Overheat of Graphics hard with RavenCoin

[oskoa]

Ive this problem with this miner, nbminer.

When i use Claymore to minining Etherum i dont have problems (Stable temps below of 75ºC, until 67ºC in cold days).
But with nbminer and RavenCoin my cards feels a big high change (about 20%), one card touched the 90ºC, and the rest until up 80º- 85º.
Have I  any option in nbminer parameters in Bat file to avoid this? Also i see the problem is with 4 GB Cards.

I have the following hardware cofig:

Only 1 PC with 1 Card (my Main pc, only use to mining in free time) With RX 570 8 GB Asrock (no problems with this card)

and in my Main Miner i have 5 cards (the main the same of before but in Asus) and the rest are:
x2 Radeon RX 470 (Sapphire x 4 GB)
x2 Radeon RX 570 (MSI x 4 GB)
Powersuply: Seasonic 850W

The only cards without problems are the 8 GB

Exist other minner for RavenCoin, or anyconfig to avoid this problem?

You need to clean those fans of the cards from dust and undervoltage it a lot if you want to keep temperatures like it was on eth. RVN uses 20% more watts.

KAPOW algo utilizes the GPU more heavily than ETH so you can expect a much greater temperature.  Your best bet is to undervolt and lower the GPU core speed if you need to stay within a certain temperature.

You can add some auxiliary coolers, it works very well:



I usually use auxiliary coolers when the ambient temperature exceeds 30 degrees Celsius... Reduces the operating temperature and increases the durability of the gpu coolers.

wow very thanks to all!. Really was it. I only made an underclock (less clock/memory) and the temp has down until 75-70º in all cards.
And yes o i have 2 80x80 coolers in diferents sectors.
Thanks again.

the last question, RavenCoin maybe will be the new "etherum" in case Etherum in November 2020 stop beingin profitable?
