I'm using Conductonaut as nt TIM for my RX580 since January. When tearing down the PC to swap cases, I thought of checking on the TIM to see how its doing.
Opening the card greeted me with this sight. the liquid metal looked completely dried up.
Closeup of the die. Rubbing on the liquid metal with my finger tip only made tiny parts fluid again ( visible in the pic)
Cooler close up. Same observations as with die, only tiny spots appeared to become liquid when rubbed with finger. It also looked like a part of liquid metal disappeared from the top? I have been running the card in vertical mount for the past month. Heatsink base is nickel plated.
Rubbing the die with acetone left behind these spots. I could pick them with my finger nails with some effort though
Rubbing the cooler surface hard with acetone and rags left behind this. I couldn't shift anything with finger nails.
Added liquid metal again and assembled the card. I probably have used way too much this time, sigh.
Temps have gone down by a degree but no major change to speak of.
My questions :
1. What happened here with the liquid metal appeared to have dried off? Is it normal behaviour?
2. Is re-pasting liquid metal after sometime necessary, if yes how often should I do it?
3. I cleaned the die thoroughly with acetone and then IPA, used the included applicator ( black q tip) to spread the liquid metal as thin as possible on both die and heatsink. Did I make any mistake, should I have done anything differently here?
4. Considering there was no difference in temperature, was it have been okay to leave it as-is?
