What's a good agressive fan curve that won't kill my GPU's fan?

[IkusaTakuma]

I got MSI Afterburner a while back because my dad wanted to put custom settings on my GPU (back when he still did the upgrads for me, eventually I learned to do it myself), he set the fan to never exceed 40% speed even if my GPU hits high temperatures (He hated the sound of a PC under load, my PC now is in a different room so it shouldn't matter anymore). The result is my GPU frequently hits over 80C, I don't think temperatures above 80 are OK so I wanna make a custom fan curve.

how aggressive of a fan curve can I go without ruining my GPU's fan?

I would say around %65-70 would be max i would go since above those speed levels your GPU will sound like a jet engine so i wouldn't prefer to run them at %100 during gaming due to noise.

I use some really good noise canceling headphones, and what bothers you probably won't bother me, the question, is how high without damaging the GPU fan?

Fan should be alright, there can be extra wear on fan but i dont think it will matter a lot. If noise does not bother you sure thing you can set your fans max

Full speed. Fans are rated to run at their full speed.

80-85C is perfectly fine. No need to turn up the fan speed. You could change the thermal paste on it though if you can. THat should drop temperatures quite decently.

Not fine for a EVGA 1060 3GB imo its a single fan design the speed drop can be noticable. Im not sure if he got 80C on %40 fan sped though. If so increasing fan speed will help a lot also agreed on paste change.

Consider your PC Case and it's current fans...

Airflow should be split, say you have:

- 2 front intake fans
- 1 top/rear exhaust

The graphics card splits the airflow, so the top area of the case has a fan exhaust, but the bottom area of the case is using the graphics card fan exhaust.

Firstly ask yourself if there's anything else down the bottom area which also needs cooling?

- Around 45 degrees you would want the fan at 40%
- 50–60°C: 55%
- 60–70°C: 75%
- 70–80°C: 85%

Ideally you want the fan to run around 55% for ideal cooling and silence. Then it should just sit around there while you game away. However, adjust this accordingly to your own PC Case and number of other fans, etc.

Yeah that would be pretty dang cool, combine some high-airflow fans and I'd be getting some decent thermals :) But considering I'm going to be upgrading my GPU pretty soon, I don't personally think it's worth my time, or at least, not until I get my next GPU.

I don't know what gpu you have so this is a suggestion only.
As other have suggested don't worry about the fan.
I've been using AB for years and found the best starting point is
a straight line from 40c 0% to 80c 100% for my RX 580. This keeps my gpu quiet when doing desktop stuff and then ramps up while gaming, usually settling at 60c at 50% ish.
You can delete control changes by highlighting them and hitting delete.
Speed update every 4 seconds
Hysteresis at 3c
Force fan speed update each period.
After a game take a look at the AB HW monitor graph and tweak from there as every gpu is different.

running your fans at 100% for months can wear out the bearings quicker. think miner cards

It highly depends on the quality of the fan in question.

Mining isn't comparable to gaming. You won't game for months at a time. If you do, then you need to admit you have an addiction and seek help.

I would not recommend running your fans at a fixed speed. Sure you can run your card at 80°C, but that could wear the material much quicker than at 10-20°C lower. If you have a semi-decent aftermarket card, running the fans a bit more is way better than letting your card sit at 80 degrees.
I also used a custom fan curve on my old 1060 and now on my 1080 Ti: usally I set a 20% fanspeed from 0 to 40 °C and then increase the fanspeed to 60% until 70°C. After that a steeper line up to 100% speed at 85°C.
You can also deactivate your fans below a certain temperature, but my guess would be it's more stressful for the fans to start & stop spinning vs always spinning at min 20%.
You can always tweak the curve to your liking, but I would alyways aim for <40°C in windows and <70°C in games.

you should slap a industrial fan 12000-20000 rpm should sufice just make sure you bolt everything down first

[_I_]

0-10% at 60-70c to 100% at 90c
will be silent at idle, and loud when hot

also adjust case fans curves in bios if using pwm or voltage control fans
50% at 50c to 100% at 80c
will make sure any warm-hot air in the case is exhausted
