Blowing air directly on CPU or from the side?
Hello
In case the CPU on a fanless mobo like the Intel D510MO turns out to still need a fan to cool it, should I use a slow-running 12cm to blow fresh air directly on the heatsink or should it blow air from the side instead?
What about having two fans on the case: One intake to bring fresh air from the front, one outtake on the back, and have the air flow between the two and cool down the CPU in between?

Thank you.

I think that any fan at any reasonable speed will cool that CPU just fine. Having two fans is probably unnecessary.
I have a similar board, an Asus at3iont-i. I thought that I would have to be clever putting it together, but I just put a 120mm fan right on the cpu heatsink, pushing air up, at only 550 rpm, and the cpu never gets above 35c. The case it's in has a lot of vents though.
I see in another thread that you're building your own case for this. I would go ahead and try different things with one fan, but I wouldn't spend money on two fans. You probably won't need it, as long as the hot air can get out of the case.
Good luck.
