P4 & mobo temperature

[Guest]

Archived from groups: alt.comp.hardware.overclocking (More info?)

What about 47°C for a P4 3.2Ghz overclocked at 3.5GHz and 43° for ASUS
P4P800SE mobo ? Is it normal ?

What is the temperature limit for a P4 3.2Ghz ?

What is the usual overclock limit for this kind of CPU with Kingstone PC3200
DDR RAM ?

Are the figures in stressed situation or idle?
If idle, they seem to be too high ! They typically should be about 5 to 8 °C
above ambient temp for the motherboard and 8 to 10 °C for the CPU.
In stressed situation, add 10 to 12 °C for the CPU, and 3 or 4 °C for the
mobo. Figures however could vary depending the measuring method and the
installed components (and of course the case and cooling).
Typical limit for (stable) overclocking should be +/- 245 MHz fsb with mem
set at 5:4 (assuming good standard cooling).

Really? I figured if I keep my 2.4B processor under 50 degrees under full
load (with no overclocking), I was doing pretty good. Since room
temperature is around 20, that's a total of 30 degrees above ambient. I
don't think I've heard any warnings from others about keeping it under 50,
unless you want lots of room for overclocking.

My MB creeps up to 37 to 40 under full load, if I leave it run long enough.
Personally, I figure the OP's temps are fine.

About the mentioned figures, I said they were "typical", and that doesn't
mean they can't be higher, without being "unsafe". As long as they remain
under the manufacturer's specs.
However, I believe your temps are rather high, and idle temps of 45 to 50 °C
are too much, although not unsafe. In your place, I should review the whole
cooling. I think your case should be better cooled, for ex. by adding a fan
at the bottom front, if possible.

First off, I'm not getting idle temps of 50 degrees, I'm getting load temps
of about 47. Idle temps are around 35 to 37.

Second, I've got my system in a desk drawer right now. To get the cooling I
wanted, I've got a PVC pipe with a 45 degree angle pointed directly into my
Zalman 7000Cu HS. This PVC pipe has a 80mm fan blowing room temp air
directly in the heart of the HS.


As far as I can tell, this is as cool as the system is going to get without
putting it directly on the desk with no case whatsoever.

Your post says that CPU temps should be 8 to 10 degrees above ambient at
idle, and an additional 10 to 12 degrees at load (total of 18 to 22 degrees
above ambient). Given a room temperature of 20 (for the sake of easy
figures), that would make recommended idle temperature of 28 to 30, and a
load temperature of 38 to 42. While those might be nice figures to strive
for, I'm pretty sure they're not "typical" on modern processors, unless
you're water cooling.
