Thanks everyone for your help with selecting the fans. I got hold of a M24 and put it in. A couple of questions came up: The heatsink does not have the rubber part between copper and GPU chip. Was that required? How fast is the temperature (CPU) supposed to rise while testing? I managed it to get up...

That's a M9 fan which will work, but has slightly weaker cooling properties. This is *the* proper fan: http://www.ebay.com/itm/Long-Fan-Heatsink-IBM-ThinkPad-T40-T41-T42-t42p-13R2657-/180968043262?pt=LH_DefaultDomain_0&hash=item2a228932fe Oh, another fan. I didn't know about the M9 until now. OK. S...

You can check here how long they need to ship the fan... Even cheaper than what I thought... The price is great. Looks like the wrong model though: the Hardware Manual distinguishes between the "Fan assembly (long)", P/N 13N5442, which is offered in your link, and the "Fan assembly (long) M10", P/N...

Given that these machines are prone to BGA failures of both GPU and SouthBridge areas, keeping them at a stable temperatures and properly ventilated is a must in my not-so-humble opinion. Do note that you can also utilize the M24 fan from T43/p, and these are even less expensive than the original M...

I had a fan issue two years ago and used my T42p for several months without a fan and as long as the room temp was not too high (it was mainly in summer) I could keep very acceptable temps, even though I think it was not a good thing for the mainboard. My humble opinion is that until you fix/replac...

I was keeping an eye on Ebay to get some extra fans just in case and they didn't seem expensive (around 25$), or rare. Have you checked the Marketplace here in the forum? OK, if you start keeping an eye out while your fan still works, then I'm sure you can pick up good deals. Good idea. Mine doesn'...

Thanks to everyone for the very helpful replies! Would you rather spend $20-30 on a heatsink assembly, or a $100+ on a good motherboard? If it was just a matter of spending $100 once in a lifetime, and then have a perfectly silent fanless machine, I'd certainly do it. But I don't think it will last ...

I'm also interested if you folks could tell me if it is feasible to just run a thinkpad without any working fan . While doing regular work on the thinkpad. For an extended period of time. Say with reduced speed. I have a 2.1GHz processor which is capable of running at 0.6GHz. So presumably things wo...

I have a T42p. For a while, I have been getting "Fan Error" messages at boot. Recently, the fan started making annoying noise. Now, it has stopped spinning altogether. What is the best way to proceed? Fan assemblies (long fan) are hard to obtain and expensive even on the 2nd hand market. Is it possi...

I never said anything about playing HD video in this thread, so while you might've been thinking about that , your post referred to playing DVDs which is a completely different ballgame... :roll: Exactly that was my mistake. Since I never play video DVDs, my fuzzy knowledge of them was limited to "...

So you guys can actually watch DVDs on your T42p. I am delighted to hear that, since I have a T42p also, and would love to learn how it is done. I never even tried DVDs since I use Linux and there is not much / any Linux software to play commercial DVDs, and more importantly because I thought (hopef...

i have never seen bad ram damage a thinkpad.. That is good :) ram can stand a lot of mis-handling I have read that it is very easy to bend its board. And that this can cause cracks in the chips (presumable even easier in the soldered parts, board wires and such). your mileage may vary.. I don't car...

If the machine is complete and works with no issues (make sure to watch a good portion of a DVD movie, go on youtube, do something graphic-intensive), $75 is a steal. How would you possibly watch a DVD movie on a T42p? They didn't have special video decoding hardware in the GPU in those days. The C...

FRU number? Manufacturer?

I bought some extra RAM recently (second hand) but the shipping box was very bad (just plain envelope) and without anti-static protection. Is there any danger in trying it out? If it is damaged, can it short circuit or otherwise damage my TP? Would you put it the TP in or rather not?
