Hot or Not? MB & CPU target temperature.

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

Hi Guys,

I have a quick question.
I recently built my dream PC and finally managed to install XP on it
(thanks to this forum). This dream PC is a SILENT PC, it just does not
make any noise. A lot of PAPST 120mm fans and Thermalright helped me
to control the silence.

Now I can monitor the temperature of my PC, and I have absolutely no
idea if it is too warm or not.

Standard: (Word, IE, Excel etc...)
CPU: no more than 51 celsius.
MB: no more than 32 celsius.

Hard: (Chaos Therory 1600x1200 full res, iTunes running, and DVD to
Divx encoding)
CPU: no more than 67/68 celsius.
MB: no more than 38 celsius.


I looked at some great website who are testing PC cases, but I am not
sure how long can you have near 70 celsius in your case. This is damn
hot!!!

Thanks for your answers.

Hi Jc,

Almost 70c sounds hot for your CPU. I'm interested in that answer
myself. I did find this page:
http://www.heatsink-guide.com/cont [...] temp.shtml

..... which states tha the max temparature for your a P4 cpu is 64°C -
78°C (check your processor documentation for the exact temp.). p4s
also 'slow down' when overheating, so they don't burn out, they just
run very very slowwwww...

The video of Tom's Hardware is cool. Another reason to stick with
Intel, they slow down when overheated instead of burning. Though I
should say that temperature of AMD is pretty high. Enough to cook a
good old turkey!

Ok for AMD.
I looked on the Intel website and I found the following doc that
specified that a P4 540J should not run above 65 celsius. This is
pretty low!!!!

I also found the general Intel specs.

Looks like I need to increase my fan speed..... That's bad, I am losing
silence down here...

68 C is VERY warm for long term use. It is prematurely wearing the CPU.

For the AthlonXP boards, Asus added "Asus COP" - CPU Overheat
Protection. On a A7N8X board, that is implemented with a
Winbond 8 pin chip. The chip monitors the thermal diode on the
processor die - a threshold of 85 or 90C or so is used by the
chip, and it will signal a shutdown if the temperature goes too high.
I think Attansic may make a chip like this as well.

At first, Athlon chips had no protection. The first CPU overheat
circuits designed, needed help from the BIOS, and there could
still be issues where the processor gets hot fast enough,
that the BIOS might not initialize in time. After that rocky
start, the trick with the eight pin chip began to appear.

The eight pin chip can respond fast enough, that no matter how
you knock the heatsink off the processor, it will be in no
worse shape than a P4.

Athlon64 has a pin labelled "THERMTRIP_L", which has a similar
function to what a P4 has, in terms of detecting abnormal die
temperature. So, it is likely the little eight pin chip is
no longer needed on the newer AMD boards.

If there are any videos left on Tomshardware, it is
time to throw them in the trash.
