Hello everyone, I'm a long time reader, first time writer to this forum. I recently purchased an XFX r9 270x graphics card mostly for gaming and some occasional bitcoin mining just for fun. I use bitminter bitcoin client. Now my question/problem is, Ive never had a problem with high temps when i used bitminter with an hd 7750, But now soon as i turn on the bitminter client, my gpu shoot up to past 90c till the computer shuts off. I have tried down clocking but that hasnt worked. My next idea was to replace the thermal compound in the gpu. If you have any suggestions or know what might be causing these problems, please let me know. Thank you!
