Tools and Supply:
Clear Silicone
Metal foil tape
Needlenose pliers
Wire Nuts

We purchase two ThreeLeaf T102 - Laptop Cooling Pad for $12.99 each and one lasted one day, and the other lasted two months. The weak part of the fan was its power cable which could easily be yanked out of the fan. 

This post shows the four steps to secure the cooling fan power cable and close the top of the unit.

Step 1: Fig.1 above is the TreeLeaf Logo. Fig.2 below shows that the first steps was to secure the wire nuts to the plastic case using white silicone caulking. The caulking is white but will be clear when it dries.

Step 2: Fig.3 shows the wiring from each fan was caulked with silicone to make sure they do not move.

Step 3: Fig.4 shows that even though the wire nuts and the fan wiring was caulked with silicone. The lead wire was additionally caulked to the plastic case. Notice the white on the back of the case.

Step 4: Fig.5 shows another layer of protection was added to make sure the power lead wire would not be pulled off the case. Fig.6 shows the power was checked prior to assembly. Fig.7 shows the cooling fan was working and powered from the HP laptop. Use needlenose pliers to straighten all the metal tabs, and place the grill into the plastic case. Now, use the flat tip screwdriver to bed down the metal tabs and this will secure the unit for use. This end these cooling repair post.
