Undervolting GPU on Dell Studio 1155 laptop

Hello there,
I have an old laptop running Arch Linux. And I encountered issue with GPU (ATI Mobility Radeon HD 4570 (RV710)) temperature, is too high: about 50°C-60°C in idle or browsing and about 70-90°C in basic games like OpenMW. I cleared vents and changed thermal paste on cooling system, CPU temperatures is good, but GPU is too hot. I want to find a way to undervolt GPU to reduce heat.

I tried to some software for AMD GPU's like corectrl or radeon-profile, but it does not provide a way to undervolt so old GPU's

Re: Undervolting GPU on Dell Studio 1155 laptop

I tried to switch power managments dpm/dynpm/profile, but voltage control also did not appear.
I tried to flash vbios on Windows, but ATIWinflash when I try to dump vbios always prints

error reading from rom

message.
