T60p CPU/GPU temperatures

[wujstefan]

Hello,
How high temperatures do you get on your CPU/GPU on idle/stress? I recently bought post-leasing T60p with T7200 + FireGL 5250 and it warms extremely fast, especially under the left hinge. 60C for CPU and 75 for GPU on idle isn't a bit too much?

[Harryc]

My T60P with the FireGL 5250 runs it's CPU (T7600 @ 2.33GHz) at idle @ 47*C. I've never seen it go above 70*C under load. If you can suggest a program to try to load it up I will do that and report results. GPU temps around 65*C at idle are normal for this GPU. 75*C at idle for the GPU tells me that your fan/heatsink is dirty or defective, or it is not making proper contact with the GPU, or that your room temperature is very warm.

Your idle temperature is 10 deg. higher than usual. Which software do you use to measure the temperature?

[wujstefan]

If you could check your temperatures on stress using 4e Everest I would be more than grateful.

I will try using some vaseline oil on fans + applicating some Actic Silver on CPU/GPU. Hope it will help.

My T60p 2007-AD1 (T2600 + V5200) idle temperature reading by TPFanControl 0.61: CPU: 48-52 C, GPU: 60-65 C, Fan speed is level 1 (~ 2800 rpm) or sometimes off, ambient temperature 25-28C.

[Harryc]

I'm not sure which version is Everest 4e, but I ran the Everest CPU Stress test and the temperature topped out at 85*c and stayed there. I would consider that to be worst case scenario since both cores appeared to be pegged at 100%.

[ssd_thinkpad]

My T60 runs for years at 75-80 celsius (without fan) without any problems in docking station.

[mpcook]

My T60p is running around 70 - 75 C at the GPU per TPFancontrol when under moderate use. The fan is a touch noisy, I may decide to replace it.

Well, used a vacuum cleaner on my notebook (without disassembling it) and.... temperature dropped to 65C (CPU) and 71C (GPU) at stress!
Idle adequately 51C/67C.

Silly thing, really

[RealBlackStuff]

Not silly at all.
You need to clean the fan every 6 months or so.
You only need to take off the keyboard.
Get a can of compressed air and use e toothpick or similar to stop the fan from spinning.
Give it a good blast, you'd be surprised at the dust that collects there.

[J888www]

Question: Do you really want to restrict the performance of your system by under-clocking? On the contray, I wish it to perform to the max........

Firstly, over time the Fan will suffer from wear and tear, please note it may not be necessary to replace the fan, it can be serviced. remove the fan and use 1 small drop of high grade machine oil to the centre spindle.
I used 10W Nano-Oil from Chriatian StClaire, I prefer to use the best but "sowing machine" oil will suffice. After reassembling the fan, you may find it runs smoother/quieter/faster, subsequently helping to dissipate a little more heat and reduce noise.

Secondly, over time the Thermal Pads which transfer the heat will deteriorate and may need to be replaced, but if you prefer to optimize heat transfer, do not replace these two Pads, use Copper Shim to plug the small gap and use a high grade Thermal Paste (on both sides of the Shim).
I used only ONE 12mm x 12mm x 0.8mm Copper Shim (can be purchased from eBay) and left the CPU and GPU dies bare (no Shim).
Thermal Paste was Shin-Etsu X23-7783D, note that not all Thermal Pastes from this same company are equally as good, be specific to the item number.

Link to Copper Shim mod, in theory it is the same, to increase transfer of heat away from the processors :-

I find it best to use the "pea" Thermal Compound application after warming the tube of Thermal Paste ib hot water for afew minutes.

This worked for me, but there are many factors which may determine it will not work, ie: correct application of thermal paste : too much gap between the GPU die and Thermal Heatsink etc.

Previously, I too had "lock ups" due to over heating issues, now stable. My modified T60p Core 2 Duo T7600, 120GB SSD, 4GB RAM (2x2GB), FireGL v5200, Win 7 64bit performs demurely but at a blistering pace.

I have Core Temp readings of........ Core #0 40 degrees & Core #1 41 degrees on 0% load.
........Core #0 83 degrees & Core #1 84 degrees on 100% load using Prime95.

[Harryc]

I used only ONE 12mm x 12mm x 0.8mm Copper Shim (can be purchased from eBay) and left the CPU and GPU dies bare (no Shim).

Where did you put this one shim?

[Rossano]

Hi all.

I have similar problem - my GPU is overheating. CPU temperature is satisfactory (75°C max. under load), but I worry about the GPU:

Calm state: 60 - 70°C.
Under load state: 80 - 90°C.
Under load in warm room: to 97°C.

Are these temperatures OK? I think these are too high, especially the last one. IMHO working at 97°C half a day every day could cause damage to GPU, eventually to the mainboard. What could I do? Take frozen accu-block under notebook?

[ThinkPadophile]

The GPU overheating problem is incredibly easy to fix, and J888www is spot on: simply replace the thermal cooling pad with a metal shim. It takes all of 5-10 minutes to accomplish, is easy, and makes a HUGE difference in GPU temps. I've modded several (including my signature machine) and this simple mod lowers GPU temps by 40F, at idle and under load.

[Rossano]

Oh, I've overlooked that. Sorry.

Well, now I need that copper shim. On ebay is rich offer, but I don't have an account there and in the Czech republic is nothing like ebay, therefore nor copper shim. I'll try to get that somewhere else...

BUT I have a question: How holds the metal shim on the GPU? If my T60p falls down from table, will the metal shim stay on the right place

[goofyGAguy]

Once the fan/heatsink assembly is tightened down, the shim isn't going anywhere.

[pit1337]

It must be between heatsink and die, so it can't move itself in any conditions.

EDIT: Looks like goofyGAguy was faster

[ThinkPadophile]

GoofyGAguy and Pit1337 are both correct. The shim replaces the thermal cooling pad and is held in place by pressure supplied by the heat sink, as well as by the thermal compound (arctic Silver 5 or equivalent) applied to both surfaces of the shim.

You can buy the shim over eBay, or make it yourself fairly easily. I made my own using a 1mm thick sheet of bronze I purchased at a hardware store for $4.00. I simply cut off a small piece using a hacksaw, filed off the burrs, and it was done.

[Rossano]

Thank you all for those valuable advices!

I've just disassembled the fan assembly and discovered the strange spongy material above the GPU (= thermal cooling pad). If the metal shim is more effective than the thermal cooling pad, I'll buy one. There is a metal-sheet seller near me, so I'm gonna to buy 0,8 or 1 mm thick plate of copper (or bronze) and install as said there.

Thank you guys once again! The best ThinkPad professionals are THERE.

[RealBlackStuff]

Copper is a better heat conductor than bronze.

[ThinkPadophile]

True, but both are significantly better than the thermal conductive pad. I believe that bronze transfers heat about 100X as well as the pad, and copper about 200X.

Idle adequately 51C/67C.

Silly thing, really

Did you just use 'suction' from the outside where the vents & grills are? or did you use blower in some way? Thoughts? Advise?

[crashnburn]

I am very tempted to go down this path.

I am not in the US right now, so shopping from the usual sites is gonna be tough. But I have a friend coming down, so I could have him bring it.

Which is the best thermal paste to buy? How many days will it take to deliver?

If he is not able to bring it whats a good Ebay option that I can buy & have shipped straight from Hong Kong / China?

Just make sure your machine is *OFF* and no power is attached, battery out, etc. I broke my first fan by using a vacuum cleaner while the ThinkPad was still on.

[Cbyron]

I am so glad to find this website, it seems a lot of experts here.
I have been struggling with T60P(mine is T7600, V5250, 2007-8ju)'s high GPU temperature for a while, I have taken the heat sink for multiple times, tried different ways except putting the Cu sheet in between.

Tried to remove the pads for GPU and northbrige from the heat sink, and also bend the heat sink a little, the results was '' CPU was able to be cool as 45C, while the GPU was more than 78C when idle.''
Tried to reuse those 2 pads and apply the thermal compound onto the GPU/northbridge/CPU for lots of time, the best temperature I can get is ''CPU 53C, GPU 69C.'' when idle, Evertest stablablity test, CPU fully loaded, CPU 75C, GPU 74C.''

One questions are putting the Cu sheet between the heat sink and GPU, by putting hard stuff onto GPU and giving a lot of pressures down to it, will it cause the damage to GPU? Another questio0n are if the temperature I have now can be considered ''normal'' level? Do I need to go for ''Penny mod''?

I love my T60P machine.

[ssd_thinkpad]

A temperature for around 80 celsius should not worry you. I have it at this level for some years and my T60 is still running strong. Of course it may hurt your notebook life time but in a few years your thinkpad is not worth so much anyway.

Thanks for your comment''SSD_Thinkpad''!

Perhaps you are right, running at this level should have no harm to the computer. I am a little paronoid about the temperature now, I have spent long time to try to lower it down. I did lots of experiments on different thermal compound. I will be glad to see it work.

[sentabrina]

I am here with the solution for T60p CPU/GPU Temperature issues.

Specifications:
CPU - T7600 2.33GHz
GPU - FireGL V5250

My problem was similar to everybody's else here in this topic.
I have had high idle temperatures

On AC adapter - Maximum Peformance >< RPM ~ 3500 (MAX, Noisy)
CPU ~~ idle 60 C, minimum 57 C
GPU ~~ idle 76 C, minimum 74 C

On Battery - Maximum Battery Life >< RPM ~ 3000 (Average, does not disturb me)
CPU ~~ idle 58 C, minimum 55 C
GPU ~~ idle 75 C, minimum 73 C

and I could not get rid of it, even with absolutely no dust in the heatsink.

Today I have found the related topic where one guy tels about the assembly problems in Lenovo, which resulted in far too much thermal paste being applied to the cpu and heatsink (this problem was covered under the waranty actually, nice?!).


When I first time disassembled the heatsink I cutted the square in the thermal pad over the GPU. Rest of the thermal pad is cooling VRAM so I left it there. And that was a GOOD idea!
Cut the thermal pad over the GPU (do not take it off completely)

I was also using too much thermal paste, which is criticaly BAD idea (now I know it...)
Later I cleaned both processor units and aplied just a half milimeter thin layer of thermal compound
Spread a very very thin layer of your compound all over the surface of the CPU and GPU. between 0.5mm and 1mm will be ideal!!

If you are a supergeek, try to practise screwing four screws of your heatsink with both hands simultaneously (like the assembly line ). It actually helps to spread the thermal paste over the processing unit.

Now here are the results I achieved:

AC Adapter - Maximum Performance >< RPM ~ 2800 (Average, almost nothing to hear), after some processor load RPM ~3400 (Noisy)
CPU ~~ idle 48 C, minimum 46 C, maximum 52 C (typing & internet browsing)
GPU ~~ idle 65 C, minimum 63 C, maximum 70 C

On Battery - Maximum Battery Life >< RPM ~ 0
CPU ~~ idle 46 C, minimum 43 C, maximum 49 C (typing & internet browsing)
GPU ~~ idle 63 C, minimum 59 C, maximum 65 C

Intel Burn Test v2.54 - Maximum Stress Level
Max temperature of CPU raised to 96 C (both cores - max 92 C), RPM ~ 4500 Cooled Down to 51 C in 6 minutes with RPM ~ 3400

Intel Burn Test v2.54 - Extreme Stress Mode
Max temperature of CPU raised to 95 C (both cores - max 91 C), RPM ~ 4500 Cooled Down to 51 C in 10 minutes with RPM ~ 3500

GPU Burn In Test with FurMark 1.9.2
15 Minutes of torture with 1600x1200 max fps 3 - 94 C, RPM ~3500
15 Minutes of torture with 1280x1024 max fps 5 - 94 C, RPM ~3500
Cooled down to 73 in 5 mins (I was bored of waiting longer... I prooved my point)

So the final checksum:
7 years old T60p with its original Heatsink and Fan works like a charm if apply a little ammount of thermal paste.
I used IC Diamond thermal compound.
Cheers

[Cigarguy]

Yes properly reapplying thermal paste and dusting out the dust bunnies can make a big difference. After a few years thermal paste dries up and no longer function as it should.

[lab]

I took a different path and replaced the v5200 motherboard with an integrated graphics motherboard, tweaked bios for fan speeds 1600-2000-3000rpm and replaced HD with a SSD. I also undervolted CPU and runs it 10x instead of 13x. Max temp I get with 100% CPU load for several hours is 55 Celsius and fan never runs above 2000 rpm which is (almost) silent even in a very quiet room. 1600 rpm which is normal rpm is silent enough to here the SSD under load.
