will the psu gets hotter under load?

[faye]

Hi,

will ur PSU gets hotter when it is under load?

when my cpu is idle, temp is 44C, my psu is btw cold/warm
when my cpu is loaded @58C, my psu is hot.

i have a asus p4p800e-deluxe board, is there a psu temp monitor?

thanks

Yup, a PSU does get warmer under stress, and I'm not aware of any monitor SW.

hello. i know a monitor came with a system i made for someone with a asus board. i think it was called "Asus Probe" or something like that. i'm not sure what it monitors, but you might want to check into that.

psu only puts out what is asked of it. combine with inefficiency.. the amount of wasted energy as heat goes up

i got it installed already, it monitors cpu temp, and fans speed.

Keep in mind that when your cpu is at load, it puts out heat, which then goes out through your psu. So that heat you are feeling may not necessarily be generated totally by the psu.

In general though, when your system is doing lots of stuff, it will draw more power from the psu, which will cause the psu to generate more heat.

Yup

I found that the thermal resistor on my newest PSU was keeping the RPM of the PSU fan too low. I modded the PSU fan for manual control and it is much cooler while still being quiet enough.

so did u actually open the psu and mod inside?

actually i don't feel save to open the psu, i always believe that once i open the psu, i couldn't put everything back together again.

Yeah, I got inside the PSU. The fan is usually the first thing to go on a PSU (a good PSU can usually outlast several fans) so I've become quite familiar with replacing/modding PSU fans. And it is very easy to do.
. I usually just replace the internal fan (almost always 80x80x25mm) with one of my choosing (the OEM fan usually having leads too short for my purposes) and bring the lead out thru the grommet with all the other wires. You can wire it to a Zalman fan mate (or similar) or use a standard rheostat or pot (which just takes a bit more hand work with a soldering iron).
