Q9550

You really need to look at the stickies. There are just too many variations between similar systems. That's why we call them "guides". You need to know a little about what is going on, if only to keep from destroying fairly expensive electronics components.

This should be your first stop.

This should be your second stop. You need to know something about thermal management or you can fry your CPU. It's actually kind of difficult to fry a modern CPU, but it is possible.

Third stop will be a guide for your particular motherboard. Google is your friend.

You may be able to reach 3.2 GHz with the stock cooler. For anything higher, you will need better cooling. Here are two under $50 heatsinks that are pretty popular:

Xigmatec Dark Knight

They both require a somewhat different approach to applying thermal compound.

And they are pretty large, so they might not fit inside your case.

Go through the first two threads. Do not do anything until you have a good idea about what you are trying to do. Once you have definite questions (you will, you will ), come back and ask. All kinds of people will be willing to help.

Speaking of that, I noticed that although I was the first person to reply, I was the ninth person to look at this thread. I am certain that some of the others saw your line,

and decided to skip this thread.

I guess I am telling you what you should do. I am telling you that you should read the stickies.
