r9 380 trottling at 80C degrees in Video Cards and Monitors Posted March 27, 2019 Hey there, Welcome to OCC. Well there are a few options. Firstly is the card starting off at a really high temp at idle or is the card climbing up to this? Does the case have sufficient airflow? Have you tried replacing thermal compound? Have you used a OC utility to input a more aggressive fan profile? Is the fan working at all? If you wouldn't mind presenting a bit more info it would be helpful. Things such as; what video card it is specifically and under what conditions this occurs. More info please. Ill keep an eye this topic and if I have any suggestions ill be in touch.
