4. Heat sinks added to RAM/other chips
Don't call me crazy because a lot of people recommend this and this surely is useful. I checked after a few hours of playing Xbox 360, the said heat sinks were heated up, good sign, the chips below will be cooler resulting overall cool Xbox 360 - yeah I know the heat these tiny chips generate is not comparable to the giant CPU/GPU but even a degree counts for me.
Oh, 4 of these tiny heat sinks are available for SALE. Will make a topic for selling it later.
5. Lapped GPU/CPU heat sinks
As if the thermal compound mess M$ did was not enough. The heat sinks were in a very bad condition. I was not thinking to lap the heat sinks but once I saw them, I decided to lap, quick searches on Google, few shops' visit and I got the right material for it. I was in a hurry so did a quick job, before looking at the pictures below, please don't dis-heart me : p. I don't feel like taking Xbox 360 apart for lapping again since I injured two of my fingers in the process and got a little jhirak from mother as a result of it.
The lapping result was good, better surface at least than what M$ left if not a quality mirror-like smooth surface.

6. Air Tunnel/Heat sinks upgrade
A guy named
RBJ came up with this. He has measured temperatures in complete details. Go to his page to see all of his work. So anyway, Xbox 360's fans do not suck air fully from the GPU heat sink, which is the most problematic heat wise. So what he basically did was to divide the air tunnel so each fan sucks air through each heat sink and he put a plastic/card board piece on top of GPU heat sink so it actually pulls air from front through complete GPU heat sink.
I did all that plus as he recommends and others have done the same too, tape those areas you see properly so there is no suction/air loss. Before bashing me for doing this, please do your research then come and reply : p and no the tape won't melt, it does not get THAT hot there.
