Case modification for SAMSUNG N145 PLUS

[arajigar]

Hi everyone.

I have recently purchased and restored a N145 netbook, which is working like a charm now that I added 1 more Gig of RAM and an SSD to the system.

Although I was quite content with its performance, I was a bit worried about temps. Iknow that I must be realistic about temps rising, overall with a temperature of 40 degrees celsius outside of my house, and more than 24 inside even in the shadows, but... I want to maintain this little jewel as cool as possible and make it last as long as possible too.

Atom´s TCASE (if mannuals are right) is about 100º degrees Celsius, and my system is running now between the 50s and 60 degrees, almost half the way to the Atom starts throttling, but I have read about laptops can be modded making holes in it to achieve lower temps. That´s why, before taking the DREMEL, I wanted to ask you for your expert advice about this kind of radical procedures.

Here´s the original ( and teorical) airflow of this netbook (I know the diagram is kinda ghetto, sorry):

And here´s the modification I want to make WITH (again) the theorical airflow.

What I want is to make a hole over the CPU fan and put a fan grid to keep dust from entering the case, so the CPU heatsink can take as much fresh air from outside as possible.

Will it be a good idea or it´ll be a total waste of time and resources?
Will the airflow be changed so the under intakes will be useless and so making temps be worse?
Could this affect RAM and SSD reducing their lifespan and performance?

Thanks in anticipation.

I would not do that.

Put the Dremel away....

Although I understand the concern about keeping the laptop cool, my suggestion is to simply install the additional RAM and monitor temperatures accordingly. Along with anything else you are concerned about.

The case was designed with specific airflows in mind. Who knows what will happen if your ideas are implemented. The engineers may be able to do so and very likely will say "no".

Plus, your mods will forfeit any remaining warranty.

Add the RAM and monitor laptop temperatures. See what you can do to keep things cool (within specs) and go from there.

Without drilling holes or otherwise "modding" it. The benefits, if any, are likely to be short term and end badly. Just the drilling process itself is very risky.

You will always have the option to remove the RAM if the laptop gets too hot.

Just my thoughts on the matter.

Its currently at 60C max?
Leave it alone!

Yes, it goes from 36 or so to 60ºC max playing some games as a test (Brutal DOOM, for example, with eyecandy ON).

And 60C is zero problem.

Leave it.
