Temperature Problem T43

Message

Emilio · #1 Post by **Emilio** » Mon Mar 24, 2014 9:51 am

Hi all,
I have a big problem on my Ibm T43, normally the temperature of the Cpu is 90° C, more o less, and I have done some things, like clean the fun, the contact of the fan, grease (fat) in the fan, programs tpfancontrolsource_0_21, but always the same: someone can give info to resolve this problem?
Thank you very much and best regards.

Don't know what fat/grease you used and where you used it.
But there needs to be proper thermal paste (like AS5 = Arctic Silver 5) between CPU and cooler.
You apply this after cleaning both CPU and cooler with Isopropyl alcohol.

Hi RealBlackStuff,
I have also the Thermal Past, but the temperature is always the same. Do you have other thinks to do?
Thanks and regards.

Hi dogbarber,
yes grease (fat) in the fan, after no noise, but the temperature is alwaus too high: naturally the fun has to to be opened in the four points.
Regards.

Fans do NOT take grease or fat, only sewing machine oil or an even lighter oil!
I suggest you get another cooler, yours does not seem to be working.
Make sure to get the correct one (Intel and ATI graphics models use different coolers!).

Knowing what I know about oil and oil viscosity, I think your animal fat would be too thick to allow that tiny little fan to run efficiently off of the tiny little push it gets from the battery. RealBlackStuff is right, you need a super thin oil.

I'm a dog groomer by trade and the oil we use to lubricate our clipper blades would be perfect.

Dead animal goo may not be the best thing to use with such a finely tuned fan.

Hi guys,
yes, but the high temperature there was also before of the fat. I put fat for the noises and with fat no noise. Now I would like to resolve also the problem of high temperature. Can be normal this high temperature because I have put High Performance always?
Thanks and regards.

Hi Emilio!
Try to start your notebook with keyboard opened. Does the fan rotating? Also try to touch top copper side of cooler(if thermal grease good - 90C will be extremely hot to touch)

If the cooler turns out to be working as intended, then look at this:

Either your fan is no longer working, or you use the wrong fan, or it is not mounted properly with thermal paste.
Did you plug the power cable from the fan in the correct slot?

dogbarber · #13 Post by **dogbarber** » Sat Mar 29, 2014 3:48 pm

Or the fat has seized the fan.

I can't be believe that's even a sentence.

Emilio · #14 Post by **Emilio** » Sun Mar 30, 2014 11:47 am

Hi all,
today I have put a fan of another Ibm T43, not oped, not fan, original naturally used. The temperature is lower, but alwasy high between 80° and 90°. Now I don't know if the problem is only the fun, what do you think?
Thanks and regards.

I suspect that there's either too much/too little thermal paste applied or the heatsink is not sitting correctly.

The temps that you're reporting are pretty darn high even for a "p" setup.

Are you using ThinkPad Fan Control?

Emilio · #16 Post by **Emilio** » Sun Mar 30, 2014 1:59 pm

Hi ajkula66,
also for me the temperature is too high: yes I use tpfancontrolsource_0_21 with Setting Manual 7, is correct the setting?
Thanks and regards.

ajkula66 · #17 Post by **ajkula66** » Sun Mar 30, 2014 4:38 pm

Wow...if you're getting those temps with the fan on 7, there's something definitely wrong with the fitting of the heatsink.

What is the P/N or FRU number on that fan?
It's probably from a different/wrong laptop.

Emilio · #19 Post by **Emilio** » Mon Mar 31, 2014 2:55 am

Hi all,
the fan that I am using now with temperature lower but always between 80° and 90°, is 26R9066 Fru Fan Long M24 26R9074: on the other fan with temperature higher between 90° and 100° it is impossible read the number part. Please let me know.
Thanks and regards.

ajkula66 · #20 Post by **ajkula66** » Mon Mar 31, 2014 3:52 am

That is the correct fan for T43...you might have to re-fit it again.

Is it noisy? Does it seem to be spinning OK?

Emilio · #21 Post by **Emilio** » Mon Mar 31, 2014 4:01 am

Hi,
no noise.
Thanks and regards.

ajkula66 · #22 Post by **ajkula66** » Mon Mar 31, 2014 4:16 am

The only thing I can think of is that it needs re-fitting since it's not sitting properly.

Some XP machines suffer from a bug in windows update that puts the CPU under 100% load, stopping the associated service stops the problem.

To check if this might be the problem, open the task manager to see if the CPU is under load, if it is, try stopping the "automatic updates" service.

Hi all,
I don t know why, but from yesterday afternoon the pc is working with a normal temperature between 60° and 70°: I have not done nothing of different. I hope now that will continue to working with these temperatures.
Coul be do because I have turned heathin of in my home?
Thanks and regards.

Emilio · #25 Post by **Emilio** » Thu Apr 03, 2014 1:55 am

Hi all,
another time the temperature of the pc is very high, between 85 and 95 degree. I don t know.............. Help me.
Thanks and regards.

dogbarber · #26 Post by **dogbarber** » Thu Apr 03, 2014 7:19 am

I think we are all at a loss for advice at this point.

#27 Post by **RealBlackStuff** » Thu Apr 03, 2014 8:38 am

How about taking pictures of that fan, how it is mounted and whatever else info?
Post the pictures on imageshack, imgur, picasa, or wherever, and post the links, so we can see WHAT you are doing (wrong).

ajkula66 · #28 Post by **ajkula66** » Thu Apr 03, 2014 9:21 am

Solid advice right here:

and if that doesn't resolve anything, I'll just repeat myself:

Hi all,
I am very tired, one day the temperature is ok, and one day no ok. I have 3 Ibm T43 and I know like change the fun, so I dont think that is a problem of installation.
Thanks and regards.

I'd still check whether the heatsink pipes possibly got bent during installation, and that the heatsink itself is sitting properly.

Take it - or don't - from someone who has worked on more T43/p units than 99% of the mankind and still got the pipes messed up on a couple of occasions.

Good luck.
