Re: Intel D945GCLF Bloated Samxon GC due to overheating
0.04 ohms isn't bad considering MCZ's sensitivity to heat and relatively high H2O content in the electrolytic mixture. Also, the rubber seals do degrade with age, and that too causes drying up. 0.01 ohms is pretty good, but another important question is how high the capacitance measures, because if a capacitor is going leaky or is partially shorted, it could measure in spec for ESR but would yield a capacitance reading much higher than the 20% tolerance allows for (early HMs and HNs failed exactly in this manner).
This one is harder to say. The Rubycon MCZ probably looks completely genuine if you put aside the cheapo bullseye bung? This is another reason that I'm not convinced Intel/Foxconn/Flextronics (sometimes Intel used ASUS or Pegatron as their OEM as well) sourced their components directly from the factory - they likely rely upon previously trustworthy distributors who could eventually foul up with counterfeits slipping into the supply chain amidst the genuine capacitors.
Rubycon is the most expensive brand for a reason. They have no factories in China and they important everything from Japan, so their electrolytics are pretty much built to the highest order. Either we are looking at potential counterfeits or Rubycon were specified not to use their thicker bung design for some reason.

Did Intel China knowingly use fake Rubycons, or did they also get conned by a flaky vendor? Or alternatively, did Rubycon outsource production of (some) MCZs to a volume OEM producer in China?
