Lower the temperature of your X22 or X2x thinkpad Now W/PICS

[Pennstate]

. It you have an older X series TP, the chances are that the thermal paste on you TP is all dried out and the cpu is just being cooked. I've removed the old crusty yellow thermal compound and reapplied w/ Artic Silver.

OKAY, here is the procedure followed by pics.

1. Remove 3 screws from the base that holds the keyboard in place.
2. Remove the keyboard carefully. Unplug the keyboard cable.
3. Remove the 5 screws holding the heatsink/fan. (4 silvery + 1 black)
4. Remove the heatsink.
5. Carefully scrape off the old yellow, dried up and crusty thermal pad from the heatsink. A wide flathead screw driver does the job
6. Clean both the CPU and the heatsink with alcohol.
7. Use a "clean" eraser to remove the residual sticky stuff from both the cpu surface and the cpu. I used a Staedler eraser for the task.
8. Now, this step may or may not be necessary. There's a heat spreader on the top side of the heatsink fan. This piece of metal is very soft and I think it's pure silver.
9. Carefully remove the silver bar using a flat head screw driver. You will bend the bar during the process.
10. Clean the silicone based thermal compound from the bar and the groove that it fits in.

11. Apply Artic silver the CPU surface and the groove. You should really read up on applying artic silver on google. The key is not to use too much of it and spread it out evenly. I use a tiny plastic strip to apply the AS. As for the groove where the heat spreader fits, you don't have to be that careful.

12. Reassemble the heat spreader, heatsink/fan, keyboard.

13. Boot back up and enjoy.

So far from anectdotal experience, the bottom of the laptop takes longer to warm up and the temperature under heavy cpu load is noticebly lower. I have not used any programs to monitor the temperature; just my lap:)

Here are the pics, they might be in reverse order:

That's gotta suck...

Anyway, quick question: does the X2 series use a socketed motherboard, and if so, what socket?

I'm considering a CPU upgrade on the X21 I'm getting.

[MASS]

Pics ready, I am waiting unpatiently on them
I have also been wondering if I should go with AS on the CPU die.

UPDATED:

So nice, so nice... Very good illustrated I´m saving this webpage included the pictures.

IBM ThinkPad X22 2662-92G (Bought 2005-06-02)
Pentium III 800MHz | 128MB RAM (soon 640) | 12.1" XGA | HITACHI TRAVELSTAR 4K40 40GB 4200RPM (21dB) | Windows XP Pro

You know, I don't think you have to list your screen in that case - I think all X22s have the XGA screen.

I had to list my screen, because the X21 actually IS available with an SVGA screen (granted, not with that CPU, but...)

[MASS]

You are correct, I was abit of a copy cat of your sign, you got me

[bhtooefr]

I could tell

FWIW, I think you might be able to just change your HDD description to 4K40 (or Hitachi 4K40) - it's shorter, that's for sure.

Also, in case you want the colored IBM, here's the code:

Code: Select all

[color=red]I[/color][color=green]B[/color][color=blue]M[/color]

I didn't list my WiFi card - I may just do that...

That's gotta suck...

Anyway, quick question: does the X2 series use a socketed motherboard, and if so, what socket?

I'm considering a CPU upgrade on the X21 I'm getting.

No, the CPU in the X21 is NOT upgradable. It is soldered onto the motherboard.

[MASS]

Updated The color code exceeded the total amount, so I'll have to pass that.

Well about the Ultraport, the bluetooth sounds nice, if I get my hands on a cheap one.
I can get bluetooth in CF slot, but it would be cooler to have it on top of the screen , as long it is as good as a standard bluetooth dongle or card.

[bhtooefr]

Hmm... I didn't even think about CF...

Electric Dog Ventures, who is now out of business, made a CF-to-IR adaptor, called the PDA-IR.

If you're in the UK, http://www.laser.com/?page=shop/flypage&product_id=196 has it for "10.00 GBP (11.75 GBP inclusive of VAT)" It's missing the side panels, though, so it's a bare PCB - apparently they are the current manufacturers. Also, I don't know if it'll work on Win32/x86 - it may only work on WinCE/ARM.

Anybody have one, along with an X2* series, and if so, is anyone willing to try it? I don't live in the UK, so I can't get one.

This company got really nice verdict in a swedish test on their bluetooth CF card.

The only problem is that Bluetooth II is around the corner just waiting to be adopted as standard in Windows enviroment. Some Macintosh has allready adopted it, but hey, Mac has an much easier platform to adopt new technologies on, since the haven't like a billions different companys making the hardware etc.

But also, theires new tech. instantly flowing through. So I might just wait a little bit. I bought two USB cables for my phone. An Nokia 6630, one thing is missing on that thing and it's the IrDA. So I have one cable instantly connected to my Stationary computer and one in my laptop backpack.

Maximal transfer rates:
Bluetooth - 720 kbps
Bluetooth II - approx. 720 x 3 = 2,160 Mbps and just half the battery eating.)
Nokia DKU-2 (USB cable) - 1.8 Mbps
IrDA - 4 Mbps
(Wireless USB) - probably 480 Mbps

GSM "GPRS" - 56 kbps
GSM "EDGE" - 210 kbps
WCDMA - 384 kbps
(WCMCA - 1.8 Mbps upcomming update in 6-12 month time in Sweden)
("Super" WCDMA - 100 Mbps in the horizont, first would be 3,4 Mbps or 10 Mbps or something)
(Wimax) - 15 Mbps testing in Sweden, it's like W-LAN with mobilephone tech. (roaming between antennas, every antenna approx range 4000 meter)
802.11b - 11 Mbps
802.11g - 54 Mbps
802.11g "Turbo" - 108 Mbit

ps. I'm writing little about what's happen in Sweden, and little of our available stuff. Also upcomming stuff here, Things not actually released, not available to all or is testing, I have marked with "()", cus I'm from Sweden, if you not allready figured that out yet

[bhtooefr]

I'm not interested in BT, seeing as the only thing I would connect is a Nokia 6225, and it's got IR, not BT.

I can get a cheap USB IR dongle for cheaper than a knockoff CA-42, the cable recommended for my phone, FWIW.

WARNING !!!
Just apply AS on CPU die and heatspreader won't simply do it, the problem is that the CPU die and hatspreader has a huge space between them, a simply used the AS on both and put the original "silver shinying" piece between them.

[Pennstate]

Hmm, I didn't put the silver piece back on. THe idle CPU temp is ~51C. What;s your idle cpu temp? I used SpeedFan for measuring the temp.


I'll put some layers of aluminum foil in between that to test the difference.

[MASS]

Yeaaahhhh... I kill the the fan, the fan died haha, jesus chriest !!!

Then I must buy the hole !"#)¤%=% over5 again, okey, I must have the X22 ?!?! I can't go with X20/X21 or X23/X24 fan ?!?! I see the part number is different.

[Pennstate]

I put a small square about 10 layers of Reynolds aluminum foil in between the CPU and the heatsink. It does seems to help with the temperature. SPeedfan reports 27C idle temperature???? But Mobmeter reports 48C. Which is accurate? Thanks a lot.

Also feeling the bottom of the laptop seems to be noticeably cooler

[MASS]

48 degrees is not accurate I tell you that for shure...

[roast]

Try mobilemeter or centrino hardware control (they're equivalent, so you just need to choose one).

[bhtooefr]

Grr... think I should do this cleaning? Read below (of course, I changed the image to a link before posting to keep the mods happy):

http://img267.echo.cx/my.php?image=cpuoverheat6li.png

My processor is running WAY too hot - it hit 92 C (94 C is the thermal throttling threshold, and 100 C is the kill everything now to keep the CPU from getting fried threshold).

The valleys in CPU speed are 500MHz, when SpeedStep was taking it down because I switched to battery. I've got it set to not fold when the battery's getting hit, FWIW.

I've set SpeedStep to run in battery mode even when it's plugged in. It's at least making temperatures manageable.

I may stop folding, though.

It runs a little cooler out of the UltraBase, but I'd like to keep it in there, and I'd also like to be able to run at 700MHz. The fan DOES seem to run - so it's not that.

It's dropped to 68 C at 500MHz in the UltraBase. Ambient is around 80 F in here, FWIW.

[bhtooefr]

It's holding between 70 C and 76 C when folding at 33% CPU utilization (at 700MHz), so I'll just stick with that.

[Pennstate]

bhtooefr, that's way too hot

[bhtooefr]

Ambient's around 80 F in here, and the CPU's running at 86-87C when folding all out, outside of the UltraBase (temps are 5-10C higher in the UltraBase).

The fan is DEFINITELY running, because I've put my ear up to it, and I've heard it (and felt a rush of hot air).

[bhtooefr]

Anybody know of a program that can monitor fan speeds on an X21 in Windows? I need to know how fast the thing's actually running. I can tell it's running, but if I can get it faster, that'd help my heat problems...

CHC can't read them... (it says it can only read them on a few models, none of which are made by IBM/Lenovo...)

[MASS]

Ok, Now it's time for copper some copper
0,2mm
0,3mm
0,5mm
or 1,0mm

http://www.clasohlson.se/images/product ... 171928.jpg

and fit it nicely with http://www.arcticsilver.com/arctic_silv ... hesive.htm

bring down the temperature dramastically, so I can sit in the warm sun without worry about CPU heating up.
