I got my cooling stuff in today from Jab-Tech (awesome place). Anyway I'm trying to see which way is best to mount the NB cooler fan.

Sorry, I did this in Paint. :p Mind you this is a side view with the panel taken off. Mobo is an Asus P5N-E. Red rectangles represent the fan.

Config 1. The NB cooler is an HR-05 with a fan mounted on top of the HR-05 blowing air downward thus pulling airflow from the Ninja's fan.

Config 2. Fan is mounted below NB cooler and is blowing through the fins and also hitting the Ninja from the bottom.

Is it safe to say that config 2 is better? I know airflow is being distrupted but I'm looking for the better option.
 
I'd say #2. If nothing else it wouldn't be pushing hot air towards your video card.
 
The GPU is going to have a VF900 so there will be some sort of airflow down there not to mention the bottom intake fan on the Solo.
 
I was assuming the fan for the NB was fairly small. I doubt it would disrupt the airflow noticibly.
 
I would go #2 since the warmer air from nb will be blown out the back of the case and not recirculating inside
 
#2 for sure. Also, you don't have to look at the fan size so much as the cfm rating (higher=more air of course). I have a TJ06, and essentially have 4 exhaust fans, and 1 intake "area", the fan on the cpu heatsink is about 3" in from the mounting point for the fan on the case itself. I forgot to add the two bottom fans are 120mm (don't feel like going back and editing the pic just for that :p).

*EDIT*
80mm for a NB fan=small?! I don't know where you got your info... take a look at mine, it's not much (if at all) bigger than 40mm. At times I've considered looking into an inexpensive NB cooler that was low-profile, mainly because I've read of quite a few people having their NB fans on these mobos die or become extremely noisy. But then I remember I'll have to take the mobo out of the case to do it :rolleyes:
