I remember you. Since you reside in India, high ambient temperatures make stock cooler quite useless - I had the same issue with my i7-2600. It's normal, but on medium to heavy load your CPU temperatures will go all the way up to 80 degrees Celsius or even higher, and that's not good. Get a Cooler Master Hyper 212+ cooler, it should be about Rs. 3000 and I'm very happy with it: 40C on idle an maximum 65C on heavy load.
