Hello,

I got here a brand new system with Pentium D (2core) 3 GHz and ASUS
motherboard (P5LD2, intel chipset) / graphic card (NVIDIA GeForce 7600
GT).

The system was originaly shipped here with a broken PSU, outdated BIOS
and no fans short of the CPU one. I've added a rear 12 cm fan sucking
air out (with a spin regulator set so it's not too noisy), got the PSU
replaced, updated the BIOS, and later added an extra 9 cm fan to blow
cold air towards the CPU fan and memory chips from outside.

I am testing the computer in regulated temperature environment at a
stable 23°C.

The thing is...
1. The ASUS hardware monitoring software always crashes if started at
bootup (and occasionally inbetween too) I updated the BIOS and the ASUS
software to fix that, but most of the crash-situations remain (the
monitoring software starts running really slow, like one window update
per minute, and End Task doesn't make it go away). Also, with this new
P5LD2 BIOS from the ASUS website, the "System Monitor" area in the BIOS
doesn't work anymore (tho the Windows-based monitoring software works a
bit better).
2. When the computer comes back from being idle a long time, the
taskbar area is black and doesn't redraw unless clicked upon.
3. The motherboard temperature is 40°C... it was 46°C before I
installed the extra 9 cm fan.
4. The CPU idle temperature is 50°C ... 60°C before I installed the
extra 9 cm fan and it skyrockets if the CPU is in use. This is while
Not using the ASUS AI NOS feature or otherwise overclocking the CPU.

Is all of this normal / to be expected?

The ASUS PC Probe || monitoring software declares the motherboard over
45°C and CPU over 60°C as warning temperatures. Is this reasonable?

I would like to bring down the temperature of the CPU to something that
wouldn't cause all off the alarms going off durring normal usage,
however I already installed all the possible fans around it. What can I
do to bring down it's temperature further?

this sounds like a bad bios flash, which would affect all things
monitoring/using it for information..

None of the above sounds right. First, the motherboard temp is
too high, esp. for an ambient temperatue of 23°C. This indicates
inadequate ventilation into the motherboard area and the side fan
working with a single exhaust fan might not be sufficient. Add at
least another 120-mm. fan to bring in more air in from the front
of the computer case. A "thermal advantage" computer case is a
mandatory requirement for the Pentium-D.

While the Pentium-D Core Duo CPU's are known to run hot, and
some of the 3.4 GHz units idles at 50°C over a motherboard that
is at 30°C, they do require very good HSF's, at least with 130 W
capacity. The stock Intel HSF's might not be good enough, esp. if
the contact between the heatsink and the CPU is inadequate...what
a lousy push-pin mounting design, IMO. There are some very good
third-party HSF's, e.g., Thermaltake or the Asus "Silent Square".
Under moderate-to-heavy use for a 3.0 GHz Pentium-D CPU should not
be setting off the alarms, since the CPU will throttle back.

The solution might be to upgrade the computer case to one that
meets the "thermal advantage" requirements (check the Intel
website) and configure it accordingly to work with the CPU.
