I managed to get this apparently stable overclock (which survived successfully a x20 with Linx):



As for my setup: I am using a Full Tower Thermaltake Element V which sports 5 fans (2x120 on the Front Panel, 1x230 on the side panel, 1x200 on the top and 1x120 in the rear), cable clutter is to a minimum since they are tied in order to grant a decent air flux.

Other specs include:
MB: Asus Rampage Formula II
CPU: Intel i7-930@2.8 Ghz
RAM: 3x2GB Corsair Dominator DDR3 PC12800 CL7
Cooling: Cooler Master V8
Case: Thermaltake Element V
VGA: Nvidia GTX 275 (1896 MB)

Currently the BIOS settings are like that:

Ai Overclock Tuner - Manual
CPU Ratio Setting – 21
DRAM Frequency –1101
Intel Speedstep Tech - Enabled
Intel Turbo Mode Tech - Enabled
BCLK Frequency – 183
PCIE Frequency - 100
UCLK Frequency – Auto
QPI Link Data Rate - Auto
DRAM Timing Control – 8 8 8 24
CPU II Phase Control - Full Phase
CPU Voltage – 1.33125v

Anything which could improve my temperature (I idle at 41° and top 91-89-87-87° with Linx x20) without giving up further speed or stability?
