Pictures, and a few words about a giga-quad, crazy-cool, big typhoon duo - Page 3

Ensuring close contact between backplate and surface of the Crazy Cool heatsink

21. To fix the gap, a piece of the Mylar was removed from where the Nylon stand-off meets the Mylar shim. Score a line across the Mylar as depicted. No need to go right through.

22. Lift the edge until it snaps.

23. Mylar removed.

24. '...rinse & repeat', until all four connection points are clear.

25. Insert bolts and thread Nylon stand-offs. Tighten as much as possible. They need to be quite compressed to get the 'snugness' sought. The spanner will slip on the Nylon nut before long.

NOTE: I need to source replacement bolts as the stupid round-head bolts protrude sufficiently to scrap/scratch the motherboard tray - potential motherboard short circuit! Look for countersunk M3 x 35mm bolts. I would try to get 40mm and 45mm bolts to try too, as this would make threading the final nuts easier. See later. (Also rectified by relief holes behind bolt heads.)

M4 bolts would fit too, by the way. At least, according to the holes. Obviously you would need M4 nuts and standoffs too. Not sure standoffs are available for an M4 bolt. My local store electronics store didn't have any.

26. Insert the back-plate assembly and tighten the standoffs on top of the motherboard. Note the amount of compression in the Nylon standoff. Snug remember. This amount of compression could only be achieved by tightening the metal standoffs on top.

TIP: Sand or cut the Nylon standoff down to size (0.5-1mm?) to relieve the amount of compression.

Note, take care to keep the bolts square to the motherboard while tightening. The back-plate here is actually a little skewed. Not a big deal but it does make inserting the TTBT over the bolts a little harder.

27. Snug (not a good verifying camera angle, but see next for further evidence).

28. Paper test again. Snug! 29. Snug! 30. Snug!
