I own GIGABYTE GV-R775OC-2GI Radeon HD 7750 2GB 128-bit DDR3 , it's silent and low consumption vga.
But i can't change voltage or fan rpm with oc guru II utility.

Does anyone know if Sapphire 7750 1GB ddr5 with trixx can do this? ( change voltage down and up and change rpm fan speed?)

Can you change fan speed within Catalyst Control Center?

Yes, fan speed with CCC works fine. Only thing missing, gpu voltage ':-)

My system :
2500k-3,4Ghz-1.215v, Gigabyte Z68XP-UD4, 2x4GB DDR1600, 1TB Samsung F3, FSP Aurum 400w GOLD, HD 7750 Gigabyte OC-880/800- 2GB DDR3.
Power consumption without lcd screen. Idle- 48w, load Lynx -4xcpu -128w, 3dmark Vantage 90w.
I have DDR3 version, DDR5 version is 30% faster. Gpu idle ~5-8w, load 30-50w.
