Prime95 v25.6 Load and Post Load Idle Temps

Seems Smart Guardian app's cpu temp is under reporting cpu temps compared to RealTemp 2.90RC3 and CoreTemp 0.99.3.

System specs

Intel Core i7 920 3836A756
Thermalright Ultra 120 Extreme + LGA1366 Bolt Thru kit
DFI LP UT X58-T3EH8 R.A51
128MB Gainward FX5200 PCI
2x1GB Corsair TW3X2G2133C9DF Dominator 9-9-9-24 at 2.0v rated (Samsung ICs)
750GB Samsung HD753LJ
Pioneer DVD-RW
1KW Corsair HX1000 psu
WinXP Pro SP3 nLite fully updated

Room Temp: 29.8C

Core i7 920 @20x 133BCLK = 2660Mhz at Vcore = AUTO = 1.16 in bios
MEM Clock = 133Mhz x 8 = DDR3-1067Mhz 9-9-9-24 at 1.605v
Load CPU = 43C, SYSTEM = 53C, CHIPSET = 43C
Post Load Idle CPU = 35C, SYSTEM = 37C, CHIPSET = 41C
RealTemp 2.90RC3 CPU Load Temp = 55-57C
NB passively cooled (SYSTEM temps)

Core i7 920 @19x 201BLCK = 3816Mhz at Vcore = 1.25 = 1.26v in bios
MEM Clock = 201Mhz x 10 = DDR3-2008Mhz at 1.68v bios
Load CPU = 54C, SYSTEM = 70C, CHIPSET = 46C
Post Load Idle CPU = 42C, SYSTEM = 57C, CHIPSET = 42C
RealTemp 2.90RC3 CPU Load Temp = 70-73C
NB passively cooled (SYSTEM temps)

The higher the memory clock, the more CPU VTT voltage is needed to stabilise the system. Higher CPU VTT, also increased SYSTEM temps I think. For Prime95 @DDR3-2008Mhz, it needed CPU VTT = 1.44v, but for single threaded benchmarks like Super Pi 32M, Everest and Sandra, I could lower CPU VTT voltage from 1.44v to 1.36v in bios.

Update: Added a fan over NB heatsink and dropped SYSTEM (and PWM) temps at idle from 57C to 44C and load temps from 70C to 55C for SYSTEM and 46C to 39C for CHIPSET temps

It does seem the NB heatsink has a heatpipe that extends to the mosfet heatsink from these 2 photos of the cpu socket area - side view and top view. Hence, adding fan over NB helped reduce temps for both SYSTEM and CHIPSET temps in Smart Guardian.
