Question GPU Fan stops under load

[FrogDog23]

I have had an RTX 3060 for 1 year now, with no issues. Recently it will spin 1646 RPM when I boot up my PC. As soon as I start a game the fans shut off, causing my GPU temps to reach 95c +. This also causes massive performance issues, I am lucky to get 30 FPS in CSGO.

This is a ROG prebuilt PC, Asus RMA basically told me to go screw myself several times, I am not sure if I need a new GPU or not, looking for advice before I spend some money.

I appreciate any responses!

Does it respond to MSI Afterburner if you set a custom fan curve?

It does not, I actually never used it until this issue started. I tried it and it did not work, I have uninstalled it to remove any influence it might have.

What power supply is in the unit? If it comes down to having to buy a new card, I might be tempted to do the old method of pulling the shroud and existing fans and zip tying a couple of 120mm case fans to the heatsink and see if you can use a coupler to attach them to a motherboard fan header where you should be able to control fan speeds. Just not sure how much the gpu would like not having fans plugged into its own header.

I have the same problem with my RTX 2070 Super. It never did this before, but the fans just stop whenever the GPU experiences a significant load. That is the opposite of what I want! X ) Afterburner shows the GPU fan speeds increasing as they follow the temp curve upward, but the fans are not spinning. Immediately after exiting the game, the fans obey Afterburner. I tried updating my BIOS, but no change.
