No issue unless you got a faulty device.
Although I hate them noise, too noise for a home if you have more than one.
The amount of power they draw is very high too and as a solar energy miner I am trying to avoid Asic miners as possible.
I hope that in the near future we will see a lot of home miners that have higher TH power, maybe over 100TH and also more efficient to run.
If you are new to the miners you can face small issues like inconsistency and instability but trust me that's because you are new to mining, normally you need to place the miner in a well ventilated area for better cooling or you will face these issues.
Make sure the fan spins and also make sure the psu isn't overheating.
It seems so. Noise and heat dissipation problems should be the most troublesome. Then why don’t you install a blower muffler? It can solve the noise problem and dissipate heat effectively at the same time. You can go and find out.
nope.
it is more likely down clock a bit. they will not over heat as much and are quieter.
the pot fan setups do help but most of the gear runs way too hard. which makes it to hot and too loud.
Also the pot fan means you need to bypass oem fans.
So if the pot fans break there is a huge chance you over heat the gear.
If you go the pot fan route you should use an epic controller and set the overheat numbers very low 78 vs 85c
if the pot fans break the gear may be saved due to the lower heat setting.
here is a 1 board t21 so 1/3 the power and hash means it does about 55th
but I super under clocked it to 18 th .
no overheating no noise and it will last for years run this way

But isn't the purpose of buying a mining rig to mine? Once mining begins, the rig will run at high speeds for extended periods. Won't this lead to heat dissipation issues? Some mining rigs, especially those with air cooling, are particularly noisy, so purchasing the right accessories is crucial. It's unlikely that a mining rig itself can resolve the issues of high temperatures and noise from prolonged operation; accessories are essential.
