Thanks Cherry, added it.
LEDSchlucker said:Facts:
- Overheating pauses (Mostly happens in warmer surroundings at Discharge current >700mA)
- About 10% higher capacity readings, caused by the Overheating pauses and high connection resistance
- Inaccurate (useless) IR (Internal Resistance) readings (for accurate readings, a four wire IR tester is needed)

The readings may not be the best precise but far away from "useless".Inaccurate (useless) IR (Internal Resistance) readings
I've sprayed wd-40 on my OPUS fans - no difference. Maybe buy some fans and you might get some that are more silent than others... its likely a hit-or-miss kind of thingMy main concern is about fan noise. I know there are some suggested mods but I ask, an original replacement fan will be more silent maybe because of improvements design? If I don't wanto to do any fan mod because I use this charger occasionally, will be enough to silent a bit the fan to use a sylicon oil in spray? Thank you for any tips about my questions.
