Get a lint free cloth and a new razor blade. Lens cloth's for glasses work well. Make sure the surface of the CPU, GPU and both heatsinks are clean and as shiny as they can be, use some 91%+ alcohol to clean them if need be.

Now start with the heatsink bottoms. Put a rice-sized grain of AS on the center of each surface and gently rub it in circles with the lens cloth until it literally disappears into a transparent layer. This will fill the pits and grooves unseen by your eyes on the heatsinks and make better contact with the GPU/CPU later on.

Now, make sure you have the GPU and CPU ready to go and exposed. Put a rice-sized grain on the surface of either one, now use the blade to "paint" that dab of goo evenly across the surface of the processor top. It should look like a smooth layer if you do it right, not too thick, but completely covering the surface and without any bare spots. This takes a little practice, but it's not that hard.

Finally, clip the heatsinks back in place, being careful not to move them around too much once they are touching the CPU/GPU or the goo will be smudged and less efficient. It will take approximately 24-48 hours before the seal between the 2 components is 100% settled, but you will notice a drop in temps immediately of something like 5-10 degrees celcius. Best results are achieved after this 2-day curing period.

Good luck.

Artic silver makes a "cleaner". It's called "artic cleaner" (duh)..

I used a clean teeshirt to the wipe off the cpu and a credit card to "spread" the AS5 evenly...

Squeeze a small size about a couple of rice grain. Then thinly spread it all over the surface with a flat object like razor or whatever you can use. Evenly spread it and make sure to have a uniform thickness.

It should take less then in that picture for P4.

The Althon XP has a bare CPU core.

The size of a bb should be allot. I know my Tbird used prolly half a bb size. I find using a razor better then a credit card, but either will work.

I know Im just giving an example of how it needs to be thinly applied. I know the athlon has a small contact surface and it should need no more than a rice grain to obtain an even thin coat of Artic Silver 5. :D

i have tried that way to apply AS5,
but...

prime95-tt-low.jpg


running prime95 for 6:47 hours, max temp 58c with a side case open and blow it with big fan.
still to hot right? without OC (barton 2500) temp only -5 c.
room temp is27-30c without Air Cond.

thinking about this link
http://overclockers.com/tips1187/
maybe it can decrease the temp for some degree.

or should i change the tt tr2-m4 to a pipe 101 or polo 725?

any suggestion pls welcome
thx

I think anyone would find it very hard to keep a CPU cool when it is at 100 percent usage, and your room temp is 27-30C. (Air cooling wise, water cooling on the other hand, would/can do better)

I'm sure my AS5 has pretty much cured by now, and I don't see hardly any changes in temp.

ATM, my room temp is 78F or 26C.

Folding - bouncing 53-54C = Case 35C

I know if my room temps are lower, like 70F my CPU temps drop to 49-51C, and case will drop to 32-33C, folding. (idle temps would drop further 43-44C - Case 30-31C)

So the only point I'm really stressing, is room temp will hinder the air cooling solution you may be using.

i have applied AS5 to CPU & video for ~ 6 months, same day when i changed my video cooler to Zalman.
after i applied the AS5, cpu temps decrease 3-5c.
my case temp 32-35c. i dont know AS5 affect on my video temps, because when i applied AS5, i changed
the cooler at the same time.
video temps before: idle = 63c, full = 85c ++
video temps after: idle = 50c, full = max 59c.

must i reapplied them again?

in the night, the room temp decrease to 26-27c, cpu idle temp can reach 48c, full load ~58c
but in the *hot daylight* increase to 29-30c, cpu idle temp reach 53c, full load ~63c
(note: software "cpu idle" always running in the background).

with this room temps, i think my cpu/video temps is still normal right?
if i changed the other air cooler (pipe101/polo725), maybe its only decrease a few degree.
watercooling is expensive for me :) saving for new rig....

i will try to make my case have good air flow, so i can close my case.
its fun ... i must open a side of case before turn on the computer :p

i cant always turn the air cond when i turn on the computer, *electric bill saving*

thx guys!

I wouldn't be too concerned about GPU temps.

I do use a Zalman VF-700 on my 6800GS. It keeps the temps from getting above 59C, but I haven't checked when my room is 80F+.

Reason why I say I wouldn't be concerned, is that my 6800GS threshold is 120C. It is a setting I cannot change, and is a setting to where the GPU will start to back throttle to keep from getting hotter.

Not sure if it is the same with 6600GT's, but if your getting 63C temps, I wouldn't get to concerned unless it is effecting the rest of the system from staying cool.

I'd say your okay with the temp that you have, since your room temps are in the 80F+. Of course that is just my opinion.

Also I used the zalman thermal compound, rather then the AS5 on the VF-700. I wasn't getting great results using AS5, and didn't want to waste time reapplying it.

From what I can see, your GPU temps went down nicely, but your CPU temps didn't.

I'm running a Barton XP2600+ OC'd to 2196mhz (191fsb - cheap mobo) with stock cooler and generic paste (came with mobo) and my CPU temps never go over 52C full load (usually 48-50, it hits 52 and I know its time to clean the dust out). I have a cheap case with no side panel fan, an 80mm intake in front, 80mm exhaust in back, and the PSU fan (120mm). It gets warm in that room in the summer (even with AC - there's 4 PC's & monitors on 24/7), though I don't know the actual temp - probably gets up to 25-27C. What does your case temp go to? Mine's 36-39 IIRC.

I would try cleaning and reapplying the paste to the CPU, maybe you'll get a better 'seal'.

That said, 58C full load at XP3200 speeds is not a dangerous temp, but 63 is over what I'd consider safe (though it is still under the thermal limit for the CPU which IIRC is 70C).

Mike.

im using zalman vf700cu (full chopper) for video.
it comes with 8 ram sink, i put 4 of them, although it needs modification because my vga was an AGP.

here are my case pic:

last night i try John Cinnamon tips for cooling case
http://overclockers.com/tips1187/

but i dont have the 12cm fan yet
(update: i already buy 12cm fan) and i will try to put in like in the article,
here's what i do:
- put 2 x 8cm fan for exhaust
- put 1 x 8cm fan for intake in the side case
- put 1 x 8 cm fan near pci slot to blow the hot air from video out.
(i will change it to 12cm fan, and change the location according to that article)
- give a shroud for cpu and gpu.
- i close the side case

result (closed case):
(room temp 28-29c)
(case temp 36-40c with case closed, it was 32-36c with case opened)
cpu: idle at 53c, before it was idling at 68c when i close the side case
cpu: full load 58-60c

video: idle at 56c
video: full load 64c
note: this temp when i still use 8cm fan, i will change it to 12cm fan. im sure it will decrease the temp some degree.

this article is good enough, when i compare temp in "closed case")

6600GT threshold is 140c, and cannot be changed too.
before i change the video cooler, running at 80-85c, i got no error/freeze/artifact.
just worried about it will shorten its life, so i change the cooler.

now in my case (will) have
3 x 8cm fan @0,14A (2 exhaust, 1 side case intake)
1 x 12cm fan @0,28A (blow the hot air from video, out from opened pci slot)
1 x 12cm fan in psu

question again, can my tt 430w supply enough power for them? because 6600gt draw enough power too. or i should change all case fan power to an DC Adapter?
DC Adapter 1A is enough?

yes, i concern about my cpu temp, should i change cpu cooler to copper base? it cost 29us$ (pipe101 w/o fan).

thx for all ur attention

I good copper cooler should help.

This should be good:

http://www.newegg.com/Product/Product.asp?Item=N82E16835118102

This isn't bad either:

http://www.newegg.com/Product/Product.asp?Item=N82E16835118112

See if you can add 1 or 2 120mm fans to the case ideally 1 in the front and 1 in the back.


Make sure you remove the AS5 and re-apply it when you change the heatsink.

The exposed core on the Athlon XPs is quite small so use a very small amount and remove the excess AS5 with a razor blade or credit card as previously mentioned.

i have reseat my case for better air flow.
- adding 2 x 8cm exhaust fan
- adding 1 x 12cm fan in front of HDD
- take off 3 slot drive bay, replace them with a 12cm fan under the dvdrom
- adding intake 8cm fan in the side case.

result in room temp 27-28c, side case always closed:

cpu temp
idle 50c
load 58c

mobo temp
idle 39c
load 42c

gpu temp
idle 54c
load 63c

now my cpu and gpu temps is similiar enough wheter i close or open the side case.
now, im just worry about mobo temps, why its increased... before its
only 32c-36c max. now 40c ++

the 12cm fan under dvdrom blow fresh air directly to mobo. i have reseat the cables.
like in the pic.
i have put a small 3cm fan for mobo chipset (the one with "G 8X" sticker)
but my mobo temp doesnt decrease.
1. is 42c danger for my comp?
2. my Athlon XP got this code AXDA 2500DKV4D AQUCA 0321UPAW, it is ok for OC?
3. i cant find much brand for cooler here. i just can find this:

http://www.fastncheap.com/indonesian/detail.php3?barcode=002000T0007425
or
http://www.fastncheap.com/indonesian/detail.php3?barcode=002000T0007426

which one is better? both are suitable for K7 and K8. any links?

thx

No wonder. Your current CPU HSF isn't even designed for Barton. (looks like the stock Palomino HSF I used to have on my 9800)

The TT PIPE101 is fine for SocketA if that's the only decent cooler you can find in Indonesia. Make sure you get a decent 92mm fan for it not some crappy 80mm.
Any Thermalright SLK series will be even better if you can find one.

my comp cooler:
14-05-06_2137.jpg

14-05-06_2138.jpg

14-05-06_2139.jpg


i see, yes my current cpu hsf only 15US$ TT TR2-M4.
i can not find thermalright here, so maybe i will go to TT pipe101
with TT StreetFighter
http://www.fastncheap.com/indonesian/detail.php3?barcode=002000T0007418
or
THERMALTAKE SILENT CAT FAN 9CM
http://www.fastncheap.com/indonesian/detail.php3?barcode=002000T0007457

both can fit in a TTpipe101 right?

thx

Why most of you say that you have to spread it all over the cpu? Isn't it better just to put a little in the middle of the cpu and then put the heatsink without speading it?

Negative.

Grab a plastic card like a credit card, ATM card or similar plastic instrument and spread a thin layer of heatsink compound evently to cover the entire area of the CPU heat spreader evenly.

You should get better thermal conductivity that way.

... thats what i do right now,
spread AS 5 with an ATM card ... thin layer...,
yeah, i think i must buy a new cooler + good fan for barton, a sempron + mobo
and a refrigerator too
i must saving money for married next year
lol


im planning on TT pipe 101 and TT silent fan 90cm
because i can find them here.....(can not find TR product here :( )
any other idea?

thx
