I've been playing around with my Solo quite a bit lately, changing heatsinks, fans, ducts... So I figured I'd start a new thead for the updated rig

System specs :
- Antec Solo with Scythe Kama Bay (no fan)
- Enermax Modu82+ 625W with the fan swapped for Noctua NF-P12 @1100rpm (9V)
- Asus P5QD Turbo with HR-05 sli on Northbridge (original one is really bad)
- Intel E7200 @ 3.2GHz with Mini Ninja (no fan)
- Corsair 2x2Go XMS2 DHX
- Gainward 9800GTX+ with HR-03 GT with Nexus 92mm fan @1500rpm (12V)
- Intel X25-M (V2) 80Gb for OS + programs
- Samsung 1To in SQD for storage
- Exhaust fan NF-S12 @900rpm max (9V) temperature controlled
- Input fan Nexus 120mm @1000rmp (12V)
- Major ducts

There are 3 ducts in the system:
- One on the Ninja : to separate the airflow for the exhaust fan and the PSU fan (so they don't fight for air)
- Two for the Nexus 120mm intake fan :
- One for the northbridge : the original NB heatsink got so hot it was impossible to touch (Asus' clever design is not that clever after all...) so I replaced it with an HR-05 I had laying around. That was much better but I figured a bit of airflow wouldn't hurt. Also, this duct helps cool the underside of the GPU (the top of the card).
- One for the GPU : the idea for this duct is to make a separate chamber just for the GPU : some air flows through the RAM/VRM heatsinks, some air is used by the 92mm Nexus to cool the HR-03 GT , and all this warm air is ducted direcly to the outside of the case
Some pics :
General view : General view without main duct : Exhaust fan, PSU fan, Minja duct : Intake fan (through the fins, the HR-05 and HR-03 GT) : HR-03 GT and GPU exhaust, without duct (PCI slots cut out to facilitate airflow, but ou can still use the screw holes to attach the expansion cards) Worse temps on full load (with 25°C ambiant), CPUburn x2 and rthdribl :
CPU : 51°C
GPU : 65°C
Usual temps while folding :
CPU : 47°C
GPU : 60°C
A few notes about load temps :
If I remove the main duct, the GPU temp drops 5°C (!) but the exhaust fan ramps up to full speed (900rpm), the PSU warms up, and the CPU temps jumps 6°C.
With all the ducts in place, if I open the door of the Solo, the CPU temp drops 2°C (49°C) and the GPU temp drops 7°C (58°C).
All comments/suggestions/questions are welcome. Enjoy
