I just tried a 3 pin fan on the second board on the miner.when you attach it to 3 pins from the top going g down the fan works at normal speed. When you connect it starting with the second pin from the top the new fan doesn't work but the stock fan ramps up in speed a lot in the ui it's at 3020 at the temps are down to mid 3os. Is it Ok to keep it like that? It would be great for overclocked miners.
It has same effect and as much use as you just driving your car in first gear so you can see the RPM counter near the red. It would be a great way to help burn out you fan faster.
Ant's are happy at 50c and below, the fan is set to work hardest at 60c and the unit shuts down at 70c.
ok i see i felt as much , otherwise everyone would have done it. shut off at 70 thats high compared to some other machine avalons were at 60 i think.also could 400mhz over clock burn the board out?
No 400Mhz will not burn out the board unless the components are out of spec but greater than that starts to push the VRM's and that could cause one to occur.
I run ant's at 400Mhz @ 50c in 23c ambient @2200-2500 rpm on a single fan. As spring turns to summer I will drop to 375Mhz or add cheap 130CFM fans, by the summer and assuming that the difficulty has not increased to make them unprofitable I will drop to 350MHz or below and add cheap 130CFM fans.
i see, sounds reasonable enought. And the cooling obviously is a great help for the overclocking process. it must get quite hot where you then. u.k is mostly cold even summer isnt too bad for minng.
I am UK, in winter I use the miners to heat the house instead of oil hence the 23c ambient, I prefer 20c but my wife prefers it hotter at 23c so I agreed to compromise at 23c
In the spring I will move them to the garage that has more than enough holes in it to let a draft through.
