I am looking for a silent 80mm fan. I saw one from CoolerMaster which costs 250/-, but not sure about the noise it produces. I am looking for a fan which is very silent like the laptop fans, but in 80mm w/ good air flow. This is for my projector, the default fans are very noisy. How much a good silent fan costs? How good is the coolermaster fan, are they silent to the extend which i am looking for?

Considering it is for a projector:
Projectors cause a lot of heat. You need to see the minimum CFM ( Cubic feet per minute - Wikipedia, the free encyclopedia ) required for your unit first.
There are many low noise fans in the market, but the noise reduction almost always is at the cost of volume of air being circulated.

It already has two 80mm fans (air out) and and a 40mm fan (air in). I wanted to replace them w/ the silent ones. I forgot to check the cfm, will try to find it today.

I have a projector that's noisy too, but I wouldn't risk changing the fans. The lamp generates a lot of heat and could possibly blow if it is not evacuated properly and cost a lot to replace. If space exists, what I would suggest is to get 92-80mm and 60-40mm adapters and put larger 92 mm and 60mm fans that evacuate and push the same amount of air respectively but spin at lower rpms thus reducing noise. Don't know if such adapters are available in local computer shops.

THe CM fans are very silent but only at their stock rpm... you should check out the CFM before changin... :)
