Got this HS myself to replace my old TRU and was kinda shocked that it performed 2-3C worse then my Ultra120-A. Reapplied MX-2 as my first mount was awfull and now temps were equal to those i got with the TRU.

Decided to add another fan to it to see how push-pull would work and got a 3C drop and almost 9C in maximum temperatures recorded by Real Temp during Prime95 .

Here are some pics. Zipties FTW!

Only one fan, push:




Two fans, push/pull:
