First of all, this is a public forum and as such we don't provide individual help. I don't understand your logic anyway. You must log onto the internet to check email just as you would need to check here. You can set the settings here to notify you of any responses to your thread.
Also, posting your email address in the open as you did invites spam. I have removed it as a courtesy to you.
Now to your problems.
Is your computer a custom assembled unit? If so, there are many different fans available. Some are much noisier than others.
If you assembled the system you may not have installed the heat sink correctly, which can cause the fan to run faster.
