RadioShack Paste isn't cutting it?

I just built my computer. I am on a budget. Here it is...

2500+ Barton
Shuttle MN11N or something like that.
256mb ram
9200 video card.

Anyways, I had to buy some RadioShack thermal paste because I live in a small town and couldn't find paste anywhere. I put the thermal paste on, turn on my computer, and watch the temps climb. They start at 40C and go to like 60C and above and then my computer turns off by itself.

BTW: this is my first time using thermal paste, I used a pad last time... :rolleyes:


What could I be doing wrong?


Thank you!
 
I just underclocked my barton to 1.09ghz. Then I installed Motherboard monitor. It is saying 188 degrees Celsius for my cpu diode? and -1C for my case temp? and -68C for my cpu socket?

What the hell is going on?

:D

thanks

try putting a heatsink on top of the paste aswell ;)

if youve already done that just keep reseating it, even with poorly applied paste and a stock heatsink it shouldnt do that so it cant be on properly
 
Abouta zillion things could be wrong , but most likely you don't have the heatsink mounted to the cpu properly .

things to check :

thermal past usage: use only a thin coating of paste . The stuff is designed to fill the 'microscopic' differences in the mating surfaces . It is NOT suppose to form a thick ass layer between the cpu and heatsink ( those thermal pads blow chunks BTW , you'll be happy to have seen teh back side of them for good )

Heatsink mounting : you currently may have some issue with the way your cpu and heat sink are connecting , by this I mean they may not be mating together with the maximum surface area touching . check to see if maybe you have accidentally gotten the sink on a bit cock-eyed ( yes it's possible , and yes it's easier that one might at first imagine )

if you are wondering 'how do I check that ?' , very carefully remove the heat sink and look at the thermal paste on the bottom . what does teh squished imprint pattern look like ? If it isn't exactly even and the shape of the top of the cpu core this is wher eto start solving your trouble


big guns: make sure your heat sink /fan combo has enough capacity to cool your cpu , if you are using an old sink/fan it may not have ehte dissapation capacity you need .

if all else fails reread the title of this post
 
you have MBM ( mother board monitor ) set up incorrectly ( make sure you have it set to your mobo /chipset ) it is possible that MBM does not have the proper setting for your mobo or has some special problem with the sensors ( though the only one I know of that has problems is the older ECM k7a ), but that is pretty unlikely,

edit : er, wait underclocked ? that process could be monkey wrenching a few things . but I might add why bother underclocking ? Your heat output is function of the number of transistors in the cpu and the voltage they are running at , unless you can seriously reduce teh core voltage ( NOT RECOMMENDED as the amperage will come up in compensation ) your heat output will not be signifigantly reduced by underclocking . ( sure it will go down a little as you are not firing the transistors as fast but not enough to make it worth the trouble ), and if part of the underclock is a bus speed tinker then the resultant IO (mis)sync might explain the MBM errors
 
ok, I have been playing Halo for about 15 minutes now...

When I touch the heatsink, it feels cool. I haven't had any problems with it shutting off.


I still have my processor underclocked though... :(



Thanks for the input...
 
oh I see Rild, thanks for the great edit... I didn't think about that, cause I didn't lower the voltage.

I will keep the voltage at stock and go and get the ghz at stock...

just a minute...
 
ok, so I put my processor back to stock... It overheated just as I got to the first window boot up screen...

My heatsink is on perfectly from what I can tell...



What in the hell is going on? :D


thanks
 
mmhh you got me , if it runs underclocked but not at stock then either AMD secretly sold you an easy bake oven and mislabed it a CPU or you still have some kind of heat sink trouble ( I would still bet on a mating / moutning problem ) .

Is the heat sink a stock ( as in came with teh cpu) heat sink ? And does the heat sink actually feel hot when the machine shuts itself off ? how are you checking the CPU mounting?


( p.s. check for magic heat elf droppings inside the case , an infestation of those bastards can cause no end of trouble )
 
I would say.. re apply paste.. but follow the guide from the website that shows you how to apply arctic silver... i don't remember teh site.. but i'm sure you can google it

well this processor worked great for about 5 months at 3200+ speeds with only the thermal pad, and the same heatsink/fan (stock).

The HSF doesn't fell hot at all when it is on, or just after I turn it off...


It seems fine at 100mhz x 11...


oh well...
 
If the heat sink doens't feel hot then perhaps there isn't good contact between the die and the heat sink.. i would say remount and re-paste..

I'd say bingo on that ,

very carefully , inspect and re-mount ( no this is not a pr0n diretors quote , well not this time ) .


The core or the HS might not have a flat mating surface( wouldn't be the first time ) and if that's the case you might have to go back to the pad unless you want to lap ( which isn't that hard really )
 
I think there is probably more difference between two people mounting the same heatsink than there is between the best compound and the worst compound---in many instances.

Be very careful, make sure you do a neat job, and even that radio shack compound should be good... unless you picked up the insulating calk by mistake. :D
 
However much thermal compound you are using, it's too much. You should be putting a TINY beat of that stuff on the heatsink, then spread it around a little. Make the coating fine, use a knife. Then, use a knife or credit card, and spread a tiny, fine layer on the core fo the CPU.

If you use too much thermal paste, no matter how good it is, it will act like an insulator. You just want to put enough of this stuff on so it fills the tiny little holes between the CPU core and the actual metal on the heatsink.
 
ive been using RS paste (from 2 yrs ago) and its working just fine with my cpu(s)

temps are decent, prob cause i have an alpha pal 8045 heatsink on it :)
 
ok, some suggestions:

Try some other thermal paste, that's one thing, but even with a cheap thermal paste, it should still be working to some extent. It sounds like yours isn't working at all. maybe you should take some pictures of what you're doing as you go along so that we can see and make suggestions.

Also, I would look at your heatsink, and make sure it's clean from any previous thermal pad/paste. Do this by using Isopropyl Alcohol preferably as high of a percentage as you can get. CVS is a good place to get this. Also some Q-Tips to clean off everything before reapplying anything new.

Your heatsink should be smooth, very few scratches if any.

Also, you might want to check your motherboards heat diode. And make sure it isn't bent up to be touching the chip. That is if your motherboard has that in the middle of the socket.

You mentioned that you had this processor running as a 3200 previously on the pad. You might have done some damage to the processor by running it too hot for a while. Stressing it too much can do that.

Those are just some ideas.

188c? QUICK JESUS RUN FOR YOUR LIFE!!!!!!!!!!!@#!$!$

my very safe bet would be that 1) that program isn't working right
or 2) the sun has relocated to inside your computer

My heatsink does have a couple nice scratches right down the middle...

that must be it...
 
I don't understand. You claim to have run a locked 2500+ Barton @ 3200+ speeds (~2.2GHz) with a thermal pad and stock heatsink??? And now you have radioshack paste and it only runs at 1.09GHz? Seriously, for what you are attempting, a few scratches in the heatsink won't do anything compared to the crazy insulation of the thermal pad. Can you even feel the scratches by running your finger over them?

What case are you using? Perhaps there isn't any airflow to your CPU fan?
 
OMFG!!!!....

You guys will never believe this...


I HAD THE FUCKING HSF ON BACKWARDS!!! :p


Since my stock heatsink has the copper circle a little off of the center, you have to have it a certain way. I had the fucking thing turned 180 degrees... I turned it around and now I'm running it at stock...


Thanks for the help guys!


BTW: MBM is still saying 212C, but the BIOS is saying like 42C :confused:
 
Glad you got it all figured out. Would have hate to have seen a decent 2500 get trashed because of something stupid.
 
FIXED, excellent ,excellent ,

hehe , don't fret teh mis aligned HS it happens ( at least once ) to the best of us :)
at least you were spared teh smoke test of maximum unquality assurance

you probably need to go in tot he control panel for MBM and choose the proper mother board ( my guess is that it is currently set to the wrong specs for your board )

and 42C ain't bad for air cooled ( it can ALWAYS be better of course;)

It's better than the sun being inside his case. :p Not only would there be no sun in the sky, but his cpu would melt.
