Northbridge Heat Problem

[BrianInfo]

OS: Windows 7 Build 7100 64-bit
MB: EVGA SLI LE
CPU: i7 920 D0
RAM: OCZ3x1333LV6GK
Cooler: Thermalright TRUE Black
Fan: 2x Scythe Gentle Typhoon -15
Paste: GELID GC-Extreme
Case: Silverstone RAVEN RV-02


With speedstep and turbo boost enable, I let the PC run with manual 100% fan for couple days, see if I have set everything right before overclocking.

When just idle, the reading from CPU-Z and BIOS:
Vcore: 0.93v (multiplier only x12 due to the speedstep)
NBcore: 1.14v
DRAM: 1.61v
CPU VTT: 1.40v

CPU Temp: 26
NB Temp: 67
VREG Temp: 46
System: 38

I wonder if there is any fan I can install onto the EVGA SLI LE NB heatsink (it goes vertifcal, not a traditional flat heatsink). If not, how can I improve the temperature on my NB or possible VREG before starting to overclock?

thanks~

Best option (with out modding) would be to direct an Antec Spot Cool to that NB. 67C is very hot for a NB.

Newegg dosen't seem to have it.
