Also, if you will lower the frequency, i would suggest detaching the external fan. If you lower the frequency, the power usage also lowers and the boards radiate less heat. This is however something i would recommend doing during lower temperatures and not in the middle of the summer... although the miners we are not selling are doing just fine with this "hack".

I'm interssting with this, Whats is the  lower frequency you run.

Thanks

I buy two pieces on Ebay , i think it's you sell IT.

I found in the miner some fan parts, a connector cut from a Fan , in the two pieces , when you move it your heard moving.

Some cards have  missing plastic retention for the radiator , small white pieces to  maintain radiator to the PCB , i found in the miner this piece , i  need to remove it before start the miner.

I resume , fan conncector and plastic retention in the miner, need to remove it before start miner.

The miner dont go far 400 mhs , i use antminer L3+ and a Innosillicon , in the same environnement, run about 600 - 640 Mhs /second , with fan at 60%

The firmware is 2.8.0 and dont show the temperature of the PCB.
