Hot PSU

[lawro2001]

I do not know if this is normal or not but I have a 700w psu and it gets quite hot. at idle it is quite hot and when the cpu and gpu are at full load it gets very hot. I don't think its just hot air being pulled from the case because its only hot when I feel the top of the psu (where the components are)

Do you have it sitting on a floor (EX: Carpet?) 

[lawro2001]

no, it is in a fractal design core 1000 case that only has support for top mounted ones

If the PSU on the bottom with the fan facing down, and it is placed on a carpet, it will not be abe to pull any air in.

no its not, my case only supports top mounted

lets put it like this: (rough estimates)

 

guessing your system pulls 600 watts on full load, and your power supply runs at 85% efficiency, that gives the following:

(this isnt how this works, but its good to give a generic idea)

600 watts / 85 * 100 = 705 watts pulled from the wall. (note: the 700 watts listed isnt the "pulled from the wall" but "pushed into system" wattage)

the difference between those is 105 watts, which is heat.

those 105 watts are pulled away from the system by a fan.

 

can you touch the PSU? if you cannot hold your hand on it anymore, that means the casing is over 70°c (a teacher told me this fact once, its quite a good rule)

if its over 70°c, something might be wrong, but at a high load, high temps just come with it.

What PSU is it?

[kronickiller]

your probably getting close to maxing out your psu if ur running sli and maxing everything out

yes I can touch it, but its much hotter than it used to be and I doubt a q6600 and a radeon 4890 can max it out

have you checked for dust? the more dust is in there, the less of those watts of heat can get out.

[lawro2001]

What PSU is it?

its an old recased antec one from 2009 that I don't think is sold anymore

yes I was just looking for that the other day just tomake sure that wasn't the problem

[lawro2001]

I don't think It could be the case temps because the cpu only gets to 60 degrees c

When it was recased was any of the airflow path changed?

[kronickiller]

well if ur psu is on top its gonna be sucking in all the hot air from your processor add in that card which is hot as hell lol , how is ur exaust system on that system

[lawro2001]

When it was recased was any of the airflow path changed?

no, its always been the rear exaust style

[lawro2001]

the only thing I could think of is me having to swap out the fan last week because the old one was dying

what do you mean by exaust system

[flibberdipper]

Sounds bad. Even my EVGA unit with a heavily-OCd G3258, Radeon 7950, and GTX 480 all running OCCT small data sets and Furmark made it warm. Even though the fan in mine is super loud (air woosh) so I'm considering selling it and trying to get something better.

[Redsun20]

Is there any other way that the hot air is being pushed out of your system?

[Slash003]

The place where das hot air leaves

I might just get rid of this supply and get a new one because it is getting old now

[lawro2001]

Oh, I have a 120mm intake on the front and that's it

It's not a bad idea.

[lawro2001]

Is there any other way that the hot air is being pushed out of your system?

no, I only have a 120mm intake at the front bringing in cold air
