Question GTX 1070 Really loud - one fan is a lot slower than the other two

[saltySquash]

My 1070 has started getting really loud suddenly, and i think it's because the two other fans are running faster to compensate the speed. It can be pretty quiet for one second and then suddenly it's just as loud as an old washing machine. From the data i've been able to access, it looks like the third one is running at just 120 RPM, while the other two is fine.

What's the make/brand of your Video card ? Is it a triple fan air cooler ? Which Power supply unit are you using ? Make sure the GPU is properly seated firmly on the PCI-express slot, and all the PCI-E cables are connected as well.

When does this behavior occur, fans spinning randomly ? In IDLE desktop Mode, or when you play Games ? How OLD is this Video card ?

Asus, Yes triple fan, ts 550 xfs sew, i've checked,

It occurs when playing almost any game, and sometimes on the desktop, it's 4 years old.

I'm considering to buy a RTX 2070 to replace it, do you think that this power supply would be enough?
And i'll also order a new fan for the 1070 and see if that would fix it, then sell it maybe.

[saltySquash]

I think it's called ts 550w xfs

Is this your PSU model ?

Yes that's the one.

Okay, then most probably this looks an issue related to the GPU itself, IMO. Maybe the card is faulty ? But I'm not 100% sure.

But do you think that my PSU would be able to supply RTX 2070?

 

[Metal Messiah.]

Well, I think your current PSU is okay, and for the RTX 2070 Nvidia recommends a min 550 Watts PSU. Though, if you can upgrade to a higher Wattage PSU, then it would be much better, for some extra headroom.

But I think that XFX PSU is a decent power supply, IMO, though I lack knowledge when it comes to power supplies, so I'm not sure !! The Moderators, and other forum members might be able to guide you much better than me, since they have good knowledge about PC/hardware.

Today the fan is running smoothly again? All i did was setting the fan speed a little bit up in Afterburner. Isn't that weird? And all the click and scratch sounds and loud fan noise stopped. What is the optimal setting for fan speed, right now i have it on 52%, and it seems to work fine.
