Power supply Fan

[Mike]

I have a Coolermaster cac-t05 case
And I want to install a modular power supply.
The problem is that all of the power supplies
that have the features that I want, have a BIG
cooling fan located on top. My case does not
have enough room on top for the fan to take
in enough air. I can get other power supplies that
have the smaller rear fan, but I really don't
like them. I was wondering if I can just cutout
the top of the case, so the fan can pull in fresh air
directly from the outside of the case ?
Has anyone ever tried this ? Is it worth the trouble ?
I don't mind the extra work. The only other thing
I can think of is to install the power supply upside down,
and just redrill some new mounting holes.

Allot of folks here have much more experience
at this than I do, so I ask for your help and
experiences. Thanks for your help

Mike .

A great many people have cut holes in the top of their cases, called
blowholes by case modders, to increase the number of fans with access
directly to the outside of their cases. A google search for blow hole
and case mod should give you a good starting point. To cut this hole,
depending on the size of the fan (probably 120mm, yes?) you'll use
either a hole saw, a dremel, or a nibbler (this last one being far from
ideal, and only mentioned for completeness).

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:

not going to mention the metal shavings, eh?

the fan faces down towards the CPU...most pictures of PSU's show the unit
upside down

Why? None of the sites he'll be going to will demonstrate this with any
hardware in the case, and almost all will have cautions for those who
need the 'do not eat' warnings on the baggies of dessicant and tubes of
preparation-H.

I'm not familiar with the PSU in question, but for large midi and
full/maxi tower cases there's air above the PSU, and this PSU
manufacturer may have decided to suck air from there rather than the hot
air coming off the PSU. I assumed the OP was bright enough to figure out
which way up his particular PSU went...perhaps I assumed too much?

I too suspect the OP may be confused by the pictures offered on the web of
various power supplies. For instance, I have the Neopower 480. Look at
this picture:

One would think looking at the picture that the PS mounts with the fan
facing upward. In practice though, the PS mounts into the case with the
large fan pointing down into the interior of the case where it sucks air
into the PS and exhausts it out the back. Might be helpful if the OP
mentioned some of the specific PS's he's considering...
