Powersupply up or down?

post #1 of 19
Thread Starter 
I have the Antec DF-85 case, and tonight I was redoing all my cable management, and I decided to flip my PSU so the fan faces down, as it made the cable management a lot easier.

Now I was wondering, is it a good idea to do this? The case doesnt have any vents under it for the air to be let out, but the PSU is raised a couple of centimeters off of the bottom of the case, whic I suppose would provide airflow, but is it enough?

I have the CoolerMaster 700W Silent Pro PSU.

It will be fine. As long as there is airflow around the PSU so that it can get under it to the fan.

THere is only about a centimeter or two of space under it, is that enough space do you think?

Should be plenty...hold your hand or a book that far infront of a case fan and you will see it can put out planty of air yet.

It might be louder though.

It should be plenty of airflow, but what do you have for a CPU and a video card(s)?

Well, its running as quiet as usual, (Or close enough that I cant tell) so I guess that means its ok.

Do PSUs have safety shut offs if they get too hot? Like I know my CPU and GPU will force a shut down if they over temp, but I never thought about a PSU doing it.

Oh cool, then this is even safer than I imagined because of the low load on the PSU which makes for low PSU temps (which means it's all good).

I suppose a noticeably louder PSU fan than usual, but that might be it. It sounds like it's going to be a worry-free setup though.
