MSI BXMaster Thermistor Help

[comseeker]

I received my MSI BXMaster mobo a few days ago and I have read over the manual carefully and examined the board to get familiar with all of the jumpers, headers, etc. I came across a thin, tan, wire-like item sticking about 1.5 cm above the mobo next to the CPU slot. The manual calls it a "CPU Temperature Sensor: JSOR1" (follow this link to see a picture: www.lithomedia.net/cputemp.jpg). I believe this sensor is a thermistor, although the manual doesn't use this term.

My concern is that I place this temperature sensor properly when I install the CPU. Is this termistor supposed to slide up through the middle of CPU card so that it is positioned between the CPU ad heatsink? It's so tall that it doesn't look like I have a choice; I'd have to bend it out of the way if it weren't supposed to slide up the middle of the CPU card.

Thanks for your help.

Yes that is the Thermistor for the CPU. It just rest/touches the heatsink or CPU. It is not very reliable as you can imagine. There is no way to guide this tiny probe in between the heat sink and the CPU.

What I did was use the 2nd thermistor (you should have gotten another one with a pair of wires attached, and a metal clip at one end) ... and I removed the metal clip from it. I then carefully taped (use electrical tape .... cut to fit) this probe (has approx. 4" of wire attached that connects to the motherboard) between my CPU/chip and the heatsink "sandwiched" it inbetween the two. YOU MUST NOT PLACE IT DIRECTLY ON THE CPU/CHIP.... but rather as close to the very edge as possible. This 2nd probe is supposed to be used for the video card or the BX chipset. But you can use it on the CPU to get a more accurate temp reading. This works VERY well. Just make sure to not let anything keep the CPU/CHIP from making full and complete contact with the heatsink. If you take your time you can accomplish this.

I found this idea from an overclockers website. Unfortunately I no longer have the link.
Sorry. By the way..... there was a 9 degree difference in temp reading after I did this!!!! The CPU was hotter than the regular probe was showing... no surprise.

The MSI 6163 Pro motherboard did not have very good CPU monitoring, nor a built in sensor like many newer boards have. I thought the "master" had fixed this problem though..?

Just wedge it somewhere near the CPU. It only gives a rough guide as to the CPU temperature anyway.

You could use the TopTechIII sensor as mentioned previously after hackit it about a bit, but I use my TT3 to monitor the temp of my video card instead.

Yeah.... its nice to have the use of it for the video card. I just wanted a more accurate reading of my CPU temp.... so that was all I could figure out. Still I thought the "master" series... addressed this... and made the mb internally monitor the CPU temp. Guess not.
