    hi all, new here...

    i've built two systems to date, so i pretty much know what i'm doing, but have the irrational fear of the AMD boogie man story that heatsink application to the cpu must be PERFECT or else the world ends...

    i recently purchased and installed a new heatsink from www.quietpc.com because the old one was incredibly loud, and on the test run, the heatsink actually FELL OFF THE CPU!!! (i know, i'm an idiot...) and the system turned off immediately (thank god!)

    anyway, does anyone have any experience to catasrophic failure and mishaps with AMD cpu's?

    if you crack the die, will the system still work? what if it has minor heat damage?

    i'm typing to you now ON the system that this happened to, so it SEEMS to be okay, but i'm worried that the functionality belies a deeper horrific problem... so, anyone?

    I'm one of those....lol
    Fried 2 AMD's and cracked one ...
    Basically on one of the AMD's upon install and power on , smoke came up , die came apart ( easy to see since i haven't had the case on..). The other one burned too but no smoke came out since the case was on ( just that i wasn't able to power on). The cracked on it was on the side of the die....
    I have to say that it's NOT AMD"s fault ( well not quite , it would be nice if AMD would have a heat spreader like P4 ) but the manufacturers of the heatsinks...
    Basically if you go with an "el cheapo" one , chances are that it will burn ... :D
    Now if you can adjust the core voltage ( in BIOS ) might wanna play with it . For example on a AMD 1.4 266 which the BIOS would run it at 1.75 ( stock ) i was able to use it without any problems on a 1.675 V along with an Alpha PAL8045 and a Panaflow fan ( which reduced the noise and keep it at a 100 F under normal load )
    And to be honest there are a whole lot of guys with burned cpu due to "el cheapo" heatsinks.
    There are couple of tthing that can help avoid all those problems.
    1. Do spend some money for a good heatskink ( Alpha,Thermaltake,GlobalWin ) with a copper plate.
    2. Do not put a whole lot of grease. Just a little dab and do use ArticSilver paste ( a bit more expensive bur worth the price)
    3.Install the cpu and the heatsink while the motherboard is out of the case ( that way you don't have to apply a whole lot of force and also have easier access to see how it seats into the socket)
    4. Some guys do install you what is called a shimm , but in my experience ( and i did build 40+ pc's with AMD's cpu's ) it's not need it if a good heatsink is used.
    5. Do take your time when installing a heatsink don't rush it , as it might crush the die , thus making the AMD a nice key chain rig :(
    HTH

    so you're saying that the system wouldn't respond at all if i had damaged it? as i said, it's running right now, so if that's the case, i'm golden... :D

    the heatsink i got is a radial fin design with a low rpm fan, to reduce noise... it's not a cheapy by any means...

    here it be...

    it is really super quiet! pretty amazing. the hard drives are the loudest thing in the case now, which i'm surprised at, as i thought my power supply was the major culprit.

    anyway, i still don't feel out of the woods yet, but i'm feeling better about this...

    Well the system boots up then you should be ok but ...
    1. i wouldn't touch the heatsink ( as in try to put a different one)
    2. the heatsink that you have looks pretty good, so again you shouldn't try to install another one
    And yes, most of the times with an AMD ( well with most of the cpu's ) , if you start the puter and there are no beep and no signal on the monitor , the cpu is the culprit.
    So thank your lucky stars that is working :D

    My 2 cents, active95

    has more experience as I have only built a few AMD systems but, if you cracked the die or burnt the chip, the machine would be toast!!! You only get one shot at such a failure. You are probably good to go. I have never used a spreader and have never had a failer.

    Just an opinion,

    SeeYa

    thanks, both of you... yeah, the system has been on now for almost 12 hours straight, so i think i'm aright... ROCK! the new sink/fan is really super quiet and runs the proc cooler as well! now i just have to quiet down the HDD, and all will be right with the world...
