Need suggestions for RAM Modules and CPU Cooler

[lahratla]

1. I have never done overclocking before. Will ocing shorten the life span of the CPU if a good CPU cooler is used?

I have a Core i3 530 Processor with Gigabyte GA-H55M-USB3 Mobo and want to overclock the CPU.

Kindly suggest a good and silent CPU cooler for the same. Is the Arctic Cooling Alpine 11 Pro good for the i3? Is it available in India?

2. Which is the best among these four? I'll be using it with Gigabyte GA-H55M-USB3 (Rev 1.0) and Intel Core i3 530. Are these RAMs compatible with the system I'm having? You may suggest if you know a better option within the same price range
