That looks good. Yeah I was concerned that whatever process was occurring between Liquid Ultra and the copper would cause it to lose its fluidity and lose contact in the relatively near future.

Cleaning the stuff off the heatsink is a PITA though. The abrasive pad approach is nonsense because it messes up heatsink flatness. You really need to lap the heatsink if you plan to use regular paste again.

I have two desktops with Liquid Ultra. Can't resist delidding Intel CPUs for that 20C drop every time. The IHS has nickel plating though which is resistant to most things.

 

Clean off the surface and use paste again, it really should not matter being discoloured.

 

Anyone have a recommendation for a reputable place to buy a replacement CMOS battery? I found this on Amazon. Has the same part number and the same connector as far as I can tell from the pictures. But there are a few reviews that say the batteries arrived dead.

 

You don't need those. Get compatible Duracell or Energizer button cell battery and replace. Then use tape to cover the battery.

I haven’t torn the black covering off the old battery. How is the connector wire attached to the battery? I guess I had assume that wire wasn’t swappable to a new battery.

 

It's not soldered. Worse case just attach bare wire and use tape to stick them to the battery. It's just "fix it and forget it" item anyway.

Tape the bare wires to the battery? Hardly sounds very reliable. Pass
