  • Locate the Cooling Unit on the Apple G5.

  • Put the CPU case on its back with the opening facing up to make the next steps easier.

Adım 2  ¶ 

Unscrew 8 T10 screws from the cooling unit. NOTE: these screws are acctually allen keys. The prefered tool will be long handled allen keys. t10 are 2.74mm (closest allen key is 2.5 or 3mm) and t15 are 3.27mm(closest allen key is 3mm and 4mm). You may strip your tool or the actual screws themselves. Use a set of high quality long handled allen keys. The screws are somewhat hidden, so they cannot be see in the picture. To visualize the location of the screws look 3 steps ahead.
