Hi!

First: I am very sorry for my bad English Language and hello, this is
my first post in this group! :)

I bought recently a new PC.

Motherboard: Asus P5WD2-E Premium (Bios revision 0501).
CPU: Intel Pentium 805 D.
Cooler: Zalman CNSP9500.

The bios and the Asus utilities inform that CPU Heat is over 60º C
with Zalman cooler.

I changed the Zalman for the Intel boxed cooler and inform over 50º C.

I think that is a lot of Heat. I have voltage and clock (2.60 GHz) in
auto mode.

Can you hold a hand?

Thanks you very much and best regards.

I think so too.

Clean off any and all dust from the fans, intakes, and heat sinks.

When you changed CPU heat sinks, did you clean off the old thermal
paste thoroughly, and apply a new coat?

Is your Power Supply Fan Running? Do you have any case fans running?

And, importantly, what is the ambient temperature? How hot is it where
the computer is sitting?
 
¡Thanks for your help Paul!

All the fans are new (all the components are new :D):
Power Supply Fans: Working.
Rear and Front Case Fans: Working.
GPU Fan: Working.
CPU Fan: Working.

I applied the thermal paste before install the Zalman cooler.

Then i saw that heat was very high (60º). I removed the Zalman,
cleaned the paste and installed the Intel cooler. Temp is now 50%, in
idle! Too much.

The room temp is like 26ºC.

The chase (ehm ¿pc case?) temp is like 38º.

It is very strange.

That's really hot.

There's really only a handful of posibilities.

Power supply that's underpowered for your computer.

Crappy case with poor airflow. If the case used to house an old
Pentium 1 or something, this is a possibility.

Or obstruted airflow. Any stickers or decorations blocking any of the
vents?

Or you just need an oversized heat sink.

Also look for other sources of heat near your computer.

The temperature's got to down to the mid 40 degree range under load.
 
I did this test:

1.- I removed the motherboard, cpu, cooler, ram, video and power supply
from the case.

2.- I installed it over the table. Same result:

-60ºC

I think It's not the case :(.

The power supply is 350W. The current CPU voltage is 1,3 V (Intel 805D
voltage range=1.2 - 1.4).

I tried with intel cooler and zalman CNSP9600 LED cooler.

I am lost :(.

Thanks again paul.

The CNPS9500 should do better than that. The CNPS9500
should run cooler than the Intel stock cooler. Are you
running the fan at full 12V (no FanMate connected in
the path) ?

Some of the early CNPS9500 heatsinks did not have a flat
base, and the base was concave. Have you examined the
base and is it flat ? When you apply thermal paste, there
should be a thin layer, but if the base of the heatsink is
not flat, there could still be air trapped between the
processor and heatsink.

To test for flatness, clean off the top of the
processor and the base of the heatsink, place a dot
of thermal paste on the center of the CPU, then fit
the heatsink and apply some pressure with the
fittings. When you remove the heatsink, is the
thermal paste spread in a circle ? Or does the
pattern left by the thermal paste, suggest the
heatsink is not making good contact ?

It could also be, that the thermal diode in the CPU,
is not giving an accurate temperature reading.

Do your heatsinks feel like they are cooling a 60C
processor ? Are the heatsinks getting hot, when you
feel them with a finger ? Check the base of the
heatsink, to get a good indication. Remember that
you can only hold your finger on a 60C surface
for about two seconds, before it becomes unbearable.
