Title: Innosilicon a4+ and fans for it Post by: Tarl2020 on December 13, 2020, 03:06:41 PM Hi all,
I've the issue - bought new fans for a4+ and the problem is - When I powering it on, fan working on 100%, then software shows it 40%, fan working 60, 50% working 50, 60% fan really reduced to 40. Seems that management is working wrong, how can I solve this? Title: Re: Innosilicon a4+ and fans for it Post by: Ken_terrance on December 14, 2020, 03:30:54 PM What type of fan you buy? What's the fan voltage if the old fan? How many wires are on the fan? How do you solder the fan? All this questions are very important, to have a total control of fan speed I'm guessing the fan should have up to three or four wires in different colors, drop more info mate

They are generally not having custom made fans but instead using an available unit to keep costs down.

Cooling down a asic miner isn't a joke, if you get anyhow fan the heat will be much, it's better if OP get a high quality fan for the asic miner, fan isn't fan, grades matter here or else your asic miner will over heat every hour and reboots over and over, you don't want to mess with asic cooling Title: Re: Innosilicon a4+ and fans for it Post by: miner29 on December 14, 2020, 05:51:20 PM You can usually pull the existing fan and read the label...then search Amazom/Alibaba/ Etc for a match or same spec fan.

No...maybe reread what i said. Yes i own some asics....bitmain BTC / ZEC / Sia asics. That is why i said look at the fan label. It gives the spec of the fan. Look that up and get the same or a same spec fans. There is no rocket science its fans. It is a measure of RPM / CFM / static pressure / V/W. I didnt say just get a fan....maybe you should work on reading comprehension. |
