I have the Intel DP67BGB3 motherboard. It replaced a dp67bg due to a recall on the sata ports. I reused the hard drive from the board with the problem and installed it on the new MB.
The new DP67BGB3 MB rebooted without any issues. I am currently using the MB. I noticed that when the CPU temp increases, the fan does not automatically spin faster. The CPU temp is at about 35c idle and about 40c when in use and about 60c when stress testing. The fans rpm increases from 659 rpm to about 680 rpm. No higher. The room is about 80F. The BIOS shows the same 659 rpm. I have the CM212 plus heat sink using AS5.
The recalled MB dp67bg always idled at about 30c and the fan increased and lowered its rpm as needed.
Is this a a BIOS configuration issue? A heat sink issue? Or some other issue?
Its all BIOS. There is an extensive fan control section where you can set the minimum speed % as well as the max speed %.
You can also adjust the threshould temp to increase the fan speed. Its probably set to deafualt at 78c or somthing, and since your only hitting ~60 its not increasing the speed. If you lower it to say 59 then it will ramp up to the desired speed whenever it gets hotter than 59.
BTW 60s is fine for full load with these CPUs.
