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 the cooling fan in your Tecra S1 started making noise, like in my case, 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.
OK, let’s move to the fan replacement guide.
First of all, remove two screws securing the fan cover and after that remove the cover.
Now carefully unplug fan cable from the motherboard. Loose four screws securing the heatsink.
Lift up and remove fan assembly.
You’ll see white stuff on the top of the CPU, it’s thermal grease. Thermal grease conducts heat from the CPU to the heatsink.
If thermal grease in your laptop dried out, you’ll have to replace it.
If thermal grease looks OK, you can reuse it.
It’s possible that you accidentally pulled the CPU from the socket while removing the cooling assembly. I would recommend reseating the CPU just in case. Unlock the socket with a flathead scredriver, make sure the CPU is seated properly and lock the socket.
On the picture below you can see the newer fan assembly on the left side and the old one on the right side, they are a little bit different. You can find and buy spare cooling fan assembly here.
I’m going to reuse the old thermal grease. On the picture below I’m collecting the old thermal grease. You can apply new thermal compound.
Reapply thermal grease on the top of the CPU.
When I was ready to install the new cooling assembly I noticed that my motherboard is missing HEX studs. They came out with the old heatsink. 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 fan cable to the motherboard.
The cooling fan has been replaced.

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.

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!

TechGuy,
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.

Damo,
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.

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?
