thinkpad and silver 5...........(56K be aware)

[Dead1nside]

What did you use as a cloth?

What did you use as a cloth?

I know that you could use coffee filters as they are lint free.

However, how thin should the layer of AS5 should be?

[Dead1nside]

However, how thin should the layer of AS5 should be?

The layer of arctic silver should be very thin, it is merely there to fill in the tiny gaps between the heatsink and processor surface.

Putting a large blob on only serves to decrease heat disapation.

Thanks looks like I'll buy some coffee filters. Anyone else got any ideas?

[agarza]

Ok, but it should be applied evenly I think

[Dead1nside]

My best advice is to apply a half pea size drop to the bottom of the heatsink in the middle. Then when fixing it down, it will spread out to cover the centre, and almost upto the sides. This is what you want.

SO, I should apply the AS5 in the heatsink or in the CPU ??

[mhca]

When I am appylying thermal paste (usually Arctic Silver 3 has been what I've used) I make a small drop on the core of the CPU, nothing on the heatsink.
I then stick my finger into a clear plastic bag of the kind used to put food in the freezer (not the kind you get in the supermarket ) and then I softly apply it using my finger to spread it evenly over the surface of the CPU core.


I haven't tried doing this on my thinkpad.

And btw concerning the thickness of AS5.... 1-2 mm is way too much as others also have written. Only use it to even out the imperfections of the heatsink/core surfaces.

[Dead1nside]

One can apply to either, but it is easier with the heatsink. There is no wrong or right way. Think about it, when the heatsink is fully attached any gaps between it and the CPU will be sealed by the AS5.

If you put say a whole pea-size drop on it. You might get a little coming out the edge. The most heat is disapated centrally. That's why you apply it to the centre so it spreads out. If the very edges aren't covered, it does not matter too much.

[agarza]

OK. I did the procedure 1 hour ago, and it seems the laptop is running about 5C cooler than before:

CPU: Before --> 45-47C After --> 42C (stable temp)
GPU: Before --> 52C After --> 49C

I see not big improvement, but I think I did a good job applying AS5 on the CPU core & GPU.

[Dead1nside]

Congratulations. With AS5 i think a 5C drop is all that one can hope for.

On my desktop rig, however, with a new heatsink and AS5 and extra silent fans, I managed to drop 25C. Which really helps as in the summer (and in general) the heat really builds in this small unventilated room.

The Athlon XP was getting to error temperatures, where mistakes were being made in the core.

[agarza]

I ran a game, and after a race in NFS Most Wanted, the CPU temp rises to 74C and the GPU to 85C, is that normal??

[crashnburn]

any significant temperature after putting the silver5 as shown above. Beside, what is "purifier" that you used, is that alcoholic liquid? just wonder whether can i used the alcohol to wipe away the dirt on GPU, and original thermal compound.?

That solution is Arctic Cooling Arti-Clean - most likely alcohol based but far too expensive for what it is (high price, small bottle).

Go down to your local chemist and ask for propan-2-ol or Isopropyl Alcohol - it's what most people use to clean thermal goop. It cost me £8 for 0.5L but you only need 100ml really. Try not to use Acetone (nail polish remover) as it leaves an oily residue - something which IA doesn't.

I can't wait till my new processor arrives - P-M 755 (2.0ghz, 2MB, 400 L2) so I can dump my Banias 1.6 - the [censored] hot thing!

Those pics look great - I notice you didn't remove the screen like it says to do in the HMM - was the IBM guy drunk when he wrote that?

IBM guy wrote it? Doesnt something like this void warranty?

[Dead1nside]

This is what I thought. However, I'm sure there's no way of them to know. If you swap back the components you've swapped out.

How are the temps with the 755? From the banias, as I'm doing about the same thing.

[agarza]

My CPU temps have gone again back to normal, with the CPU idling at 47C and the GPU now in the 55C.

I've read that I need to burn in the CPU to allow the thermal compound to work 100%.
I let the computer burn in for 4 hours, then I would shut down it, and then again run the burn in.

Who knows more about this?

[Dead1nside]

I let the computer burn in for 4 hours

4 hours is more a "standard usage session" than a burn in. Burn in means that the AS5 will cure in the coming weeks, to reach it's final temperatures.

[DesolataX]

Replacing the thermal compound makes that much of a difference???
Wow, I have to do that on my T43, that thing gets quite hot...

So, what do you recommend is should do?

1 hour ago I was playing NFS Most Wanted, after a long chase (10 minutes) the screen went black and I had to power off the machine, guess the GPU became too hot.
Did I do right removing the brown goop in the GPU heatsink?

Idle temps now look like this:


Is this normal or did I apply AS5 in a bad way?

[DesolataX]

Did you put AS5 on the GPU and the CPU? or only the CPU? because the GPU will also need AS5.

[jch]

Did I do right removing the brown goop in the GPU heatsink?

I removed the dark brown thermal rubber pad from my T41p's GPU initially, but when test-fitting the fan back in place it looked like there would be no way that the copper heat sink would be able to sit snugly against the GPU--there was a 2-3 mm gap.

So I put a layer of AS5 on both sides of the rubber pad and stuck it back on the GPU.

My GPU now runs cooler than my CPU. Previously, my GPU was always 5-8C warmer than the CPU.

If you still have the rubber pad, I'd suggest you try reinstalling it on the GPU.

jch:

You mean the pink film by using the word thermal pad???

[censored], I threw it today, and there's no way I could retrieve it because that bag is gone.

However, I did try to fit the heatsink into making contact with the GPU and it did, however it still gets very hott.

[censored] pink film

Also, how much memory your GPU has? 128 or 64MB?

[jch]

No, I mean the spongy dark brown pad that is about 2-3 mm thick (1/10")

Also, how much memory your GPU has? 128 or 64MB?

32MB

[agarza]

But he brown goop is now a rubber pad, just a thermal compound, isn't it? In order to remove it you need to completely dissolve it with ArctiClean, so I guess there should be a misunderstanding.

I see you have only 32MB in RAM, guess your GPU doesn't generate too much heat than my 128MB FireGL T2

[Dead1nside]

As I said a burn in will take upto a month or so. It just means, after a lot of good solid usage. In all conditions. On all the time. On and off etc.

You might as well put AS5 on all the other chips as well, while you're at it. I did it with my northbridge on my desktop and that helps. It's best to cool everything down if you can.

You mean applying AS5 on top of the T42p northbridge?? Wouldn't that lead to, in the future, to gather dust on top of the Northbridge core?

I'm too lazy to open again (3 time) my T42p to apply it on the northbridge.

A quick one: If I do not run NHC or TP Fan Control I could expect the same temperatures as with the factory thermal paste?

Another thing: My T42p CPU runs @ 51C after playing NFS Most Wanted while the GPU runs @ 57C degrees after 20min I exit the game. Im not using NHC nor TP Fan Control. Are those values normal? I'm quite dissapointed because I've been unable to really lower the temperatures of my Thinkpad.

Everyone of you with normal use, the left part of the keyboard that is just above the CPU gets hot?? (Mild hot, or no heat at all) ??

[Dead1nside]

Not ontop of the heatsink inbetween it and the heatsink. Putting it ontop wouldn't do anything.

Those temperatures are normal.

It is normal to feel heat whilst typing at the keyboard, this happens with all laptops.

[agarza]

I need anwers please:

MY CPU runs @ 1.8GHz with Voltage of 1.196V, Max Performance.
CPU Temp is 47-50C just browsing. It goes to 55C when watching movies, etc.

The GPU However, using the nirvana001 method runs @ 52-55C constantly all the time, independently if I'm not gaming.

I made sure the heatsink contacts the GPU, but would be a good idea to put a slice of aluminum foil (kitchen) and place it between the top of the GPU with AS5 and touching the heatsink so that there's a little extra contact between the surfaces??

[jch]

Only if you want the copper heatsink to corrode in a hurry...

Dissimilar metals heated in direct contact--big no no.

Hope this helps,

[agarza]

OK. Thanks for your reply

However, is it normal to have the GPU temp over 55C when the machine is web browsing, listening to music??

If I start Prime95 the CPU tops 61C but the GPU stays about 2 degrees cooler.

Any suggestions to improve heat dissipation?

[zaku]

i just applied as5 today. but i see no big difference in temp drop.
but weird thing is that when i leave my laptop on without touching it for a while, the temp is like 3c higher (@43c) than before when i didn't applied as5.
and when i'm just simply browsing the net, it then drops to 39c.

before applying as5, i had ~40c when not using the laptop and 41-42c when i start browsing the net.

looks like it's doing the inverse job?!

and do you guys had those temp drops right after u applied as5 or after the break in period??

You can't complain. You get quite a low temp (39C-42C). What's your ambient temp?

My CPU constantly is about 50C, and even when I did a lot of Arctic Silver 5 applyings to see if I was doing things right.
What I've noticed is that before AS5 was applied the fan was constantly at 3500rpm's, but now it only reaches 3000rpm.

It appears that when you leave the laptop on without doing anything, the temp raise a few degrees. But If you start doing something, the fan will somehow pull out the heat from the inside more effectively that's why the temp decreases.

My Max CPU Temp is 64C, using 1.196V for 1.8GHz Pentium M.
Ambient temp is about 27-28C
GPU max temp is about 80C, when gaming, increases rapidly when I exit the game.

////////////

It seems some laptops run cooler than others, mine is one of those laptops that run very hot. Independently that I applied AS5 the correct way.

In my Thinkpad T30, after applying AS5 I noticed a very noticeable difference. The CPU can be cool down to 34C when making the fan to run at full steam (4200rpm). Temps are about 42C-50C, the fan starts at 50C and decrease the temperature quite fast.

Did you undervolt your CPU??
What's your GPU temp, idle, max load?
