is 70ºC too hot for a graphic card? (broken already?) - page 2.

5 more hours mining (9 hours total no-stopping)

   Activity: 99%
   GPU clock: 1150%
   Power: 0%
   Temperature: 69º C (I assume because it's already night and the outside temperature has dropped significantly)
   Fan Speed: 85%

It seems that works pretty well Grin

let's see how it behaves in its first 24h of life Cheesy

Edit: Why is "power" 0%? What is that?

^ you should take that card apart and clean it and apply new thermal paste.

I run 4x cards per board all very close to each other and try to keep things under 80'C

i have a 6870 and mine runs at around 89 celcius when mining. fans are at about 95%+

I've been mining for 4 hours. I overclocked it and put the fans at 85% (manual mode) and got these:

    Activity: 99%
   GPU clock: 1150%
   Power: 0%
   Temperature: 72º C
   Fan Speed: 85%

For what I read, it seems pretty good if I don't reach 85º-90º C, right?

Also I got a new case, so I have more room for fans. 7 total. (not counting power supply and CPU fans)

3 fans installed on the graphic card (came with them)
2 fans at front pulling in air
1 fan at the back pulling out
1 fan on top of the case, pulling out

HODL OR DIE

I have a low end GPU from ATI in my desktop machine. Suddenly I was having problems playing quakelive with crashes as soon as I started to play. I ignored this because I assumed it was something to do with the game and gave up caring. A few months go by and I start to get stuttering with video playback on things like Netflix then VLC. So I start to investigate my GPU and find out my GPU was running at over 100C on idle! I opened the case up and cleared dust and it runs now at 50C. I am amazed it didn't brick the GPU because it was running hot for MONTHS.

92% fan(s) I'd say it's too high. Try keep your GPU fans under 80%. They'll last much longer. Anyway at 85% seems to be the point of diminishing returns.
Maybe you need to install a front fan to bring fresh air into your case toward your GPU air intake.
70 C is very decent for 1100Mhz. I'm not bothered until 80C from a reliability point of view. But it good to keep temper9ature low for at least two reasons: 1. current consumption is significantly lower; 2, overclockability is better (if you can keep your 7970 at 1125MHz at 80-85C, then probably you can reach 1150 under 70C).

remember there are multiple GPU sensors... if thermal paste or pads aren't applied correctly, you could be seeing a 65oC for the card, but gpu sensor 3 might be at 95oC. i consider it a 'good job' if they're all within 10oC of each other

what's safe for VRM temps varies quite a bit, depending on the manufacturer... but it *should* be good up to at least 105-110oC. some can run stable up to 120-130oC. i've got one card that has been running nonstop (outside of a couple brownouts and one blackout of a few hrs) w/ a VRM temp ranging from 95-105oC.. never crashed once... 5870 @ 1000/315. gpu temp ranges from 55-65, sensor 3 up to about 70oC.

oh, I run all my fans at 100%. from my experience, it wears them out quicker w/ variable speeds (i.e. slowing down as the card cools, going faster as it gets hot, etc). i've been running ~15 cards 24/7 for the last 7 or 8 months and have had to replace 4 fans (3 from reference 5870/5970, and 1 from a gigabyte with that crappy dual fan setup... i just ziptied a 120mm on that)....

and one PSU failure =p

70 FAHRENHEIT is super cool, your PC must be in a fridge.

70 CELSIUS is a good temp, especially with an OC.
70% Huh

who knows

Get GPU-Z to read your GPU's temperature sensors.

Its not recommended to mine 24/7 with fan speed at 90%+. Try to keep below 80%. The GPU fan may fail much sooner if you don't.

CGMINER is good for setting fans speeds, clock speeds, etc. It is command line app, you'll need to read up on it.

What do you recommend to not have your fans 24/7 at 90%? what do you do to cool it down?

Yeah I would be happy if my cards would stay around 70'C

Usually closer to 80'C I would start worrying if you start hitting 90'C and above

Hi

I just bought an ATI 7970 and ready to mine

Right now I got these values:

Activity: 99%
   GPU clock: 1100%
   Power: 0%
   Temperature: 70%
   Fan Speed: 92%

are these values ok? where can I get more info about temperature and OC?

Thanks! Happy Saturday
B.

Edit: Temperature: 70º C
