HIS 4870 Fan Control? .XML *trick* not working....

Hello,

I am hoping some of you may be able to help me out.

I recently purchased this card -

http://www.newegg.com/Product/Product.aspx?Item=N82E16814161269

Running GPU-Z the fan stays at a constant 34%. I attempted to bump it up a bit w/ the CCC profile creation, .xml changes. However, they have no effect what so ever.

After a bit of reading around I discovered the fan on the card is 2-wire and non-variable so the .xml changes will have no effect.

However, I ran ATI Tool "Artifact Detection" and as soon as the card go over 60, the fan went up to 45% (according to GPU-Z)

My question is - If I am unable to modify the fan speed w/ the profile/.xml trick (since it's 2-wire, non-variable)....why is the fan speed changing after the card reaches a certain temp?

Any assistance is greatly appreciated!

Thanks,

Rapoon

I'm sorry. I posted this question in the wrong forum.

Could this thread please be moved to the general radeon tech support forums.


Thank you,

Rapoon
 
Enable overdrive in the CCC and you can control the fan speed from the driver now.

Edit: make sure you have the latest catalyst (9.6 as of right now) and click on advanced in the CCC. Then click on ATI overdrive. Click the Lock icon, and you should be able to modify the fan speed from there. I used 40% which keeps mine at around 50C idle.

I have the latest drivers. Advanced mode is enabled.

Overdrive is unlocked. There are no options for controlling the fan speed.

The fan is a two-wire, non-variable speed fan. The speed cannot be manually adjusted.

It's really not that big of a deal. Card was a decent upgrade from an 8800gt. It's running cool and working well.

I just thought it was strange that the fan speed was adjusting itself (according to GPU-Z) once temps > 60.

Maybe the steps/commands are in the GPU Bios. *shrug* no clue.

that looks like the fan on my palit4850 at work, i think it speeds up by usage (maybe detect by amps?) not temperature

the bios might have the fan controls ya... or maybe a fan controller (or mobo port with some software app) could control the speed separate from CCC/drivers/bios

Click to expand...

Yeah, temp goes up, it sends an increased voltage to the fan. Alot like the low end cards... ;-) *E-Cookie to knootcn*
 
i said NOT temperature

i was testing cod5 a couple days ago, noticed the fan speed changing just by aiming at the sky or at something busy, & instant change when going to the menu

forgot to compare in rivatuner though
