T43p fan vs T43 fan and heatsink

#1 Post by Hans Gruber » Mon Jul 13, 2015 9:23 am

I have not taken the time to replace the T43p fan yet or re-paste it as of yet. Is there a difference in heatsinks between the T43 and T43p. Obviously the T43 has integrated graphics vs. discrete graphics in the T43p.

I ask because I could swap the entire heatsink on my T43 to the T43p if that is possible. On the T410 series the fan swap is pretty simple. It does have some aluminum heavy duty foil that you have to bend and shape a bit when replacing the fan. I was reading the T42 fan thread and wondering if the fan is welded or soldered to the heatsink on the T43 or if it easily separates from the heatsink.

There is a difference. What makes your question a bit more difficult to answer is that there were two different heatsinks that shipped with Intel-based T43 units. While they're both "long" fans they look - and likely perform - differently.
I ask because I could swap the entire heatsink on my T43 to the T43p if that is possible.
You can, but I wouldn't. Most of the heat - especially on a somewhat cramped 14" system - comes from the GPU and none of these heatsinks were meant to cool V3200 in the first place.
I was reading the T42 fan thread and wondering if the fan is welded or soldered to the heatsink on the T43 or if it easily separates from the heatsink.
I always felt that swapping just the fan itself was a waste of my precious time, given that one can pick up a complete good M10 heatsink for $12 or so...your machine, your money, your call by all means.

The guy that I've gotten my last batch from doesn't seem to be offering any at the moment, but I'm fairly certain that I've bought some here in the past:

When running Super Pi my T43p 2.1ghz hits temps of 82-83C under heavy load at full speed. It's running on power at 71C right now. I just wanted to post my temps with the current fan and heatsink. The M10 should be here today or tomorrow. I have TPFanControl running.

On battery mode the temps drop down to 60-61C.

Any thoughts on those temperatures? The M10 should be here today or tomorrow. Will paste the CPU with Arctic Silver 5.

That's high. What's the GPU sensor reading in TPFC?

I think it was 55C for the GPU. As I said the fan is on it's last leg. I wanted to put out these numbers so I have a frame of reference once I put in the M10.

The CPU from a cold start without power supply, runs 55-58C on battery. My original 6 cell battery (Sanyo) has 100 charging cycles on it. It's a 6 cell and still holds a charge very well. It's still a green battery and then I have two 9 cell batteries. The GPU is running at 56C. The M10 should arrive today. Have to transfer the palm rest from my old T43 because this one has a couple of small cracks in it.

How much does it cost to convert the PATA to a full SATA I? Is there any good solution for the HDD or should I settle for this 80GB Seagate 7200rpm drive?

I got the M10 heatsink today. It appears that the existing heatsink is identical in my T43p. It's like a total Thinkpad teardown to get the heatsink out. How do I get the PCMCIA card slot out? I took a few picks of my T43p taken apart. I am confused because on my old T43 there is a copper conduction plate over what appears to be either the GPU or CPU. On the T43p it's exposed with no heat spreader or copper conduction plate connected to the M10. I will post some pics a bit later, I don't have time to upload them at the moment.

No it's not.

You don't have to. Keyboard>palmrest>little plate over the PCMCIA cage that is held by one screw>heatsink itself. Done.

That's the NorthBridge chip if I understand what you're saying correctly. Don't worry about it. However, make sure that the new heatsink sits flush and tight over both the CPU and the GPU.

George, I am trying to make it sound like it's surgery. Anyway, here is a pic. By the way, this is workbench #2. The Green processor chip, is that the northbridge or southbridge? To the right of the heatsink. Also from left corner, PCMCIA slot. I removed the screw but the back next to the Atheros PCI wifi card. Is there another screw in there?

You should be able to lift the gray bracket now - gently - and remove the heatsink. Sometimes it gets stuck to the CPU, GPU or both. Proceed with utmost care in order not to peel the GPU cover off. Not that it's the end of the world if you do.

The chip that you're referring to is the NorthBridge one.

I gotta get that PCMCIA slot removed because the grey bar runs underneath it. I removed the one screw but the back end is stuck. Why way do I pull it out? Under the GPU there is a massive amount of thermal paste.

No you don't.

If you've removed the screws from the heatsink itself, try lifting it gently by pushing a thin screwdriver under the area that covers the CPU. You should have enough "give" to pull it out without removing the bracket.

Black goop seeping around the GPU? You might have to scratch some of it - very carefully - with a very thin blade in order to start separating the heatsink.

Good luck.

I am not as detail oriented as a German born engineer but if you noticed my screws are organized in clear plastic containers. What is worse, I have an entire exacto knife set with close to a dozen blades.

There are 3 screws that hold the heatsink in place. Is the GPU simply bound by thermal paste or are there some screws holding it down? I will use the exacto knives to separate the GPU and not bother removing the far left bar and PCMCIA slot.

Take these out.

No screws. Paste only.

Sounds like a plan.

George, I am trying to be funny. Will update you on my progress but it looks like my T43p has an M10 in it. The screws to the left of the T43p behind a bit are the 3 screws plus a few others. I will probably have to download the HMM file to put the thing back together correctly.

Not from the factory. And it seems like M24 to me judging by the picture.

Good to hear. The old one to the right is definitely an M24 which I really never liked. FRU 26R9074 or something along those lines.

Now run the machine for a few days and report back the temps.

Two beeps followed by a shutdown. I put the T43p back together and that is what I get. It attempts to enter bios but shuts down. Both under battery power and with AC power. What's wrong? I am going to take off the keyboard and make sure the fan starts spinning on the heat sink. I got a fan error message.

I took off the keyboard and palm rest to make sure the fan was plugged in correctly. Re seated the fan cable and got the fan error message. Will plug in the M24 fan to make certain everything works right.

Plugged in the M24 fan (it says M24 on a sticker) and the T43p powers up.

Here is my testing procedures to make certain the M10 fan was dead. I suspect the seller took it out of a system without testing the fan or replacing the fan itself before selling it.

That is a boot image of the M24 sitting on top of the M10. I always offers images whenever I have to return stuff on ebay.

The first one is M9 long fan used in some T40/p, T41 and T42 models with ATi 9000 graphics. It has weaker cooling properties than the M10 fan from the second listing.

Thanks George. Neither the M24 or the M10 cover the entire GPU with the heat sink. Is that because the ATI Mobility FireGL V3200 256MB is a massive and oversized GPU chip? It's like an aircraft carrier compared to the Pentium M.
