Hi

i have motherboard p5ad2 premium with last bios ( 1010 )
+
processeur Intel Pentium 4E, 3200 MHz (16 x 200)

and i have my PC who stop (no reboot )when i have 70° Celsius

can i modify that ? and how ?

You must improve the cooling of the processor. One way to do this
is to reduce the temperature of the air inside the computer
case. Try removing the grill from the front of the computer,
and any filters used to keep out the dust - sometimes that
will allow the air inside the computer case to drop 5°C in
temperature.

How many times have you installed and removed the CPU heatsink ?
The thermal interface material on the heatsink is only good
for a few cycles before its properties degrade. You can either
try to find an Intel approved replacement for the thermal
interface material, or use some thermal paste. (If you use
paste, chances are it will have to be refreshed yearly.)

"THERMTRIP#

In the event of a catastrophic cooling failure, the processor
will automatically shut down when the silicon has reached a
temperature approximately 20 °C above the maximum TC. Assertion
of THERMTRIP# (Thermal Trip) indicates the processor junction
temperature has reached a level beyond where permanent silicon
damage may occur. Upon assertion of THERMTRIP#, the processor will
shut off its internal clocks (thus, halting program execution) in
an attempt to reduce the processor junction temperature. To
protect the processor, its core voltage (VCC) must be removed
following the assertion of THERMTRIP#. Driving of the THERMTRIP#
signal is enabled within 10 µs of the assertion of PWRGOOD and
is disabled on de-assertion of PWRGOOD. Once activated, THERMTRIP#
remains latched until PWRGOOD is de-asserted. While the deassertion
of the PWRGOOD signal will de-assert THERMTRIP#, if the
processor¹s junction temperature remains at or above the trip
level, THERMTRIP# will again be asserted within 10 µs of the
assertion of PWRGOOD."

Yup i have 2 filters , one in front and one in side case !

never removed !

hi have gigabyte 3d rockets for cpu

http://www.giga-byte.com/Peripherals/Products/Products_GH-PCU22-VG.htm

chassis :

http://www.thermaltake.com/xaserCase/Damier/v6000a.htm

thermaltake 6000a

graphic card : asus ax850 xt platinium edition pci-e ( 43°C in idle and
68 69 in load with quake 4 for exemple ) before i have asus x800 but
the ventilator of this card never run ! return where i buy it but i
loose 3 months before to have new graphic card ( x850), 3 months
without my new PC....

solutions ???

water cooling ??
ati silencer 5 rev 2for graphic card ?? but my guarantee with asus is
" out" ?
ventilator 80 and/or 90 => 120 =>more cfm but my chassis(case) accept
that ? not sure....

Or nevr buy asus ??? ;))

thx for help , i can't play with this configuration

excuse me for my bad english , i'm french ;)

The air temperature inside the computer case affects how well the
CPU heatsink can cool.

The air in the computer case should not be more than 7C to 10C hotter
than the room air temperature. If the room air temperature is 20C,
then the computer case air temperature should be 27C to 30C. Try
leaving the door on the front of the case open, turn up the fans,
remove any obstructions to air flow. Make sure all the fans are
installed.

The way the CPU heatsink works, is it has an engineering parameter
called the thermal resistance. I cannot find the value of this
parameter on the Gigabyte web site, and the reviews of your PCU22-VG
do not have a value either. The retail Intel heatsink might be
about 0.30 C/W , while a decent after market heatsink should be
about 0.20 C/W. Really exceptional heatsinks now, are below
0.15C/W.

There are various models of 3.2GHz processor LGA775. I'm not sure
which one you've got.

This one is 103 watts power dissipation:
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7LA

This model 540 is 84 watts power dissipation:
http://processorfinder.intel.com/scripts/details.asp?sSpec=SL7KL

Now, some sample calculations:

Room_temperature + case_air_rise + TDP(watts)*thermal_resistance = CPU_temp

20C + 7C + 84W*0.20W/C = 43.8C (well designed case, good heatsink)
20C + 10C + 84W*0.30W/C = 55.2C (OK case, average heatsink)
? ? ? ? 70C (fill in your numbers...)

Now, if your computer case is adding more than >10C to the room
air temperature, then you can see that the CPU temperature will
climb. Similarly, if the thermal_resistance value for the heatsink
is higher than 0.30W/C, the processor will also be getting hotter.

Your options are:

1) Improve computer case ventilation by removing filters, remove
the front door, and other restrictions to air flow.
2) Increase fan speed to its maximum.
3) Change the heatsink. Try removing the plastic cowling around
the fins, as that is supposed to improve the CPU temperature
by 2 degrees C or so.

There are many exotic cooling methods, and if you do not have
the money for water cooling, then try a few simple improvements
to your current computer case first. If you want some other
ideas for CPU heatsinks, there are Big Typhoon, XP-120, XP-90
Zalman 7700, Zalman CNPS9500, all of which are pretty big, and can
have issues with the mechanical fit of the heatsink within the
computer case.

A simple test some people use, is open the side panel on the
case, and see if the CPU temperature drops. If the CPU temperature
drops, it means your case is starved for ventilation holes.
