Over the years of use fans will wear out over time and become noisy, this is especially true for stock intel fan coolers. the only real way to fix this and i recommend you probably try to replace it quickly as this could result in a broken fan for your cpu, is to just replace it with an aftermarket cooler.

Also as a side note is your CPU running any hotter than it normally is? if you could record your temps that'd be great. if you dont know how

thanks for your help..i just bought my cpu 1 year ago or less than that..before summer when i play game like BF4 the cpu temp reaches to 60-63c max. , now when i play a game like football manager 2014 i think it reaches to 64-65c max.
so i don't know..i think 1 year isn't a long time to replace my cpu cooler..and i've heard that aftermarket coolers is more noisy than stock fans.
if i tried to clean the fan from dust would that help making the noise disappear??
Well those temps are a little high, im not sure how stressfull football manager would be on a cpu, bf4 sounds about right i suppose, Well no one year isn't a very long time, i've been using a stock intel fan for about 2 years now and its still silent as it will ever be, but there are times where a cpu fan will just crap out even after 6 months it does happen, YES cleaning can and sometimes will definitely help the problem if that doesnt work however if you want truly silent and dont mind spending a few
http://www.newegg.com/Product/Product.aspx?Item=N82E16835608018 is without a doubt the best silent cpu on the market for 1155 IN MY OPINION Its worth it though, the cpu is one of the more precious parts of your computer you wanna protect. and you either spend very few dollars and get a loud effective one or spend a few more and get a silent AND effective CPU cooler
