Questions about the Abit BM6...

[Nutcase99]

First off do you know exactly where the sensors on the motherboard are? I know one is under the cpu (it doesnt touch does it make it less accurate?) Second can the motherboards fan connectors support a Delta Black Label fan (60x60x25 38CFM 7000RPM) without frying the connector on the motherboard? I have heard that this fan can do that if the motherboard doesn't put out enough power and I wasn't sure if the BM6 did or didn't.

The other active sensor is lower left side of the BX chipset heatsink. I wouldn't want to run that type of fan off the mainboard traces if I were you. Go directly to the power supply for that one. I realize though that you are after fan speed monitoring.:frown:

Well I ordered the 3-4 pin adaptor but is there anyway to moniter the fan speeds?



<< The other active sensor is lower left side of the BX chipset heatsink >>



Umm does that mean that it wouldn't be as accurate as some of the other motherboards? And what about the sensor under the cpu it doesn't actually touch the processor so does that make it less accurate?

This is all comming from seat of the pants experience, but here goes. The RT1 thermister measures the temp of the mainboard (it's the one near the BX chipset) and I would think that the temp its reporting is very accurate. The RT3 is to measure the CPU, and yes, since it does not actually touch the CPU it would not tend to be as accurate as a probe touching the CPU, but as to it's accuracy compared to other mainboards? Good question. I would think the core temp would be quite a bit hotter than what is reported as RT3 would have to be measuring ambient air temperature within the socket. And of course a flip chip CPU such as the CII has the core located opposite RT3, so how accurate could that really be? I Know that my current CPU operates at a higher temp than did the 366@578 (PPGA) I had before this one. That was with a stock intel fan which was sold with the 366@578, and before I got my Gorb, so I had time to use the intel fan on the two CPU's.
As to your question on fan RPM? Maybe a jumper to the RPM reporting post on the mainboard connector from the rpm sensor wire of the fan(?), not sure on that one.
You could download a manual from the abit site if you don't already own one.
