Can't Re-Attach Heatsink

September 7, 2009 at 20:53:03
Specs: Windows XP, Intel Core 2 CPU 6600 @ 2.40 GHz / 2 GB RAM
Hi everyone. Thanks a million times over in advance for your help. OK so here's the problem. My computer is housed in an Antec Sonata III case. It has an ASUS P5K motherboard, and an Intel Dual Core CPU (E6600 I believe), and 2 GB of RAM. There is only one hard drive (500 GB). I've had this computer since July of 2007. Great performance and no real problems until recently.

For some odd reason, the computer suddenly turned itself off the other day. Every time I'd try to restart, within seconds to minutes it would shut itself off again. I quickly deduced that the components inside the tower or whatnot were overheating, and that this sudden shutdown was some kind of protective measure being enacted by the computer...and sure enough, removing the door on the side of my Antec case to allow better airflow & avoid heat being trapped in there did the trick. At least, it did for about a week. Now the same problem is back.

I was concerned because I don't know much about computer's inner workings or about cleaning them safely. Washing the air filter inside the case was accomplished, and I did my best to try to clean the fan (though it's very difficult to reach & clean properly, especially since I don't have a screwdriver to really unbolt the entire inner workings of the case to let me get at it properly). Anyway, I still was having problems and so upon looking at my manual for the ASUS P5K motherboard, it occurred to me that I may need to remove the heatsink, clean it, and reinstall it.

I was able to remove it simply enough. Cleaning it - well, there was some dust etc, and it's *cleaner* than it was, though it seems a difficult piece of equipment to properly clean. Anyway...reinstalling the heatsink is the real problem.

There are 4 holes on the motherboard where you ostensibly push the pegs in and thereby lock the device back in place. Problem is, the pegs are jiggly and loose and don't seem to want to hold the heatsink in place at all, no matter what I do!

As we speak, I am using this very computer....with the heatsink 'held in place' by gravity alone (i.e. the case is lying on its side). Amazingly, it's working. But I don't feel good about this, and I'm worried this may be temporary at best, and indeed may even be damaging my computer somehow.

One more thing - as soon as I restarted the computer with the loose heatsink held in place by gravity alone (and the wires connecting it to the fan sensor) the BIOS reading of the CPU temperature drastically changed. It had been 73 degrees Celsius before for quite some time; now it's reading 29 degrees Celsius.

Anyway...thanks for bearing with me thus far. What I need to know is, how can I safely reattach my heatsink? Or is the current solution workable? As odd as it is, I could probably live with keeping it like this - assuming it was safe for the computer. I'm one of those people who never even thought to touch or learn about things like heatsinks, so I'm coming at this from a complete noob point of view.

Many thanks! Any more pertinent information to my situation would be greatly appreciated too. *hugs*

Have you tried to buy a new Heat sink as a replacement? You totally whacked your own heat sink you know.

Did you re-apply paste to the Heat sink ?

Also the LGA775 HS7F have plastic turn screws on each leag to lock in place , easier to buy a new HS&F which bolts thru the motherboard..

Dear MWCC,

Thanks for your post hon. I realize now the shutdowns were all the result of the heatsink being slightly loose already, before I even removed it to try & clean it. Leave it to Intel to make a great piece of equipment...that uses ridiculously substandard, flimsy pegs to stay put.

As I said before, I'm a noob when it comes to all this. So I wouldn't yet know what 'paste' to use or how to use it. If I ever buy a new heatsink, I'd need it to be compatible with my Intel Dual Core E6600 CPU and ASUS P5K motherboard. Can you recommend one that is? And if so, could you please provide a link to more on said heatsink? I'm worried I might buy the wrong thing otherwise when the time comes. Thanks.

That said, I can't really afford to buy new computer equipment unless it's necessary. As things stand, the CPU is running at a cool 29 degrees Celsius. The heatsink is where it always was...but it's being held in place by gravity alone, with the computer case lying on its side to accomplish this. What I need to know is:

Is the current solution workable? And if not, how can I safely reattach my heatsink? As odd as it is, I could probably live with keeping it like this - assuming it was safe for the computer. Again, I'm one of those people who never even thought to touch or learn about things like heatsinks, so I'm coming at this from a complete noob point of view. Please bear this in mind when replying. "Buy a new one" or a vague "wow, you destroyed it" does not answer any of my questions, and does not help me, lol.

Many thanks! Any more pertinent information to my situation would be greatly appreciated too. *hugs*

Well if you cnat afford to buy one have you tried to see if you can afford at least the bolts/ screw that is used to attach the heat sink? also why don't you try to reattach it again but this time start on where is the loose side is.

Lycan...as I said before, this Intel heatsink is very good, but the pegs for it are absolutely crap. Cheap, plastic, difficult and in my estimation unfixable (and even if they were replaceable with more of the same, who would want that? They're terrible!)

As to reattaching it...there is no "loose side." The entire thing is unattached. The pegs do nothing to hold it in place. The heatsink is currently being held in place by gravity alone. And as I've said before, since I'm a noob to heatsinks, I haven't the slightest idea how to go about reattaching one, let alone safely (apart from the pegs of course, which are broken nonworking crap).

Don't get me wrong, I appreciate your posting...but it would help if you would pay more attention to what I said in my previous posts, because basically I'm just repeating myself here to you. You see what I mean?

As things stand, the CPU is running at a cool 29 degrees Celsius for nearly a week now. The heatsink is where it always was...but it's being held in place by gravity alone, with the computer case lying on its side to accomplish this. What I need to know is:

Is the current solution workable? Is it safe to operate my computer with it like this?

And if not, how can I safely reattach my heatsink? As odd as it is, I could probably live with keeping it like this - assuming it was safe for the computer.

You to what I have read (many times) you said you tampered with heat sink and ended up can attach it properly back. Which means you might not remove it properly and you end up getting it loose. Now to what solution that i can see is to get a new heat sink set for the processor that you are using. So this called pegs will included if you buy that new heat sink which will replace the broken one.

But still this is just a option. You could to detach and reattach it again to see if you can attach now.
