I’ve seen this question asked quite a few times, and figured I would shine some light on the topic.

First of all,  you shouldn’t be searching for this exactly.  You should be searching for a fan that fits the socket type of your CPU, but since you did search, I am going to assume you don’t know what that is.

The easy solution would be to buy a CPU Fan or Heatsink with generic mounts, but that won’t offer the best selection, and definately not the best preformance.

To determine what socket our CPU is, we will use a program called CPU-Z.  You can download CPU-Z here.

Once you download CPU-Z, and install it, start the program up.  After the loading screen finishes, you should see something like what I have below, but with different data.  You should see the red area below as well.  This contains your CPU’s Socket.

Now, you are ready.  Go back to google and type in CPU Socket ___ Fan.

If you need help choosing a CPU fan, I recommend you read this post:
