"the towel trick" is NOT a good thing to do to your machine
it will cause worse problems down the road, and it's only temporary anyway
Microsoft made shitty design choices on the xbox, there are solder joints that have a lot of pressure/stress on them from the clamp used to hold on the heatsinks, the xbox gets just hot enough to stress the joints enough to crack/breakthem, causing a RRoD.
what the towel trick does is heats the xbox up to EXTREMELY HOT temps and actually remelts the solder causing the cracks to melt back into a solid solder joint, but over time it just breaks again.
the best thing to do is to just send it back to Microsoft for replacement, if that is not an option, then have someone do an x-clamp replacement, right after a towel trick
the x-clamp replacement will relieve a lot of the pressure put on the board, but then you will also need more/better cooling for your unit once fixed
the newer 360's did not fix the x-clamp issue, but what they have done is to shrink the cpu/gpu die size which makes them create a lot less heat, and they have added more heatsinks, to dissipate the heat better as well, less heat = no broken solder joints
if you continue to do the towel trick, it will fry a lot of the electrical components in the xbox and you will really be fucked then
