I bought my PC from Novatech in 2007 as a "bare-bones-bundle" (mobo -
case - memory). As yours, it has the "funnel" directing air to the CPU
cooler fan, another fan in the PSU, and a third 120mm fan screwed inside
the grille below the PSU blowing out of the case. This fan is connected
to the SYS_FAN header on my mobo. I haven't experienced any issues with
overheating but this wasn't a top-end model even back then.
Hope that this is of some assistance. I can send you a photograph of the
internal layout of my PC if that helps.

P.S. Looking at the amount of dust that accumulates inside my PC, it
looks like a very cost-effective alternative to running a Dyson,
particularly as this is internet-enabled.
