Well I've installed the GPU. Everything works fine. I've two 12V power supplies, a 120W going to the picopsu and another 192W is directly wired to the PCI-E power connector and PCI-E bus extender for the gpu. I haven't done any case mods to improve airflow yet.
Giant mess of wires, Foam pads are just placeholders for now:
Custom backplate. You can see the GPU has been shifted ~5cm to the right so I don't have access to the other ports:
I've set a custom fan profile in MSI Afterburner so the the fan is off when less than 60C then ramps up to 70% at 90C (anything above is 100% fan). The fan is off during normal HTPC workloads. I played Dishonored for about an hour today and reach a max temp of 79C (fanspeed = ~50%). IMO this fan noise is fine while gaming. It managed to maintain [email protected]
with all settings high, but i guess this game is fairly cpu light (I wasn't OC-ing CPU either).
One issue with the AFOX 7850 is I can't seem to change the vcore voltage or set the core / mem clockspeeds lower than 300/150. I'm guessing this is a software issue.
