3 penny fix (for me it was a two penny fix with existing termal pad cut'em in 1/4) worked for me. I bought couple of 3RODed x360 from ebay and were going to replace xclamp with other tutorial posted here. Decided to do penny fix since experiment requires a lot shorter time and minimal hw.
First, did a wiki search for pennies manufactured with most copper. (est 1970 - 1980, contains 95% copper, 5% zinc). Cleaned it with running water and tooth brush&paste.
Second, opened x360 up, took termal pad off, cut'em to 4 pieces. took cloth backing off, set it back on memory.
Third, stacked two pennies with a bit of AS5 in between, wrapped it with aluminum tape (cut'em 1/4 inch wide 1.5 inch long)used for HVAC sealing/wrapping.
Forth, set stacked pennies on top of memory, put bottom metal casing backon, put black screws for heat sinks back in, and re connect dvdrom,power, av cable. Leave fan disconnected.
fifth, turn x360 on. 3ROD. waited about 10 minutes. turned off for 2 minutes. plug fan connector to mobo. turn it on. 2ROD.(over heat) GREAT!
Sixth, powercycle (turn off, back on) and volia! got x360 dashboard!
Left x360 with GOW running for 2 days in a garage (Avg day time temp is around 95F. temp drops to around 80F in the evening). No sigh of 3ROD. Last night, played for about an hour before turning it off. Today morning, before heading for work, I turned of x360 and everything is fine and dandy. Left it running. Will findout if I get 3ROD or not tonight.
Thanks Y'all!
