ok so because i believe in sharing info with others especially with mining hardware makers that take little to no time to help users out after they fork out thousands and thousands of dollars i have decided to post some info here for the community and hope it helps some people out.

First let me say thank you for the information you provided. Now all we need is someone who wants to be helpful and go through this thread and condense it all into a wiki or pdf thing or whatever so that you dont have to search the entire thread Cheesy

Problem #3 - the psu's ran pretty hot. this annoyed me even though they run fine. to resolve this i did a couple of things. first i opened the psu's up to see which was the fan was facing. i found out my psu's sucked air in from the back instead of blowing air out of the back which i would have expected it to do.

Yes it is stupid that they got the "RA" model instead of the "NA" model. I believe it is entirely the only reason for that heat shield on the back as well. The part number the R/N means reverse or normal airflow. This is kinda important for those replacing to know, I have seen a lot on ebay claiming to be cointerra compatible and "N". If you run 1 "N" and one "R" the heat will circulate through the two PSUs and they will get much hotter than normal.

so to get to step 2 i had to swap the airflow 180 degrees. to do this i remove the fan and pushed the 4 rubber holders through the mounting holes so it could be taken off of the plastic mounting plate (sounds confusing but if you look at it you will see what im talking about). once removed i flipped the fan around making sure to keep the fan cable facing the same way and pulled the rubber mounting legs through the fan holes to lock it back to the plastic mounting plate.

I was curious in a previous post if this would actually help and if that was the only thing that needed to be done. Was the screw a T5? I didnt have anything small enough so I never fully took the cover off and could not get to the fan without doing that.
