Now.. you have 3 options
1. Send your 360 in to Microsoft ( The best option under warranty)
Assuming you have no warranty / have already opened the 360...
2.Try the Penny Fix
3. Read this instructable!!
Step 1: Parts
The rest of the instructable we will be working with the 16 mm and soon I will post one using the 10mm bolts
My Parts List:
8) 16mm m5 machine bolts/ screws
24-32) 5mm flat washers, steel
16) #10 flat washers, nylon
10 tube of heatsink paste
1) bottle of Everclear or 2 step Articlean
13/64 Drill Bit
screwdriver (one that matches the head of the m5 bolts. I have flat headed ones)
small (really small) flat headed screw driver
1/4 nut driver or pliers
Step 2: Open the 360 and Remove All Screws
Step 3: Up and Out!
Step 4: Drill Out the Case
Drill out the holes in blue
remember to clean out the filings / deburr the case
Step 5: Remove the Clamps
Step 6: Remove Heatsinks
remember cpu is the tall heatsink that covers a single die while the gpu heatsink is flat and covers a large die and a small one.
use the nut driver or pliers to remove the studs from the underside of the heatsink
Step 7: Insert Screws
Step 8: Ring Toss Anyone?
Do this for all 8 bolts.
Be warned the nylon washer are a pain to get on the bolts
Be warned 2.0 the position of the nylon washers is crucial to preventing shorting( I tried without them and my xbox wouldn't turn on until I added the nylon washers.)
Step 9: New Thermal Paste
apply a small amount of new paste ( a grain of rice)
Step 10: Put 2 and 2 Together...
Step 11: More Washers!!
try both washer combos, each box is different, so the spacing is different. If you get the 2 red lights almost immediately, try the other config.
Step 12: Put the Heatsinks Back On
Step 13: Tighten, Slowly...
Step 14: Baking Time!!
reconnect the dvd drive and put it back in its spot. Reconnect the fans but don't put them back in. DO NOT PUT THE SHROUD BACK. Now balance the fans like in the second picture and turn on the 360.
you should get the 3 red lights. some might get a working 360 because the pressure was enough tor reconnect the gpu, but overheat it any way.
Leave it for 10-15 minutes (make sure there are 3 red lights not two) then turn it off and let it cool (another 10 minutes)
Step 15: Pray
