Interesting intake fan concept:

Ok, I've never seen this done, but it'd be badass if it has been.

Some cases have sliding mobotrays. Others don't. In a case that doesn't, one could cut the side of the case where the mobo is located. They could clear metal obstructing a fan placed there to blow directly on to the underside of the mobo.

Now, this wouldn't have a big effect on CPU cooling, or even case temps. However, if you modded a 120mm fan underneath where the chipsets are located (Nforce2's northbridge for example), I'd imagine you could get decent cooling. Same would apply to capacitors located on the mobo. Having channeled, fresh air underneath the mobo could have positive effects on mobo temps and longevity. If one didn't want a 120mm, you could case mod a few 60mm fans there.

Why don't people do this? I can see where powering the fan could be an issue, but one could get molex adaptors to give power.

thoughts?
 
I doubt it would have any effect. Motherboards are more insulator than conductor, so a majority of the heat of any of the components on the motherboard is going to be on the component side of the board. In other words, the amount of heat you would remove by blowing air across the trace side of a motherboard would be insignificant to the amount of heat removed by blowing air across the component side. Yes, the back side of a motherboard feels warm, but that is nothing compared to what is on the other side of it. Also, capacitors shouldn't need cooling. If they put off that much heat then there is something wrong with them.
 
i have a ic7-max 3 so the otes takes care of the mosfets

i just do it so it doesnt get as hot under my mobo sicne i have a lot of wire back there
