What kind of temps are you seeing?


Well... After I first installed it, with an adequate amount of paste, I
got
39C at idle. BTW, my case is always open. My CPU is 2000 XP. My fan is
Thermaltake 6cu. At this point with

a) an open case
b) un-airconditioned apartment
c) idle

I get 59C.



Close the case and get some intake and exhaust fans to get a good air flow
through the case. Make sure the HSF is rated to protect the XP2000. Generic
Radio Shack grease works just as good as anything, make sure it is a very
thin layer, and that you have the HSF mounted correctly.

There were people selling fake stuff labelled as arctic silver...

What CPU is it and which thermaltake heat sink? What fan are you using
on the heat sink? What type of case cooling scheme have you applied to
get air flowing through the case?


I just left the case open. Most of the stuff I described in my other reply.
I found that opening a window in the room on a winter day dropped the CPU
temp sometimes by 5 degrees. Although it became really cold the room
itself. )))

Okay, I red your other reply. The 6cu is barely adequate according to
the AMD site, but it is adequate provided your CPU is the tbred version
(model 8). If it's the palomino (model 6) then it is not adequate.
Aside from replacing the heat sink you could try attaching a more
powerful fan to the unit (my tbred 2000+ is the retail boxed version,
and its HSF works fine and is surprisingly quiet).

Also, how much is an "adequate" amount of thermal paste? It should be
very little. Along these same lines, the past changes a bit after the
CPU has been in use for a while after initial heat sink installation.
If you've jiggled the heat sink or removed it and reinstalled it you'll
need to clean off the old paste and reapply a new thin layer.

Finally, what's your room temperature? I don't know where you live or
the temperatures in your unairconditioned apartment :-)

NYC. It is hot as hot as it used to be two weeks ago.

The fan on the heatsink is running at 7600 RPM. It should be pretty
adequate.

The amount of past was not too much. I tried to spread it as evenly as I
could. I cannot describe in words how thick it was. Definetly not thicker
then paper, like most sites say it has to be.

It is definetly a newer core CPU. So my question is what is a GOOD heatsink
for it? All-copper?

open the case, use a small table fan and blow. worked for me this summer

Hello all.

Is there a definitive guide to cooling AMD CPU's. Like which heatsinks are
the best? What trick to use?

My constant problem is that after I apply arctic silver paste and mount a
ThermalTake heat sink, average temp seems to climb over period of time.
Maybe its a knock-off paste?

Just put a small dab of regular white Radio Shack compound in the center of
the CPU...pushes out the air.....easy as pie.

Wipe CPU and HSF with alcohol first, look to see if there is any lint or
hair.

You should be running around 40c idle and 50s on a hot day after running at
100% for 20 mins.

Remember tho that some mobos give very inaccurate readings. A very nice
Biostar I use is famous for reading 10 degrees high.

BTW, I know this methods works cuz when I remove a HSF there is a
transparent square thinly outlined by white compound on the underside of it.

Or you are using TOO much.... All it's supposed to do is fill any air gaps between the
HS and the Proc... Too much and it acts like insulation and you take the chance of it
getting slobbery and flowing down the sides of the die...

You know, I've tried all the expensive NAME brands to the el cheapo generic radio shack
pastes - as far as I can tell - they all work the same... I've never had any problems
using the cheapo "Knock-off" paste...

Try this - pull your Proc with HS attached. Carefully remove the HS from the Proc and
clean off all the old paste from both HS and proc... If the old stuff looks like a wad of
squashed bubble gum, you had WAY too much of it in there...

Using a piece of very fine emery paper (600 grit or so) - buff up the bottom of the HS
until it's shiny - make sure it's clean. Remove any manufacturing burrs or tool marks,
any scratches etc... It should be mirror shiny or as mirror shiny as you can get it.
Give the Proc a similar treatment - but be very gentle (I use a little toothpaste on a
cotton swab) ... You can't make it shiny - just make sure that it doesn't have any high
spots. Just make it as smooth as you can safely make it... Restrain yourself from
buffing off the painted on printing (if there is any) ...

Make sure you don't have any grains of crud, no dust or goop, etc... Clean them both
carefully, and place a very small dollop of thermal paste - A round dollop as long as it
is wide as it comes out of the tube - onto the center of the HS face - squish that down
onto the proc rotating it back and forth centering the HS as it should normally be on the
Proc. You are trying to squish out as much of it as you possibly can! DO NOT put more
than ONE dollop...

A very small amount of paste should squirt out from EACH edge - that's good - remove it
with a toothpick - then try rotating it again - Be gentle - don't force it to rotate - if
the HS rotates easily, you still have too much paste in there - if it takes effort, you
probably have the correct amount. Remember, it's NOT glue, Your concern is that there is
NO air between the Proc and the HS. The layer of paste should be as thin as government
toilet paper!!

It takes a little bit of practice... So do it a couple of times until you get it
correct... Before you stick the assembly back into your machine, make sure that you have
removed any excess paste that squirted out with your toothpick...

if you did it correctly, you should see a marked improvement in your temps...

My machine is under load right now in a 90dF room - mbm5 reports my machine's temps as 36
ambient - 48 CPU It's 9AM... By 4PM it should be about 110dF in this room, and I would
be very surprised if my machine tops 60c under load... And I don't use any name brand
Cooling junk... All stock fans, Generic HS etc.. Duron 1.1 G - slightly overclocked to
1.2 - If it gets over 60C - I'll down clock it back to normal until the weather gets
cooler...

You haven't got your side off have you? After I applied some paste a few
weeks ago, I left the side of my case off, and it went up about 8C in 2
weeks. I applied some more paste, and put the side of my case on, and now
my temperature is steady. So suppose must be dust getting on the heat sync
or whatever.

Of course it will be maybe 5 to 10C warmer with the side on, but better than
leaving the side off if the temp is going to go up.



More likely the airflow is better with the side on instead of just
turbulance with the side off.

Wrong..
Air flow is better with NO box at all.
MB vertical, cards horizontal is most common today, and worst
of all possible worlds.
Doesn't much matter if the CPU needs a heat sink though.
(Direct Convection is nil now. and vertical fins are best.
- Auxiliary fans on CPU are "just one more thing" to go bad.

The main fan is needed to cool the "enclosed" power supply.
It "sucks" air into the (presuably closed) box in which it's installed.
(Blowing into a box, just don't work too good. (Takes a pump, not a fan.)
Other fans in the box try to do the same thing.
I think the only place there's any "turbulence" is in the immediate
vicinity of the fan blades. (As the air "struggles" for a way to exit the box")
and just goes round and round. the blades.
