CPU Temp Probe Location?

Nice ... I'll have to pass that one around at work

Depends on what your goal is...

Since the P4 has it's own on-die thermal diode that takes far more
accurate measurments than this add-on probe could hope to, I'll assume
you want it to control the heatsink fan speed.

Bore into the side of the 'sink base with a drill press, at least deep
enough that the entire probe can be inserted but no larger diameter
than necessary. Use a toothpick (or whatever) to fill the hole with
arctic alumina epoxy, insert the probe and wipe off the excess that
squishes out, hold the probe fully inserted so the tip contacts the
bottom of the hole till the epoxy hardens a few minutes but wait
several hours till it's fully hardened before moving or using it. Of
course this is a permanent solution, I'd be doing that to a better
heatsink than the retail one, but to each his own...

Actually I only need it for a digital LCD read-out that came with my new
case ... It won't control anything. I was just thinking using some thermal
tape and attaching to the bottom of the heat sink right next to where the
heat sink surface meets the CPU and assume an extra 5 degrees C (because it
won't be fished in though the CPU pin connectors and sandwiched under the
actual CPU as some sites have shown).

Or would my idea be way too far off the mark?

If the sensor is thin enough, and if your tape allows a good thermal
contact with the 'sink (which I doubt it would but you're left with
little alternatives if you want a non-permanent solution), then you
might not get an instantaneously accurate reading but close to an
average if you do consider an offset from the actual temp as you
mentioned. However I'd expect that offest to be a lot higher than 5C
at full load (compared to the on-die sensor) but I couldn't speculate
about how large the difference would actually be.

Since your motherboard likely has a mechanism to report CPU temp
already, you might use the sensor for something else like the HDD or
video card.

Right ... good idea regarding the video card .... Thanks!

HDDs have their own sensors so don`t waste it there.

One might not wish to use the system sensors, but have a
sensor/thermal management system wholly separate from the host PC
system.
