Is this normal? (GPU, PSU or MOBO problem?)

My EVGA 980 Ti SC ACX2.0 has been having RPM spikes, I don't hear the GPU Fan's getting louder as you can see here even when the spike occurs it jumps from 2000RPM to 4000RPM for a split second but the fan speed % doesn't go up at all, does that mean this is a bug? occasionally I also notice my case fans doing this in BiOS, i'm using 3 pin splitter to put 2 fans on each header, total of 6 fans on the motherboard (MSI- x99a Gaming 7)

hypothetically speaking if this was a motherboard sensor issue it wouldn't make sense for the GPU fan's to spike since the GPU has it's own sensor, so could this be power supply related?

If you are not hearing them spin up maybe they are not and it is just a software glitch. I would actually be surprised if the fans would reach 4000rpm on the card.

I took out the card and put it back in and was able to play 5 whole hours before it spiked 1 time, before it would spike every 2-3 minutes, what could have changed?
