SK-6 Heatsink not sitting properly on top of CPU

[RyanO]

Epox 8KAH+
Athlon XP 1700+
SK-6 and TT-6026A Fan
Artic Silver II thermal compound

This is my Second attempt:

After installing my SK-6 heatsink on top of my new Athlon XP 1700+ processor I held the motherboard to my eye leveland I noticed that there was more space between the right side of the heatsink base and the CPU ceramic than between the left side of the heatsink base and the CPU ceramic. This heatsink is tilting to the left and is not making proper contact with the CPU core.

In my first attempt:
I ignored this originally and the CPU died few seconds after. I know..I know...(Don't flame me)

No matter how I place it..I do not seem to have it totally flat to the CPU core, as it seem that the Heatsink's Clip is placing more pressure on the opposite side, I did follw the instructions for heatsink installation as per AMD website.

I am looking for anyone to share your experiences, or any advices will be appreciated.

RyanO, i got an exactly same situation with u, i am just burned my xp 1800, and the cooller is sk-6 also, this is the bad thing about amd cpu that i dont really like very easy to burn, before that i am with intel cpu, i never burn it even i put my heatsink with not properly...

Anyone else with this problem? I just ordered an XP1700+ and the sk-6. Does this seem to be a problem with the sk-6 or the AMD chip. Any infornation would be appreciated. I don't want to fry my brand new chip.

Schmeph, dont change the sk-6 clip position and make sure u take off the mobo when u are going to install, so u can see the heatsink attach to the cpu properly or not.. good luck... remember the cpu is very easy to burn... less than a minutes

I've noticed the same type of thing with one of my SK-6's that I use on my P3-1000E. It's working, but I think that it would be more efficient if I were to fabricate some pads for the corners. I think that clip they use is just a bit too far offcenter.

You could try a shim I suppose...

sounds like the clip is turned around backwards

you need to take the fan off to swap it back right

 

[Pecos]

The clip may not be backwards. I've looked at mine and where the fulcrom of the clip hits on the HS, it is off to one side of the core of my P3 by about 1/8 of an inch or so the best that I can tell.

Now on the Celly-T 1.2GHz with the IHS, the SK-6 sits pretty nice.

It seems that I am not alone with this situation, a bunch of you guys are having the same problem.

My question is: Are you guys still running your CPU regardless of the uneven gap on one side(read my original posting) between the CPU core and the bottom of the sink?

How is that affecting your cooling temps?

Has anyone find out if its the clip or any fix that I can do to make evenly flat?

Thanks, once again

 

[Boonesmi]

it needs to sit flush with the core or you will destroy your cpu


are you sure the clip isnt backward?

 

[han888]

ryano, that's why i change my sk6 to alpha 8045

just be sure you sink is as far over left as possible (when looking down on it)...if it isnt it will hit the the socket and there will be a gap...

To All: Yes, like what Pecos has said, ya need to place some sort of pads to the gap where it is smaller than the other side of the base of SK-6 and the CPU packaging. A while back, I used the felt-pads from Walmart! it works good. It gave me more stability during gaming and gave extra 30- 40mhz or so. I know... SK-6 is sucks at this but you just gotta pay attention to the levelness of this and use pads to help even out. You can also apply many layers of clear tape on to the CPU pakaging. Apply layers after layers until it perfectly matches the highth of the CPU core. Then just place a SK-6 HS. That way you know for sure the HS is leveled. These methods are needed when the FCPGA Celeron and the Pentium chips. AMD chips have their own pads on each of the corners so that will help level it.

Read this linky, Text talks about the same issue and possible solutions.

anyone with good solutions for this matter?

Wow, I was about to start a new thread about this problem too until I read it. I spent 5 hours troubleshooting my new 1700+ the other day and finally realized the heatsink wasn't making contact. I was wondernig why I got 70C+ at 100Mhz FSB and I couldn't even get far into bootup at 133Mhz. I thought my mobo's temp sensor was broken.

Two things that might help:

1) Go to that the link above explaining the heatsink/socket problem. You totally have to get the heatsink as far down as possible (looking at it on my Soltek 75DRV-2). Actually, initially I had the heatsink on backwards. So that the part that sticks out is right where the socket is. After I flipped it around, it still had the same problems because I didn't put it low enough.

2) At first I put the clip on with the screwdriver side down and this pushed the heatsink up a little. So I put the clip the other way and I have it as down as possible and now everything is happy.
