Possible to manually adjust Antminer R4 fan speed?

[heathkun]

My R4 always runs warm even though it's in a room cooled to less than 65F.  I don't want to adjust the frequency the chips are running at but I would love to max out the fan since it's always running 80C+ but the fan is still not running at max speed.  I know we can ssh into the miner so why can't we adjust from command line?

I'd say it's not a problem.  My temps read between 57 to 98 on the various chip measurements you get in the GUI, and that's a B2 that's been running for almost a month now solid.

Mine on!

It has been running solid for sure.  However, heat kills and I'd like my investment to last as long as possible.  Thanks for the reply and confirmation that I'm probably just fine.
