Where i can get a heatsink without fan for a 540 sized motor in INDIA? Need it for my XXT ripper 3300kv motor. Preferably aluminum in blue colour.  

Also is there anything specific i should look at apart from the fitting to decide which heatsink to buy?  

In a heatsink,more surface area=better heat dissipation.Usually,they are finned.

If you want,you can ask a machine shop to make one for you.

heat sinks are available in computer parts shop.....
these are used in cooling fans...

Thanks guys. Will check But i would prefer buying a ready piece of the net due to lack of time.
