How to get about 50% fan speed on 4870 with RBE?

[goitalone]

I flashed my bios using this tutorial and used what he used as the values but its not cool as the CCC fan profile edit where I had it set to 50% manual.

I just need to know how to get the bios to pump out approximately 50% fan speed at all times for the minimum speed.

Right now at 53 C idle, but with the profile edit, I was at 39 with 50% and that is what I would like to get int he bios. I do not want to flash the bios again until I know how to achieve this.

Thanks if someone can help!

EDIT: I am talking about using the "Use transfer function" function I mean, not the table.

Do I just use 50% Duty Cycle min. with whatever I choose for Tmin?

Thanks, I don't like that program tho and I already have too much stuff running as it is.

What I ended up doing was I set it to 8 Tmin and its right where I want it now at 3300 RPM on Everest and now I am back down to 39-41 C temps

just hope thats ok and won't mess anything up

Heres a song for your help though

EDIT: OK, so it's actually a song for me lol

you can run the rivatuner fansettings without having to run rivatuner tho, but if you dont like the program use the bios.thanx for the song
i prefere rivatuner ´cause it´s a bit smoother then the bios tweak

Welcome, and again, thanks to you too for the replies

you can also try to use the powerplay bios from Fastmix which also helps to lower your temps
you can find it here in The 4870 "2D Low", GPU voltage/Memory clock rate Bios Thread

 

[goitalone]

powerplay in the bios? how does that work exactly?

 

[Fastmix]

if you want 50 at all times, use the look up table and set the fan speed for all value at 50.

Cool, I'll try it...much appreciated!

Wait...what do I use to flash the .bin files? Will ATIWinFlash work?

 

[goitalone]
