hi there,

i just added a 2nd level till 51C as long as i realiezed that BIOS was going on a lower fan speed than fan control!

so what i use is

47°C -> 0, 49°C -> 2, 51°C -> 3, 55°C -> 4, 60°C -> 7, 70°C -> 0x80

CPU 50°C (0x78)
APS 47°C (0x79)
PCM 49°C (0x7a)
GPU 42°C (0x7b)
BAT 37°C (0x7c)
BAT 35°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)

my cpu is anyway going between 48-51 on AC level. for battery use i run the NHC

hope it helped any X40 users!

Hi guys! First of all, cheers to Shimodax for the great utility. I didnt notice it would make such a difference. Id like to post some of my settings for the fan utility and RMClock - as RMClock works seamlessly with the utility.

T43 2668 1.86 GHz 1 GB RAM X300 GPU

RMClock settings.
Using PST.
6X .700
8X .764
9X .796
10X .860
11X .940
12X .972
13X 1.004
14X 1.036

I dont have ODCM enabled only because it doesnt prove to be effecient. Maybe the throttling mechanism isnt as good as NHC - I notice that under Minimum 50% load the processor heats up quicker. Anyway.

Ac Profile Auto
Ac Mode Performance Level 4
Batt Profile Minimal (Only use first multiplier and voltage)
Batt Mode Power Save 4
On Suspend Force Maximal State.

Fan Utility.

Active set to 2 (Smart mode)
Cycle set to 5
MinimizeToSysTray set to 1
MinimizeOnClose set to 0
StartMinimized set to 1
Temps threshold colors - choose what you want - mine set to 47 50 53 (dont want it too hot before Bios kicks in.)
Beep Frequency 20 10
ReadErrors whatever you want
No Sensors Ignored

Now the fan settings. My T43 runs cool most of the time. My CPU speed never goes over 50 unless something demanding comes up (Games so on).
Level 37 0
Level 41 1
Level 44 2
Level 47 3
Level 50 6
Level 53 128 (BIOS)

These settings work well with both AC and Batt Power. I only hear the fan when it needs to be on (During demandning situations.) Otherwise my temps hover at 36-40 CPU and 40-44 GPU.

I know my schemes may look strange, however, I wanted this program to run at startup, and run all the time. Im not sure if this has been posted already but here is how I made it run at startup.

Scheduled fancontrol.exe as a task to start at logon. I disabled the "Dont start if comp rins on batt", "Stop the task if batt mode begins" options and Voila! it runs on startup. I wished it ran as a service though.

I should note that im not responsible for anyone elses setup. Dont blame me if you fry your comp. I dont think it will happen however - as I never reach temps over 52 c. (So Far).

Cheers,
Brian.

My T43 has a 2200BG, and its consistently the hottest component in the system by 10 degrees. It sits between 45-51 degrees. Does someone with the IBM Atheros chipset or the 2915ABG card have any data on the temperature? If it will shut my fan up, I'd be willing to fork up the cash for the IBM card or the updated Intel.

The day I got my T43 I was pretty much dumbstruck by the constant turbine howl, until I found the fancontrol utility. The machine would have been returned otherwise...


I've set the fan to come on at 54 degrees Celsius, which means it is never running. When gaming, I turn fancontrol off anyway. During normal use (fan always off), the temperatures are hovering around 50 degrees:

CPU 48°C (0x78)
APS 50°C (0x79)
PCM 43°C (0x7a)
GPU 51°C (0x7b)
BAT 36°C (0x7c)
BAT 31°C (0x7e)
BUS 47°C (0xc0)
PCI 51°C (0xc1)
PWR 50°C (0xc2)
This is with dynamic switching on CPU (700Mhz-2Ghz), and undervolted with NHC to 0.7/1.1 volts. X300 GPU on Powerplay (I tested actively underclocking it with NHC, but that is not the way to go. Powerplay is more efficient, as I've heard it also lowers the voltage, not just the frequency)

Levels=: 50°C -> 0, 54°C -> 2, 56°C -> 4, 58°C -> 7, 60°C -> 0x80


Now, if there was a way of making the 80GB Toshiba drive a bit more silent as well, I would be the happiest camper ever.

Hello,

my settings are as follows:

Level=48 0
Level=53 1
Level=57 2
Level=59 4
Level=63 7
Level=68 128

and the sensors read at the moment:

CPU 36°C (0x78)
APS 50°C (0x79)
PCM 33°C (0x7a)
GPU 40°C (0x7b)
BAT 32°C (0x7c)
BAT 29°C (0x7e)
BUS 38°C (0xc0)
PCI 40°C (0xc1)
PWR 45°C (0xc2)

Could another owner of a Z60m please confirm that APS shows the hottest temperatures most of the time?

I don't know why the APS runs this hot (usually 50-55°C), whereas T43s seem to run in the 40-45°C range. But maybe it's normal for the Z60m?

Thanks! AMS

I have g question,when start my T43(2668-44U),The system will say some error about winio,can not load winio.sys in app dictionary.but winio.sys file stay at app dictionary.

Anyone meet this error? give me some advice.

Hi all,

Just for your info:

Use the software on an X31 (1.4 GHz Centrino). My values:

Levels= 60°C -> 0, 68°C -> 1, 70°C -> 3, 72°C -> 6, 75°C -> 0x80

Temperatures are even lower than the bios' (72°C to switch the fan on; surprisingly these values are a lot higher than in a T42...), its just that the bios usually takes much longer to switch the fan off and rarely uses intensity 1 which makes the X31 noisier than it could be.

The hottest sensor is usually PCM. If the battery is loading the system slowly oscillates between 60 and 68°C with my settings (fan on at 68, off at 60°C). If not, it stays quiet.

I'm using the "high battery performance" ("Hohe Akkuleistung") energy setting. Otherwise the system oscillates without loading the battery, too.

Regards R.

Wow 60'C?? Isn't that too hot?

I have Levels= 42ｰC -> 0, 49ｰC -> 1, 55ｰC -> 3, 70ｰC -> 6

See my latest edit - the bios switches the fan on at 72°C at the PCM sensor. The X31 seems to get very hot if you have it on your knees, indeed.

Question: Can anyone confirm this value with an x31? Might be I've got a "monday" bios...

Or the other way round: could it be that IBM uses way too conservative settings for other thinkpad models? Guess the components of the X31 are not more heat resistant than other model's components...

Anyone else noticed that time more than temperature seems to affect fan speed?

My T43 runs for about 6 hours on low fan, then kicks up to medium fan speed. Happens like clockwork every day, even when the machine's idle. As an experiment yesterday, when the bios-controlled fan speed went to medium, I used the utility to crank the fan speed up to full and let it run until all temperatures were back down to about as cool as they can get. I then returned fan control to bios and it still wanted to run on medium speed. So I restarted my machine and (with the same temperatures) the bios returned the fan to low speed.

All that makes me think that the time a machine has been running plays a part in the fan speed, otherwise a restart should not cause the bios to return the fan to a lower speed than before the restart (which takes all of 30 seconds). Alterntively, a restart resets some unknown sensor.

Here are my settings on my T23, after not doing much other than viewing a few web pages.

Fan: 0x80 / Highest: 64°C (64 54 42 n/a n/a n/a 30 n/a 0 0 0 0)

Is this normal for a T23? This was with a brand new fan.

On my T42 the GPU seems to be constantly the hottest sensor. I would like to try using Powerplay to cool it down - but the ATI driver does not allow to switch it on when on AC power. Is there a way to activate it (other than installing omegadrivers)?

Using the T4x Fan Control on my T23 yields these numbers:

Fan Setting:
----------------------------
0=fan off
1=1800-2313 rpm
2=2284-2431 rpm
3=4386-4992 rpm
4=4742-5011 rpm
5=4705-4869 rpm
6=4833-5029 rpm
7=4802-4912 rpm

A setting of 7 gives these numbers idling:

CPU 41°C (0x78)
APS 45°C (0x79)
PCM 43°C (0x7a)
BAT 26°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)
XC3 0°C (0xc3

While 6 gives these:

CPU 38°C (0x78)
APS 47°C (0x79)
PCM 47°C (0x7a)
BAT 26°C (0x7e)
BUS 0°C (0xc0)
PCI 0°C (0xc1)
PWR 0°C (0xc2)
XC3 0°C (0xc3

The T23 doesnt have monitoring probes in the Bus, PCI PWR or whatever XC3 is..

It's interesting to note that a fan setting of 6 is a little higher rpm than 7. Changing from 7 to 6 has a slight audible change too.
I am surprised tho that there is such a large rpm jump from 2 to 3, nothing in between 2400-4300 rpm, may be a bad harmonic range

Test bed is a 1.2Ghz T23, 2647-8RU (originally a 1.0Ghz -4MU), 512RAM, 40GB HD, CDRW/DVD.

Thanks for your work Shimodax!!

TJ(over in the t2x, T3x forum...)

This is Aeronautical/Aerospace Engineering talk.

Bad harmonic range? I don't know, it very well might be. There could be somre serious resonance excitation that could damage the fan in that RPM region. Imagine that, it spins, starts pulsing slowly and buzzing, then a blade seperates from the hub. Morbid, but kind of funny.

Actually, they have done tests like that with HDD platters and I have heard of CDs spinning, vibrating, then mechanically failing in an optical drive at high speeds.

Nice test bed by the way.

you've never seen the MythBusters episode where Adam and Jamie put CD's onto a router (woodworking powertool) to go after the myth that a disk, put into a CD drive shattered, killing some poor end-user(musta been someone with a bootleg copy of XP?

They load up the disk onto the router and hit the switch. Routers run upwards of 20,000 rpm and the disks shatter almost instantly..I think they did the same to some HD platters.

Everything has a bad harmonic range.. ever done the wine-dipped finger around the lip of a crystal glass to make it sing? If you do it long enuff and provide the proper pressure against the glass, it'll shatter.. Remember the windswept Tacoma-Narrows Bridge vidoe clip? Wind blowing across the suspension wires set up a vibration that made the bridge swing and fail.. always a kewl video.. I have one of a large Army helicopter that was idling in the wrong harmonic range and the rotor blades shattered.. Thats what brought down United ...hmm, cant rmember the flight number, the DC10 that lost its turbine wheel on the #2 engine, it shattered and severed all the hydraulic lines.. almost made it to Souix City, NE..

TJ

That video of the army chopper must be awesome; my Dad was an engineer for P&W back in the day, he worked on the F100 and the updates to the J58s. They did one test of a turbines resonance range, spun it up on a powered axial that was bolted to the shaft and all from another engine inside a fortified room (almost a bunker). After it was kept at the right point for awhile, it started to vibrate and then shudder, and finally the hubs split...sending the blades into the walls and embedding them in the bunker-grade steel-beam reinforced concrete about a foot or two in. Basically, anything that spins, vibrates to some extent.

I also have the video of the Tacoma-Narrows bridge as well; now that is a classic.

I just started using TP Fan Control (great utility, btw!), on an X31 and on an X60s. I confirm the hottest sensor on the X31 is 0x7a (marked as PCM): it's consistently 10-12 degrees hotter than CPU (0x78), APS (0x79) and GPU (0x7b). I don't think 0x7a is nearby the PCMCIA slot on the X31 (my PCMCIA slot is empty, and it's not particularly hot below it). FWIW, there's no 0x7a on the X60s... Just wondering what 0x7a is on the X31 and why it's so much hotter than anything else. I included IgnoreSensors=PCM in fancontrol.ini

Like you I'm puzzled by 0x7a, found on the X31, but not on the X60s. On the X31, it's the hottest sensor. I don't think it's related to the PCMCIA slot (on the X31, of course). When forcing the fan to run at level 7 for a minute or so, CPU/APS/GPU (0x78/0x79/0x7b) fall down, and so does the mysterious 7x0a, but the temperature difference between both groups remains more or less unchanged.
Thanks for a great utility! Dominique

These are the readings I'm getting on my T60
CP0 145°F (0x78)
HDD 105°F (0x79)
HDD 107°F (0x7a)
GPU 149°F (0x7b)

snB 132°F (0xc2)

Settings
Level=147 0
Level=152 1
Level=158 3
Level=163 6
Level=167 64

Pardon me for being a dweeb, but I haven't quite grasped what the user is supposed to do to tweak the settings. I have a T43 2668.

I've downloaded and run the settings. I've performed the preliminary tests and I see they work.
when I use bios controlled, I see 3937 RPM

CPU 46°C (0x78)
APS 46°C (0x79)
PCM 35°C (0x7a)
GPU 49°C (0x7b)
BAT 35°C (0x7c)
BAT 26°C (0x7e)
BUS 46°C (0xc0)
PCI 51°C (0xc1)
PWR 44°C (0xc2)

I see in the fancontrol.ini files I have these editable values:

Level=47 0
Level=50 3
Level=55 4
Level=60 7
Level=70 128

Frankly, I have no idea what they mean or how they should be edited. I get that the 1st number is probably a temperature, and I probably need to increase it. But what am I supposed to be looking for? Which of these levels (1-7) is the low noise level? What temperature level am I supposed to be watching out for?

(Btw, when I change the manual settings from 7 to 4 to 3, nothing happens, but when I set it to 2, there are dramatic differences. The fan goes to 3060 rpm. Which is good, but still not ideal.

Believe it or not, figuring out this fan thing is turning out to be really important. I am recording a podcast using this laptop, and although the usb adapter is supposed to block out ambient noise, apparently the humming of the fan is severely interfering with my recording.

(On a related note, are there any other system modifications I can make to to bring the fan noise down as low as possible? (i.e, in power mode, etc).
1. If I turned off the wifi adapter, would that really help?
2. If I reduced the brightness of the screen would that help?
At this point I'll try anything

Thanks for your help.

Dweeb nothing! We all had to figure it out . . . Of course, you might do well to check out some other people's findings, but in short, here's the deal:

Fancontrol is monitoring a bunch of temperature sensors located in different parts of your machine: CPU, GPU, BAT, PCI, etc. Fancontrol sets the fan speed according to the highest temperature it senses (you can dictate which sensors to monitor and which to ignore; ignore sensors with caution!). The 'Levels' (above) are set according to what speed you want your fan to run at certain temperatures. So if, for example, your PCI was reporting 51C (which is the highest temp reported in your post) your fan would run at Level 3 (given the settings above). If you didn't want your fan to run when a device was reporting a temperature of 51C you would modify the .ini file accordingly, e.g.:

Level=55 0
Level=57 4
Level=60 7
Level=70 128

That's a bit hot imho, but if you only do it for the short while that you're recording it might be OK. Of course, you might want to get your fan going at lower temps again when you're done recording (by modifying the .ini file).

If you really want to lower your temps, turn off / down everything you can--it all uses power, and using power creates heat! Some people here use NHC to undervolt / underclock to use even less power (and generate even less heat). Which, in turn, means the fan doesn't have to work as hard to keep things cool.

Hope that helps,

Paul

I can turn off wifi and that reduces PCI. The only thing that stays high and even possibly increases is GPU.

Are there any steps you can take to minimize GPU? I've already turned off wifi.

Shimodax says on another thread, "Personally I consider everything under 55°C quite safe ... but that just a humble opinion, I don't know where most of the sensors are and I don't know all the hardware specs. "

so if I set the next threshold
Level=55 3, then I'll be fine?

I'm going to test some more, but I need to keep the fan unpowered for about 60-90 minutes while I do audio recording. I'm currently testing how much the cpu and gpu are heated as a result of recording this sound and inputting it into my recording software.

(One thought is to record from battery power. I've set up a battery configuration, but I don't know if I did that right.

As I said, I think the real limiter for me is GPU. Anything to get that down a bit would help things considerably. (*****Expletives removed by Moderator*****, 12 hours ago, I didn't even dream a utility like this existed!

Another random thought: is there any other way I can cool the bottom (towels, third party devices, etc). The big thing is it can't make noise.

Well, with NHC you can throttle down ATI clock speed. This could help . . . but I'm not entirely sure. There's also ATI PowerPlay. Check out this thread: http://forum.thinkpads.com/viewtopic.php?t=16480, especially the posts from troubadix.

I HAVE a powerplay tab for my ati x300 mobility 256mb but am unsure whether ican improve over the settings. i've set everything for optimal battery life

i'm not at the point where I want to mod my oem driver. I have enough pain in my life

on my ati settings, any other options:

change hardware acceleration to None?
opengl and direct3d to something other than balanced?

another question: how long can you overheat something without doing permanent kind of damage?

I'm probably talking about GPU, not cpu or pci. are we talking minutes/hours/days/weeks?

Well, I think I'm out of my element . . . You may want to post on that other ATI thread and see what turns up. Sorry I couldn't help you more

Is fan control still an issue for the newer models, or did they engineer the technology to work around what the faithful have been experiencing?

Hi

Hardware:
T43p 2699 (2000MhZ)

I've got freezes and sometimes BSoD,
First i thought I've got a problem with RAM since i checked the temperature.

WOW A freeze on 79 c° CPU

Isn't it to much?
On Reboot the fan speeds a short time up then down, and stand on low speed and never change again.
I think the sensor is ok cause on idle it tell me low temperatur otherwise high.

On a long hard job ( compiling ) and since i use TPFanControl on level 7
stable temperature and no BSoD

FAN Speed 4512 RPM
cpu 67 c°
aps 47 c°
crd 35 c°
gpu 62 c°
bus 50 c°
pci 46 c°
pwr 52 c°

I try to help my self with a vacuum cleaner to get out the dust but no effect.
Any suggestions how to cool down the machine?

Cheers
