2 Here & no noise

Enthuziast
My hybrid doesnt make any noises.....some ppl are just paranoid lel.

The radiator fan that came with my 980Ti Hybrid is LOUD. In fact, the 970 it replaced didn't make as much sound at full load as the 980Ti Hybrid.
 
And since the radiator fan is not temperature controlled in any meaningful way, it's loud all the time. The 970 it replaced spun down all the fans when the card was idling, making zero noise. The 980Ti converted my otherwise rather quiet box into a small Cessna, and gave me flashbacks to the black Delta fans.
 
I replaced the stock fan with a Noctua NF-F12 PWM and plugged it into the motherboard so it can be controlled. That reduced the noise levels to the same as the 970 at idle (the radiator for my 980Ti Hybrid replaced a case fan). On the bright side, it's now just as quiet during full load, which was what I wanted from a hybrid unit...
 
Let's just say this is not what I expected from a premium priced product.

Hi, could you just tell me how temperatures on your motherboard control your fans?
 
My motherboard has some stupid "Ambient temperature sensor" which is just a random sensor that is at 40 Celsius sometimes and 60 Celsius at other times. What kind of fan curve do you have? What do you use to make your fans spin up and down? Could running my fans at 700-800 RPM give me proper temperatures during gaming?

These past three responses are exactly what I was hoping to hear as I have two Hybrids on the way.  I also plan to replace the stock fans with Noctua.  I understand the want for a premium products stock fans to perform better.  But, I must say after finally buying some Noctua's and trying them for myself there is no comparison to any other fan I have ever used.  They are that good.  Regardless of that, I was also going to use my MB fan headers to control the fans so I'm not surprised some are disappointed with the noise if they leave them plugged in through the card.

My motherboard has this fan controller software thing, so I just set up curves based on that. I've attached a picture of my setup for the radiator.
 
So far I've only stressed the card with GTA V, my CPU temps peak at 70C and GPU temps at 50C with ~40-50% CPU load and >95% GPU load (~22C ambient). I've not spent much time tweaking the curve though, just got the card a couple of days ago.
 
The temperature the fan controller uses as basis is the CPU temperature, however at work I have a newer motherboard from the same manufacturer which I noticed allowed me to select which source to use (CPU or motherboard temperature).
 
Sadly the GPU temperature is not entirely correlated to CPU temperature, but fortunately for me I don't have many workloads which stresses the GPU but not the CPU. I'm keeping an eye on the GPU temp though while gaming, so might tweak the curves a bit.

I'm not complaining that the Noctua fans are better than the stock fans. I'm complaining that the stock radiator fan is not temperature controlled in any sensible way (if at all!!!) and that it is loud. The stock fan on my H60 was a bit louder than the Noctua, the stock radiator fan on my 980Ti is about as loud as a small airplane. If you buy a hybrid solution it's because you care about noise, and when I pay a premium price for a hybrid solution, I expect a considerably better product than what the 980Ti hybrid was out of the box.

That's a bummer, my motherboard only likes me using the motherboard temperatures which are really inaccurate. I'm hoping my cooler manufacturers create a software that can control motherboard fans. I'm just gonna keep my fans pinned at 800 RPM then it seems.

To be honest, I might use a fixed speed too down the line, as it'll be more predictable, as well as not fire up if I do x264 encodings for example (a pure CPU load).

Yeah, same here, sometimes YouTube will make my GPUs a little warm and suddenly my motherboard temperature will spike and cause all fans to spin super loudly. I'm just waiting for NZXT to come out with their motherboard fan control on CAM.

In Google chrome, disable the hardware acceleration feature. Go to settings on the right side, then to the bottom and select advanced settings. Scroll to the very bottom again and the next to bottom selection should be hardware acceleration. Disable that and it won't try to use your gpu for browsing.
