    Just clean it as good you can. Won't make the big difference for the cooling. You can if you want sand it carefully with 2000/3000 grit sandpaper. The best working cleaner... http://www.performance-pcs.com/indigo-xtreme-clean.html

    Jesus Christ......if i knew this i wouldn´t put it in the first place........look to the Thermal Grizzly email reply "acetone should help to clean most of the liquid metal. If you want to RMA a CPU and can't read searial number or batch anymore it can help to use a 10% solution of hydrochloric acid and swipe your CPU several times. Be careful though doing that and wear the approriate safety gear such as goggles and gloves." .... I´m not a chemist....isn´t there any other way of taking this out without scratching the surface? i saw this vídeo could this help? is this compound similar to the one used to take out scratches from cars?

    Unfortunately it does not work. I have made such settings. Maybe my bios is broken (Version: 1.05.04TDES, KBC.EC: 1.05.03, ME 11.8.50.3399)
    Maybe I need to upload older bios?

    When I highlight "power limit 1", description appears on right side and it says that "Value must be between Max and Min Power Limits". It does not make sense to me

    Ok.......finally i have a solution......i used the polish method, i can tell you that the copper looks like a mirror now, after a couple of hours i clean it all, give me a lot of work........now let´s go for the CPU.........i only made a last clean with isopropyl alcohol just to be sure that even the polish that i used is cleaned also on the copper cooler..........but i can assure you that the "polish" method works.....

    Yeah, stock BIOS has a hardcoded limiter which seems to be in 95W region for your CPU model while it is 118W for its bigger brother. OCCT put's an unusual high load on the CPU, so it hits it early on. In RL usage you should be able to maintain higher clocks...

    It varies from sample to sample down to exact fit of the cooler and the chip along with the calibration of the internal sensors.

    I know, but I'm looking for a rough figure I can use as a benchmark.

    A perfect application and delid should lower temps by around 20C on the CPU.
