mmfish Posted December 13, 2018 Share Posted December 13, 2018 Anyone have experience with mounting a fan over the MB behind CPU? To cool the CPU backing? It would seem to help, thoughts? Link to comment Share on other sites More sharing options...

mmfish Posted December 14, 2018 Author Share Posted December 14, 2018 Backside of MB is open on most cases, heat is generated/radiated by CPU in all directions. All cooling systems attached to the cpu top. Exposed underside of MB must get warm and a fan over the Rear MB should disapate heat? Link to comment Share on other sites More sharing options...
c-attack Posted December 15, 2018 Share Posted December 15, 2018 Most likely this be of no consequence or not beneficial in any way. The CPU heat does not radiate in all directions and instead takes the easiest, most conductive path - through the metal plate on the cooler. That’s why it works. Heat transfer through the multiple fiberglass layers of the board is not typically an issue and reducing the surface temperature on the backside would have little benefit to the front side where most of the heat is generated. The individual modules on the front side of the board create heat when electricity passes through them, so fan action for direct cooling is far more effective on that side.
