Lian Li PC-9N Review @ OCC
 

"The CPU and GPU idle temps for the PC-9N were as expected. Under a load is where things surprised me. I might have to rethink my view point on multiple fans. I really expected this case with just one front intake and rear exhaust to run hot. More fans are better, right? Well, not so fast. Both the CPU and GPU were kept at the low end, in fact, for the CPU it was the lowest of the cases I have tested. No top fans. No side fans. And the front 140mm fan is pulling air through what seems to me to be a rather small front vent panel. Clearly the case has adequate air flow. And with fewer fans, it is on the quiet end."
