80mm BACK fan = (FSP300-60ATV)
120mm BOTTOM fan = (FSP300-60PN)
It seems like everyone is going hog wyld over the
Fortron 300-350w PSU with the large 120mm bottom fan.
However, after having two of the 300w Fortron models and
one 400w model, (two with 80mm back fan and one with the
120mm bottom fan) I would NOT recommend the
larger 120mm fan model.
Here's why:
While it may seem like a good idea to suck a little extra
air from the case, it's not generally a really good idea to expose
the guts of your PSU to the eXtra heat directly up from your HS&F.
Yes, the large 120mm fan might have better specs by itself.
However, once you get it situated in the bottom of the PSU the
airflow up through the components and out the back
is actually quite restrictive. And we all know how restricted air
can make a fan noisy.
The FSP300-60ATV with 80mm back fan appears
to have much more efficient airflow. Thus making less noise.
Not only that, the FSP300-60ATV netted in lower
CPU and case temps as well. The large fan was hogging air
from the back case fan.
Most importantly, all rails on both 300w PSU were
almost exactly the same under heavy load. (though the
FSP300-60ATV did have SLIGHTLY more stable rails)
