Cooler Master 700 PSU- which way does the fan go?

Hello Wise Ones!
I'm in the middle of building my first machine, and I'm modding an old Compaq ATX(ish) case (I want a desktop case, and new ones are too small to fit everything and get good airflow).

So, I'm cutting the case to create a mount for my Cooler Master Silent Pro M700- which way does the fan go?

I'm assuming that the fan sucks air from inside the case and exhausts it out the back. I've seen some pictures of builds where the fan is oriented to the top/bottom of the case. Is this correct, or should the fan point towards the inside? Does it matter?

Thanks!

The big 135mm fan on the PSU draws in "cool" air to cool the PSU and exhausts it out of the back of the case, right?

It draws air into the psu, wether warm or cool depends on a few things, the mounting having the greatest influence.


Photos 1 and 3 show a top mount , drawing air away from the cpu, that's likely to be warm.
Photo 2 shows a bottom mount in what I would hope is...

Well, its a desktop case, so I'm mounting it on the right-hand side... but if it were on end, it would be at the top of the case. Either way, you're saying that the intake fan should point towards the motherboard right?

ok, not to beat this to death, but I'm still unclear.

The big 135mm fan on the PSU draws in "cool" air to cool the PSU and exhausts it out of the back of the case, right?

So, if I point it towards the mobo, isn't it going to suck up the hot air coming off the my CPU?

Also, in the pictures I've seen of it installed:

All show it with the fan pointed towards the case, and away from the mobo.

This isn't to say that these people aren't wrong, but since I've got to create a custom mount for this thing- I want to get it "right" the first time.

Photo 2 shows a bottom mount in what I would hope is a vented case, that would draw cool air into the psu and isolate it from the system cooling.
