Did you know that thousands* of people have their GPU fans off and the temperatures climb to their 70s Celsius?
Did you know that you should use a OC software even if you're not planning to overclock?
Did you know that by creating a custom fan curve you can increase the lifespan of your graphics card?

Did you know all that? Good! You are one of the informed and this doesn't mean anything to you.

But if you didn't know, go there and grab yourself EVGA Precision X, MSI Afterburner or some AMD thingy that I know nothing about cuz my house is warm enough.

*I lied and I actually have no idea about the numbers. It just sounds nice
Will spice this up after I've cooled my head if you know what I mean. I mean the spice. Not the cool. I'm out.

Do you have a custom fan curve?

Yes
No and I will not make one
No, but I will now make one
I don't have a video card :/

[x] Yes, but only because the default one is too aggressive and unneccesarily loud.

Huh. Well that's funny :D

Or is it? Sometimes things are reversed :O dtE4r

My Gigabyte R9 270x OC has 3 fans. At default they run at 1800 rpm/35% fan speed which is ridiculous. With MSI Afterburner I set it at 25%, slowly increasing the higher the temp gets. Keeps it nice and quiet when not gaming. I don't know why they set the speed so high.
The temps stay low while gaming so I reduced the fan speed.

The new Wattman tool from amd gives a pretty good auto fan-curve.

Btw. also for me i use this tool to make the card more quite. In Idle I'm around 50°C in Games on heavy load it's 80°C (OCed r9 380).
I don't need the coolest card because I'm pretty sure I'll buy a new card every 3 years anyway...

Well, 900 and 1000 series most have 0dB technology and the fan kicks in at about 65C. They usually have about 40-50C in idle depending on wich card you own and thats normal.

My trusty Sapphire 7850 oc edition reach less than 70ºC playing but otherwise it's cool get it? XD

I wouldn't use that curve in the first image. Fans (or their motors) have a minimum voltage (corresponding to a minimum speed percentage) necessary to start them. That dashed line at about 22% speed on the image is MSI's guess at a general minimum speed, but it varies depending on the fan/motor design. I have one case fan that will run at just over 20% speed and another that doesn't rotate until about 40%. Below this setting, the electricity that the fan controller is supplying is energising the fan motor windings and generating heat, but the fan is not turning, so there is practically no air flow over the motor to cool it. If this occurs for long enough, the motor can overheat (the insulation breaks down and it will short circuit). You can figure out what this minimum speed is by trying different speeds and observing the fan. For case fans, this is easier if it has a 3 or 4 pin lead with a yellow wire (as well as the red and the black), and it is plugged into a 3 or 4 pin fan header on the motherboard, because you should be able to get a fan speed reading with the right software. You can muck around with a temporary curve to find out what speed each fan needs to ensure that it is running (make the curve flat at your test minimum speed from 0 degrees C up to well above the current GPU temperature (or motherboard or case temperature for those fan control loops), so that you know the controller will be trying to run it at your test speed. Try a few values until you find out what is the lowest % speed it will run at (keeping an eye on the temperature, and letting the fan run every so often). You don't need to be super accurate - it's best to allow a safety margin to accommodate things like power supply voltage variation and bearing lubricant viscosity changes as it is oxidised and contaminated over time. Anyway, once you've figured it out, you can have this minimum speed set on the fan curve from 0 degrees C to wherever you want it to start ramping up, I start ramping my fans up at 30 degrees C, which is high enough to allow them to idle quietly at or near minimum speed. GPU manufacturers publish maximum operating temperatures on the datasheet, and you want the fan to be operating at maximum speed at temperatures substantially lower than this. Your curve should look something like the one in the image, except the left hand side should be horizontal at your minimum speed from 0 to wherever you want it to start ramping.

The min speed is 20% even if it's below 20%. I got it set up like that because I first made it ramp a percent/Celcius but I decided to max it out at 90C.

Master race doesn't need to curve fans. Fans kneel before us. 🤴🏽

Some cool temps there. Must be good fans.

It's because it's winter here. In summer my GPU idles somewhere between 30 - 33c

I've never used any added bloatware to control my GPU fans (or system fans), and I don't plan to, ever. I've been building my own gaming systems since before GPUs were a thing. In all that time, I've had one GPU fail and it was still under warranty.

My current GPU is factory overclocked and the built in fan curve keeps the fans off until needed, then it kicks in and adjusts them to keep the GPU at optimal temps. As for extending the lifespan of the GPU, I tend to upgrade my GPU every 3-4 years. The warranty period is usually 3 years, so if it fails before then it gets replaced for free, if it fails after that, it's time to replace it anyway.

I let the BIOS control my system fans. Every motherboard I've had in the last 12 years has had similar built in fan controls that let you set custom values for how much power to send to the fan based on load, set a target temp and it will adjust the fans as needed to keep it at that temp, or use some presets. I always chose the silent preset, which keeps fans at the lowest RPM until they hit a certain temp, then ramps them up as needed to keep it from going over that temp. My last two builds have had similar settings and they're still running.
