Just started a new build. Based on some advice from Dan in another thread, I want to install 2 case fans:
- a Noctua A9x14 under the mobo
- a Noctua NF-A9 under the PSU

Has anyone else done this before? I cannot seem to secure the fan correctly with the silicone mounts because of the shape of the holes where the hdd bracket originally was.

Does anyone got any suggestions or ideas.

Sorry for the newbie question: first build ever going on here ;-)

With longer m3 screws you can also keep the HDD tray and use it to secure the package all together and also cool the HDD that otherwise would be left all by themselves.

Here you can see how I did it ?

Hey sorry to post here so late but I just came across this and was able to get this set up installed in my case. Thanks so much, i've been trying to get a second case fan in and this worked perfectly
