There are three retention kits for different socket types. Before installation you have to attach the corresponding retention plate to the base of the cooler with four enclosed screws:
Everything here is simple and evident, so there is really no need to go into details. However, I have to complain about the missing LGA1366 retention (that is also available for purchase separately) and about the unreliable LGA775 retention mechanism that will not prevent the PCB from bending.
The cooler is very compact at the base. The distance from the mainboard surface to the lowest heatsink plate measures 40mm, so it will easily fit even on those mainboards that have a lot of heatsinks around the processor socket:
Although you normally don’t have to remove the mainboard from the system case to install a cooler with “push-pin” retention, it is not going to work for Scythe Kama Angle. The reason is fairly simple: the plastic tops of three pins out of four are located right beneath the heatsink, so it is pretty difficult to really push them in hard. And if you need to take the cooler off, it is absolutely impossible to turn and take them out when the mainboard is inside the case. So, it’s better to install this cooler when the mainboard is out of the system case.
This is what Scythe Kama Angle looks like inside the Ascot 6AR2-B system case:
This positioning seems to be most suitable for this cooler, because the 120-mm fan on the case rear panel and the 140-mm fan in the system power supply unit will help remove the hot air outside the case. I would also like to draw your attention to the fact that the cooler fan turned out 7mm taller than the top heatsink plate, because it hit against the chipset heatsink on one side and against the first memory DIMM – on the other. As a result, we lost quite a bit of the airflow at the top, which you could easily feel with your hand stretched out over that area. Maybe Scythe and Quiet PC engineers had to install the fan about 5mm deeper into the heatsink and use a simple shroud to cover the top heatsink triangle? These simple measures could make this cooler more compact and ensure more efficient distribution of the airflow.
In conclusion I have to mention that the new Scythe Kama Angle cooler is priced at $44 and is already available in retail.
