140737	2003-05-02 02:39:00	Is there any way I can get my motherboard temperature sensors calibrated? Currently, they're out by 6 degrees Celsius and I would like them to be more accurate (the PC's not in a airconditioned room, and the ambient temperature of the room rises quickly so I would like to know what the right temperature is). Is there any way I can do it myself, or do I have to take into a repair shop to get it done? The motherboard's a Gigabyte GA7VAX1394. Has anyone else had a problem wiht themperature sensors on this motherboard, or is it just mine? Wintertide	wintertide (1306)

They have a nominal value at, say, 20 deg C an vary by a certain percentage for each degree of temperature difference. They are not precision instruments. :D They give an indication. I suppose it would be possible to cut one of the leads, and put a trim pot in series (if the error is in the right direction). I think you're better to just "know" it's wrong and by how much.

140741	2003-05-02 06:12:00	I have the same board. There is another sensor on it that may give a more accurate cpu temp. Its called LM90-local in MBM, linux calls it max1617/temp1. It seems to usually sit 6 - 8 degrees above the offical cpu temp (currently 30 vs 37 degrees while running my NN code). And it responds to changes in cpu usage faster. Of course it might just be coincidence.	bmason (508)
