I have an RX 460 4GB. After playing 5 minutes of Fallout 4 or Just cause 4 my card reaches a temperature of 84C. I have the single fan version of the card and it is without the 6 pin connector. Is this a driver issue? My case is a carbide 100R with two fans so airflow is not a problem.
This is not normal. The fan on the GPU may not be working properly. With WattMan, the fan settings may not be set properly. There may be thermal paste problem. Speed up the fan with WattMan, if the problem persists, replace the thermal paste or send it to the warranty.
You're right. The driver prevents the graphics card from exceeding 84. Additionally, you may experience the FPS drop problem. I hope you can solve the contact problem. There are manufacturers who do not use strong arcs for GPU connectivity but this problem seems as if there is no contact at all.
