P182 + Scythe Ninja + CPU fan + ducting

Hi,

I'm planning on creating a duct for more cooling performance.

Is it useful to create a duct if you have a CPU fan clipped onto the cooler?

I have a P182 case, a scythe ninja and yateloons 12DSL.

Who has done a duct system and how have you done it?
Please post as many pics as you can for examples.

any advice + tips = welcome

thx

There are lots of examples in the General Gallery section.

My own system is fully documented on the Superquiet Superclocked article in the Do-It-Yourself section.

The short answer is that ducts help if you want to run your fans so slowly that they can't be heard (600-800 RPM).

Here's my previous ducted Ninja project. There are many ways to make ducts for a Ninja. This particular one uses a 92mm Nexus, and a tight wood duct. But the CPU is low-power, a Pentium M, so it doesn't require much airflow.

Tell me, what is important when creating a heatsink duct?

IMHO....make it light, easily removable, secure. And check temperatures of everything, before and after the duct is installed. If it isn't making any difference, no sense using one.

The main point of a CPU HSF duct is to direct the CPU's hot air straight out of the system so it doesn't contribute to the VRM or power supply or video card or motherboard (especially north bridge) heat/temperature.

As CPU wattage continues to drop (especially since Core 2 duo/quad), this has become less important. Now the main reason for a CPU HSF duct is to be able to run the CPU fan slower and thus more quietly.
