Will using MSI Afterburner ruin the fans' lifespan?

I am planning to do custom fan curve profile on my games. My rig is 980GTX SLI Acx EVGA and when playing Assassins Creed Unity on default fan curve, GPU1 hits 80 to 85 and GPU 2 hits 68 degrees. Upon customizing my fan curves, my fan speed is 75 at 70 degrees and 100 at 80 degrees thus making GPU 1 less than 80 degrees. If I keep that profile playing games 3 to 4 hours a day, will it ruin the fans' lifespan?

No. It just a third party tool to alter things on the GPU with other functionality.
It shouldn't ruin the fan lifespan with your custom fan profile.

Since my fan speed is 75 on 70 degrees and 100 on 80 degrees, what is my fan speed if my temps are 78?

Assuming it is linear with no hysteresis, it will rise 2.5% per degree C (25% of fan speed over 10C)

Now you can figure 78 - 70 = 8*C

8*2.5 = 20% above 75%

The fan should run at 95% at 78*C

Faster fan speed will reduce their life span, but higher temps will reduce the whole GPUs lifespan.
It seems like a fair trade to crank up the fan speed.

Wait, someone said it does not reduce the lifespan. Now you're saying it reduces. Who is telling the truth?

 

[smeezekitty]

It will reduce the bearing life. Faster speed means more wear.
But the fans can be replaced and they still last a very long time. Its not worth roasting
your GPU over worrying about the fan

How many years for the fans to give out if I use my custom fan curve (75 speed at degrees and 100 speed on 80 degrees)?

Don't worry about the fans, you will probably upgrade your graphic card before with the card dies or the fans die.

If I keep on doing that fan curve profile, how long will the fans last? 3 years minimum?

Unknown. No one really test the gpu fans for reliability. It will be fine. Just don't worry how long the fans will last. By 3 years time, there will be better gpu and upgrading will be the more ideal choice then replacing the gpu fans.
