Hello,
I have recently purchased Innonsilicon A9 Zmasters, I was wondering if anyone could help me out. The machines are brand new and they seem to crash every 1-2 days, does anyone know what could be the cause of this, at first I thought it could be the pool that keeps going down so I switched to a different pool but the machines still seem to be crashing every 1-2 days. I did some research online and some people say it could be caused by the fan speed readjusting itself all the time.
Here is my miner log history:

If anyone could help me it would be appreciated!

how often do they readjust fanspeed?
You write A9 ZMaster's with meaning more then one!
If they all "crash" after about the same time then it's probably the memory that gets full and they REBOOT.
If they crash simultaniously then it's more probably a power issue.
If they do a REBOOT at the same time it might be a problem with internet connection (or connectionproblem with the miningpool you are using).
(What do the logs say?)
If they all chrash and it's not related to memory getting full and not bad cable connection it might have something to do with hight ambient temp and coolingproblem or even more likely problem with power fluctuation from the wall sockets to PSU's and/or from PSU's to the A9's.
If its memory getting full:
If you point one at prohashing.com and one at some other place like nanopool, flypool or whatever you will likely see that the one at prohashing doesn't fill upp its memory like the others.
If you compere how much the different miningpools fill up the logs there is your answer to whats happening.
Good luck!
