If your temps are safe and your happy then there is zero reason to change.

I think that those temps are comparable to a TRUE or Xiggy with 120's.
The 120x25 is just a hollow shroud. It(as well as the CPU is lapped, and has styrofoam around the gaps on either side of the fin arrays to direct air thru the fins instead of around them. It is a bit loud though because it isnt hooked to my controller.
