I tear down the whole loop several days ago. I disconnect the Molex to power the Aquaero. I started to fill the loop using my power supply.
The moment I switched on the power supply with just the pumps connected, I can smell some smoke coming from the back of the case. Upon checking, its the Molex to SATA wire that I did use to power the Aquaero.
The molex wire to sata was puchased from Ebay several years ago. The copper wire was so thin and it had only few copper and it melted.
I plug the the Aquaero directly to power supply molex and both pumps and the Aquaero are working now and everything is back to normal.
Lesson learned is never use a molex to sata adapter to power the Aquaero.
BTW is there a way I can make a request to Aquacomputer if they can sell concentrated Double protect Ultra to make a liter of coolant? because the cost of freight to ship the 1 liter to my country is more than the cost of coolant itself. I am willing to shell out 10 euros for a 100ml small bottle. Maybe Aquacomputer should look into this.
Lesson learned indeed! Thankfully you got away without damage. Bneg from the Overclock.net forums tells the story of cheap cables that killed most of one his systems I believe and almost started a fire.
A couple dollars more is worth it in the long run but it is always easy to assume a cable is a cable so paying more is a waste. Not all cables are equal of any kind.
I have seen some real dangerous ones in my time, especially from Ebay / China specials
