RROD after opening system
What's up people?
I recently opened my 360 (getting ready to flash it) and put it back together exactly how it was. I didn't unplug any wires or anything, AND was pretty gentle while opening the system. I work on computers every now and then so I have the basic idea on what not to do.
Well, this was a little over a week ago. I bought me a connectivity kit online, which im still waiting on, so I didn't have to try to flash it w/o "proper" hardware. I've even started the system up and browsed around xbox live after I did all of this.
Well, yesterday I tried to browse around LIVE again, and was successful until the system froze up. I restarted it and BAM, RROD. I was able to take the casing off the system and get the system going for a minute or 2, then I got a loud beep, and the RROD again.
Now, researching the problem, it's probably the X-Clamps overheating. But it's real funny that all of this happened right after I had taken the system apart. In the past day, ive taken it apart and put it back together a couple of times, and can't get past the problem. On the (what I think is a 'heatsink', but we'll call

"Big Silver Block above one of the 'X's", there's that brown liquid stuff (even looks like drops of it on top of the bar that wraps in the "Big Silver Block above one of the 'X's" (are ya with me?).
I just ordered a set on ebay that helps me replace the X-Clamps...but Im thinking it may be another problem (again, since it coincidentally started happening after I had the system open). I can turn the system on (w/o the shell on it), and the "heatsink" gets pretty warm pretty quick, which would be a sign of overheating..but I don't know how warm it's supposed to normally be.
I've tightened all the casing screws as tight as possible when putting back together, and made sure everything is hooked up. Does this sound like it IS my 360 overheating (by some dumb chance), or did I f'k something up when I was assembling/disassembling the 360? any help is greatly appreciated!
UPDATE: I have the 0102 Error Code (check
