Hi,
I have had my MX 2 for about 10 days and have had a chance to play about with it quite a bit.
I first flash finless 1.5 which seems pretty nice. I then had issues with the wifi since my router is upstairs on the other side of the house. So i cut an antenna off an old router and soldered that on which works pretty well (from almost no signal to 100ish Mbps)
Finally i had a few issues with the box hanging for a few seconds at al time so i took it apart again to have a look at the cooling setup. On the MX2 its pretty dredful anyway. I thin small peice of flat aluminium stuck to the issues of the plastic case and a thick thermal pad to touch the SOC. After looking at mine even this very poor heatsink setup had been made even worse by the fact the thermal pad had been missplaced in the factory an wasnt even touching the cpu. If was actually covering the two ram chips. My guess is this was causing the SOC to over heat and then thermally throttle. I decide to take drastic action so i took a pretty big old ram sink from an old Quadro graphics card, lapped it and then epoxy´d it straight to the SOC. The cure time was shortened by sitting it on a radiator. This also makes the epoxy set much stronger when it has set and thins it a lot while curing which allows to to get a much thinner layer between heasink and chip.
Anyway now after testing it does seem to run smoother than before and the heatsink seems to be doign a pretty good job. I really think that getting good ventilation to the heatsink and dumping the awful chewing gum interface materal will allow the chip to run much coller than before. I also think the basic design of the MX2 is bloody terrible sinceit has the worst heatsink i have ever seem. Without the mods and even if assemble correctly which mine wasnt this model has truely terrible thermal design.
