Both the SLK800 and SLK600 come in the same type packaging as you saw in the previous page. This of course helps to protect the heatsinks and their thin fins. What you get in the box is the heatsink, clips for mounting a fan, white thermal grease, thermal pad and foam spacers. Why include spacers? There is a good reason which we'll get to shortly. Below on the left are the items that come with the SLK600 while the SLK800 items are on the right.

Above you can see how narrow the bottom heatplate is and how narrow the whole SLK800 heatink is for that matter. The SLK600 has the same basic design though with less overall copper and denseness (75g less to be exact). Great thing about having a narrow heatplate as the 800 and 600 both have is it allows airflow to the cpu area while the heatplate still covers the actual small raised cpu. Plus since a fan overhangs both heatsinks (if you use an 80mm fan on the slk600), the extra airflow helps to cool surrounding components like the ram and chipset.

The picture below on the left of the SLK600 bottom demonstrates how both heatsinks look with the pads installed, on the right shows where the heatsink touches the cpu if it is installed correctly*. They should be installed because since the heatplate on both heatsinks are so narrow, they do not fit over the cpu rubber spacers. The included spacers apply very simply and do help to prevent a crushed cpu core. Just peel off the backing and stick them on as pictured.

Installation~

*Be sure to try several flathead screwdrivers on the front heatsink clip first and choose one that fits the slot best so it doesn't slip out, but gives you good control over the clip. Thermalright suggests to install the heatsink first, then the fan. I do not suggest that because doing so could move the heavy heatink on that tender cpu core and possibly cause a cracked core if too much pressure is applied on one side. Plus with the heatsink not yet installed you can be sure the fan is attached securely and have the fan clips in the best suited holes on the side.

First attach the fan using the supplied fan clips, then connect the rear heatsink clip over the rear motherboard catches at an angle, but not so it is hitting the raised cpu core. Then gently lower the heatsink evenly on the cpu. While keeping one finger on that rear clip to keep it in place, attach the front clip to the motherboard using a flathead screwdriver, insert it in the slot on the front clip and carefully guide the clip over the front 3 catches. Some force is necessary so go slowly. Both heatsinks use a 3 prong clip (major kudos!) and install very easily with a proper fitting screwdriver.

<-Wrong | Correct->

*Shown below is the heatsink attached to the front, where the screwdriver slot is.

*Be sure heatsink is as above

*Since both of the heatsinks are narrow you must be sure after attaching the clip to the rear that the heatsink is mostly towards the back and NOT the front. If too far towards the front I've found the heatsink will overhang slightly on the plastic part just behind the motherboard catches, thus not contacting the cpu as it should. I did this initially and once I figured it out I reinstalled the heatsink with it mostly towards the rear and temps dropped 10-14 degrees.
