I also built up a system around the Q11 yesterday. But not with the A8-3850 (but nearly) - finances looked better so I took an i7-2600K+Asrwock Z68. Nice little setup! With a Corsair H60 (Mounted on a 140mm Alpenföhn EKL Wing Boost as front Fan), CPU temps never go above 50°C in Turbo! The biggest problem were the stiff water tubes from the H60, but with some light pushing all fit perfecty. I did not take photos. If you are interested, I would go and open the case (8 tiny screws - YEAH!).
The A8-3850 I would have cooled with Scythe Shuriken (not Big Shuriken, that one is too big!). You would need to turn the CPU-Fan around, so it pulls away the hot air from the MoBo/cooler, so the direction of the air flow is the same as the one from the PSU-Fan (sitting directly above the cpu-fan). With opposite directions, both fans fight for the air, which would probably lead to heat problems.
ATM installing Gentoo. 7 minutes 48 seconds for compiling glibc - yeah! An Athlon II X3 435@2,9GHZ needs 21m 15s - impressive speed gain. The X3 with WD Caviar Black, the i7 with WD Caviar Blue.
Scythe Shuriken 100mm is the hsf I got
the psu is fanless, silences and efficiency were my main goals with this build
I'm not as concerned with high performance (I guess my tastes are changing)
I had to modify the shuriken because the asus board has the cpu socket very close to the pcie slot. I simply bent the heatpipes leading to the upper heatsink moving it up maybe 20+mm
now only if I could get the voltage to scale with powernow_k8 and the ondemand governor
voltages aren't shown in dmesg after loading powernow_k8, only the clockspeeds
the clock speeds appear to be changing, but power usage from the wall remains constant ...
