How to replace fan in Toshiba Tecra S1

Cooling fan Tecra S1



In the following guide I explain how to replace the cooling fan in a Toshiba Tecra S1 laptop.

The fan is a part of the cooling assembly, it’s permanently attached to the heatsink. If it started making noise, you’ll have to replace the entire cooling assembly.

There are two different assemblies out there. The older assembly has part number V000020030 and newer one has part number V000020970. You can use either of them because they are interchangeable.

First of all, remove two screws securing the cover on the bottom remove it.

Now carefully unplug fan cable from the motherboard. Loose four screws securing the heatsink.

Lift up and remove the heat sink assembly from the motherboard.

You’ll see some white stuff on the top of the CPU, it’s thermal grease.

If thermal grease dried out, you’ll have to replace it. If it looks soft, you can reuse it.

It’s possible you can pull the CPU out of the socket while removing the heat sink. I recommend reseating it just in case. Unlock the socket with a flathead scredriver, make sure the processor is seated properly and lock the socket.

Remove old thermal grease

On the picture below you can see the newer heat sink assembly on the left side and the old one on the right side, they are a little bit different.

I’m going to reuse the thermal grease. On the picture below I’m collecting it from the old heat sink.

When I was ready to install the new cooling assembly back on the motherboard, I noticed that it’s missing HEX studs.

They came out with the old heat sink. I removed all four HEX studs from the old heatsink and installed them on the motherboard.

Finally, install the new fan assembly into the laptop. Do not forget to connect the cable to the motherboard.

    Parhat,

    I don’t have the fan but I can help you to find the part number for a new fan (if you have a US model) so you can research online. Give me the laptop model number, it’s on the same sticker with the serial number.

    Parhat,

    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.

  5. Hi
    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..thanks
    please email me

  6. also-(im sorry i forgot to add this)

    dee,

    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.

    HI there,

    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. 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,
    Guy

  10. Hi There I am having a similar problem with Techguy’s Issue, 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.

    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.

  14. Hi there!
    I have old Tecra S1 (2006 I think…)
    The cooling fan is very, VERY noisy lately. I am afraid it will stop working,
    and CPU will overheat…
    Can you help me where can I find the fan?
    This is the number from the back of my laptop.

    Serial # X3019080SU
    Part # PT831U-14E5T7X

    P.S. the “5” and the “S” are so similar that I hope I’ve read it right…

    Thank you in advance!

    shakir,

    First of all, test your laptop with an external monitor. If the external image has same problem, this is the video card failure.
    The video card cannot be replaced because it’s built into the motherboard.

  21. Dear Sir,

    I have a question about the Toshiba Tecra S1 Laptop…..can you please tell me where to find the CMOS Battery in this model? And how to exchange it?

    Thank you very much for your answer to my emailaddress,

    greetings from Germany,

    @ Ludwig,

    Visit irisvista.com/tech/ for disassembly guide.
    The SMOS battery shown on the step 12, it’s located on the lower side of the bottom cover. Do you see the green part on the bottom? This is the battery.
    In order to access it you’ll have to go though steps 1-12 and remove the palmrest assembly. Unplug the old CMOS battery from the motherboard and replace it with a new one.
