Q：Hello,
My Avalon A1246 always drop in hashrate when my immersion cooling bath reachs ~40°C to 44°C. I removed the fan but I am not using fan spoofers. Also, I did not removed PSU small fans. Do you think this is due to not using fan spoofers
A：Hi, thank you for your trust. Regarding this issue, the hash rate drop of Avalon A1246 may be caused by not using a fan simulator. You can try to install a simulator. If the hash rate is still abnormal, you can consult our technician via WhatsApp (+8619123969124) or Email ([email protected]), and he will give you a detailed answer.
