what does "your heatsink is on backwards" mean???

[jjyiz28]

i don't get it. heatsink im aware come with clip retainers on one side and also on the opposite side. so you are only able to clip it one of two ways. does it matter which way? i mean the hs/fan looks more or less symetrical if you rotate it 180 degrees.

Look at the underside. Hey, it's got a step cut into it... that's to provide clearance over the raised solid-plastic end of a CPU socket, where the lever swivels. If it's reversed, the heatsink cannot make square contact with the CPU core.

Also, look at the clip. It's not symmetrical, is it? The pressure point is offset. Ah so...

drats, the picture is not there. could you send another one, while i re re re read what you posted. =)

Sure thing, I goofed up on that last one. Try this: link to photo

And here's a guide I refer people to a lot: Guide That's in PDF format, so hopefully you have Acrobat Reader. Look at Figures 7, 13, and 14 for the important things to know and watch for.

Dude go to this link for some more pit falls to avoid.hey it says there and shows you why you should NOT use Arctic Silver http://www.slcentral.com/articles/00/8/socketa/page9.php .. the same ppl ive been using that for ages and had noticed this but just thought ahh nevermind must just be normal ..

I done the same thing with a heatsink. It was a round copper base and i didnt notice the little curve to tell we which way it goes, i nearly cracked the edge clean off the die ..

ah , you are right mech. looking at my innards, i see that i have installed it correctly. its common sense actually when i installed it on, hmm the socket steps up, so the hs with the depression go right on there. can't believe people actually put it on backwards. maybe if they rushed it but still, only takes a little common sense thats all. thanks for the links.

if you had done it backwards, be sure you would have noticed it. To be more precise you would have heard it and smelled it.

Man, that article is old and it shows the downside of using the original AS whereas AS2 and AS3 do not have that issue, it even says in the article:

Arctic Silver II is out and it has a HIGHER VISCOSITY than regular Arctic Silver! And so far, this higher viscosity seems to be enough to prevent the pumping phenomenom!

That's not necessarily the case with AMD based systems anymore. I can leave the heatsink completely off on my Soltek SL-75MRN-L and the CPU won't fry thanx to the ABSII reading the on die thermal sensor of the 1700+ t-bred I used. If I attempted to boot up without it the system no sooner recieved power than turned right back off again. On subsequent attempts there was no reaction, just as if I fried it. However, put the cooler back on with the coolermaster premium paste on it and the system boots up and overclocks like mad again. Some boards, including mine, even have clock throttling you can set in the bios to preform much the same function as the Intel's do.

yeah,my Abit NF7-S also has thermal throttling

Isn't it more likely to HEAR it ?
craaaack.

It's a simple jump-to-a-conclusion that is common.

>can't believe people actually put it on backwards
More people do it than admit to it. That and letting the sink slide over so its just barely resting on the socket step.They'd rather say the CPU died mysteriously. Why is my temp so high!? Some people never realize what they've done.

I've always found that sense is rarely common.
