Should I add an air duct to this case?

post #1 of 6
Thread Starter 
First post. smile.gif

Alright. I'm building a microATX-sized system for my parents, and it's pretty much done. However I have a spare "air duct" that I'm thinking of installing.

Please take a look at the picture below. Original pic was taken from Newegg, but I have the same case. The system has two 120mm fans: 1 intake and 1 exhaust (plus the PSU fan obviously). There are NO side fans, and I don't have any spare ones at the moment.

My question is: would adding an air duct (where that blue question mark is) disrupt air flow? Should I leave the spot empty?

This is what the air duct looks like:

Thanks.

I think your better off leaving the ducking off. I find they make little to no difference and instead just make a giant anomaly in the ariflow

Unless you can make it line up perfectly with a graphics card intake or something and you are specifically looking to lower those temps probably not.

The Air Duct is a feature of a Thermally Advantaged Chassis. Back in the days of Pentium 4, Intel released Chassis Air Guide Design to help out CPU cooling. See pic 1.

It is very useful when the CPU cooler is a downward blowing type (eg stock ones). And if your cooler is such, it will not disrupt cooling to the CPU area but will benefit. And as it can extend/retract, make sure its spacing is 12-20mm away from the CPU cooler as shown in the pic 2 below.

And, welcome to OCN!

If your computer is right beside you, it's louder but cools your cpu slightly better.
