Fanless Power Supply Mounting

post #1 of 4
Thread Starter 
Does anyone know how you are supposed to design cases to accommodate them? Manufacturers like Seasonic tell you they dissipate heat upwards, so if they are mounted right beneath the motherboard then wouldn't the heat be directly dissipated onto your components?

That is exactly what will happen.
I'm guessing you are going for a low powered build if you are using a fanless power supply? Probably won't be generating too much heat.

You could get a couple of silent fans, or normal ones and run them at minimum RPM (40% or thereabouts) and have some airflow through the case without any noticeable sound. (I have 13 fans in my PC, and when they are all running at 40% you can't hear the system running unless it's midnight and there is literally no other noises)

Unless you have very good airflow in your case a fanless PSU is really not a good option because as you said the heat goes stright up
There is a reason most PSU´s have a fan in them.

The system power consumption would be at around 100w.

Are there cases with layouts that could dodge this problem? Like having the PSU not sitting directly underneath the motherboard?
