My 7870 Myst seems to be running a little hot compared to other GPUs.
First I'll display some data and then ask my questions ^_^
The following tests I did with FurMark at stock clocks with open and closed case at ~23 degrees ambient (it's still early morning and not so hot YET):
15 minutes "Built-in benchmark" option with open case: Max temperature 75 degrees
15 minutes of the same type of benchmark with closed case: Max temperature 78
degrees
Keeping in mind that during the worse heats I'll be mostly on AC but right now around noon I can hit up to 80/81 (closed case and GPU cooler at 40%) degrees and it isn't that hot outside.
Now for the questions:
Is my case poorly cooled? I will surely be buying a nice side fan that is going to blow almost directly on the copper heat-pipes coming out of the GPU so that should help a bit correct?
Should I replace the thermal paste? From what I gather a lot of people have mentioned a 10 degree decrease in the GPU temps which is insane and many agree that the stock thermal paste is either badly applied or of poor quality.
Here is a source I'm looking at (amongst others): http://linustechtips.com/main/topic/10418-how-to-change-your-gpus-thermal-paste-with-pictures/
So in short:
Should I replace the thermal paste?
Is my airflow bad and will a nice extra 120mm fan fix it?
I have only case fan that is mounted in the back and blowing hot air out. If I place on on the lower side of the case it should blow colder air in and make better airflow correct?
Thank you for reading this and for any helpful feedback
Best Regards,
EDIT: Well I got two very good case fans - one to blow air in from the lower side (the incoming air almost directly hits the copper pipes coming out of the gpu heatsink) and one to blow air out from the top back.
The max temperature I'm getting now is 69 degrees with GPU core clocked at 1200 and memory at 1600
Guess what should have tipped me off on "poor windflow" was the fact that the heatsink and pipes were growing very warm which means that the thermal paste was functioning properly.
