So your GPU's minimum is 20% PWM? That may explain why my fan is always running. EDIT: I just redid some tests. GPU-Z says "Fan Speed (%): 0%", but the fan keeps spinning at 300-400rpm. When the card is under heavy load, the "Fan Speed (%)" goes up, and the fan is running faster. This seems to work ...

When I use a fan, there's no need for Morpheus II. The Accelero S3 along with a single 300-400rpm fan is enough for the RX 570 under full load. I tested that with FurMark while connecting the B12 to mainboard fan header and setting a fixed fan speed in BIOS. Why do you think that the Accelero S3 is ...

Yeah, like I said: The Noiseblocker fans (one with PWM, one without PWM - doesn't matter) always run at constant speed. I thought: When the card uses Zero-Fan there should be actually ZERO Fan Speed, but the B12 fan still runs. Though I have 2 theories: 1. The PWM is different from what the B12 expe...

As I said: I was pretty close to working perfectly. By undervolting the card it went from 135W to 105W peak in Heaven Benchmark. In 3D Mark SkyDiver it went from 133W to 113W peak. I also tried running a fan on the Accelero S3 using an Adapter (directly connected to the GPUs Fan Port). Something lik...

Hi, I have a 100% passively cooled PC (signature). And now I want to add a graphics card. I already tried a Sapphire RX 570 ITX with lowered Voltage (@ stock clocks) using an Accelero S3, but the card keeps overheating under heavy load (Heaven Benchmark, Valley Benchmark, 3D Mark). The cooler alread...
