Actually absic if you do the math there is a considerable difference in area betweeen the two sizes, however I would agree that I wouldn't expect a huge difference in real world temperatures.
I did the maths and I still reckon not too much room for overall improvement from the slightly bigger fan.
So the moral is be happy with current setup
There comes a time when we all have to say "I have tried my best" and remember the real reason why we have a computer.
Yes, but we are all the same aren't we? Never happy unless we are fiddling( or guitaring in absic's case )
Oh, I've done my fair share of fiddling....... tromboneing..... piano playing........... etc., etc.
