  1. Doesn't work, i even tried flashing different VBIOS images and modifying the VBIOS to no avail. I am certain that the IC has gone bad, from what i know the issue manifests itself after 6-7 years of use. Luckily it doesn't throttle. That reminds me something about the issue i have with the PWM signal of the motherboard header, I can clearly hear each and every duty cycle which is annoying, in theory could it be solved with a frequency increase? At 100% duty cycle the fan is too loud but at least the fan doesn't ramp up and down every duty cycle Can that be an issue? How do i do that?, just a diode in series?, also what diode should i use? I will power it from the motherboard.
  2. As far as i know it's a common issue with those cards, The ADT7473 is not just a PWM controller, it also monitors the temp sensors and reports the thermals. So the temperature reporting is also affected (On some sensors it reports 1,000C, on the GPU core it reports crazy low values like -2,147,483,648C) Examples: https://www.reddit.com/r/graphicscard/comments/ocqs5i/my_diagnosis_temperature_sensors_in_gpu_are_hosed/ https://forums.tomshardware.com/threads/radeon-hd-6970-fan-is-spinning-at-very-high-rpm.3365747/ https://forums.tomshardware.com/threads/amd-hd-6970-reports-128-c-and-fan-at-100.2638437/ Also i wouldn't throw a card for such minor issue just because it's cheap on the 2nd hand market, It's a waste.

  4. So the PWM controller on my HD 6970 is dying and started freaking out, So i made an adapter and connected the blower fan of the card to the motherboard, but the PWM signal from the motherboard is not good for this blower fan. Now i don't really now what to do, I thought about using something like a rasperry pi or arduino to provide a PWM signal to the fans. But i don't know how the signal should be since i don't have a HD 6970 with good PWM signal to measure. Is there a way to ensure that the duty cycle and RPM are synchronized? If there is a better way to do it i would like if you let me know
