PC Stats has posted a review on the Intel D850GB P4 motherboard
Thermally speaking the D850GB comes equipped with some very interesting fan controls. I can just imagine the Intel motherboard designers huddling over the drawing board, cappuccinos in hand, having a heated discussion about how many fan headers to include... Perhaps one of the younger engineers with an eye towards cost cutting was arguing for only three fan headers. Another engineer, who if you think along the lines of the godfather for a moment, leans back in their chair and says in their most mob-boss like tone; No! I giva youa four fan headers!Read more
What ever the story really was, the fact remains that the D850GB comes with four fan headers, two of which are thermally controlled by the BIOS. The two thermally controlled fan headers (Fan1, Fan2) can adjust fan speed depending on the input received by the system boards thermal sensors. If RPM sensor enabled fans (the third wire on the fan lead) are used the tachometer signal will be sent to the ADM1031 controller which will scale back, or increase the speed of the fans to compensate for the thermal condition.
