Mörkö's Second PowerMac G5

[Dschijn]

Better test under Windows how the temperatures and the PWM signal scale! Seems like the fans get sth like 50% PWM at 80°C.
For OSX you can only flash the GPUs BIOS to modify the PWM values. Or you just be happy with a quiet GPU and good enough cooling

Graphics card casing version number 2 is ready and it might even be the final version.

Nice on the GPU case conversion

Nice. Would like to see some testing under Windows with an eddited fan curve

 

[Mörkö]

Thanks eelhead and Dschijn

And here is some test results under Windows with an edited fan curce.
Still no extra noises and temps much cooler.
I just wish that somewhere is similar program also for Macs.

The only soltution that I know is, that you could flash the BIOS of the GPU with an edited fan curve.

Upgraded Z87MX-D3H motherboard bios from F3 to F6 and Mavericks to 10.9.2 and everything works as it should

Oh wow nice, you actually changed out the fans in the GPU. I never thought a/b doing that, especially using Noctuas for low noise. I just wish they had alternate colors b/c their mainstay is an ugly color choice.

I'm very happy with this Hackintosh, after almost two years usage this works without a single problem
