Cooling Fan compatibility

[Moowashere]

I have a Lenovo ThinkCentre A58e 0841, Pentium Dual-Core E5300 2.6GHz computer.

I have recently installed 3 PCI cards and since they can't be separated, due to limited slot number, I would like to get a better fan to keep them cool. I don't know how to tell what fan would be compatible with my computer. Would it go in place of the existing CPU fan? Can someone help?

I was looking at this fan specifically:

is your A58e a SFF or Tower format? and what sort of PCI cards do you use?
