Title: 5970 Wants to run at 90 C, Is this to high??

I won't try to run at such high temperatures, maybe 70+ will be better for your cards to live longer.

Hi,

I picked up a 5970 for a good price as it has a few lines through the video, but I dont care much for that as Ill be using it for mining.   Seeing as these have 2 GPUs I am not sure if what I am getting is to high.

Essentially, it wants to run at between 89 and 91 degrees C.   Should I be overly concerned?  Or do others find theirs run at this temperature?   I have it housed in an open air box in a cooled server room.

Thanks for your opinions.



How about repasting it with a better thermal paste (i.e. ICD 7)?

The VRM will overheat and melt long before the GPU core will.  I've lost a 5870 due to this - it's well documented on this board.

Nope, i run mine at 100c and it loves it!  no reboot for two weeks now and it's been active for 3 months.

i never ran mine above 80oC, but im sure theyre perfectly fine up to 90oC or so

for 6-12 months maybe

they throttle themselves when they reach 100oC

re: VRM temps, yeah, i didnt care about that unless it went above 100oC.  anything below 115-120 should be ok

5970's tend to run hot anyways since you have 2 GPU's on board. Unless you're running 100% fan, expect high temperatures.

Normally it should be 70 oC

Normally it should be 70 oC

With auto fan, stock volts, stock speeds, the 5970's that I test for 3d stability tend to level out to about 95C per core and 100-110C for VRM chips. In a well ventilated basement with proper exhausting, my 5970's get 65-70C at 100% fan WHILE UNDERVOLTED.

Yes, these get hot. Just deal with it.

mine is oc'd to 850core n 825core mem @ 300 and is only at 70c with 80% fan...so 90c @ stock i'd be worried...unless you have it sandwiched (a card below it blocking air flow)

well its really upto you whether or not you want to run the card hot...some ppl say they ran cards 100c+ for months on end w/o any problems...some try that and the card burns out...i dunno...but since the diff rate change all my miners just got shut off :( no more btc for me..Good Luck to you :)

also keep in mind one of the GPU's VRM banks run amazingly hot compared to the other. Between 10-20c hotter. Use gpu-z to verify temps.

90C° is normal temp for 5970, I had few of these cards, they were running all the time and I even saw more than 95C°, if you set fan manually at 85% you should get the temps lower to 75-80 C° but you will reduce the life time of your fans.

Fans are about $15 to replace. 5970 themselves cannot be replaced if they burn up. They aren't made anymore.

all what i wanted to say that he can config his cards to meet both life time of fans and cards, in my case 90C° is not that high given the fact that he might see even higher when summer goes crazy

Thanks everyone,

From the sounds of it, as I suspected, the general feeling is that they run hot anyways due to the dual GPU point.   I will let it plug away at 90 C.   Not so worried about the card burning out as I got it cheap, just didnt want to start a fire or anything.

Thanks...

Mine max out at around 75oC w/ ambient temps from 100-110oF in the afternoon.  You should be able to manage that even with them at 1.05v, just dont use a case and have a honeywell fan.

I LoL at the crap in overclocking forums, but, seriously, I wouldn't want to be running a card at 90oC 24hrs a day.  80-85o would be ok.

did you buy it used?  it probably has a crap thermal paste job... or thermal paste from like 3 yrs ago
