I've got a couple of Bitaxe units running at home, and honestly, the way they're handling heat versus efficiency seems pretty decent. Just wondering if anyone else who's running small ASIC setups is experiencing a similar kind of stability during the hotter months. I'm totally open to sharing my logs if that could help anyone out.
If you replace the stock cooling system on these devices and replace the thermal paste with Arctic MX-4 or MX-6, you won't have any major issues. Summers vary widely, and I don't think yours will operate at 40°C.
It would be better to share the results when you find a block or write how long you have been mining Bitcoin in solo mode.
Stock, these will overheat in the summer (ask me how I know ). At the very least you'll want to replace the thermal paste as already mentioned. However, to be honest your probably going to go down the route of custom cooling solutions if you end up catching the bug. These open source mines are great for modding, and usually it results in spending too much money on them considering the astronomical odds of hitting a block. For example, I've got 3D printed custom stands, cooling fixtures.
Once you've got your cooling down though, they'll survive the summer and keep a decent efficiency in terms of consumption. I tend to under clock a lot of my hardware just for longevity though, which usually means you can get better efficiency also.
Really i m thinking on decrease the hashrate to 800 or 850 GH/s to keep a smooth temperature !
NB: During previous hotest period this summer i never reached 70 ° C always 60 ° 65° .......normally it s 41 °
If you have extremely hot summer temperatures for several months in a row, I would lower the chip frequency. But if you only have extremely hot temperatures for a few weeks, 35 degrees Celsius or higher, and the chip temperature is normal, I wouldn't do anything.
Your hashrate is already low, and you want to lower it unnecessarily.
Yeah i think i m going to keep my configs ... As people say run it until it brakes and buy a new one at least this period when we can hit the jackpot before any fork or some major changement....... it s a lottery to be honest !
Thanks for the advice...
I don't like overheating chips unnecessarily. If your temperature doesn't rise above normal, leave it as is. If you're not too lazy, change the thermal paste before summer; it will lower the temperature by a few more degrees.
I don't want you to overheat the chip following my advice.
