Modification request submitted for the SAMSUNG N145 PLUS.
Hi everyone.
I recently bought and restored a N145 netbook, and it’s performing well now that I upgraded it with an extra Gig of RAM and an SSD.
Although I was satisfied with its speed, I had some concerns about the temperatures.
I understand that rising temps are inevitable given the outside temperature of around 40°C and the internal heat, especially since it’s over 24°C even in the shadows.
Still, I want to keep this device as cool as possible and extend its lifespan.
According to the ATOM’s TCASE spec (if mannuals are correct), it reaches about 100°C.
Currently, my system is running between the 50s and 60°C, which is nearly halfway to the Atom’s threshold, but it’s already showing signs of throttling.
I’ve read that some laptops can be modified to lower temperatures, so before proceeding with the DREMEL upgrade, I thought it would be wise to seek your expert advice on this kind of significant changes.
Here’s the original (and theoretical) airflow diagram I have, and this is what I plan to adjust with the modifications:
And here’s the airflow I intend to implement again, based on the theoretical values.
My goal is to drill a hole over the CPU fan and install a fan grid to prevent dust from entering, allowing the heatsink to draw in as much fresh air as possible.
Would this approach be effective, or could it end up wasting time and resources?
Could the changes affect the airflow so that the intake vents become useless, worsening temperatures instead?
Might this impact the RAM and SSD performance or shorten their lifespan?
Looking forward to your thoughts.
I would not take that action.
It’s better to leave the Dremel aside...
Even though I see the need for cooling the laptop, my advice is to just add more RAM and check the temperatures as needed. This covers any other worries you might have.
The case was built with particular airflow in mind. Who can say what will happen if you go ahead with these changes? The engineers might be able to handle it and probably won’t approve.
Also, your modifications will nullify any remaining warranty.
Consider installing the RAM and monitoring the laptop temperatures. Try to keep things within specifications and proceed from there.
Avoid drilling holes or making changes without proper tools. The short-term gains are unlikely and could backfire. The drilling process itself is quite dangerous.
You’ll always retain the ability to remove the RAM if things get too hot.
Yes, it ranges from 36 to around 60ºC maximum while playing certain games as a test (Brutal DOOM, for example, with eyecandy ON).
