Ducting
Posted: Fri May 27, 2005 3:35 am
I have read many articles on ducting and i am convinced that ducting has alot to offer cooling.
Here is my proposed idea/ theory.
Right now there are 2 components which wither come with or require a fan to cool it.
1) CPU
2) GPU
3) Northbridge
From the list above the GPU has a sort of ducting heatsink already available and that is the arctic cooling nv silencer.
The northbridge only needs a fan because the cheapo manufactures can only afford to put some rusted piece metal they got from the local scrap yard on it as a heatsink. You can use a zalman and some careful planning with case fans not even need a fan.
Then we come to a CPU. The traditional setup is that a fan is placed over the heatsink and then blows air down onto the heatsink (PUSH).
This would then cause the air to brush past the hot fins of the heatsink hence transfering energy (in the form of heat). This would then leave air to go in mixed direction around the case.
Here's my plan, to build a duct which will be attached to the rear exhaust and hover just over the heatsink fan. The fan will pull instead of push and blow the fan into the duct and hence out of the case.
Has anyone tried this and got good consistant results? or is this a first?
I know some have tried ducting air from outside the case onto the cpu heatsink. But my thinking was if you could lower the case temp then you could achieve a similar result and also benefit all other components in the system.
