Question Fans on 2080 go to max speed at 70 degrees

[josh.springer24]

I've had this problem for a long time and can't seem to find a fix for it. I have an EVGA 2080 Black edition gpu and for some reason the second the gpu hits around 70-72 degrees it goes full blast until temps drop. But once the fans slow down it goes straight back to 70 so it's a constant cycle of the fans going max then slowing down. Was just hoping there is some way to fix this. I have tried manually adjusting fan curves, the fans just completely ignore it.

What software are you using, and what brand is your mobo?

Didn't realize the mobo wasn't in there. I have an msi one and I've tried both precision x and msi afterburner

So do you have any msi software installed for your mobo? I have a gigabyte mobo and their software, if improperly configured (ie not disabled for fan speed control) will override afterburner, etc.

I would look through your programs and task manager to see if it's there and running in the background.

Try hwinfo and check gpu hot spot. Also check the several performance limit reasons - see if the thermal reason gets flagged.
Under load, of course.

Well the post shows that they are already monitoring their temps, hence the specific temps listed at which the fans ramp up. This is a fan curve issue, not a high temp issue. Must be a software conflict if the afterburner fan curve is not working.

I know Afterburner does not display gpu hot spot. Maybe Precision X does, but I'm not familiar with it.
The fans running full blast at that specific temperature can imply that there is a thermal issue with the hot spot sensor, although gpu core can be fine.
That's why I suggested hwinfo.

I've had custom fan curves not work before with my cards, but what always does work is the slider in Afterburner for manually setting fan speed. I'd suggest trying that just to make sure that software control can work with your card before really jumping through hoops trying to resolve the issue.

I use hwinfo and GPU-Z as well. It has a more streamlined sensors tab that shows the gpu hotspot.

I still believe that another program is overriding afterburner. The gpu fans should adhere to whatever the curve is set to, regardless of temps - unless the bios has a built-in override feature above 70° C in evga cards.

Fan curve will be overridden if hot spot is 100C or higher. Seen/read it in other threads.

I didn't notice this at first but it looks like my fans don't run at all until they go max speed. I downloaded the software you mentioned and the fans go max speed once the hotspot hits 100C. Do you know how I'd go about fixing this

Do you know how I'd go about fixing this

Gpu die just needs a repaste, is all. The process is a bit more selective about the paste used, compared to cpu applications. Some pastes are too fluid in texture to be used on bare silicon dies, that they roll off, or are pumped out with hot and cold cycles.
If you have some Arctic MX-4/6, NT-H2, or some Thermal Grizzly Hydronaut lying around, use that.
[These aren't the only options, just some that I know work. I personally use NT-H2.]

Or have someone else do the repaste for you if you're not comfortable taking the card apart and doing it yourself.
