Hello Folks! It's my first time posting here...  new to solo mining and this is my first NerdQAxe++

I went to re-paste the thermal paste, which in hindsight was not needed as it was still gel like / moist. 

When tightening the contact screw for the cooler the screw broke off... I made a rudimentary fix (pictured) but would like to do a proper repair.

Questions: 

\#1. It seems the bottom bolts are replaceable (they seem to slide out of the plastic  backplate) - does anyone have any links or sources where I could find a replacement for the individual plastic slide-in bolt holder/bolts, or an entire backplate ? 

  
\#2. How about the screws for the mounting frame of the waterblock / pump combo? These look pretty standard, the model mine was shipped with is branded "Snowman" 

\#3. Now that I have to take the thing apart again, I am thinking of trying liquid metal, has anyone done any comparisons and found it worth experimenting with liquid metal on one of these rigs?

\#4. I am looking at installing the grafana / influxdb monitoring but since this is my first rodeo I would like to ask, will I be able to monitor the individual core temps? I'd like to see if the core that's near the broken screw is running hotter, but not sure if this is possible.. but if questions 1 & 2 get answered this might be a moot point.... 

If you made is this far thanks for taking the time to read & happy holidays
