B580 Limited Edition fan tacho signal

[dereksgc]

Hello, I wanted to ask if the pinout of the J1011 and J1013 connectors on the Limited Edition B580 card PCB could be made available, or if someone has already analyzed it, in order to access the physical cooling fan tachometer pin(s), to get an RPM readout without the OS, or alternatively if a test pad with the tacho signal is available anywhere on the board.

I would also appreaciate if anyone knew what type of connector is used on the board, that way a breakout could be made without having to solder on the PCB itself.

I am guessing the J1011 is the fan header since it has eight pins (2x4 fan header?) but I could not find any specific information about it online.

Thank you!

Hello dereksgc,

Thank you for posting in Intel Communities.

I understand you're looking for the J1011 and J1013 connector pinouts to access fan tachometer signals for hardware-level RPM monitoring.

This detailed hardware documentation would need internal review, as PCB schematics and connector specifications are typically proprietary. To help route your request properly, please provide:

1. What's the intended use case? (custom cooling development, research project, hardware monitoring, etc.)
2. How will you use this connector information?
3. Is this for personal use, academic research, or commercial development?

Understanding your specific requirements will help me determine the appropriate channels and whether this documentation can be shared.

I appreciate your interest in our hardware's technical aspects and will do my best to assist once I understand your needs better.

Looking forward to your response.

Best regards,

JeanetteC.

Hello, 

thank you for the quick response. This would be for my personal use, to interface with a fan and thermal monitor built into the computer case. It's a computer that's expected to switch/reinstall its operating system often, and as such a simple hardware tap like that is a lot more practical than a solution that would involve an OS-level RPM readout fed into the thermal monitor through some intermediary microcontroller and PWM simulated tacho signal (assuming that the hall effect/tachometer output of the GPU fans is the same as is standard with ATX cooling fans).

I might feature it in a monetized YouTube video though not as the primary focus, it would be a one-off modification with no further commercial use, although in my personal opinion making the connector pinouts and specifications public could also be quite beneficial whenever someone needs to do a fan repair or replacement on their GPU.

I also understand that this is something that could be inferred with an oscilloscope but I figured going through an official like this would be a better way of doing it, in case there are some caveats that might not be obvious at first glance.

Thank you and best regards,

Derek

Hello dereksgc,

Thank you for the detailed explanation of your use case.

I understand this is for personal use with your custom thermal monitoring setup, and I appreciate you seeking official documentation rather than reverse-engineering the connectors. Your point about potential community benefits for GPU repairs is also noted.

I'll work on this request and will get back to you once an update is available, though the review process will take some time.

Thank you for your patience and for using the official channel for this inquiry.

Best regards,

JeanetteC.
