Hello everyone... Midsummer is coming closer and thats why I took a closer look on the temps in my pc. At this point I wondered why most mainboards are displaying the 'useless' MB temp, especially when I first saw extra connectors on newer gaming mainboards, allowing to connect a wired temperature probe and hang it up where you think it is important. So the time has come for a few experiments with my Asus M4A88TD-v Evo/USB3 Board. I figured out that the controller that is used for Fans, Temps etc is called IT8712F. Datasheet is available too, but is only telling me that thermistors or thermal diodes can be used as probes at the TempIn Pins. Speedfan is more cooperative and says that the chip is configured for thermistors on all three temp inputs. With this information I began the search for the sensor component of the MB temp. And found that little SMD PTC Fuse (P150-24) that you can see in the attached Picture. The diode next to it was also able to detect the cool temperature spot I tested with, but not as quick as the fuse. They stick together on one great solder pad with one leg each, so i suppose that the coolness was conducted from the diode over the solderpad to the fuse and was therefore displayed slowlier. Long story short, my question is: Is it worth a try to desolder the ptc fuse, solder it onto a thick wire and connect the wire to the origin pads ? Has anybody experience with ptc fuses as sensor components or is it me thinking wrong and the diode is used in combination with the ptc fuse ? I am not familiar with thermistors so i will be thankful for every comment!
