How do you accurately monitor the temperture\voltage values that are provided by motherboard smart sensors? Ive read that that dtemp\speedfan\hardware monitor use frequency as a means of predicting temperture therefore are inaccurate! Is this true? Anymore more information\sites on Smart motherboards would be also greatly appreciated. Thanks in advance, Meniscus
Temperature monitors do not predict temperatures, they give you the temperature based on the readings from the sensor beneath the CPU socket/other sensor areas.
Depends on the temp sensor that's being monitored. The temp sensors on a motherboard are a certain distance from a heat source and they are calibrated based on that distance. Of course, this can be largely influenced by the ambient temp, so yes, this is not the most accurate. However, motherboards can also read the on-die temps if the CPU has a built in temp sensor. I believe that all current CPU's have them. How accurate they are, I don't know. You can buy a temp sensor that has a probe and stick it close to the CPU's die. If it has a heatspreader like the current crop of CPU's do, you simply attach it to the side of the heatspreader with a thermally conductive epoxy, like Arctic Silver Epoxy. You don't want to pop off the heatspreader as Intel and AMD have them pretty firmly glued on, and that has the tendancy to take part of the CPU die with it. There's nothing like having an $500 CPU go down the toilet because of this, as I've heard many horror stories. I've fried a few CPU's in my time, but nothing that expensive.
Is there any way I can log the temperture from these sensors without the use of those monitor packages? Would it be a difficult task to write my own software? They re free arent they! Do ye know if the source code is available anywhere?
Not sure not on that, I'll have a look around for any open source libraries that might be available for windows to code a small logger like that.
have you any sites off the top of ur head on these "open source libraries" just to put me in the right direction? Sorry its just im quite ignorant when it comes to software!!
http://sourceforge.net/index.php There is a lot of Linux stuff due to the nature of the beast being open source, but that's the one site I have off the top of my head.
