RX 460 - GPU fan doesn't work! How do I fix it?

Question asked by terryspeed on Aug 24, 2016

GPU: PowerColor RED DRAGON Radeon RX 460 2GB GDDR5

CPU: AMD FX-8120 3.1 GHz

Motherboard: MSI 760GM-E51 (FX)

RAM: DDR3 8GB

PSU: 560W

Operating System & Version: Windows 10 Pro 64-Bit

GPU Drivers: 16.8.2

 

The GPU fan on my rx460 briefly starts when booting, but soon stops and never picks up again.

The card gets really hot (75C+) yet the fan doesn't even start. It caused crashes in games, & sometimes the screen turns off for a few seconds. I also got "application has been blocked from accessing graphics hardware" errors.

Previous card was AMD Radeon HD 4670 which uses about 70-140W, while the RX 460 uses less, so I guess that's not the problem?
