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.
