Thanks. So you have the two FD fans in the front and the Noctua in the back as exhaust. That's what I was planning. Remove the top drive cage for better airflow, then one SSD and one HDD in the bottom cage with a slow fan in front of them.
But I'm still debating getting three Scythe 1300 RPM PWM fans, for what I've been convinced is better fan control (in one of my other fan threads).
Happy to share experiences!
With 1 HDD that sounds fine. Due to the poor airflow of the FD design, I had to split my 2 HDDs up, otherwise they reached mid-40s (Celsius).
I've had Scythes, S-Flex, Kama and Slip Stream in various flavours, liked them all. Definitely better sounding than FD, very smooth
was my overall impression. If you're not after absolute silence and pristine soundscape, I would try with the stock fans first though, since Scythes can be expensive. Diminishing returns and all that.
