CF-C1 temperature?

hello,

Can someone help me, i have problem with my CF-C1 temperatures, or i think it should be lovered.

my CPU temp go as high as 88`C, i think its little to high. Works fine, dont slow down but it seems a bit high.

I saw one post but it cant coment anymore.
http://forum.notebookreview.com/threads/cf-c1-mk2-heatsink-cooling.816453/

it mentione gap between heasing and CPU should i put thermal pads in that place?

i use Arctic MX-4 paste and i dont think i get some difference.

first 30 sec when it boots it goes to 88C.
Correct me if im wrong.

 

88° C seems high to me.
The gap is probably too wide for paste to work. Try a proper thickness thermal pad.

 

Yeah it seems high to me too.

A check for codes from the chip that has biger gap and it turn out its north bridge chipset.

According to intel, this procesor has max temp 100°C and im not far from it and i dont like it.


Any suggestion? Advice?

 

Disassemble unit.
Remove mainboard and heatsinks.
Clean chips and heatsinks. Chipset and cpu.
Reassemble using proper size thermal pads.

 

Ill have to find 0.5mm thermal pads,

Unit was dissasambled and put new paste but nothing better than before.

Should i put pads on that place where is gap and on cpu regular thermal past or should i put both pads?

 

If there is a gap you need a pad.
Use pads only. Pads do not need paste
Paste only works for micro imperfections Paste will not work alone to fill a gap.

 

You can use a shim made out of copper if there is a huge gap and or tweak the cooler so it sits flush on the cpu.
I been using a laptop cooler for a cf-c2, it made a huge difference. Its gets hot enough to burn you lol and now its cool to the touch.
Side note... I took apart a cf-t8 this week and the thermal paste or pad was just basically dust. Looking for a service manual for that old model if anyone has? I changed the power led it was oddly burnt out.

Thanks
I try and collect the service manuals though for newer models. Most of the user manuals are still available from panasonic.jp

 

I did use it a few times,didnt have time to dissasemble it again. And it worked fine. Not more then 65°C,then today i use it and blue screen turn up.
With some code Bccode 48. Dont really know what that means but it sure isnt good.

 

Driver issue, what OS are you running?

 

In my experience CF-C1 just runs hot, it has very very small heatsink assembly for 25W TDP CPU. Running synthetic benchmarks it'll hit 95C straight away and throttle.
The gap you're mentioning is between heatsink and northbridge. From factory it's just filled with glob of thermal paste, not a pad. I used some high viscosity paste that is marketed as pad replacement there and mx-4 on cpu and it made no noticeable difference, temps and overheating stayed about the same so I guess this is how this machine is designed to run in the first place. If you're idling with no load at <54C and barely running fan you're ok.
Was using it for two years or so and recently motherboard died, it was just sitting on charger and wont turn on again.
While it looks cool and has superb touchpad it has severe design issues like thermal throttling, excessive usage of adhesives (nightmare to take apart), driver issues (wwan), subpar seals (dust between display layers) and so on.

 

I've been running all sorts of Toughbooks since 2006. I have had them so cold they need time to warm the hard drive before starting... But never had one so hot it would shut down... Which it will do if it sense heat that is too high. They are designed for that.

I have had different ones get hot if I were to have them on my lap where they don't get good airflow... But I generally use them now on a hard surface. If you have an older Toughbook it might be worthwhile checking the thermal pads for shrinkage or outright crumbling. Word has it that you should NOT use thermal paste (Instead of or in conjunction with) a genuine Toughbook thermal pad. I have used brand name thermal pads though and never had an issue yet.

 

I have never seen that on a unmolested Toughbook.

The CF 1's and CF 2's are a real challenge to tear down.

I agree with Toughbook. Only overheating was when I blocked the fan on a CF 52.
In my experience Panasonic never uses paste from the factory. Thermal pads only. I have changed them on the "arms" of the heatsink on a CF 31 that are thin as heavy paper. Then on the CPU they are 2mm or so. Paste is for minor imperfections not gap filling.

 

I missed that one Shawn... Agreed... Someone did that and it wasn't the factory. OP needs to get thermal pad installed if he wants to prolong the life of that Toughbook.

 

Honestly that looked really odd to me so I went looking at pics on internet mostly of heatsinks for sale that where not cleaned and it looks like mk1 uses thermal pad and mk2 uses blob. It would be really odd that so many machines had pads removed and replaced with paste and mine didn't look like it was ever opened. Maybe it's not regular paste, there are many low viscosity compounds that are marketed as pad replacement and supposedly help with preventing bga failures but it looked the same as stuff on cpu to me.

As for overheating, there are couple of cf-c1 reviews online and they mention throttling under stress which means cpu gets to 95C. Heatsink assembly is also miniature like something you would find on a atom netbook with 2w tdp cpu.

 

I've never had a CF-C1 open... But I have opened just about every other type. I've never seen Panasonic use paste. Now... I HAVE seen some thermal pads so distorted I could see why you might think that.

And don't fall for the "it didn't look like it had never been opened." Neither do the ones I work on when I finish. That's the whole point.

This is how it looked on mine. Maybe it was really a pad decade ago.

Maybe someone will needed it for proper cable routing and stuff like that, few pics from teardown:

Even if it was paste from the factory I would replace it with pads.

 

Replace that crap and work cooler!

 

Thanks for the helpful pics! I have several C1's that may need cracking open some day.

 

I know im almost half year late, but it was on hold.
its my working laptop and i cant let it get blue screen when i program ECU or keys.
I use it for automechanc testing and it has get beating, but since i bought it, it blow hot air from 5 sec after turning on,
but never had blue screen, honestly i never look at temps.
but its odd that it gets to 90C after few minutes of work. but no trottling. Speed is always ok.

You suggest that i use thermal pads on that gap and on CPU?
I have some ARCTIC Thermal pad APT2560, high performance gap filler, is on the box.

I really like my CFC1.



Thx in advance.

 

Been a long time since I worked on a C1.
Does it have a fan? I think it does. Verify that the fan is spinning.

 

I cannot say about the c1 but the c2, which i have has no fan. these models are low wattage cpu. I think it uses the case as heatsink like the c2. I have used artic silver many times though on cpu instead of the pads on several models. some HP though I used a copper shim since the gap was large. My c2 gets very hot that its hard to touch the bottom of it when playing a game. I got one of those laptop coolers that seem like a gimmick but it actually made a huge difference

 

I has fan,and fan spins at 100% when it is atound 87C .

I did put just arctic paste and it didnt helped maybe a little but. Sometimes it is around 65C and sometimes is around 85+ C

EDIT:
I did test one car outside after paste replace. Outside temperature was 5-7°C
And temp of CFC1 was 65C

But outside was cold.

 

If the gap is big you can use copper shim with artic silver. these machines run hot under load though. Mine will just about burn the skin when cpu at full. I would assume you cleaned the vents etc also. Maybe a laptop cooler that can suck the heat out of the vent might help. Temp here is 33C

 

From the photo in this thread, it appears that paste was used on one chip and a pad on the other.

Disassemble laptop.
Remove thermal paste.
Install proper thermal pad.
Re assemble laptop.
Enjoy computing again.

 

I clean all the dust from it, wasnt too dusty.

I also tought i can do past on cpu side.
And thermat pad on gpu side at least i think its gpu.

Here is youtube link. Sry for bad quality i was at work.
This is on idle, no programs were started.
Temperature is wild.


From time to time it gets some wierd noise, like buzzing electrical noise. Its hard to explaing and i cant record it. It is t loud enough for clear playback.


EDIT:
i found some photos when i dissasemble it.

 

this can be software issue that is making the cpu run at 100. I have seen it before. What program are you running for automotive? I will check the c2 this weekend for temps but very different cpu. i have the i5-4300 that is only 15w. you prob have the 2520m?

 

I hope it is software issue.
Im running ODIS, Vag com(vw group)
Multiecu scan for fiat.

And thats about it for the programs.

Is there anywhere i can download driver pack? I hear that its pain to install it, it has some instalation order and around 50 drivers

EDIT: you are right mine is i5-2520m and its rated at 35w TDP .
I dissable turbo and its a little cooler now.

 

The goal is to keep your cpu running slow. Those programs should not be cpu intensive i would think. Someone here might have achive enterprise pack for this laptop. I do have a cf-h2 which is similar specs to yours and I think i used the driver pack and whatever did not work i just did manually.

My toughts were the same about run it slower. Its noticable faster compare to my CF-52.
In few days ill catch time and dissasamble it, replace paste and put pads and hope for the best and without blue screen.

Thanks for advices.

 

My CF-19Mk5 is the same CPU and it runs very hot, I used it to run as a desktop for some time and 90c was not unusual. Windows 8 and 10 are famous for the 100% cpu, AV is the big offender along with windows search and superfetch. I have fixed a bunch of them. The CF-C1 doesn't cool well at it's best.

Having said all of that, the CF-19 runs at 60c with my daughter playing roblox.

 

The cooler is funny for 35W TDP id say.
Im running win 7, its pain to make other programs work in win 10 so i decide to go win 7,
its known how those programs that i need work in win 7 so its easier for me.

Yesturday was blue screen again, but its to fast to take a pictures and restarts after few sec.

 

I dissasemble it this evening. And this a the resaults...
As i see it now on the pictures....it looks ugly, looks less ugly on the crime scene.


Going to buy pads tomarrow.

 

This evening will be assembly

 

I test it and it said 43°C on idle, so i guess thermal pad 0.5mm, arctic thermal pad, and arctic mx5 paste did the trick. And i hope it will stay like that.

Dissable turbo. Its fast for car testing without turbo.

Ill keep inform after week or two. When i use it a little more.

 

Testi it for a while now, so far everthing seems to be as shuld be.
Sometimes temperatures spikes but not like before. usualy is around 75C
