Idle / Load processor temperature variance

[goldfries]

It's like this, many years of using computer and testing idle and load temps - i've never come by idle vs load to having like 35c apart...........that is until i use newer AMD processors.

my Athlon64 and X2 3600+, both show an idle temp of around 35c or so and load temps that could easily touch 70c or more.

do any of you face the same thing?

btw my boards are both from Biostar (6100-M7, Tforce 550), i can't remember the readings from my DFI Infinity N4x(that kept dying on me) and my ABIT NV8 though.

I can think of a number of factors:
1. It depends on the cooling efficiency of the heatsink. Usually, idle temperature does not differ that much on various heatsinks.
2. That's because the idle implementation is better and more efficient (AMD Cool’n’Quiet)
3. Despite the die shrink, processors are still producing a lot of heat, which is why load temperature is a lot higher.

Hey there,

My idle/load for my X2 3800 is 30/50 for un-overclocked settings.

Like Chai said, it could be of these factors.

Or those Biostar boards sometimes have freaky temp sensors, like my Biostar 6100 AM2.

p.s: My Celeron D also having the same problem, but it is actually the temp sensors that are freaking out, so I used a different software for it. But you can judge the temperature physically by touching the HSF. If your hand suddenly jerk out in response of extreme heat, the processor is definitely overheating. If you can grab it, well, it's the sensors.

I agree.

now the only thing i'm waiting for is my AM2 bracket so that i could mount my scythe ninja and compare my A64 with my X2.

Please check your heatsink mounting.
As long as u enabled cool and quiet, the heatsink is virtually useless because your CPU works at 3-5W only. Any HSF will give you almost identical idle temperature.

I have a non-overclocked system with new fans on the case and processor and I am still have issues with heat. Mine are as follows;
Power Supply-36C
Processor-56C at idle, 80C +++ running any game
Case 38C
HDD 37C

I ca n not get my processor to run any cooler.

Is it a Pentium 4 Prescott?

Looks like a presshot.

Well you need better cooling. Good airflow in the case helps a lot as well.

I added another case fan and directed it (out Flow) from the processor. At idle I am still running 54C. Should I redirect the airflow? I am lost on this one. I also changed my processor fan to be certain that was not a problem. By the way, this same system used to run around 40C idle and 55C on a game program, I can;t figure out what may have happened.
