You could try lowering >the fanN_div values to obtain nicer fan speed graphs (i.e. with smaller steps.) Hi Jean, thank you for the interest. A few comments on this particular topic, and then I've got a different topic for you. I'm not sure smaller steps makes for "nicer" graphs! :-) I'm most interested in having a graph that is instantly indicative of the health of the fan. Fans don't usually just die and stop running. Instead the bearings slowly go bad, and it starts with intermittent slowing down. Hence I do want good resolution at lower speeds... and large steps that make it obvious something is happening when it starts slowing down. However, to make apparently "smaller steps" on the graph it would probably be better to extend the graph range. I'm using a pretty small range, from 6000 to 8500, which tends to make the variations look huge. A graph range of say 0 to 10000 does make that a little less distracting. Plus there are relatively no real problems with using higher divisors, but there are definite problems from using lower ones, e.g., with slow speed fans. Hence while a particular individual might well use lower divisors with high speed fans, an example program probably should stick with the highest divisor, 8. I've just changed gnuplotscript.html first to a 0-9k range, and then to a 0-10k range. I kinda like that last one, so I'll probably upload that revision and a new set of images. Note also that previously today I uploaded a new set of example graphs and a new version of gnuplotscript.tmpl to generate them. A number of minor and a couple of major changes. The temperature plots are now banded with different colors depending on the temperatures being plotted. At first I had 5 colors, but then decided it wasn't better than just 3 and uploaded another set. Cool temps are blue, then it turns to magenta, and if it gets up close the "maximum" line, it turns to red. On to a second topic. If I remember right you are the one who took interest in the lm_sensors tickets on problems accessing the Hardware Monitor section of the W83627HF Super IO chip on some of the Tyan motherboards (that was a year or two past, and some of the ticket numbers are 729, 764, 808, 861, and 867 and 941 among others). There was some asm code (861) and C code (867) posted that, while somewhat buggy, will enable the W83627HF's hardware sensors. But nobody dug into it far enough to really answer all the questions, and the code presented isn't something that non-programmers would want to use. I just spent a bit of time experimenting to figure out as much as I could about what is going on, and wrote a more universal program to enable and initialize the W83627HF sensors. It works on the S2462 motherboard and would probably work on other Tyan boards. The program is on my web page at http://web.newsguy.com/floyd_davidson/sensors/ Have a good day, Floyd -- Floyd L.
