XFX 4870 fan speeds

[pantherx12]

Hey I was wondering if there an easy way to set default fan speeds, I'd rather have the fan running @20% when idle and also kick up speed in general a bit faster.

My temps very quickly get to 70 celcius and the fan still doesn't bother to go over 40%.

And help greatly appreciated.

Yea man if you go into the ati ccc panel and have it on the advanced settings and go to ati overdrive then click the lock it will unlock the manual settings then click the enable ati overdrive box, this will allow you to change the clocks as well as the fan speed. If you dont want to overclock your card make sure the sliders are at the default location meaning all the way to the left and just set the fan speed, hit apply and you should hear the fans kick in.

Thank you but I meant it the fans to still automatically be controlled, do you know how?

you mean like have them at 40% then go to say 80% when you're in game?

well i know rivatuner does this extremely well...it has 3 seperate settings i think they are 2d low 2d high and then 3d...if you dont want to mess with rivatuner you can try this...

WOULD YOU LIKE TO ADD FAN SPEED CONTROL TO CCC?
THIS WILL WORK WITH ALL CARD THAT HAVE temperature sensor E.G. 3870

This works on Catalyst 8.10 and above

Temperature sensor: If your fan has more than 2 wires

THIS WOULD REQUIRE YOU TO EDIT THE REG.

PLEASE BACKUP YOUR REG!!!!

START -> REGEDIT (RUN AS ADMIN) -> HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet-> CONTROL -> CLASS -> {4D36E968-E325-11CE-BFC1-08002BE10318} -> 0000 (be sure to tweak your CURRENT drivers key MINE IS 0000)

THEN LOCATE AND EDIT THE VALUE DATA FOR EACH BELOW TO (2)

FanSpeedPercentActual_NA
FanSpeedPercentTarget_NA
FanSpeedRPMActual_NA
FanSpeedRPMTarget_NA

SO AFTER THEY WILL ALL HAVE DATA VALUE 2


EXIT -> REBOOT -> GO TO CCC -> OVERDRIVE

OR A SHORTCUT

OPEN REGEDIT -> FIND: FanSpeedPercentActual

THEN YOU WILL SEE THE 4 ABOVE RIGHT UNDER EACH OTHER
AND EDIT THE VALUE DATA TO (2)

EXIT -> REBOOT AND ENJOY
