Fan Configuration

post #1 of 4
Thread Starter 
I have a an HTPC in a Lian Li Q09FN with a Noctua L9a

I chose the noctua for its slim form and low noise. When I installed in I noticed it wasn't any quiter than that of the stock fan.

Then I noticed; The noctua fan is pulling cold air in to the heat sync, while the case fan that came with the Lian Li is an exhaust fan.

What should be the proper fan configuration in this situation?

Thanks

Change the orientation of the heatsink fan - check temps/noise, change the orientation (intake) of the case fan - check temps/noise. Compare them and use the better.

I think I had silverstone htpc case in hands that had case fan in similar position like said lian li, but it was intake - and it worked well. So it may work for you.

Also make sure it is installed properly and dont expect too much of it.

@CM Aztec
Essentially what I am saying is that the computer has only 1 case fan (exhaust) and 1 cpu fan (intakes air from case) So the two fans are not working together.

Is it possible to replace the Noctua fan with a quieter option? I have some room to spare so it could be a little thicker.

Thanks
