New homebuilt computer shuts off within 2 min. CPU temp is over 180F. 1

[SKreme]

I just built my first computer. About a minute or two I turn it on it just shuts off. I have an AMD athlon xp 2800+ processor. I am using the heatsink fan made by cooler master called the dream 7. Here are the numbers in the bios:
System temp: 26C 78F
CPU TEMP: 83C 181F
CPU fan speed 2721 RPM
System fan speed 0 RPM
Vcore 1.69v
+3.3v: 3.24v
+5v: 5.08V
+12v: 11.43
-12: -12.11
-5v: -4.94
vbat(v) 3.29V
5vsb(V) 4.97v
My friend suggested that I try to reapply the thermal paste. I am going to try that over the weekend. Anyone have any other ideas of what the problem could be? Your help would be appreciated!

Heatsink on backwards or no thermo paste applied (if it came with the factory yellow plastic strip, carefully remove it before you apply the paste). Is heatsink fan even turning? Wrong plug on mobo? Raised part on heatsink goes over lip on CPU socket (matches for good fit). Pray you haven't hurt the CPU!

Funny, I took apart an old IBM p3 667mhz for spare parts the other day.
We also bought them brand new and never did aftermarket heatsink replacements on them and this one still had the yellow plastic cover on the thermal strip when I removed it from the proc... It happens I suppose.

I'm suprised it ran as long as it did.
The motherboard was actually what went belly up by the way.

When Intel CPU's get hot, they just "throttle" down. When AMD CPU's get hot, they just keep on going 'til they burn up.

What micker377 said...any new news?

My heatsink was on backwards! Silly me. I sent the CPU back and they are sending me a new one. We'll see how that goes... I was just wondering... my heatsink fan says that its for AMD 3200 and up. Mine is a 2800. This shouldn't be a problem, right???

 

[paparazi]

As a retailer I always look at statements like yours with a bit of annoyance, I guess you told the retailer that you put the heatsink on backwards right? nuf said.
yes no problem, it's always better to get a heatsink/fan rated higher than needed.
Also if your case hasn't already got them ? extra case fans are a must, at least one extra (first one, fit below the PSU exhausting) second, front lower drawing IN cool air.

Since Micker377 immediatly hit it square on the nose - Have a star, since nobody else has given you one.

Cheers!

No disrespect to micker377 but they are cheaply given stars, anyone who has ever built more than one socket A machine knows this basic fact!
micker377 was just first to post
Infact in the last year I have seen this ANSWER given 30/40 times to high temps on socket A (unfortunately so called technical uses are still fitting socket A heatsinks the wrong way round)
We used to get an average 2 to 3 returns a week on OEM Athlons for exactly this reason, until we insisted on FREE FITTING all the socket A CPU's that we sell (unless we know the buyer)
I personally can't believe users are still making this simple mistake! it has been so widely reported since the original Thunderbirds came out some 5 years ago?

I agree with paparizi, this comes up too often - especially when pictures are printed in the instruction manuals. Sometimes I reply, sometimes I let someone else reply.

I've built more than one SocketA and even replaced my heatsink with an aftermarket one.... And I didn't know it was that common, or even possible. It fits one way and won't the other unless forced. (I also usually ignore overheating AMD posts)

I guess I've never been forceful enough to "make it fit" backwards. You don't need to be superman when working a PC - hand tight is usually more than sufficient, and if it does not fit quite right - take it off and have another look.


Most hardware I touch these days are in servers or my home machines, and I can hear the mighty lashing of a whip were I to "make things fit" in our bladecenter.

I thought I'de seen it all though. Mammoth dust bunnies. Sticks of memory broken in half from putting them in backwards and RAMMED in the socket(what did they use, a hammer or something?). Firewire and VGA cables forced in upside down. No plug in the wall... etc.

The thing that has really been bugging me lately is the excessive number of posts telling the user to inspect the motherboard for "cap bulge".

...As if the standard user has desoldering tools, knows what capacitor to replace it with, and can sucessfully resolder it. Yes, it's easy, IF it's the offending part and you have actually touched a soldering iron before. (I've replaced a few in my amps before)

I think both welding and taking my car engine apart/putting it back together are easy too (thanks to prevoius jobs). I would never recommend a friend do them without my help though.

Ahh,.... old age.

CreamCake quote:
"It fits one way and won't the other unless forced"

I'm afraid I'm going to disagree with you again, sorry.
Socket A heatsinks don't need to be forced to get them on the wrong way, the raised cambox only just touches the heatsink, we are talking 0.5mm at most, this is why it is so easily done and I suppose why so many fall into the trap, there really isn't any extra effort involved fitting them incorrectly.

Putting the heatsink retaining clips on right is usually real easy (except Volcano brand!). Putting the clips on with the heatsink backwards, is usually more more difficult. If you have fight it - check it!

CreamCake: I have a printer (lpt type), that a client actually forced the data cable in backwards! It smoked.

 

[CreamCake]

A fine thing. I now have the urge to take my 1800+ heatsink off and see how easy it is....

It may be an excuse to get my p4...

And I'll take my star back if you dont want it micker!
I was just giving you credit for a helpful & speedy reply.


c:\del star.*

Thanks for everyone's quick replies! As Paparazi said, after fitting it on a couple times both the right way and the wrong, its just as easy either way. And by the way, there were precious little instructions and even the few that were there were VERY unclear. Paparazi, my case comes with a fan on the outer wall. It originally was blowing air OUT. I unscrewed it and refit it to blow the air IN. Thanks for the suggestions!

 

[micker377]

I ain't complainin' about the star! Thanx

 

[paparazi]

The only reason for my insisting socket A heatsinks fit easily both ways, is to try, if is were possible, to save many people the same grief.
I just felt by implying it was almost impossible to do and that it would need to be forced, implies to users that this isn't an issue ie:
"You'll know when you're fitting the heatink wrongly because it won't fit unless forced" just wrong sorry.

As SKreme points out, quote:

"after fitting it on a couple times both the right way and the wrong, its just as easy either way"
This comes straight from the horses mouth so to speak.

Guys don't take this the wrong way, I am really just trying to be accurate and if any of you have ever burnt out an Athlon XP, you will know just how easily it can be done.

These links are too late for SKreme, but perhaps they can be used as reference by others. Page 14 of the .pdf guide addresses heatsinks installed the wrong way.

I'll attempt my retrofit soon.

However, also in the spirit of accuracy - I'll have to say "anyone who has ever built more than one socket A machine knows this basic fact!" is also wrong. I've built 2!
(3 if you count replacing the OEM heatsink on mine, though my heat issue was airflow related... cheap generic case)


I'll learn from this thread ... (this time), but NEVER assume we all know this.

I've been in IT for 9 years and perhaps my weakness (or strength) is not enough experience with AMD. I only chose one for home since it was cheap. I still would not buy one for a work PC.

 

[paparazi]

The whole socket A heatsink phenomonen will disapear into obscurity over the next year or so, now the platform has been designated "entry level" and assigned to AMD's Low end Sempron range.
The emphasis of discushion will, as it is already doing, move on to AMD's midrange and toprange Athlon64's, socket 754 and 939 and the new PCIe Geforce4 based mainboards.
Where I hasten to add, the CPU and heatsink locking mechanism looks and behaved very much like it's Intel counterpart.
It won't be long before the majority of our midrange builds are well and truely Athlon64/P4 with just the odd budget Sempron/CeleronD thrown in for those on a budget.
