The SSD on which Poser is installed is between the video card and the 3 fans on the bottom...

Not sure that one day  I will be able to understand what engineering means... I mean: that's a true  evidence: it's one of the worst position, especially since the video card manufacturers insist on having GPU's fan directed downwards

And for what concerns Poser's speed when a scene is loaded, here are some parameters you should consider:

I keep the preview resolution up to 4096, which is the size of most bitmaps I use. And ono the left (hardware shading supported) I keep these options and settings.
One parameter that I've never understood the meaning: PBuffer or Scene Window.
