About hight temperatures on my T43

Hi!

I live in the caribbean, here the ambient temperatures are a bit hight the entire year (Yes, the entire year), like 33, 34 degrees C.

My T43 runs very hot (to me) always. Right now for example, these are the temperatures:

CPU 70°C (0x78)
APS 58°C (0x79)
PCM 43°C (0x7a)
GPU 69°C (0x7b)
BAT 42°C (0x7c)
BAT 32°C (0x7e)
BUS 58°C (0xc0)
PCI 59°C (0xc1)
PWR 57°C (0xc2)

The fan is running at 4657 RPM. My processor is a pentium-m 2.0 Ghz (with speed step enabled, artic silver 5, etc), the GPU is the radeon X300.

The area underneath the touchpad is VERY hot to the touch (I think that southbridge is to blame).

My question is: Can my thinkpad be damaged by those temperatures?? Is a very good machine, i don't want it to be damaged and im a bit worried.

These are the specs: Pentium-m 2.0 with artic silver, 2.0 Gb ram, 120 Gb hard disk, Intel 2915 wireless card, Radeon X300, Hydis 1400x1050 LCD, Bluetooth, 9 cell battery, NMB keyboard.

Thanks and sorry for my bad english.

That is hot, no questions asked. And you're obviously running TPFC...

My concern is CPU that gets hotter than GPU. Although nowhere near failing temps, I'd be looking at that fan/heatsink very carefully.

Do you have any warranty remaining with this machine?

i've wondered many times (actually every time i've openet a Txx series) - couldn't the heatpipe system get somehow punctured or broken?
in that case the temperatures would go up a lot...

Hi guys!

Im installing the service pack 1 of Visual studio 2008 and these are the temperatures:

CPU 83°C (0x78)
APS 62°C (0x79)
PCM 44°C (0x7a)
GPU 77°C (0x7b)
BAT 44°C (0x7c)
BAT 36°C (0x7e)
BUS 62°C (0xc0)
PCI 62°C (0xc1)
PWR 62°C (0xc2)

I can't understand why the hight gpu temperatures, since im not in any 3d environment, just firefox with 3 windows explorer windows, and the installer of Visual studio SP1.

These temperatures are just hight or are dangerous??

Once again, I don't like the CPU temp. Way too high. As for GPU, X300 tends to run a little hot.

Have you opened up the machine recently to blow out dust bunnies with compressed air?

Maybe re-apply AS?

Install long fan from T43p?

Sounds like a clogged heatsink, remove the fan and blast compressed air to the fan blades and heatpipes.

Hi!

I just put artic silver into the processor today. The system is idle now, and the processor is at 55C and GPU at 61C (running at 798.06Mhz). I checked the fan and is very clean and run at up to 4646 RPM.

What are the benefits of the T43P fan? Can i use it into this T43?

agarza · #8 Post by **agarza** » Wed Oct 01, 2008 4:12 pm

I recall there's this T43 fan that protrude to the northbridge chip, maybe it will be more efficient.

Are you using a thin layer of thermal compund applied ONLY over the CPU?

ajkula66 · #9 Post by **ajkula66** » Wed Oct 01, 2008 4:14 pm

Which version of TPFC are you running?

What temperatures do you get in the BIOS mode?

You should be able to use the M24 long fan on the standard ATi-powered T43, it extends cooling to the GPU and generally helps keep temperatures down.

Cyberstudio · #10 Post by **Cyberstudio** » Wed Oct 01, 2008 4:14 pm

Yes, a very thin layer just over the cpu. By the way, this is the "long" fan.

sparta.rising · #11 Post by **sparta.rising** » Wed Oct 01, 2008 4:21 pm

That's pretty hot. You can see my system in my signature, my GPU idles around 56-58oC, when I had an X300 it was lower, maybe 54-56oC IIRC, your idle CPU sounds fine. But your CPU under load sounds way too high, I usually don't see mine get above 65oC.

I'd agree about checking the fan assembly for a clog and trying BIOS mode. What surface is it resting on? A couch or a bed? What is the ambient (room) temperature?

edit: My "idle" temperatures are running Office and light browsing while running on AC.

Cyberstudio · #12 Post by **Cyberstudio** » Wed Oct 01, 2008 4:28 pm

The laptop is on a wood table. i never use it in the bed. Right now, the ambient temperature is 31C.

I don't think that this fan is in bad shape. Is very clean, no dust, and run at full speed. The cpu maximun speed is set to "Adaptive".

sjthinkpader · #13 Post by **sjthinkpader** » Wed Oct 01, 2008 7:04 pm

Set the power manager to "adaptive" instead of "maximum performance".

madkat · #14 Post by **madkat** » Thu Oct 02, 2008 1:33 am

even at maximum performance shouldn't run at 80+ degrees
my wife's T43 at full speed runs at maximum 75 (when the heatsink is clean, of course - and it gets cleaned every 6 months)

I'd put my money on heat conduction from the CPU to GPU (or vice-versa) via a poorly functioning heat sink.

madkat · #16 Post by **madkat** » Thu Oct 02, 2008 3:43 pm

exactly what i was saying several posts up - defective heatpipe...

@ Cyberstudio:

Did you see the thread T43 fan noise... really that bad? (and in particular the post by AdaSch of Sat May 31, 2008 5:58 pm), and note the result of the "thermal optimization" described there? That particular T43p ended having the following idle temperatures: 40 deg. C (CPU), 41 deg. C (GPU) etc., although in Poland during the spring/summer, with an assumed ambient temperature there of 20-25 deg. C.

If you add, say, 10 deg. C to those idle temperatures (because of your higher ambient temp.), you would still end up way below the temperatures you describe!

how can i know if the heat sink is poorly functioning? or if this headpipe is defective?

The heat sink is very clean, and the fan runs at 4600rpm (fancontrol says that).

I will remove the thermal X300 thermal pad and will put Artic silver 5. Will post the results.

Cyberstudio · #19 Post by **Cyberstudio** » Fri Oct 03, 2008 8:39 pm

Hi guys. I just removed the thermal pad from the X300 and put artic silver on it.

I also cleaned the heat sink a pen eraser and set the heat sink screws a bit more tight.

These are now the new temps:

Ambient temperature is 28C

Idle CPU: 49C
Idle GPU: 63C

Now, im using OCCT to put stress into the processor and these are the temps:

CPU under stress: 75C
Idle GPU: 73C

As you know, the gpu and the cpu share the same heat sink. Now with the processor under stress the gpu is hotter because the heat sink is hotter.

Now, what do you think? Now is normal or is too hot anyway?

sparta.rising · #20 Post by **sparta.rising** » Fri Oct 03, 2008 9:00 pm

Pretty good, gpu is still a little hot. Check the ATI settings to see if the GPU is set to maximum performance or balanced. If you aren't gaming, no reason not keep it on balanced.

Cyberstudio · #21 Post by **Cyberstudio** » Fri Oct 03, 2008 9:50 pm

I don't use this laptop for gaming. My desktop is for that. This laptop is for programming and office tasks.

Power play is on balanced. what do you think if i put it on Optimal battery life?, it will affect the performance of windows? or videos? (I don't use dvds anyway, just mpeg videos and youtube)

why2kliu · #22 Post by **why2kliu** » Sat Oct 04, 2008 10:38 am

I duno what you guys are doing, but my T42 on max performance hits 55C at peak temperatures. Regular performance (20 windows in opera + digsby + thunderbird) is 38-45C. On battery is 37C flat.

You should try undervolting with notebook hardware control or RMClock. On top of that, clean out all the dust on your fan, as well as the exit vents near the keyboard.

Optimal battery life cuts your CPU power in similar ways as NHC and RMC, however the latter 2 options offer more control over voltages. Video quality is heavily degraded.

You've said it yourself: your machine is a T42. Temperature (and other) differences between T42 and T43 are HUGE.
