He had intake and exhaust fans, but they were unbalanced. His intake fan was pulling less air in than his exhaust fan was pushing out.
LOL! That's not really possible. Worse case, one fan is working too hard and will have a shorter lifespan. However, air in will match air out or you form a vacuum <or preasurize the box> of some kind. Its not really likely with a cpu case.
This caused some dead air spots in the case.
Those are going to happen no matter how well you have the fans "balanced" <snicker>. Any situation with vertical and horrizontal planes will have dead spots provided there is only one intake and one vent. The only way to avoid it would be to have the front and back totally open with a fan blowing air across it... maybe one from the top too.
In all honesty, this should never be a consideration for why a motherboard blew up.
FYI: Fans are better at pushing air than pulling air, much like a propeller on an airplane.
That depends on the semetry of the blade. All fixed fans both pull and push air. And I thought the main reason propellers were more efficient up front was because they are operating with cleaner airflow.
This justification for why computer components are getting so hot that they melt the solder is getting rediculous. If a resistor gets that hot, there was most likely a problem with the solder weld in the first place. Simply re-soldering it most likely solved the problem. I've seen too many resistors cause a nice brown scorch on the motherboard and leave the solder fully in tact to think that was the problem.
Plane and simple: You do not need HVAC certification to put a computer together. Find a decent fan, use heat transfer goo between it and the CPU and you should be good to go. Of course, more ventilation is good, BUT IT SHOULD NOT BE NECESSARY. It amazes me that this has become acceptable or even the norm.
