Just received the miner. It is freaking loud at my apartment. I am pretty sure someone is going to complain. I tried setting the fan speed to 70% but chip temperature is going beyond 90 C. What is the ideal fan speed and temperature guys? PCB is around 70 and chip around 100.. Is that too much?
PCB can never go to 80 or it will break...
Try to keep it at 60-70 for best results.
I recommend opening your window and pointing the outtake fan towards it. Also, You can only lower the fan if you are going to lower the frequency as well otherwise it will overheat.
I recommend getting earplugs to sleep because it will be hard but would be best for right now. Either that or call a friend and ask them to run it in a spare room for the next 1 week while you buy fan shrouds, cooler, and insulated flexible duct to make a box to silent it a little.
Window is open and people walking outside can hear it very well. It is like a vacuum cleaner running lol
Right now, the fans are at 5800 RPM (auto mode), PCB is 65-70, chip temp is 90-92. Getting 830 GHS
I tried setting fan speed to 70%. That significantly reduced the noise but chip temp were at 100 within few mins. I switched back the fan speed to auto. If I let it say at 70%, chip temp would hit 110 I guess. lol.
Now, what is the max chip temp that is "ok" for device to at least last 6-7 month?
If I want to lower the noise, I guess I have to underclock. Is "frequency" the settings to underclock? Can you tell me what range I should try changing and play with so I can lower the noise (and also hopefully keep the temperature ideal)?
Sorry about too many questions. This is my first ASIC. Have been running GPU rigs always...
I underclocked mine to 550 and they're still running at 75C with 30F air on the input side.
I do not have a portable AC to point to the miner. Silly question - when you say input side, it is the side that has the ethernet port, right? Also, which side should face the window?
The side that blows air out like crazy right? And the ethernet port side should face inside the room? Correct?I lowered the freq to 550, PCB is at 65-70, chip temp at 85-90. Outside temperate is 30 F and the big window in the room is open but its still running so freaking hot.
Will this fan do any help for my situation? I do have that lol - https://www.staples.com/product_2143666
As others already found out as well: The A3 and D3 are very similar. I even found out that the software inside the controller chips on the hashing boards is exactly the same.
