MSI Says My Overheating 7970 Lightning is Normal!!! - Page 8

post #71 of 148
LOL...I just wanted input from the AMD rep about normal temp ranges for the 7950. Anyway I did change the tim with some noctua NT-H1. Idle was around 38C, and load dropped to 71-72C...so about 5-6C drop. Not bad for 10 minutes. Need to check an overclock run and see the difference there still.

Edit: Ok just ran a load test at 1000/1400 with stock voltage. Temps maxed at 74-75C with fans around 60%. Much better than the low 80s I was getting before.

7950 and 7970 have the same thermal threshold. I have five reference 7970s sitting here, and all of them go to 80-85C at load in a well-ventilated 650D.

I've been using mx4 for air & water cool TIM lately, it's pretty good.

As stated before, I usually reapply TIM to my CPU & GPU on an annual basis. The TIM I use is MX-4 as well. I didn't know that the manufacturer's TIM was about the same as what's readily available. I always thought they used some high quality TIM like the Shin Etsu. I guess going forward, I will reapply TIM from the initial run of the GPU and then update on an annual basis.

In any case, thank you to all for your input and information and I hope that others have benefited from this thread as well.

With what fan speed? For 30% I would say that is good. For 100%, not good.

Automatic/BIOS-controlled fan speed. I never bother with custom profiles.

So from what I have seen, that would be about 30%.

 

Which is good.

I have contacted them and all they say is that the rest of my system is making the card heat up due to poor ventilation ... .. I use a Raven 02-e ... Poor ventilation my *** ... lol ...


I am looking at water cooling seems that local vendors won't help and MSI doesn't reach out of the US ... which I don't understand ... but thanks for the reply anyway ...

Kind Regards.

There is nothing abnormal about an 80-95C board, particularly if the case is not well-ventilated.
Very sorry to hijack thread, but i am interested do you have info for HD 7870 ASIC max temp.
I am getting two of them, so i need some info.
Thanks in advance.

MSI binned the Lightning GPUs for low ASIC quality, to perform better under extreme cold. The trade-off is that these leaky chips run much hotter under air/water cooling.

Check ASIC quality yourself with GPU-Z.
