Title: Antminer v1.6 fans not rotating Post by: danyst on January 31, 2014, 09:28:11 AM Hello all,
I'm wondering if others have this problem also. I received last week 3 antminers S1 v1.6 and they all seem to have the same problem. When we connect them with our PSU via 2 PCI connectors the fans don't start rotating. It looks like they want to start, but they don't. For the moment we connected the fans directly to the PSU and now they are rotating in full force, which makes a lot of noise off course. We didn't have these problems with the v1.4 which we have also currently running.

Kr, D They are later versions of the fans, they do not start turning until the miner starts hashing and the chips warm up.

The fan starts turning after 2 minutes, when the blades get warm enough.

It seems like the new fans have a different starting voltage then before, so wont trrigger until the PWM feeds a certain amount of power to it. |
