Inspiron 5680, adding a front fan?
Inspecting my new 5680 (the version with the DVD drive), I see a space in the front panel that I think is intended for a fan. I’m going to be filling the drive bays by adding a Samsung 860 EVO (SSD) as a boot drive and an older 1.5TB hard drive for backups, and I’m concerned about heat.
Anyone have any info on adding a fan, if necessary, such as size, issues I may encounter controlling it, etc.?

As suggested, the spot on the front of the 5680 case is designed to accept a 92mm fan. I bought a Noctua NF-A9 PWM. Successfully installing it wasn’t as simple as I’d hoped (it had to be installed entirely from inside the case), but I managed:

Looks like 92 mm would work. Try the following link.

If you install standard fan and it complains then the fans use non standard wiring.
Otherwise its standard.

Dell May not use standard wiring or Pinouts on their fan headers.
This can lead to self-destruction for a dell fan on standard motherboard or the other way round.
For 3 wire they reverse 12v and tach.

The Noctua fan comes with rubber pegs/posts to install it. I assume that most fans come with some sort of mounting pegs, given that preassembled computers (like our Dells) don’t generally include them.

Correction, same issue with low RPM front fan, Noctua, about 800-ish rpm's. But I'm running a 5675 (very similar).
