Testbed configuration

Processor and motherboard is cooled using liquid cooling system (LCS).

Voltages and temperature level

MSI Afterburner tool informed about default clocks and voltage of 0.937 V for a 3D mode:

GTX 465 voltage and clock info

Our laboratory includes EVGA GTX 470 SuperClocked video card with voltage of 1.012V in 3D mode. It would be wrong to compare voltages of different card models. Each card based on GPU GF100 has an individual voltage value. Voltage value is set by GPU microchip itself and BIOS shows value change range for possible voltages.

Let take a look at the voltage table using NiBiTor:

GTX 465 BIOS voltage table

Voltage value range for performance mode is set from 0.925V to 1.075V. We conclude, that according to particular card sample voltage value in 3D mode can reach 0.92V or even 1.075V. What voltage will you card have no one knows for sure. BIOS indicates voltage values for Desktop and Blu-Ray Playback modes to be 0.875V. and 0.8875V, respectively.

Lets check PoV GTX 465 temperatures in reference to operation modes (for 3D mode, a 30 minute run of Metro 2033 game was used) and make control measurements with multimeter:

3D Load607 MHz800 MHz0.9370.944 V89°С61% (2540RPM)

I have been examining Fermi cards for quite a long time now and for me personally the critical noise threshold is determined by 3200-3500  RPM of fan speed. AS we see, the maximum fan speed during gaming was 2540RPM — the noise level is comfortable.
