Power Supplies and the P4P800

I just had to put in a new power supply. I bought a good quality one
with a sensing fan in it. That's great, now I can monitor the fan
speed. I was hoping as well to monitor the PS temp, but perhaps my PS
can't do that.

For temp monitoring I've got Case, CPU, and HD.

For fans I've got the Case, CPU and PS.


For interest and comments, here's what I've got for fans:

Lower front standard case fan.

Top front bay fan set of 3 small fans.

Rear small case fan above slot area.

Rear slot fan beside the video card.

PS fan rear top.

All front fans suck in.

All rear fans blow out.

Temps:

P4 2.66 CPU: high of 52 while playing BFV.
MB high of 42, room temp 70 F.
HD high of 45.

I used thermal CPU grease called Unic, removed dumb pad on the P4
(changed MB) and have stock fan. After using the thermal Unic, my CPU
temps went down 7 degrees or so.

Motherboard Monitor 5 something, used the P4P800 setup.

My setup rocks now with the Radeon 9800 Pro. This has it's own fan (no
idea why I can't monitor that fan and it's temps also) and I have the
slot fan beside it. It feels cool to the touch always.



BTW, Raccoon cases and PSs suck, stay away.

Does anyone know if I can monitor anything I'm not now on this system?
PS temp? Video card fan or temp?

I have an older Asus CUBX- E that came with an extra temp sensing
diode probe. I used to use that on my video card. I wish there was
somewhere I could use that on this MB. Forgive me, my owners manual is
all Japanese, perhaps I'm missing something.

 

There is a header on the board labelled TRPWR1. It is between PCI slots
3 and 4, on the right hand side. If it is like other Asus boards, the
TRPWR1 two pin header expects a 10K ohm NTC thermistor, with a beta
of (maybe) 3435. Most likely, the sensor from your old system will plug
in there.

If you have an ohmmeter, the thermistor resistance as a function
of temperature will look like the following table. This table
is for a Radio Shack part which is no longer sold. If your probe
wires ever get shorted, the resulting temperature reading will be
higher than 110C in the table below.
