Can I fix this motherboard hardware problem?

[jameshanley39]

oops - I've already put the heatsink onto the old paste & have been
running the unit... 'gulp'

did you check the CPU temp?

er, I know I could probably find out on google, but as I'm already
here, do I just wipe the old stuff off?

no, you need the right things to do it. se other post in thread about
99% IPA and lint free cloth. Wiping both heatsink and CPU. And how to
reapply. also check the arctic silver site for reapplying instructions
of arctic silver paste. you'll need to buy some AS paste.


If you follow the AS adhesive advice. then, my understanding, and it
could be wrong, is. THe adhesive stuff is not between the CPU Core and
Heatsink. Use the AS paste between cpu core and heatsink. Adn the
adhesive between heatsink and CPU(blobs on the green part - non core,
and avoid those metal lines on the processor).

I noticed the site for AS adhesive says not between CPU and heatsink.
my reading of the posts here tell me that the instruction of the site
should more correctly say , nto between CPU core and heatsink. No
doubt they didn't design it for your situation, but from posts here, it
seems to be strong enough. Just make sure you put the adhesive on the
green. And the AS paste on the core. Fortunately, since this is a
public forum, i'll be corrected if i'm wrong!

I hope i am making things clearer. you said you hadn't used AS paste
before. It actually sinks into little holes in the heatsink. So you
can't just wipe it off. Other post in thread discusses this. It
should appear by the time this post appears.

Thats interesting Andy cos I don't know much about this stuff - what
you see in the pic was how much paste was there when the unit arrived.
Now that its working I'm reluctant to take the heatsink off again. Is
there a downside to having that much paste on there?

yeah, major downside. failure. CPu getting too hot. I don't know the
science, but

, it onyl works properly when there's a thin layer of arctic silver
paste over the core(that rectangular or square thing in the center of
the processor). The layer should be very thin, e.g. smoothed out with a
razer blade. You have to be careful about applying it. don't touch it
with your fingers.

The arctic silver website has instructions on how to apply it.

Regarding cleaning it off and reapplying, I use the same safe method
I use when cleaning thermal pads off heatsinks or CPU cores. Maybe you
have to use this method even with paste. 99% isopropyl alcohol and a
lint free cloth.

To get the 99% IPA. (at least in the UK) You go to a chemist (a real
one,not a big store). And then, you ask for the chemist (he's gotta be
wearing a white coat). And you ask him for it. He should give it to
you. IF he asks then tell him it's for cleaning. Most *Real Chemists*
will be fine with it. It's not always easy to find a real one.
Sometimes you ask for one and a guy in a suit comes out and tries to
sell you some 50% solution of something.
Don't think of drinking it, that 1% of isopropyl can cause brain
damage. It's not Ethanol. I also, only use it outside 'cos i've read
that it's nto good to inhale or get on skin - so I wear plastioc
gloves. (Though a scneitist friend says it's ok to inhale a bit or get
a bit on the skin, he uses it all the time and it's one of the safer
things in his science lab!)

get lint free cloth. Regarding what it is..! Lint is bits of thread.
So a tissue, if you wet it and rub it on your trousers, would shred a
bit. THose shreds are called lint. any shreds are called lint. You
want a cloth that doesn't disintegrate like that. Jiff Cloths are a
brand name in the uk. Or immitation jiff cloths. Or those cloths for
cleaning lens on glasses.

A Razer blade for thinning the paste over the core.

Clean the heatsink adn the cpu.

Alternatively, you could just get a thermal pad. but they are not as
effective at cooling. You still have to go through the whole cleaning
job though.

Regarding the 99% IPA. THereare alternatives. But some have drabacks.
AKASA(a company of whome I bought a heatsinks that broke AMD
specifications!!) make a fluid for cleaning CPUs. So I would avoid
that. And some people talk of using Acetone. But apparently if you get
that outside the core of the CPU, it'll go through the CPU or burn it,
so forget that. 99% IPA is the proper stuff. If you cant' get
that, then maybe AKASA's fluid. But if you can even get 99% IPA in the
UK, (with some difficulty , talent and technique) you can get it
anywhere!
