If you don't mind me asking what are you current temps and are they so excessive you feel you need to do that or is it just too loud for your taste? Is it a reference blower (Seeing how its got 950 base clock) and is it just to loud for you? Just curiosity speaking here...Heyo,
I have a factory overclocked HD7970, running at 950MHz core (or 1GHz in the 2nd BIOS). I want to lower my temps, so I will be experimenting with underclocking. I'll be posting my results here.
Feel free to chime in if you have any tips or knowledge.
Oh ok that makes since, I don't know which case you have but maybe if you can force airflow to the back with a small fan addition you could get that extra hot air out of the computer.It's this card, and in particular it's in my HTPC. It's one of the quietest and best coolers. I've currently got all fans (except GPU) set to slowest speed, which makes the GPU run around 80C at 80% speed, and the CPU got up to 90C apparently...
But, that was with terrible airflow around the case, terrible fan speeds, and no A/C turned on at the time. Also a problem is that GPU dumps heat inside the case.
This weekend I'll have time to do some more testing. I'll ramp up the base fan speeds to get more airflow going, check it with A/C turned on, and turn on fan increase for CPU as temp rises. I'll try it with stock 7970 clocks, and if it's still too much I'll have to dial it down... After all, it's running 1920x1080 so it's plenty of GPU power.
Edit: Yes, I realise how utterly stupid it is to use a 7970GHz that dumps heat inside this case when it's shoved into a TV stand.
If you reduce the clock speed, it won't need 100% power. Just figure the percentage of clock speed reduced and reduce the power almost the same percentage. This should further reduce the temps since you're not feeding it power it doesn't need.I have this card.
I thought reducing power% can lead to instability since the card may be starved of power?
