I have a Sapphire HD 7850 2GB graphics card which is not over-clocked. So, I was willing to know that what are the Idle Temperature and on Full Load/Gaming Temperatures of this card specified by the Company ? 

Please, also give me a link in which the company or any well-known website is stating about its temperatures. 

Note: Please check out my country for average weather conditions.

Thanks in advance.

Just keep it under 80°C and you'll be fine, it can take over 100°C but for a midrange card 80°C on a double slot cooler should be your high point.

Umm.. can't see it.  Nevertheless there's a few programs that will automate fanspeed vs. gpu temp, MSI Afterburner being the most popular.

Thank you all for your replies, as you said Hardwood, I don't think I would require one as I've seen through a monitoring system that the GPU itself changes it's fan speed according to temperature, so is there still a need of that?

 

Secondly, Black_Zion- Thanks for the information, also what did you mean by "a double slot cooler should be your high point ?"

As, it's currently winters here in my country(India), as far as I've seen the GPU temp reaches max to 60c but for some games 65-66c also but not constant. So is thsi all good ?

Your fine, actually that's pretty good considering the ambient temp in your country.

Double slot means it takes up two spaces on the motherboard. Older and cheaper cards only use one. Really expensive ones can use up 3 slots. High point being the desired max temp.
