Are temp probes waterproof?

[fourty03]

Hello all,

I am wondering if the temp probes that usually come with fan controllers are waterproof or can be waterproofed in some way.

My cpu is watercooled, and would like to monitor the water temp (if possible).

Also, I have two Sapphire 6950s xfire, and would like to know the best location to place the probes. I currently have them near the video output headers, through an opening near the crossfire and bios switch. I noticed the temp readings via the probes are 25 ~ or so degrees off versus what it reports via software.

I currently have two fan controllers -

A Scythe:

and an Aerocool "X"

The temp probes look very similar (the clear tubes on them come off prior to installation to the location that will be temp. monitored.)

Thanks all



*EDIT*

Also, forgot to ask, since I have both fan controllers, I have so many areas that I can monitor...

The Aerocool has 5 probes, and the Scythe has 4. I currently have the Aerocool probes at:
*CPU
*Northbridge
*1st GPU
*2nd GPU
*PSU

and the Scythe:
*Behind CPU near balckplate
*outside watercooling resovoir
* Raditor
*SSD cages


Is there a better way to utilize the amount of probes (and placement) and also get an accurate reading of all the temps

They look like this:

u need 2 barbs for them... or a coupler to attach it to something like a rad or in my case this bay res:

and i use a lamptron FC5 controller to connect those probes up and pull the DDC RPM sense line.. so i can tell if a DDC has failed right away.

First temp is air inside rad chamber.
Second temp is cpu water coolant temp
third temp is GPU water coolant temp
fourth temp is Board water coolant temp.

Basically the last 3 tell me the coolant temp inside each of my loops.

I would be concerned with using those in water. Surprised companies are still selling that old tech for measuring cpu temps, I guess its because those probes cost about 5 cents and a digital probe cost about $2. All these are is thermistors. Their resistance changes as the temperature changes. Shorting them out will not harm the device reading them but will make the reading wrong. You just need to put something on them that will keep out the water but still conduct heat. I use a real thin layer of silicone sealant for my digital sensors.

there is no reliabile digital temp probe reader unless u jump over to crystalfont or matrix oribitals.

Most of the fan controllers that display temps are analog temps.... not digital.

i understand your point tho, as i have been using digital dallas type probes when i did testing for companies.

But in all reality unless ur aiming to please a group of wide audience... analog is fine for personal use.
