Wouldn't the strong airflow carry all the debris out of the case?

Ok, so recently I decided to take this Utility fan that I normally use to help me sleep and I pointed it into my case to see if I get a decent amount of temperature difference from what I would have without it. Yes, it is really loud but I when I wear headphones I don't hear it. Turns out I get about 3-degrees cooler on my CPU and a whole 4-degrees lower on my GPU. Is this a healthy thing to do to your PC? I'm guessing that it really isn't but I'm honestly not a wiz at this sort of stuff so I was wondering if anyone else can give me any sort of reason not to do this for cooling performance?

I had a question as to a different method towards cooling the water that enters through the radiator back to the reservoir. How much more efficient would it be, and would we have the technology available, in order to refrigerate the water in the reservoir outside of the case instead of keeping a reservoir inside with an attached radiator that cools the water before it passes through the CPU water block. Would there be an efficient way to do this?

LOL I don't even know the specs to my first computer. It was one of those Dinos that had a VGA cable as a tail. Handled Warcraft III decently though. After that I got used to my secound computer which had a Pentium 4 processor and then an integrated graphics card + Windows Vista. Vista can kissta my a** goodbye.
