Laptop Super Heatsink...

Hello,

I am looking to overclock my laptop which has a Pentium-M "Dothan" core
as the CPU. I spoke with another individual who performed the overclocking
mod on exactly the same model of laptop that I have. He talked about the
CPU overheating a lot because the heatsink was insufficient in handling the
extra heat.

So, what I would like to find out is:
What can I do to improve the performance of my current laptop heatsink?
-=OR=-
Is there a place where I could purchase an improved heatsink for my
laptop?

TIA...

Very little and no.

In general there is no more room in a laptop for a larger heatsink... if
there were, the stock heatsink would be larger. The heatsink/fan in a
laptop is highly customized - perhaps a copper plate attached to a heatpipe
that then is attached to a finned heatsink with a fan.

You can decrease the CPU temperature easily by operating the laptop in a
colder-than-normal room environment, keeping clear airspace around the
laptop, and using additional fans to improve air flow. While the above
MIGHT be of some benefit, the best you might expect is that the CPU would
run at its top stock speed with less clock speed throttling from
overheating. But since the laptop will have no way of increasing the
FrontSide Bus speed, locking the PCI bus/AGP bus speeds to 33 MHz/66 MHz,
changing the memory / CPU ratio, or raising the CPU core voltage you still
are unlikely to be able to overclock, certainly not to an recognizable
extent. And with the obsolescent Pentium M 'Dothan' CPU, you likely have a
low performance graphics adapter that, in first-person-shooter gaming for
example, will be the major bottleneck.

While it MIGHT be of some benefit to check and replace the thermal compound
between the heatsink plate and the CPU, the best you might expect is that
the CPU would run at its top stock speed with less clock speed throttling
from overheating. The downside is that actually getting TO the heatsink,
removing it, cleaning it, replacing the thermal compound, and finally
reassembling the laptop is going to be VERY difficult, with a good chance of
not getting everything right, and eventually mechanically damaging a circuit
board or connecting ribbon. Laptops are NOT designed to be taken apart or
overclocked.

Bottom line - Don't do it. It isn't worth it. You won't improve
performance. You may end up without a working laptop.
