Did I break something?
I am replacing a bad mobo. While trying to jiggle the replacement
into place, I think I may have broken a bond on the (NB?) heat sink. http://www.newegg.com/Product/ImageG...%20Motherboard After I heard a snap, I checked the bond on the old heat sink. It was still bonded, but it also made a snap when I moved it. What should I do? I tried taking the heat sink off, but I am not really sure how it comes off. It has two hold down pins that have springs under them. Do you pull the pins? Twist the pins? Push the pins? I have some heat paste. Do I just need to re paste the heat sink? |

I can't recall ever having to get into the BIOS PC Heath Status for a valid condition on runaway CPU temperatures from a disconnected or faulty heatsink. That's however is the first thing recommended that always need be done when finished with a working build, check what the BIOS CPU sensor is reporting. |

It was like I had broken the glue holding the heatsink to the NorthBridge. The old mobo was still bonded until I intentionally tried to break the bond to see if that is what I had done to the new mobo. |

The old mobo was still bonded until I intentionally tried to break the bond to see if that is what I had done to the new mobo. No idea what the snapping noise is. Heatsinks sometimes use plastic pushpins. It's a pin, consisting of two legs side by side. The pin is a compression fit, into the motherboard hole. The legs expand to fill the hole, and the end of the legs catches on the motherboard material. http://www.acousticpc.com/images/a_z...onents_pic.jpg To remove one of those, you need to compress where it catches on the motherboard (on the solder side of the motherboard, not the top). If you use pliers, they tend to slip off (because there's no good surface to grip onto). Then, the motherboard may get scratched, or an SMT component gets knocked off. Presumably, there is a good custom tool for compressing them, but I've never seen one for sale. You can cut the head off the pushpin, with diagonal cutters, but then, you need an exact replacement pin to take its place. They use pushpins in automotive applications, but in those, there is a screw in the center of the pin, to "lock" the tip of the pin in the splayed position, so it can't come out. The computer version, just relies on the springy properties of the legs, to keep the pin secure. Paul |

The old mobo was still bonded until I intentionally tried to break the bond to see if that is what I had done to the new mobo. Yea, I run into some of that snap-crackle & pop with a MSI 775 / Pentium 4 last week I sent back when it wouldn't post. First time up with a 775 and I wasn't overly impressed with the aftermarket CoolerMaster copper heatpipe setup. More along the adaptation that CoolerMaster. You've an AM3 socket, unless I misread, so we *should* be in the same field as my new and first AM2, (old Orleans single core), which I now like just peachy since figuring it's hidden key sequence for advanced BIOS settings, and an old Ghost, non-Enterprise version that was giving me grief. That 775 seemed loose, at the time I was doing it -- I was thinking: This sure is a load of happy crap, what I'll do is replace the surrounding CPU support anchors (plastic rivets), probably with small brass screws/bolts and paper washers. AMD2/3, however, is basically the same (so's Intel 478 socket for that matter), different cosmetics but anchored with into the black ABS plastic surrounding cowling with white neoprene-like inserts. However, the backplate of the AMD MB, I recall now, has an additional plate beneath the CPU's plane to reinforce it from stray torque. Which is a good deal. As long as nothing is actually coming up or detaching itself, though, the creaks and moans you can probably live with. Just keep that in mind and favor it for a potential subpar design factor when working around the CPU. Flexing MBs, though I don't like creaks and cracks either, seems unavoidable unless in total disassembly and laying out the mb with a mousepad or something for support backing. Download and install SpeedFan, it does conditionally still monitor the CPU temp for an event launch, and could even consider soldering the CPU fan directly off a spare PS adaptor for safeguarding the MB pwr-fan slot in case the bearings/sleeve freezes into a load condition. Or replace it if it can be adapted to AMD. I the cowling for 478s at geeks for two and change, and tossed one in for stocking stuffers to make up shipping costs. |

I guess my question should be.......if I have broken the contact with the heat sink and the mobo, should I repaste it? I did not remove it but it pulled away from the board. I thought it was the North Bridge, but it may be............Side Port memory. It has 3 heat sinks. It has the large CPU heatsink and a smaller one that is still pretty large and there is another small flat one the size of a large postage stamp. It is the middle sized one. It has to wing type fins........??? It is shown in the pictures. It is blue and marked ASUS in the pictures. |

Looking at the picture of the underside and comparing the position of the pins shown on the 'plan' picture; On underside pic; Zoom-once-to the middle mobo-fixing-hole that is on second-row-down. About 10mm down-&-right is the end of one of the NB-HS fixing-pins. (Other pin is appropriate distance going in same direction (down&right)) Zoom-in as far as you can to said fixing and you will see that it is quite clear and that the hole is round with a slot through it, the pin is same shape but held in place by being 90deg offset from hole. Thus; Push, Twist and Pull ! (useing appropriate tool in the cross-heads of the fixing-pins) |
