Aftermarket Internal Laptop Cooler Upgrade?

post #1 of 4
Thread Starter 
Ok, in a previous post, I was taking on the challange of upgrading the Celeron processor of a low end POS Acer Aspire 3680 to a Core 2 Duo. I was successful in doing so. I took the newly upgraded laptop into my robotics class the next day and started using it like I would normally use my other laptop, and by the end of the period It got pretty toasty, 60°C toasty. When I was upgrading the darn thing I knew it would be a lot faster, but did not even think about the heat increase. doh.gif The TDP increase was 25w (Celeron) to 35w (C2D) which is pretty significant if you consider that the heatsink in this thing is about as crap as you can get, it's a single bent heatpipe thats loosely connected to a low-RPM fan. I've tried everything in the book so far, i've completely removed the heatsink and fan and hand-cleaned each one, I redid the thermal paste (stock to Arctic Silver 5) and even straightened the heatsink fins, but its just still too hot. sadsmiley.gif So what i'm asking you guys, are there any Aftermarket *internal* laptop coolers available? And if not, what do you suggest that I do to combat this heat problem, Thanks guys!

So I take it that you were barely stressing your computer and the temp was still 60C?

Anyway, here are my suggestions:

Try to find a replacement fan that operates at higher RPM or better CFM. You can try to find another heat sink-fan assembly, but it will likely be a used part (of the same type you already have) stripped from a dead Aspire 3680.

You might also try finding a compatible P-series Core 2 Duo processor. They have 25W TDP vs the 35W of T-series C2D.

Finally you can try these last resort options:
undervolt your processor
use another thermal paste (AS5 requires time and power on/off cycling to properly cure)
clean out the intake and exhaust vents with compressed air
get a laptop cooler

Grab some IC Diamond thermal paste. It's just better. Seriously. I came from using AS5 and my temps dropped 10°C under full load in my older M17x R2 for both the CPU and GPU.

But as for a better aftermarket cooling system... none exist for laptops. If your machine doesn't have a vent below the fan, you can always drill a few holes to let it have a bit more airflow.

Hey everybody, thanks for the responses,

@elreyhorus, Yes, it sounds stupid, but after 15 minutes of having either Chrome or Word open, this thing gets scalding hot, and I'm not sure why, I thought that the T-Series had Speedstepping? And thats a good suggestion, I'll try to find another fan of the same size thats operates at a higher RPM with a higher CFM, I'll also take a look into undervolting my processor.

@Imglidinhere You're right, I looked into that IC Diamond paste, and everybody says that it works better than AS5. I'll probably end up redoing the thermal paste anyway, so ill just pick some of this up at my local microcenter next weekend.

Thanks for the tips everybody! thumbsupsmiley.png
