[Retroman1987]

So my old graphics card, an HD 6870 finally blew up after about 4 years of use. I bought a substantial upgrade, an R9 390 (thank you newegg deals) and installed. Immediately I noticed that temps were way too high for the card under most circumstances. Some research told me it should be running around 30-35 degrees idle and 68-72C under load. This thing is idling about 40c and regularly going over 90 under load, even games that absolutely should not be taxing this beast like World of Warcraft on medium settings or Dota 2. I've also noticed substantially longer load times for a variety of applications which might be due to the heat within the case but I am pretty clueless at this point. I upgraded my power supply just to be sure that wasn't an issue and since I likely needed a new one anyway. Not really sure where to go from here but XFX support is taking forever getting back to me.

Could you specify exactly which PSU it is you have?

Some cards require an additional power input than what is available from the slot itself. Do you have both 6 and 8 pin connectors connected to the card? Without the additional power, the card's built in heat dissipation will not fully function properly.

Would the card even run without full power?

[Rikai]

Yes. But not very well.

Gday.

I think it would be useful to have some readings.

Please download/install CPU-Z and HWMONITOR,  > http://www.cpuid.com/softwares.html

Start HWMONITOR, drag the bottom of the window down so all readings are seen.

Play your game for about five minutes, then take a screenshot of the monitor, save where you can easily find it. 

 

Shut down HWMONITOR and start CPU-Z, take a screenshot and save.

On the top menu, click Memory, take and save a screenshot.

Top menu, click SPD, take and save a screenshot.

 

Top menu, click  Mainboard,   Note down the BIOS ver. and Date.   Close CPU-Z,

Please include the 4 screenshots in your next reply.
