Components too close together

[Him]

I was reading the specs on my buddies cooling fan, a really nice one it is. There was a little note on it, that read like this:

No motherboard components with a height greater than 39mm (1.53inch), as well as the
PSU, disk drives, VGA card, and RAM should be present within a 68mm (2.68 inch)
radius from the center of the CPU.

someone tell me why this is? It honestly dosent seem logical to me. But there is a reason for it, or else they wouldnt have said it.

Never mind, it was a stupid question and it answered itself for me. I cannot delete the post though, so it's still here. If some Mod comes along, feel free to delete this post.

HAHAH! yea sometimes if you put things close to the cpu fan it looses power... its crazy! Not shielded.
