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
CPU PLL Voltage - 1.81592
QPI/DRAM Core Voltage - Auto
IOH Voltage - Auto
IOH PCIE Voltage - Auto
ICH Voltage - Auto
ICH PCIE Voltage - Auto
DRAM Bus Voltage - Auto
Load-Line Calibration – Enabled
CPU Differential Amplitude – Auto
CPU Clock Skew – Auto
CPU Spread Spectrum – Auto
IOH Clock Skew - Auto

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?

I managed to get this apparently stable overclock (which survived successfully a x20 with Linx) I idle at 45° and top 86-83-83-81° (Hyperthreading ON) and 80-77-76-76° (Hyperthreading OFF) with Linx x20 at Default settings:

My system specs are:

Motherboard: Asus Rampage Formula II
CPU: Intel i7-930@2.8 Ghz
RAM: 3x2GB Corsair Dominator DDR3 PC12800 CL7

Case: 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 reduced to a minimum since they are tied in order to grant a decent air flux))
VGA: Nvidia GTX 275 (1896 MB)

JUST FYI, your thermal spec for your processor is 67.9c

True, this is the Tcase temperature that you can't accurately determine, but it is widely believed that 70c-75c should be the max temperature you should ever see to be safe.

To lower your temps:
1: Lower your vcore or
2: Get a better cooler

I improved further:

I managed to get this apparently stable overclock (which survived successfully a x20 with Linx) I idle at 45° and top 80-77-76-76° (Default Settings) and 84-82-80-80° (Max Memory Settings):
