Booted into Win and my 780Ti is down ~10k and TPF is up 4 seconds. I know WU can differ and I only ran one unit in each OS, but I'd say free 5% PPD bump ain't bad.
Also, the utilization looks a lot better now with the 3770K, still not the 97-99% i wanted but 96-98% is way better than the 86-92% I was seeing with the old Athlon II.

On my post is the GPU-Z info. I never touched any settings so I guess its auto. It says 57% fan speed. I assume the titan must throttle to keep itself at that temp as that's the max temp it ever goes too. But it also says GPU load is 99%. So if that's correct, I would think turning up the fan speed won't result in anymore PPD's?
Actually, starting with Kepler (iirc) Nvidia has changed the fan/thermal/clocks settings. You have boosts clocks which depends on temperature (and power consumption), I guess to keep the cards noise as low as possible the reference are configured to run right at a limit which Nvidia decide is safe to run these chips on (around 80C).
When you hit the thermal limit it can ramp the fan up or start lowering the clocks/voltage to keep the temps in check. My 780Ti seem to adjust the clocks/volts after it has being "warmed" up, when it's running at 83C the fan seems to settle at ~70C and the boost clock is jumping up and down somewhat. Right now the nominal boost clock is 1072MHz, in FAH it will boost up to 1137MHz if the thermals are low enough, when it starts to throttle down I've seen it go as low as 1097MHz, usually it runs at 1110MHz. The voltage is 1.15V and 1.087V for those clocks.
Going 100% fan I pretty much stays at 1137MHz all the time. which is my I want a water block for this one, badly, as that will be able to keep it cool and low noise. At 70% the ref cooler is all but quite...The card is a EVGA 780Ti ref with a stock SC ACX bios, no in-OS OC.
I found out on my 660 too that I gained roughly 20MHz by bumping the fan to 100% vs letting it run on auto.TL;DR
: Turing up the fan on Kepler can actually increase your clocks, give it a try!
