In looking at the Flipkart site I saw this cooler that looks a lot like the Noctua DH-14. I had not really heard of this company and living in the Usa, I can understand that since we do not get to see every type of product made, We see many but the Usa sellers sometimes stick closer to the names they know will be recognized and bought quickly. Nothing wrong with that process.
That said I generally go to FrostyTech cooler since they keep a list of coolers tested in the 'order' that they finished on their own test rig that stays the same time after time. Good 'pointer' to a coolers goodness in my eyes. Most especially when looking thru 20 or 30 cpu coolers.
Living in the East and not wanting to just spend money that I "might" not have to do, I would take a very close look at the Deepcool Frostwin. It is a good bit cheaper.
Deepcool Frostwin Testing: LGA1155, LGA2011, AM3+
The Deepcool Frostwin performs very well on all three platforms. The cooling isn’t quite as good as the top dog, but the Frostwin is lighter and also eliminates the memory clearance issues.
I found the above review and link AT FrostyTech where I always go to look at coolers as I said before. They try and stay on top of what is in the market. I liked how this review site tested and what they actually used to test with and the hefty voltages they fed to the processors while doing the testing.
Take a look you might save some money.
One more thing I need to add that is not often thought about. I feel the Noctua DH-14 really needs the added part that allows the fans to blow at the rear of the case and out thru the 'rear' case fan. That adapter does not come with the Noctua DH-14 but is available, from Noctua for sure.
The Deepcool Frostwin mounts blowing out the rear as you can see on AM3+ mobo from the pictures at this link.

At about half the price of Noctua and given the fact that tester site did not say it was totally equal to the big boys with big price tag, I might give the Deepcool FrostWin a try, since I may not ever fully and completely use the little extra the cooler that is twice as costly, anyway. The review site did test using the FX-8150 at high voltage as they did with the two Intel cpus including the new hot Intel Sandy Bridge E.
The choice of course goes to the user themselves. Although I know the goodness of the expensive Noctua DH-14, I still might give the Deepcool Frostwin a try for reduced expense and knowing I just want to use the setup and not run benches everyday. It is a thought.
