There is also this: https://code.google.com/p/overdrive5/

yes this worked got it down under 70 degree celsius with 70% fan

thanks a lot

would be cool though if you could set vents to 70% because others may have the problem also and get overheated cards maybe not even noticing

please include fan control option my temperature runs crazy and I cant control fan speed linux due to R290 newest drivers

where can I find new version? 1 post isnt that the old one?

Guys,

We are experiencing overload in some of our subsystems, this is why your hpm has dropped. It is not related to increased difficulty.

Things will get back to normal in under an hour, stay tuned!

ah ok many thanks
could this be also the reason for hanging miners ? becaus I have this today but not yesterday

There is a 20 - 30% drop in performance for me since yesterday

is this due to increasing difficulty? or do I have issues with my cards?

Check the temperature with:

Code Select Expand

aticonfig --adapter=0 --od-gettemperature

and fan speed with

Code Select Expand

aticonfig --pplib-cmd "get fanspeed 0"

If the temperature is too high, try setting the fan speed like this:

Code Select Expand

aticonfig --pplib-cmd "set fanspeed 0 80"

In Windows world they have all those fancy GUIs ;)

my problem is I get
PPLIB command execution has failed!
ati_pplib_cmd: execute "get" failed!

and with cgminer i have no problem with these cards runing at 70% fan speed with 76 degree
thanks for all your help!!

Since aticonfig doesnt allow me to control the fan at the 290 cards, I use now following solution to protect against the temperature run to 94 degree.
I first start cgminer and when card reaches arround 76 degree and 60-70% fan rotation I quickly switch to memory coin miner and the fan stays at that rotation speed.
It seems to me the auto speed of the cards is set way too low around 43 % fan rotation.

could you add an option to control the vents rotation on card

thanks in advance

Perhaps, in future versions. Driver's autotune might work just as well in most cases: card's cores are not always loaded to 100%, during periods when most time is spent accessing memory, cores have a chance to cool down.

thanks a lot I fear only that 94 degree ist too hot for my 290

Some people have reported a much cooler operation than with scrypt, and a lower power consumption.

yes you are right on my saphire its 67 but on ASUS card its 94 which is very sad

my 290 run at 94 degree celcius normally with scryt and fan mangement  I run them at 76
