Do your fans also run at different RPMs?

To keep the temps the same as the other batch d3's (80 degrees average during the day, 70 at night Silent Auto), 17.2 GHS average, I have to run the latest batch d3 at "Default auto"

Fan speeds
Batch October/beginning November fans:
Daytime: xxxx /3980 RPM sound is concentrated on the inside of casing, less audible outside. With stock firmware fans run at xxxx/4500+ RPM.
Nighttime: 2160/3210 RPM

Batch end November fans:
Daytime: 4xxx /5800 RPM very loud, different sound than first model fans, like it's concentrated on the outside of the casing, sound is heard even at a distance.
Nighttime: 3090/4080 RPM

Good to hear your d3 is fine! Grin

You can replace the fans with some other models. I actually run mine now with two Scythe Slip Stream Slim 2000rpm, 120mm. This is of course not the solution if you want to run at high hashrates, but for the lowest voltage setting and 15 to 16 Mh/s this is a real nice and quiet fan.
I also modded the PSU: I added a small fan controller to have it run at half the RPM. Now this combination is actually really silent. I can have it run it in my living room if I want to.

Thanks for the advice blissz, will definitely look into those fans as well, anything to help being able to live with these things lol. I also bought some 6" inch and 12" Acoustic Ducting. Plan to strap the 6 inch ducts to the fans and put the whole machine into the 12 inch duct as well and wire all the ends to separate windows to the outside with mesh over the openings (got some nice bug splatter already).
