Hi @all,
as probably some of you have exchanged fans - what kind of model / type would you guys recommend? How many RPM fans are you using to get the D3 quiet?
Mine are currently running at 2500-3000rpm with original fans. Any recommendations?
And thanks Blissz, for starting this and still working on an even better custom FW. :-)
I run it with the 120mm 2000rpm Scythe Slip Stream fans, but that only works if you run it at the lowest voltage setting. A relative silent 2500 to 3000rpm would be better. Anybody got suggestions?
Yes, I think I found one:
http://noctua.at/en/products/product-line-industrial/nf-f12-industrialppc-3000-pwmThis one looks quite promising actually. I just ordered some (they are not cheap!) and I'll give them a try over the weekend...
So...
New fans (noctua industrial line 3000rpm) installed on front and back side. Here are the results...
First of all I thought something is not working as I was only hearing the PSU. Then I remembered that my fans were previously set to 25% manual mode. With this setting the noctua fans are almost not noticeable. When running fans at 100% (3000rpm) they are comparable to the original bitmain fans running around 20%.
My one D3 runs now with the following settings:
Noctua fans front and back side, AUTO Performance Setting
Hashing at 16.5GH/s, fans running at 2300rpm (inlet) and 2400rpm (outlet) with custom voltage and MHZ set for each chain. Running for more than one hour now, keeping temp around 80°C each chain, while running at 18°C environment temp... So, regarding the noise - it's not completely silent of course but there is huge difference to the original fans.
But besides the fact that the noctua fans are quite pricy there are limits of course, they can't go higher than 3000rpm so high performance (>18GH/s) hashing seems unrealistic with those but if you want to get a more silent miner, the noctua fans are a good option. And no, I'm not getting payed to write that here. :-)
