Hi, could anyone offer me some advice please on max temps for the HD7970? I've oc'd up to 1125core 1500vram and temps running @ 89c with fan speed 60%. Was thinking of creating custom fan speed profile to keep it lower than 89c if that is a little too high for the card?

HD7970 Safe Max Temps

I would say it on the high side that temp is it after gaming or benching?
If your card an AMD reference one most reviews show up to 78C under load?
If you can stand the noise increase the fan speed and creating a custom fan speed profile to keep it lower than 89C.
What is yout temp with no O/C on the card?
Do you have a case with good air flow?
I would run HWMonitor to check what other temperatures are inside your case.

That idle temp is high I would expect high 30C or low 40C.
That must be with a low fan speed setting.
Are you using MSI Afterburner to overclock your card?
If yes what are you other readings.
I am running with a custom Fan speed profile.
Your CPU and Mboard temps look OK
Run your card at the standard settings and report your temps
Yes, I am using MSI Afterburner and Kombuster for GPU stress.
Reset to default (1010core 1375ram Vcore1049mV Power Limit +/- 0%).
After 5mins stress 80c (fan@45%) after 5mins idle 56c (fan@21%).
Using the OC profile (1125core 1500ram Vcore1174mV Power Limit +20%)
After 5 mins stress 91c (fan@57%) after 5mins idle 66c (fan@33%)
What sort of max and idle temps do you think I should be running at? I will play about with a custom fan speed profile to try and achieve them. Maybe compromise with the oc a bit too.

That looking much better with the custom fan profile, that the way to go.
Max I would want running is approx 80C, lower the better
Have you tried lowering your Vcore on the O/C?

Yes aim for 80C with 100% load is good, games will run at lower temps.
Your idle temp is higher than I would expect can you please check in MSI Afterburner to see what is your core and memory readings at idle should be dropping down?
I just notice that you are running 3 monitors that why your idle temp is higher your core and memory readings will also be higher.

Solved and thank you. Got voltage down to 1080mV and stable, put a stronger fan in side of case too. Now have 73c on oc profile under load with fan speed at 49% and 53c idle with fan speed of 33%. Dropping the voltage made biggest difference

That good news.

Still high for a 7970, which flavour do you have?
I would say that it near normal now with a good fan speed setting on 100% load for O/C 7970 with a reference cooler
Gaming will give slightly lower temps as well
