I have this Toshiba Tecra S1 model’s fan acting weird. The fan would come on when you turn on the laptop. Then it will stop spinning. I think it suppose to start spinning once the cpu is hot. The user complains that this laptop gets really hot and it just freeze.

1. Make sure the heat sink is clean and there is no dust inside.
2. Use new thermal grease.
3. Make sure the laptop runs the latest BIOS.

The fan starts up at boot time but when it gets in windows, the CPU fan stops, I don’t think its got anything to do with thermal grease as that only keeps the CPU cool. You can get thermal grease tube from any computer store for about $5. I’ve even tryed loading a ubuntu live CD and it does the same thing, the fan doesn’t seem to be working at all, any ideas?

Does your laptop shut down or freezes?
Take a look inside the heat sink, maybe it’s clogged with dust and the laptop overheats because of that.

The user complains that this laptop gets really hot and it just freeze. My first reaction is that the fan is not working. So I odered new fan and follow this website instructions to replace the old fan. I notice that the new fan would start up during boot up too…then stop spinning. I guess is that it will start spinning once the laptop cpu is hot. However, I do hear/feel the NEW fan spinning after using the laptop for awhile. Could there be other issues with the laptop for not detecting the over heating cpu?? I reused the old thermal grease. Should I use new one? Onche the cpu is hot, I notice that part of the fan is also hot, but i does not come on. If you havea any suggestions, that would be great. Where can I get thermal grease?

Thanks,

My cooling fan does not spin at boot up on my tecra 2100-does this mean I need a new coolin fan? it seems to be plugged in properly

I don’t remember off the top of my head if the cooling fan in Tecra 2100 starts spinning when you turn on the laptop. On some laptops it starts only when the CPU is getting hot.

the laptop keeps shutting off after 5 mins…so im thinking its overheating due to the fan not spinning

Does it feel hot on the bottom under the place where the cooling fan is located? If the laptop is hot and shuts down after 5 minutes but the cooling fan never starts, most likely it’s bad fan.

there is number, i don’t what is that: it is: PT831T-11Q4L.

This is not a US model, so I cannot find a list of part for your particular model, but I believe all Tecra S1 laptops are similar and you can use the same cooling fan across many different models. Here are part numbers for the fan assembly: V0000020030 or V0000020970. You can use either one.
Google the part number and you’ll find it.
