Nvidia GTX 980ti fan changes speed constantly

[Deleted member 197361]

I used a 5.25" bay fan controller that I had at the time. But I did have motherboard-based control at a later date.

I couldn't link directly to the GPU temp when I had them hooked up to the motherboard. So I told them to follow the "PCIEX16" temerature--which only varied between 45 and 56C.... SOO... I would tell it to start ramping up speed when PCIEX16 temp increased.

Depending on your motherboard, you may be able to link one of your fan headers to the GPU temp, I believe 3 of the fan headers on my current board will follow GPU temp if I tell them to.

What are you specs?

Good idea but I‘m afraid that‘s not possible with my board.
I have a Asus M5A97 LE2.0 with only two fan connectors which are both used by my chassis fans.

another option would be to install a water cooler for my graphics card (because it‘s a poseidon) and simply disconnect the fans. But I didn‘t have time to look for a water cooler and don‘t know what that would cost (and evenwhere I can install the cooling system)

Google is showing me four headers for that board.

So one issue that I ran into when I put the Arctic F9 fans on my old GPU was that it would overheat. 1800RPM was not enough. I had to set the card to run at 80% power draw, it cost a few FPS, but nothing major. Also, the card looked ugly with the shroud torn off, so I just didn't look at it.

It seems you're trying to conserve as much money as possible, which I can relate with. So, I would suggest a couple items like this: Fan hub, two 80mm to 90mm fans in the 2500RPM range. I would go with the ARCTIC COOLING P8 PWM PST, it can be daisy chained, its cheap, static pressure optimized, and has a RPM range of 200 to 3000. Oh, and don't for get a liberal amount of zip-ties.

If you get the Arctic fans, and the small fan hub, you can plug the fan hub into your CPU header, plug your CPU fan and the Arctic fans into the hub, and the Arctics should spin up to a reasonable RPM while you're gaming. If temps are still too high, you can always turn the power draw of your card down to compensate.

Good luck with your journey.
