Have any of you set the Fusion or the equivalent NSK case up in this way? Did you have any problems?
I'm running an AMD BE-2400 with a Minja, and no fan inside a Fusion 430 (although 2 exhaust case fans - a Scythe Kama PWM and a Noctua 120mm - both running under Abit EQ fan control).
CPU temperatures are about 29-30 Celsius idle, 50 C under load. System temps are about 31 C idle, 35 C under load. GPU temps (8600GT passive cooled) are 45 C idle and 50 C under load.
In short, I wouldn't worry about the lack of a direct CPU fan. The airflow in the Fusion will take care of things - although block up the inlet holes next to the case fans so that it needs to drag air over the PCI area, so the GPU temps are lower. If I don't do that, the GPU temps jump by about 7-8 C.
Only problems are in actually fitting the Minja onto the AMD mountings. God, that was scary. I really thought I was going to snap either the motherboard or the tabs on the Minja. But both are made of tougher stuff.
