As was the case with the Ultra-120, the eXtreme requires motherboard removal for installation of a custom back plate and new S775 mounting bracket, the design has slightly changed to allow it to pass between the heat pipes.
The heatsink is secured with 4 screws and can be left installed when transporting your system. We had no clearance issues around the CPU socket as the bracket is quite compact and the eXtreme fins leave clearance for fancy northbridge cooling solutions.
Before we install the fan you have to stick these two anti-vibration strips here:
We advise to install the fan on the heatsink before you reinstall the motherboard inside the case, especially if you have a smaller case, access to the fan clip can be near impossible.
Note that in the photo above we have modified the GlobalWin NCB fan to allow the standard clips to be used, “rib” type fans are not support by the Thermalright clips, only “Flange” type.
This allows installation of 120x120x25mm and the larger 120x120x38mm fans with one set up clips, but if you have a “rib” type fan, you’ll to improvise.
Onto the performance tests ->
