Topic: Litecoin overheating 95C - 100C? bad for ATI? (Read 3160 times)

Well, technically, any coin that you are mining is a GPU killer. The coin itself is not... I have some Litecoins sitting in a wallet, some Bitcoins sitting in a wallet... not actively mining THEM, but mining others.

It all depends on your mining temperature cutoffs. Yes, hot weather will increase the ambient room temperature, making the air in and around your case and card able to have that much less potential to absorb the heat generated by your mining. Air circulation will help with that, but you also need to have an input of fresh air and more importantly an outlet of hot air for the room.

You are responsible, however, for setting the proper temperature cutoffs for your card. You're essentially telling it to process as hard as it can until you tell it otherwise, and to dump the excess heat in the vicinity directly surrounding your card. When that vicinity can't absorb more heat... your card itself can't dump the heat off, and retains heat. YOU need to set responsible temperature throttles and cutoffs for your card, so it will cut its hashrate until its down to a safe temperature, or flat out shut off if it hits an unsafe level. If you don't set temperature cutoffs, and you don't ventilate your location, you have a recipe for destroying a piece of hardware that will cost you months of mining on it to recoup the value spent on a replacement.

Garbage in, Garbage Out.

same problem here

Same problem, minus the shipping container. Mine are in the loft which is heating up just as much. Typical that I'm not even in the country to enjoy the weather when it finally sorts itself out for a few weeks!

I've got CGwatcher installed on my rigs and its set to automatically throttle down the intensity during the day to hold the cards ~80 degrees. Then it ramps it back up during the night to full speed when it cools down a bit. Losing a bit of potential output, but its the best solution I think, to reduce the risk of setting my house on fire more than anything else..

That's one hot oven

i got mine to 500 C , i threw it in an oven

First of all - technically graphic cards can work up to 115 degrees (celsius) yes, it is over magic 100 number.

Ask any manufacturer they will say - it is fine.

Problem - none of them have tested what will happen if you run your card for weeks at that temperature


And with any electronics cosmic law is - lower temperature = works faster, and will live for much longer.



We have hot summer too, but here is what I have:

gaming case with 3 coolers and proper airflow, HD6870 with 2 coolers on it

when I pushed mining settings to best I can it was running 85 degrees with coolers working 100%


.... then I opened case and cleaned everything, especially my card and it's two coolers


Now it runs 79 degrees with coolers on 60%
or < 60 degrees with coolers on 85%


Point is - if you want to make load on your card and pc constantly:
1) clean it often
2) get proper case with proper ventilation and coolers

my opinion - there is never too much coolers (I am adding 2 more high pressure intake coolers on my case soon)

Your GPU's might last a long time at 95. Statistically, they are much more likely to die than if they were running at 75. My advice would be to play with the engine and memclock config at lower values until your card runs cooler, and turn them up again as the weather cools.

Back in the early days of BTC mining, a friend and I had a 6870 that I found at a yardsale for like $20. I had it mining for pretty much two years straight. At 100- 105C. It was cheap so I didn't care, and took over 2 years to die and I dont know how much use was on it before I bought it. But, I still don't reccomend doing that, had the card not been cheap to the point of not caring, I would have been worried about it dying.

I'd try and run your GPU's cooler, 76C is acknowledged as target temp.

Add big fans, think box fans, that's way too hot. Heat is a killer, cooling is the key.
6950's@72 18 I  (2 in a box)
7950's@73 19 I  (4 in a box)
7970's@71 19 I  (3 in a box)
I used the hottest value for each box.

As much airflow as possible helps. 95 is hot, but I think the GPU should be OK. Its the fans running at 100% that tend to go first.

LITECOIN is a GPU killer
my gpus are overheating in shipping container, 95C on average, alas we have a hot summer in London UK outside 30C
will my gpus last?
they are 6970s and 7950s
what is your experience with temperatures?
I am not sure if it was hot temp that killed one of my 6970 HIS or was it intensity 18.
what do you recon?
