pH - you seem to be on webmedics case a lot lately (mostly in regards to his plans for a WB roundup) in regards to accuracy and resolution, and the fact that he needs better temp monitoring equipment. And now you post up a graph for us all of your CPU temp jumping around all over but within a range of about 1.4C and you mention that you have .125C resolution but fail to mention that your sensor is only +/- 3C accurate (stats on chip taken from page 2 of Maxim's pdf on it at http://pdfserv.maxim-ic.com/arpdf/MAX6655-MAX6656.pdf )

Now maybe this should be in that other thread - but I'm putting it here in response to your graph. You now are the one making conclusions that is pushing the limits of your measurement equipment, and yet you continue to tell webmedic not to do the same thing.

Webmedic - go ahead and do your roundup with what equipment you can afford - don't bankrupt yourself on it trying to please just a couple people. Everyone needs to realize that just because a sensor is accurate to +/- 3C does NOT mean that it will always be off by 3C - with a few test runs it should average to be very close to accurate. I for one at least really look forward to reading your article.
