you're using that custom 4pin connecter you could always run higher speed fans for the mod, since you could always turn them down with Afterburner. My fan might be more than 120cfm but I wouldn't think much more since it's way quieter than my Deltas.

He can't run the Extreme HD preset since he has a 1600x900 monitor, he can set it up but it will drop the resolution and call it a "custom" setup.. I have mine running on a 1600x900 monitor right now, I'll post the results I get from it stock and overclocked when I get off work today.

I swear the blue PCB is ugly. Plus i like the idea of a little extra cooling on the backside.
Probably have to go with Dwood/TripT for a custom back plate which I think he charges a bit for.Edited by MikeMike86 - 5/25/13 at 2:49am
