Antec Truepower and cabinet cooling issues

[coolsti]

I just received today all the individual parts to the upgrade of one of my
current PC's, and now I am wondering if I am going to have cooling issues.

The PSU I selected is a 480W Antec TruePower 2, and the PSU fan on this
model is located on the top (or bottom, depending on how you look at it)
rather than on the real panel. I am upgrading an HP vectra VL800 by
retaining only the minitower and replacing just about everything else. I
want to re-use this cabinet because mechanically, the cabinet is of superb
quality, where everything snaps in and out and is easy to work with.

But the cabinet only has one fan in the rear. And I am wondering how I
will be able to mount the PSU. Seems to me the PSU must be mounted with
its large fan blowing downwards inside the cabinet, whereas all my other
PSU's with the rear mounted fans can blow directly outside the cabinet.

Is this a hopeless situation? Am I going to have extreme difficulties with
cabinet cooling? And what is normally done with a PSU like this Antec
Truepower 2 without a rear mounted fan? Are they usually mounted to blow
inside the cabinet, or is it expected to be used with a special cabinet
with a fan hole so that the air can blow directly out?

Thanks for any help!

That's an *intake* fan. Air still is taken from inside the cabinet and
blown out the rear panel of the power supply. By mounting the fan as
an intake fan, rather than an exhaust fan, it reduces noise.

No, you shouldn't have any cooling problems with this PSU. I've used
various true powers in various cases, they have all worked very well,
and very quiet due to the variable speed fan.

Mount the PSU with the fan facing the CPU.
The fan on the PSU will suck air from inside the case and blow it out of the
back.

And I feel a bit dumb now!

Actually, I took out the Antec unit from its box to have a look, and I
guess I focused so much on the large bottom mounted fan, that I overlooked
the fact that the rear panel was just a grid so air could pass through.

Thanks for the very quick responses, to both posters that replied so far,
and for the help! Now I feel a bit better about going ahead and trying to
assemple all these bits and pieces.
