3070Ti Fan curve issue

I've managed to grab a 3070Ti to upgrade an old GTX970 :eek: !

Did a driver uninstall and installed the newest Nvidia Experience Center with updated drivers, I've got X1 Precision installed as this controlled the old 970 fan curve perfect.

Now whatever I set fan speed wise the GPU is constantly going over the limit I set so the fans ramp up to 100% when the temps hit 80c. Is this an issue with the newer cards? I've also tried the manufacturer's app and this does the same. The only way to stop the fans hitting 100% is setting the power limit to around 90%

I'm stumped :confused:

What model of 3070Ti is it and does the card work normally when there no manual fan curve set as a card should not be hitting 80c / 100% fan speed unless theres some issue with it.

Oh and a lot of newer cards dont turn the fans on under 60c but I'm not sure if a manual fan setting would overide it.

my 3070ti (Gigabyte OC) runs well through MSI AfterBurner, and yeah it does override the 0 decibel feature too (there is a checkbox to apply this).
 
This is the card I've managed to get https://www.overclockers.co.uk/kfa2...ddr6-pci-express-graphics-card-gx-0am-kf.html

It was extremely cheap so hard to resist. I've figured the cooler probably is pants but I can live with 80c temps the fans are around 40% under but soon as 80c reaches they hit 100% and bypass the custom curve I've set. I may see if there is a bios update for the card.

All benchmarks are spot on for a 3070ti so it's not throttling or anything like that.

Looks good enough a GPU mate. Strange situation though with the fan curve. Im not sure on it.

I use the BIOS for the CPU / case fans and then when Windows loads in, MSI AfterBurner for the GPU temps.
 
I can see a 30% lower limit on the software and this looks normal for a 3070Ti but I have it set to max 45% this seems the best for noise/performance. But after hours of gameplay it occasionally hits 81-83c then it fully ramps the fans to 100% cools down then 100% this only stops if I limit the power % it's almost like it's hard coded temp limit on the GPU once it hits that there goes the fan curve ha! Strange.
 
I think a lot of cards have a hard-coded max temp, so when they hit that, they'll do whatever fan speed is necessary to bring them back under. I think that's how it works.
Maybe you could come up with a curve that prevents it hitting that by kicking in like 70-80% at a lower temp ?

Yes, some fans will not work if you attempt to drive them below 30%. With come cards the moment you take manual control you are doomed to running the fan at a minimum of 30% ( in other words you can never switch it off ). Some cards you can. But this does not explain why it is behaving oddly.

Have you tried monitoring the GPU temperature in Afterburner Monitor Display to see the correlation between actual temperature and the fan speed to check to see it is actually following the curve? It could be there is an issue with Afterburner reading the GPU temperature.

I don't understand why you have set it to max 45%. You should set it to ramp up to 100% at say 80 degrees. And yes, it's probably a safety feature in the card that is taking over.

I think it's just habit of having a near silent PC with the 970. I couldn't hear any fan noise at all. Going to this been ramped up to 100% is a bit of a shock so I limited it to 45% as it seemed to stay stable at keeping the temp around 70-75c and it kept the noise down to near enough 0. No matter what the curve is set at the card hits 80c then 100% fan speed. I'll have a look at my case fans tomorrow and do some experiments to bring the case temp down.

If I let the card do the fan speed it's all over the place ramping up then slowing down, I think I'm just used to a constant fan noise at a set speed if that makes sense?


Maybe I'm over thinking this :D

What I think we're all suggesting is try a fan curve that gives it a lot more than 45% but less than 100% at some point before it hits 80 deg, so it doesn't get there & isn't provoked into ramping up to 100%.
Of course, the cooler might not be up to that task, but it's worth a try.

I do that but also set the FPS in the NVIDIA Control Panel on a per-game basis to set the noise level to something acceptable.
 
After playing with fan speeds I gave up, couldn't get it to play ball. Cant seems to control the GPU at a respectable noise level not to hit the 83c hard limit. Decided to watch a few tutorials in under volting, gone to around 880mv with a +900 on the memory. Max temp now is 73c with the fan at 1300RPM. It's now sorted! Just leaving Heaven playing a few more cycles to double check the max temp. Go figure, it's quicker and quieter! :cry:
 
Well after nearly 24Hrs of playing around, case fan speeds under-volting the GPU I think I'm happy now.

Temps do not go above 65c !

Nice upgrade from a 7 year old GTX 970 oh and a 5600X to replace an old 3600 :D
