T43(p) heat problems

[jeffman12]

Just want to see how many people are having heat problems with their T43(p). I am looking at getting a T43p or T42p for university and I want to see how many T43(p) users are having heat problems.

[jeffman12]

Maybe people could post replies with their average temp and fan speed

[roast]

I voted for yes.

With dynamic switching, average idle temp is 44-50. Average load temp 44-60 (because of dynamic switching). Average heavy load temp, much higher.

Fan speed... uumm... how do you find this out?

[BillMorrow]

before voting, define what constitutes a "heat problem"..

how does the average user know a problem exists..?
i.e. what are the symptoms..

I would think a CPU temp of above 55C is a heat problem while using the laptop moderately.

What are some average temps of T42(p) laptops? How much hotter are the T43(p)'s?

[Greg Gebhardt]

I would say the average person does not even know what tjier CPU temp is and could care less as long as thier unit keeps running or does not catch fire!

What is your average temp? Do you find the fan on your T43p noisy?

[roast]

I currently define "heat problem" as "the unit not correctly compensating for its inherit ability of exploding/overheating" (which is true, as entropy dictates integrated circuits prefer to smoke). If the unit is too hot, then, yes, it has a heat problem. If the unit's fan is coming on at too low a temperature, then, yes, it has a heat problem.

I have no idea what my CPU temp is. My T43 is VERY simular to my T42p which was a cool. Most of my laptop use is with my laptop really sitting in my lap while in my lazyboy. The T42 was the very first laptop that I could use for hours without getting so hot that I could no longer stand it. I have only had my T43 for a few weeks but find it but only slightly warm on the bottom after hours of use.

As I have said in previous posts I can hear my fan rev up to top speed when first booted and they nothing. I do have the TV going but even when the room is quiet, I can barely if at all hear my fan running. It does slightly speed up when I am doing some heavy duty batch files conversions in PhotoShop but this is both CPU and hard drive intensive. This even causes my twin Xeon HP8200 work station to rev it's fan.

Unless I got a "special" T43, what I hear is just not a problem. I find my t43 to be very close to my T42 except the 43 is a little faster but not hotter or more noisey.

I have heard that this can be bad for your sperm count. Even a moderate temperature increase for relatively short periods of time can do long term damage to the little guys.

P.S. I'm making an assumption here that with the name Greg you are male.

[Greg Gebhardt]

You will have to tell my wife and 4 kids that my sperm count was low. As I want no more kids this all sounds interesting! <vbg>

I am assuming you mean faster as in performance? What CPU is in your T42?

Don't know it was the t42pKXU model. My t43 is not that much faster, I just trade up every year. They both have the same 15" screen. The T43 is a bit faster from what I can detect.

I don't run tests to see how hot I can get my CPU. I simply use my laptop and enjoy being able to be anywhere in the house or office when I do.

[felipeudel]

How can you find the temperature of the CPU?

[sugo]

You use free utility mobilemeter to get cpu/ACPI temperature.

[nrj45]

I have the same temps as roast.

The fan is always on. But why the heck is this fan running constantly ? At this time, my t43p is at 44°C (also dynamic switching/web surfing/25°C ambiant temp). But the air blown by the fan is not hot at all. my old acer begin to fan at 57°C !!!

Another point : I tried some games and the cpu temp raised til 62°C, but the fan was not spinning very faster than when idle.

I found that my t43p fan begin to blow at 42°C

[jeffman12]

Thanks for everyones input. I think I am going to go with a T42p so I do not have to deal with any heat/noise issues.

I am looking at this T42p right now

All those highest end module IBM is selling is definitely over-priced.
For example, from the same store jeffman12 is looking at the P2U:

2373P2U -> 2.1G, 1G -> $2999
2373KUU -> 2.0G, 512M -> $2595 (you can get it $2483 from other store)
2373GVU -> 1.8G, 512M -> $2230

(everything else is the same)

A retail box of Pentium M 765 (2.1G) costs $550
A retail box of Pentium M 755 (2.0G) costs $430
A retail box of Pentium M 745 (1.8G) costs $260

1G kingston memory is about $120


First of all, is it really worth the difference of $2999 - $2230 by going from 1.8G to 2.1G?


Second, if I buy a 2373GVU + Pentium M 765 retail box (to replace the 745) + 1G memory = $2230 + $550 + $120 = $2900

And I can sell the Pentium M 745 for about $200, and the memory for about $50. So my total cost will be $2900 - $250 = $2650

Um....just curious.....

[JHaislet]

I'm not sure how picky IBM/Lenovo would be on warranty work if you had to send your TP in with completely different ram & cpu. They might get suspicious if your TP shows up without a CPU or the not spec'd cpu.

Just something to think about.

[felipeudel]

odyssius, I also don't think IBM would warranty your system if you change the CPUs. My personal opnion is that it is nice to have the 2GHZ CPU but not much difference from the 1.86GHZ. The difference in speed will be "7%" which for human perception is nothing, while the difference in price is 20%+.
