Modding Disadvantages of flipping a PSU

Have just received my new PSU, the Silverstone Zues 650watter!
It sure looks the part, the quality of the casing and the sleeving is awesome!

However, im wanting to flip the psu so I can hide as much of the wiring loom as possible, theres no issues with air flow as the PSU only has one 80mm fan (at the moment).

My question is if im flipping the PSU, will there be any heat problems from doing so? as hot air rises obviously but that means the heat will be rising up towards the circuit board of the supply.

Also in terms of the fan im going to replace the current one with a 80mm zalman fm1 - bit quiter but about the same cfm, if need be i will also mount one to the front of the psu casing, so it would have a push pull effect.

Any opinions??

Hi Cannon,
By flipping the PSU, I take it that you mean the rear of the PSU is facing the top of the case, as opposed by facing the rear of the case ?
If this is so, then it souldn't be any issue, as the fan's purpose is to exhaust the hot air from the PSU. The push pull system shouldn't be any issue either.

I think he means the bottomside up... But there shouldn't be any problem with any orientation, as long as there is some air moving through...

 

As long as you have good airflow I can't see the orientation of the PSU being a problem

EDIT: lol we said practically the same thing at the same time!!

 

Geniuses think alike

 

Flipping the PSU over causes no problems whatsoever.

However if you think about it for a sec, you'll realise that the default position of a PSU in any ATX tower case is with the circuitboard up (and the components hanging down from it, so to speak) anyway.

The newer BTX compatible cases often have the PSU in the bottom, and flipped over. This orientation puts the circuitboard down with components on the top. Again, no problemo.

 

You're already swapping out the default fan, so any heat increases will be cancelled out by that simple swap.

 

I do mean flipping it up side down - so the wiring loom is on the tray side.

I didnt think about that, my antec has the board ontop but then again it has a 120mm fan blowing into it.

I powered it up last night just to see how loud it acutually is - its not loud - the p4 fan on full speed is about the same - not sure what people where complaining about in their reviews.

Have given in to the noise of the psu!

Its not that loud but definately the loudest thing in my case...

The current ADDA 80mm fan in their now pushes 44cfm, if i was looking to replace this one "pulling" fan with 2 silenx 80mm's at 28cfm in a push pull config, around about what cfm would i end up with? obviously not 56cfm but at least 44?
