placing temp probes, need help

[all420]

I have a DigiDoc 5 on my new rig and I would like to place the temp probes in various locations. First I would like one one my CPU to measure the core temp. How should I do this? I was going to tape it onto the chip but I think that it would break the contact between the waterblock and the chip. I also was going to drill a small hole into my waterblock, but is that what I should do, and if so how would I do that? Also, where should I put a probe to measure the temp of my HDD's? Is the top a good place, or does it not accuratly represent the true temp? Lastly, are the DigiDoc's probes waterproof? If not will adding some thin plastic (like Saran wrap) around them to make them waterproof affect the temp readings? I thought it would be cool to put on in my watercooling system to measure the water temps. One last thing, on my old rig (800 mhz p3) my chipset is reading ~107 F. It doesn't have even passive cooling. Isn't this temp a little too hot? Should I put on a chipset cooler? Thanks in advance

I'm at work right now, but when I get home, I'll post a picture or two here showing how to mount the thermistor so that it does not interfere with the HSF baseplate mating to the CPU core.

this is what i do with my compunurse thermal probe, i dunno if the digidoc ones are similar..

Thanks for the pic !

I've been trying to describe the temp probe placement to a buddy of mine for a week (no, you don't put it on top of the core...that's bad!):mad:

This pic should even make him understand...

I have a DigiDoc 5 on the way and I'd like to put it to work as productively as possible.

It will be in a Koolance case with a KR7A-R, 1900+, Kingmax DDR333 and GF3 Ti 500 system. CPU, GPU, NB and HD's will have blocks and the mem will have active cooling. The case will have 6 80mm fans total, three on the cooler, 2 on the 500 watt PS and one on the case back (and dinkers on the digidoc and DDR).

The mobo has its sensors, the Koolance has its and the Doc will have 8.

Everything not already is my posession is ordered so this thing will happen, it's not just a theoretical vapo-dream post.

Where can I get the best usage out of the sensors?

The CPU will have two on it already, I was thinking of putting one of the DD5's on it as well. I figure the GPU, NB and ram are other no-brainers. I was thinking of using a couple more to monitor the coolant temps immediately after the CPU block and after the heat exchanger to monitor the efficiency of the heat transfer. I figured I'd use the last two for in case air temps mounted on flexible wands so I can reposition them at will.

Does this sound like a plan or am I missing something obvious which I should monitor aside from PS or HD's?

I know going the Koolance route is a tad ghey for wc, but I look at it as a starting point for a more aggressive future heat exchanger deal when the need arises. I worked in industrial instrumentation and piping supply for years and have always been a street-rodder so I am no stranger to plumbing, heat exchangers and flow, but this is my first foray into electronics wc.

Once it's up I'll post photo documentation, but any signifigant case mods most likely come after I've beat on it some, I'm more of a form follows function type, make it work and then pretty up its face after. I already have plans to tower it ): wish the Koolance tower was out NOW :( and I may end up rebuilding the WC with a greater minimum diameter system (yeah I know, total rebuild), but I'd like to save any time possible by doing things as well as can be done with the available hardware.

Ideas? Opinions?

As always, TIA

Here was my previous way of doing it.

Take electrical tape tape it so the probe will come out the right way so either put it facing from bottom to up or up to bottom.

Now put some ASII on the probe and then put the tip slighty touching the core and your heatsink should bring the sensor down so it touches it as well as the heatsink.

[Hoot]

I'm home now and as promised here are three pictures showing how I did it.

In the first picture I trimmed the tip of the sensor so that the thermistor is barely exposed.

[Hoot]

in the second step you trim back a little of the heatshrink on the leads where the sensor is attached to the zip cord. This insures that the probe is not so thick as to keep the HSF base from firmly contacting the CPU core.

[Hoot]

Lastly, nudge the sensor tip right up against the core edge and glue it there with a tiny dot of AS epoxy. Tape the remainder down against the ceramic substrate with a quality tape like Capton. If necessary shave off any AS epoxy protruding above the flat of the core. Now, you're all set.

Good Luck

thanks hoot. Now does anyone know about where to place it on a HDD, waterproofing the probes, or if I should add cooling to my chipset?

Thanks Hoot.....that was very helpful!!

Why couldn`t I have found this forum 4 weeks ago:o . The information HOOT supplied would have saved me from making a disasterous error and not least the cost of a re-placement CPU.Especialy the point of the insulation on the edge of the mica part of the CPU , well i learned the hard way . Would anyone know where i can get hold of that CAPTON TAPE ive done a search but have not had any luck in locating any sources. Thanks.
