GTX 580 fan help
 

I purchased a used GTX 580. It produces good double-check results unless it starts running hot.

The problem is that I can't get the MSI afterburner fan settings to "stick". I've tried setting up a user-defined curve and running at a fixed 90%. The fan settings work as long as afterburner is running. If I close afterburner, the fan goes back to "auto" settings which are inadequate. I'm not sure, but if CUDALucas stops and restarts the fan may also revert to "auto" settings.

Has anyone else seen this? Better yet, anyone with a possible solution?

[URL="http://www.evga.com/precision/"]EVGA Precision X[/URL] can apply clocking and fan speeds at start-up and when it is closed (or appears to be, at least). It's what I use with my ASUS GTX 560.

As far as I know, Afterburner has to be running full time for its effects to be sustained. I have always run it set to start with Windows, with "Apply overclocking at system startup" ticked on the front panel.

EDIT: I just verified that this is the case for me. Stopping Afterburner caused the GPU temp to rise as the fan speed decreased from 2800 to 1800 RPM in the minute or so before I restarted Afterburner.

It seems that, if the EVGA software continues to control fans and frequency after it is shut down, then it must have some persistent background task to do this.

EVGA won't allow download of that utility anymore. I did find another site to download from, but it is the same thing as MSI afterburner with a different skin. It has the same problems.

I'll try running MSI afterburner all the time --- seems like a waste.

My experience with EVGA Precision X and MSI Afterburner is that settings stuck. Overclocks always do. Fan settings VERY occasionally do not. Voltages rarely do.

:loco:

You could try the BIOS for fan control settings. That's what I had to do for my pump since Speedfan couldn't control it.

Actually, now that I think about it, you could actually try Speedfan.

Looking a little further, I find that over and under clocks (GPU and VRAM respectively) are maintained when Afterburner shuts down. I can't say right now about voltage changes, as I'm running at stock with that part of Afterburner disabled. Unfortunately, the fans went into an immediate decline.

The inadequate fan issue first came up with a particular nvidia driver release a year or so back. However, I think it must be BIOS related as well. I have an Asus 580 and a Gigabyte 570. The Asus card has a real problem with running slow fans and hot GPU (as in hitting the throttling temp.) The Gigabyte does not do this.

As an aside, I think the Gigabyte cooling solution is superior to the Asus. The Gig. has 3 75mm fans, while the Asus has 2 95mm fans. The Asus fans run faster, even though both cards have about the same top fan speed. They are also much louder than the Gig. fans. In addition, running on the custom fan curve in Afterburner, the Asus hits top RPM at about 70% PWM. While the 580 [I]may[/I] put out more heat than the 570, I can't be sure, especially since the 570 has a much higher factory OC.

Of course, its hard to say definitively which card is cooling better when both are in the same case and feeding heat to each other.

Brand/Part Number of the card will be very useful here. Some Asus DC2 cards could not care less about afterburner, etc, and you would need to use their (Asus') tools. So, what exactly the card is?

(edit: Asus's "doctor whatever" asks you, when you close it, "do you want the fan settings to be kept, or revert to default", or something like this, and it works well for Asus cards)

It is a non-overclocked EVGA 1.5GB memory. I can get the exact part number if you need it.

I don't need it, I only was afraid it can be an Asus card, from which I have few and know they are not so responsive to third party tools. Sorry I can't be of any help for EVGA. I have a Titan, which works well with PrecisionX, and I (most probably) have the tool downloaded somewhere at home, I can pack it for you in case you can't find it.
What is the problem with letting the Afterburner (or the tool you use) run in background? If this solves your problem, just minimize it, and don't close it.

I'm trying it now. An inelegant solution, but tolerable I guess.
