i have 3 s7 with 1 fan, my fan speed all set to max 100% = 5880 rpm, no choice the temp. here now is 35'C.
then tell us rpm please at 90%
if rpm does drop to 5500 at 90% check the temps very carefully.
basically fans at max rpm and fans at just under max rpm cool the same.
ie a fan running at 5500 rpm should do the same as a fan at 5880 rpm.
and that slight underclock makes fan last a lot longer.
It is a sweet spot all fans have it and it depends on the fan and the heat sink pattern.
If you can run the fan at 5500 rpm vs 5880 rpm and not overheat you will save some money.
Tested one of the S7 with 90% fan speed =5280rpm , the temp rise 2'c on each board, 72,72,76.
when the fan run at max, the temp read 70,70,73.
room temp = 35'c
so it appears that the 1 fan units 100% is the true number . that is bad that you need to run at max speed (kills fan very fast)
humor me try 95% see if the fan gets to 5500 rpm and temps are equal to the 5880 rpm as weird as request is if you find 5500 rpm keeps you low enough .
You are really hot whats the room temp 35C or higher?
I've got both the B12 and B16 at 750M @100% fan(s), w/good numbers still (1 hr out). May finally get >5TH/s from each...sorta kinda numbs the hurt from losing my mythical 80A. Will still have to monitor closely around 1500 local time as that is when ambient can get up to 80-85F this time of year, and despite having 1,250 CFM blasted through each of their insulated 7x17x45 (in.) styrofoam tunnels, they could heat up I guess.
I know...movie stuff. I could care less about MTV, but I want my IMDB...
