Temp increase, is this normal?

[ksherman]

I just got a new PSU the other day. Replaced the Stock Antec PSU (came with Sonata) and replced it with a Seasonic S-12 500W. Everything else stayed the same in the compy, but i noticed a sizeable increase in Temps accross the board.

My CPU used to Idle around 30-32C, now idles around 37-39C
load used to never go above 50C, now goes close to, and sometimes over, 60C

My GPU used to idle around 40-43C, now idles around 50-54C
load never got over 55C, but now goes very close to 70C
not only that, but that is with the Fan turned all the way up (Zalman VF700 with fan
mate2)

Chipset used to run around 50C or so, but is now runing around 60C or so and the fan is constantly spinning up and down...

I dont have any solid numbers, but it seems as though my HD is also running a little hotter, as well as the internal system temperature. This all seems a little odd, as the new PSU has a fan on the bottom that is helping to remove air form the area around the CPU. I also used to have a 120mm rear exhaust fan which I no longer have plugged in with the new PSU, as the fan runs at full speed and is very annoying (the Antec had fan connectors that undervolted the fan to make them quieter), but even when i did plug it in and let it run for a while, temps didnt move much.

I dont really know why this is happening. Is it possible that before, the components all werent running at capacity?

System specs are in my Sig

I'm doubtful about the "system not running at full specs", the PSU that came with the original Sonata only had 18Amps on its single 12V rail, so that wasn't very impressive, but you should have noticed powerdowns or so whilst gaming...

In fact, the Sonata is a little cramped, and with such high-end hardware built in, it doesn't seem odd that your temps are quite high... Although, before you switched the PSU, your temps were actually below average... A 7800GT that doesn't exceed 55°C under load is a rare breed IMO, even with a Zalman... The 70°C figure looks a lot more realistic to me... Your CPU doesn't look too bad to me either...

You could always have a bad sensor too, are those figures from MBM? Otherwise, it could be that a BIOS update solves it... That's happened before...

I would also look at the monitoring end. But if you didn't change anything else in the configuration, and the temps went up, something is going on.

Maybe the Seasonic is for some reason not running its fan fast enough? Do you have intake fans in that system? Just having the PSU fan going is unlikely to cut it with a 7800GT in there.

Is it possible that before, the components all werent running at capacity?

Um, no. Either your parts work or they don't; your CPU isn't going to magically underclock itself if your PSU can't put out enough wattage.

well, my Antecs PSU had 26A on the 12V line... Well, i do plan on getting some aditional intake fans. I am researching as it is importnat for this machine to be as quite as possible. the antec PSU came with those Fan power connectors which slowed down the case fans so they were very quiet, but the seasonic has no such feature . I will probalby buy two Nexus or Yate Loon 120mm fan (one for exhaust and one for the HDD) since they seem to run very quiet...

Panaflo's are an option too if you want it quiet... If you can find them in the States at a reasonable price, Papst is a good alternative as well...

You're right, there has been an update where the Sonate got a better PSU, my mistake...

Definitely plug that 120mm fan back in. Without any half-decent exhaust for the case, the hot air's all being drawn into the PSU and there's a limit as to how much hot air it can actually exhaust.

 

[imported_Phil]

Oh yeah, and if it's too noisy, then get a Zalman resistor cable for the fan- slows it to 7v.

The bits in bold are the important ones, if you disconnect the huge 120mm fan thatis probably pushing 35CFM out the back of your case and then expect the PSU fan to do the job then you're dreaming (or need to think a hell of a lot more about what's going on there)

I know you tried plugging it back in, but try booting up from cold with it connected again, you should find that the temps never climb up to that level. If it's too loud at 12V then you can easily mod it down to a lower voltage, use google for that, or buy a fan controller.

Everything stayed the same.... EXCEPT FOR THE GIANT FAN THAT I DISCONECTED!

Seasonic's PSU are relatively quiet because they have high efficiency, it means less heat is produced in the PSU, and therefore the PSU fan can be spinning at a low speed. The side effect is that it would be pushing much air out of your case.

yeah... lol

well, i just did a quick mod and set the rear fan to 5V... muich quieter and temps are closer to normal... but i also JUST turned the computer on
