Hello guys, i have a laptop (which already was in a topic in this forum like 2 years ago) and i would like to do something with it.

So i would like to get his fan to 100% all the time, i am a cooling maniac and i like to have everything as cool as possible and i think my laptop should not be an exception x)

I talked to my teacher and he said that i had 2 options:

1- I could update the bios to one that could have all the advanced settings that are not presented in my current one.

2- I could go Extreme and cut the yellow wire (the fan rpm sensor), but he said that it could be dangerous because he didn't knew how the motherboard could react by not knowing the speed of fan, he said that the fan could stop or it could go at full speed.


Now, I already updated my bios with no success (meaning that the bios I updated to does not show any setting I haven't seen yet) so the wire is the only thing left.

Does anyone know for sure motherboard behaviors on these kind of things? in my head I think that for security measures that the fan would go top speed but it also makes sense that it could stop or go to a lower voltage mode.

Any ideas??

Cheers

Why not get just a cooler for the notebook.

or

Seems easier than modding and maybe killing the notebook's fan

Besides can't you control the fan with programs like fanspeed?

I already have a notebook cooler fan and it works great, but i want some more, i already tested with almost every trusted software fan speed controllers out there, they can't detect it.

You are correct they wont detect it nor will any app give you control of it. And if the mobo monitors the fans RPM which they do, then cutting the wire may just cause the Lappy to not boot up because its unable to detect the RPM in bios.

I would certainly leave it alone as the risk factor is way to high.

Wow, Lappy not boot? Even without the cable fan connected to the board the laptop boots and does not say anything, the fan just doesn't spin. Anyway my teacher said we could test this and if something goes wrong he can fixed it, he is really good with computers.

I will always keep in mind the warning you guys gave me, but i don't really use that laptop so often, my main PC is the one I am using right now and I would like to try something cool once in a while.

I also have a case fan that I don't use anymore, maybe i could test this theory before going for the laptop, anyways I won't do that by myself, to risky for me to do it alone.


Thanks to all, still if anyone got something to say I am all ears open.

Dont misunderstand what I am saying. A laptop and a destop are two different beasts and laptops have more thermal monitoring features. Some more so than others. If its old by all means have at it.

But you can not test the concept on a desktop because the bios of a laptop is designed diferently. And if it fails to boot it will be because of a detection issue as it scans the hardware. The bios of a PC monitors temps it can shut the PC down because of thermal issues. But PCs and laptops are so different when it comes to bios and thermal issues it isnt even funny.

If you do cut the "yellow" wire unless you can resolder it or buy a replacement fan you may cuase the laptop not to boot or become unstable.

A laptopcooler often helps the issue and or a replacement BIOS from the laptop OEM and or NEW fans fitted and a full clean of current fans and heatpipes in the laptop CPU GPU etc.

A word of warningeven opening a laptop case can invalidate the warrenty with many OEM's. If your outside the warrenty you can clean whats installed and this will help and look to find better replacements than were supplied.

So with some PC skills you can reapply: thermal pastes-pads clean the entire machine back to factory spec levels and change fans and heatsinks to much better models. this can have a dramtic effect on thermals and reduce them by 10-50%+ But WILL invalidate the Warrenty 99.9% of the time on a Laptop and carry a risk level of if your not sure what your doing you may damage the parts or get a fail to even boot.

Swapping a Laptop HDD to a SSD often reduces heat.
