Query: Versatile, cabinet savior

I have a very small TV center niche in my living room wall. Below the TV I have a boxed cabinet that contains my receiver, my Wii, and my PS3. It gets hot in there. I bought this fan as I found the PS3 has USB ports on it. I cut a hole in the back of my cabinet and set the fan to blow across the top of my receiver. Each time that I have checked, I feel that the temperature coming off of the receiver has been cut down dramatically. The whole cabinet is not heating up as much as it once did. I think that this was a good buy.
