just bought a slk-800 heatsink question hows the install pretty easy, will it crack the core of my new amd cpu? or should i buy a shim? i I geuss i ask becuase my current heatsink is HCC- 001 and it a non core cracker dream

ps it does not set on the rubber feet of the cpu does it so should i install it at an angel?

No, don't set it at an angle. It comes with 4 pads that you can place on the bottom of the copper plate to essentially simulate the rubber pads on the XP's OPGA. Just take the same precautions you would installing any other heatsink and you should be fine. One end of the clip mechanism has a protrusion where you can place a flat head screwdriver. Guide the other end onto the socket locks and then gently lay the heatsink onto the core. For the other side with the notch, use a flathead to apply downward force and a pair of needlenose or angled pliers to guide the clip over the socket teeth to lock the CPU in place. With this method, you'll never place uneven force on the core so you have zero chance of cracking it.

PS: don't bother with a shim, it can cause more harm than good.

I have an SK-7 which uses what looks like the same clip. I can engage it by hand since it's plenty wide to get both hands on it. Just keep your hands off the heatsink. Levering the heatsink around is what's going to crack your core. Force that you exert on the clip is only felt by the CPU core dead-center, because that's where the fulcrum of the clip is located... directly over the CPU core. And pushing straight down on the CPU core isn't what's going to crack it.

First, Installation of the SLK-800 is a breeze. But you MUST apply the little rubber feet, that come supplied, to the base of the SLK. If you do not understand what I am talking about see THIS

Secondly, if you are using a small screwdriver to push the clip into place BE VERY CAREFUL that it does not slip and score your motherboard. Place a piece of cardboard under the "strike" point (Where your screwdriver would hit IF it accidentally slipped)

Thirdly, Post installation, sit back and watch the temps of your CPU go WAY down and enjoy!

Keep in mind that any spring loaded solution is a potential cpu destroyer if the proper steps are not taken! The SLK800 has spring clip tension that is higher than average. You can attempt installation with the mainboard still in the chassis, but if you cannot obtain sufficient clearance to use a screwdriver, STOP! The mainboard will need to be removed otherwise you may slip with the screwdriver, wreck your mainboard and the sudden snap back may kill the CPU! Some of the SLK800's I've purchased were missing these feet and the contact area is narrow enough that it isn't hitting the feet on the PPGA with 100% contact area. Still, I was able to install these coolers without incident. I do not recommend the use of shims. If for some reason, the shim causes the heatsink to be even slightly elevated from the core your temperatures will skyrocket and (if you're LUCKY) the cpu will overheat quickly but not burn out. Most likely, the cpu WILL burn out so I cannot recommend the use of a shim.

The most important thing is to ensure that you have room to use that screwdriver! Don't fool yourself into thinking you can get the leverage because once you get that clip down to 1mm from going around the socket lugs and the screwdriver handle hits something and you have to wiggle it around trouble will come knocking!

Cheers!

Installation was a breeze, but it did require more pressure than some others I've used. One more note worth mentioning: Once you have added the sticky feet to the HS and are attaching the rear clip to the socket be sure to check the clearance on the frint end, specifically the clerance between the lip of the socket and the cut out in the HS. If the HS is positioned too far forward it will ride up on the lip of the socket. This is an easy mistake to avoid. Just don't place it too far forward after hooking the rear clip.
