Yes, you can use Arctic Silver on the CPU, but this will void your warranty.

Its the Nvidia Quadro

I believe the cooling difference comes from the redesigned heatsink. they probably change it from the cooling pad thing to a larger metal contact surface.

On the T60 under high GPU load the GPU always goes higher than the CPU. On the T61, both are basically locked together going up and down.

for anybody still having high temperature issue with a Thinkpad T60P, this is a *cheap* and *really easy* mod to lower temperatures.

I tried this on my thinkpad and the GPU is now idling at around 61 C where it was 76 C before.

The steps:

1. Get rid of the thermal pads on the GPU and Northbridge (useless), but keep one around for later.
2. Clean the surface where the heatsink meets the GPU and Northbridge
3. Reseat the heatsink
4. Put a thermal pad and put a penny on the pad at the location pointed to in the picture below on top of the heatpipe. The pad would be on top of the GPU heatpipe and is there to make sure the penny doesn't slide around.

5. Put the piece of metal that holds the heatsink back in place on top of the penny and screw down tightly.

This ensures solid thermal connection between the copper heatsink and the GPU & Northbridge, and temperatures are much lower now than before. The fan also shuts off now after being on for a while, which NEVER happened before.

No offense, but sticking a penny on top of a CPU, GPU, or even a northbridge without being perfectly flat and polished it going to *KILL* that item. Not enough heat transfer can take place through the little surface contact a stock penny would have pressed against the other surface. That is unless you mean something...

Surely freddy418 is expecting you to use a penny produced between 1793 to 1837 since it would have been pure copper, and then trim both surfaces with a grinder to be perfectly smooth/flat. Let’s not forget that since large cents were rather large, you'd also have to trim the sides to get this old penny to fit inside your T60. Otherwise, a modern penny's composition is only 2.5% copper and you would definitely be SOL!

The composition was pure copper from 1793 to 1837.
From 1837 to 1857, the cent was made of bronze (95 percent copper, and five percent tin and zinc).
From 1857, the cent was 88 percent copper and 12 percent nickel, giving the coin a whitish appearance.
The cent was again bronze (95 percent copper, and five percent tin and zinc) from 1864 to 1962.
(Note: In 1943, the coin's composition was changed to zinc-coated steel. This change was only for the year 1943 and was due to the critical use of copper for the war effort. However, a limited number of copper pennies were minted that year. You can read more about the rare, collectible 1943 copper penny in "What's So Special about the 1943 Copper Penny.")
In 1962, the cent's tin content, which was quite small, was removed. That made the metal composition of the cent 95 percent copper and 5 percent zinc.
The alloy remained 95 percent copper and 5 percent zinc until 1982, when the composition was changed to 97.5 percent zinc and 2.5 percent copper (copper-plated zinc). Cents of both compositions appeared in that year.

freddy418, can you tell me what kind of thermal pad was on GPU and northbridge ? How high was it ? As thin as a some thermal grease or a few mm ?

On my T60p, I plan to use a sheet of copper to have a got contact with heatpipe and keyboard base.

=> own6volvos, I understant he place the penny between the heatpipe and the small metal part. So heat can got from the heatpipe to the keyboard base *crossing* the penny and the reuses thermal pad.

Hmm, makes me wonder if slapping on plain ole transfer pads on top of the GPU section without touching anything else would also do the same thing. That way if you need to warranty the machine all you do is remove the thermal pads stuck to the bottom of the keyboard and its back to "stock"

I meant put the penny between the heatpipe and the metal clip. The point of the penny is to apply pressure to the heatsink so that the copper heatsink touches the GPU and Northbridge.

Why bother replacing the material? why not just not have anything (except some thermal paste) between the GPU and Heatsink like my mod?

I just don't explain my self very well in english. :( I will remove the thermal pad from the GPU and use Arctic Silver 5.

On my T41p, it's not possible to do that because thermal material is about 3 or 5 mm high. On T60, it looks thin enough to be relplacer by only thermal grease.

it's not thin enough to be replaced by thermal grease alone, I put the penny (although any material ~1/8 inch thin would work) there to put extra pressure on the heatsink so as to push the heatsink down onto the GPU and Northbridge.

Freddy,
What is your temperature reading now that you have metal2 metal contact with the gpu?
My current readings are
AC (no battery attached)
Idle:
RPM 2943
CPU 48°C (0x78)
APS 35°C (0x79)
PCM 37°C (0x7a)
GPU 61°C (0x7b)
BUS 41°C (0xc0)
PCI 45°C (0xc1)
PWR 44°C (0xc2)

So I wish to perform the mods listed in this thread to decrease the temperature even further. I wish to find out if the the time/effort
are worth the rewards.

thank you

My results have been nothing short of amazing. I have reduced my idle temperature by about 20-25C. I highly suggest that anyone who is having heat problems clean out their fan with some compressed air or otherwise.
I just did the same (finally) with a can of compressed air. My laptop is pretty new (2 months or so) and hasn't been in any really dusty areas so I was a bit skeptical about this.

In conditions which normally ran my CPU up over 100 C, I was still able to hit 103 C after the cleaning. This was with BIOS settings for fan control. I switched to manual mode (max) and my fan RPM (and noise) went up by ~1000, but it's still sitting at 103 C. It even crept up past 107 C after a few more minutes of very moderate use (WoW, not moving at all).

Also my idle temp seems to be the same 75-79 C. All of these temps are for GPU (by far the hottest thing in the system).

So I guess the compressed air via the fan vent thing didn't work for me. I've opened my machine a couple times and I've never found any dust or anything that would indicate it was dirty inside.

My readings after being idle for about 15 minutes:

of course, without ambient measurements, this is hardly useful. My GPU idled at 73°C before the mod though, so it was certainly worth the effort for me.

It really is, the metal to metal contact mod works great for cooling this thing down a bit.

Freddy,
your temps seems a bit high just for idling, what mode were you in?
if it is in LowMode, have you have done all the software tweaks to reduce gpu temps ?
CCC
PowerManager

because in case you did not notice my temps are for a T60P.
which I would think would run higher temps than yours.

I just put 2 thermal pads that I had laying around inside the T60, and it dropped the temp ~4C of the GPU. I stuck one on top of the silver tension bracket centered over the GPU, and then another on the GPU heatpipe about an inch or so away. Turned the bottom plate of the keyboard into a big heatsink for a little bit of heat energy, and now the fan turns maybe 20% of the time, instead of staying on 100% after the laptop was on longer than an hour or so.

Shucks, you beat me to it,
I was just about to ask on how to use the bottom plate of the keyboard, to disipate heat.

my questions:

how thick are the heat pads that you have?
does the keyboard buldge out then?
does the kb become hotter?

general questions how hard are those heat pads
I am thinking of cutting them up and lining the top of the
heat pipe with the so they will make contact with the keyboard.

thanks

I had these left over from a netgear business switch that I used artic silver on, no clue who might sell the material itself.

They were about 1mm thick 1" x 1" squares. To make them firmly contact the pipe and keyboard I had to fold the one above the heat pipe 3 times, and the one on top of the metal tension bracket twice. Since the material can compress a bit, once everything was tightened down I noticed no buldging.

In terms of extra heat at the keyboard, I never took measurements before, but currently the right side is 30C and the left side is about 33C.

Thanks freddy418,

This is what i did:

1) Opened up system, removed the silver tensioner and heatsink.
2) Peeled off old thermal pads. One was thicker than the other.
3) Slightly (and VERY gently) bent the heatsink part that goes over the GPU so that it would sit lower.
4) Cleaned the CPU, GPU and lower chip of any gray residue.
5) Added a small drop of Arctic Silver 5 onto the CPU, GPU and lower chip.
6) Screwed the heatsink back on.
7) Placed 2 pennies inside the bottom of the silver tensioner, side-by-side (NOT stacked), so that they sit above the GPU and the lower chip. I used a white sticky thermal pad from a VGA card to stick the pennies into the tensioner. They fit perfectly.
8) Screwed the tensioner on.

My GPU idle temps used to be ~77-80C. Now it is ~67C.

Hi freddy418,

Yesterday, I recieve my T60p. It was nice during about half and our time it gets hot. The fan starts to spin more and more and never stops. After a few 3D Mark 06 to check if nothing goes wrong, GPU temperature reach 95°C ! I let it cool down with the fan running. GPU was still at about 65°C with planty of noise.

So, I look at some copper plat within all my computer stuff. I found a T41p fan assembly. It's main plate is about 0.8 mm so exactly the height of the thermal material of the T60p HSF. I put the T41p in the oven to melt solder and remove heatpipe to get the copper plate. After two hours, I got 33 x 25 x 0.5 mm fully mirror polished. I carefully remove the thermal material from the T60p with a cuter blade and place some Arctic Silver with two smal adhesive points.

Now, my T60p fan assembly get in touch with the FireGL V5200 trough full copper and Arctic Silver. I also got a copper plate from the T41p HSF 33 x 25 x 0.8 mm and I place it on the two heatpipes (with some Arctic Silver) of the T60p HSF so this copper plate get in touch with keyboard base.

I screw everthing up and boot the T60p...

Now, with NOT fan running, my T60p (using TPfancontrol), the GPU is at about 67°C. During games, it set the fan at level 1 (about 2900 rpm) and run 3 times 3D Mark 2005. The GPU only reach 80°C with some peaks at 85°C. After 85°C, TPfc gives the fan control to the bios. Less then 20 seconds after 3D Mark, GPU temperature is down to ~65°C. I set up TPfancontrol so fan runs at level 1 when GPU reach 75°C and stop at 62°C. Most time in office application and web browsing, the fans did not run. Laptop base is not too hot and dead quiet !

If I let the fan running at level 1 while working, GPU temperature is at less then 60°C. :D Now, I love my T60p !


Here is what I got with a clean installation of Windows XP (bios controls the fan 2900 rpm) :

CPU 44°C (0x78)
APS 34°C (0x79)
PCM 33°C (0x7a)
GPU 58°C (0x7b)

GPU Heat Issue / Fan noise

#201 Post by Truthfinder » Sat Jun 30, 2007 9:47 pm

This was one of the most interesting posts I've had the pleasure of reading. If was to say the least very informative.

Could someone advise me on how to check the Temp of my GPU. Do I need a utility program or is there someting that included with my T60 that would off this info.

Kindest regards, one and all.

Very interesting post Pascal_TTH. My thoughts were right that those nasty thick thermal pads were no good for the heat dissipation. I do not own a T60p but I'm glad you've figured out a way to fix the heat issue on T60p's.

Here is a pict of my modded fan assembly. Tape is used to be sure the second copper plate won't go away even with high temperature when Arcti Silver tends so *slide* :

http://www.tt-hardware.com/img/news5/ne ... dujour.gif

Between the two green text, you can see an other copper plate from the T41p HSF : is allow heat to go from the heatpipes to the keyboard base.

Unfortunately, my wife delete picture from the camera... I have any pict of the copper plate alone.

Now, here are the numbers :

- with fan fixed at level 1 with TPfancontrol (~2900 rpm) :

CPU 42°C (0x78)
APS 33°C (0x79)
PCM 35°C (0x7a)
GPU 55°C (0x7b)
BAT 50°C (0x7c)
BAT 27°C (0x7e)
BUS 38°C (0xc0)
PCI 42°C (0xc1)
PWR 41°C (0xc2)

- without running the fan after 90 minutes web browsing, mail, mp3 playing, basic usage :

CPU 61°C (0x78)
APS 44°C (0x79)
PCM 46°C (0x7a)
GPU 72°C (0x7b)
BAT 50°C (0x7c)
BAT 36°C (0x7e)
BUS 48°C (0xc0)
PCI 55°C (0xc1)
PWR 57°C (0xc2)

- then running the fan for 5 minutes, temperature drop is very fast :

CPU 49°C (0x78)
APS 40°C (0x79)
PCM 42°C (0x7a)
GPU 62°C (0x7b)
BAT 50°C (0x7c)
BAT 36°C (0x7e)
BUS 46°C (0xc0)
PCI 50°C (0xc1)
PWR 49°C (0xc2)

I setup TPfancontrol to run the fan at 72°C and stop it at 60°C. So, now, the fan run for 5 minutes every 60 to 90 minutes. That's fine for me. If the GPU reach 85°C, TPfancontrol set the fan at 3400 rpm. At 90°C, TPfancontrol give fan control to the bios. But but my modde fan assembly, I never see more then 85°C. At 3400 rpm, fan and *my* thermal solution is powerfull enough to cool down the GPU !



Perhpas I will order two new fan assembly (T60p et T41p) and solder the small plate from the T41p on the T60p HSF. It seems that copper plates in fan assembly are soldered with tin/pewter (not sure of the name, but like all electrical solder). It melt on an electric plate for coocking tin can spread all over the small copper plate and will fix on the cold T60p fan assembly... That's my future project !

Again very interesting post Pascal. I wonder if you could help me out on something. My T43p M10 heatsink when activated at level 1 I cannot feel like is expulsing enough hot air, I mean I've tested other T42's and when the fan is running at 2900rpm I can feel more volume air coming out the vent than the air expelled from my T42p. As a result the CPU temp would decrease very slow when the fan is activated even if the CPU multiplier is set to 6x. My CPU have Arctic Silver 5 on it, as the FireGL core. At load the CPU would max 64C (at 1.052V), normal use CPU temp is 45-48C with the fan ON all the time.

Was wondering if there's something wrong, should I use a FRU specifically for my T42p type?

Here is some exemple of how effective is my tweak. I stop the second run of 3D Mark 2005 and take a capture. With BIOS fan control, fan runs at 3400 rpm and GPU is at 78°C.

Hi xtr,

You have a T43p fan assembly within your T42p !? I suppose you use TPfancontrol or NHC to tell about voltage and temperature. Check with TPfancontrol how fast run you fan.

I got an idea that can explain you issue. The fan amp is perhaps diferent between T42p and T43p fan. So, if T43p fan is for exemple 0,3 amp and the one of the T42p 0,2 amp, your mainboard did not give enough power to make the fan run at the exepect speed.

Note : Power (so fan rpm) is amp x voltage

I also mod the fan of my T41p by replacing the pad with Arctic Silver. As the pad was not too hight I gently bend the thermal plate to be sure it stick to the FireGL. But, one time, a friend ask me to do the same. I bent it too much and hear a *crack*. After what, I looks like the heatpipe doesn't work any more. GPU was getting very hot.

What about you GPU temp ? Is it fine ? I can post some temperature about my T41p with it's fan assembly.

Thanks for yourinput Pascal. I will elaborate more:

I'm sure the T43p fan does work at the basic 3 rotational speeds (2900, 3400 & 4200rpm), the fan is noisy using on the lowest speed when I'm in a quiet environment. Supposedly T41p/T42p heatsinks are more silent.

I'm unsure if the motherboard doesn't provide enough power for the fan to operate, but another issue is that my machine have a 2373-GEG which according to Lenovo site it appears as a T41p motherboard (basically the same as a T42p mobo right?)

I also bent the heatsink so that it touches the GPU core, and to make sure the heatsink sticks to the core I placed a folded piece of paper just above the heatsink before installing the keyboard. Load temps on the FireGL (78-80C), idling 50-52C (fan toggling ON/OFF because of the GPU).

The reason I have a T43p HSF was because my machine came with a T42 short HSF assembly, the GPU was overheating when gaming. So I got a T43p HSF assembly as a replacement.

Would be OK if you could post your T41p temp readings.
Also, is your T60 CPU undervolted (68C reading at your last pic)

Hi xtr,

I start some bench to see the temperature. I use RMclock to feed the CPU with less voltage and TPfancontrol to handle the fan slower. But the following results come from the T41p running with bios fan control and now voltage soft lowered.


I stop during a 3D Mark 2005 run, fan is at 3700 rpm :

CPU 69°C (0x78)
APS 51°C (0x79)
PCM 32°C (0x7a)
GPU 69°C (0x7b)
BAT 32°C (0x7c)
BAT 24°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)
XC3 0°C (0xc3)

The T41p gets quiet hot considering the fan speed. Also, I need to tell that it's a Dothan 1.7 GHz within (not the original Banias 1.6 ou 1.7, I don't remember). If I force low fan speed (level 1 = 3000 rpm), the FireGL T2 128 Mo reach more then 80°C :

CPU 74°C (0x78)
APS 53°C (0x79)
PCM 33°C (0x7a)
GPU 82°C (0x7b)
BAT 33°C (0x7c)
BAT 24°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)
XC3 0°C (0xc3)

Now, I will let it cool down without fan (half an our later) :

CPU 51°C (0x78)
APS 51°C (0x79)
PCM 38°C (0x7a)
GPU 55°C (0x7b)
BAT 35°C (0x7c)
BAT 24°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)

Here is how my T41p is without fan (on with no activity).


I read some post about long and short fan assembly. In the T41p, it's a long one. It think it's the same for T40p and T41p. I don't know for T42 and T43, I didn't have any of them (mostly because the graphic power was not far higher then on T41p).

Thanks for the temp readings Pascal.

I wonder which voltage you have set on your T41p (at 18x multiplier): 69C seems pretty high, unless you haven't applied Arctic Silver 5 on the CPU. I get about 74C with stock voltage and AS5 at load.

Judging the GPU temps I think I get about the same readings, though a bit low than yours (78-80C).

Right now I'm having trouble gaming old games (F1 2002, F1 Challenge). I installed rFactor and the screen went progresively white (as when I had the GPU overheating, but I'm sure the temp was not an issue here). Those games freeze and I've to press Ctrl+Alt+Del to terminate the process. I suspect there's something wrong with Direct3D Audio as DxDiag reports an error. I'll reinstall Windows later this week.

It was with deflaut voltage. Otherwise, it runs at 1,1 volt when freq is 1700 MHz. Here are the temp with fan forced to level 1 and 1,1 volt

CPU 64°C (0x78)
APS 52°C (0x79)
PCM 32°C (0x7a)
GPU 69°C (0x7b)
BAT 33°C (0x7c)
BAT 24°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)

With Bios fan control and 1,1 volt

CPU 64°C (0x78)
APS 52°C (0x79)
PCM 32°C (0x7a)
GPU 69°C (0x7b)
BAT 33°C (0x7c)
BAT 24°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)

I used Artic silver 5 on the HSF. I was playing Morrind on the T41p, I never encounter an issue. I play a lot of games with my desktop and some are quiet unstable. But a screen witch turn to white is strange. Overheat brings most time green dots, untextured area, flickering triangles and so on.
