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... |

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. Phil Weldon "J.

well only thing you can do is clean the vents, the cost is like 7 dlls, and use extra fans outside and below the computerlike for 20 dlls, and use the artic silver thermal paste, this has to be put in the cpu and gpu, that will decrease like 15 to 20 degrees...overclocking its impossible in some laptops they do not allow controlling this or fan speeds J.
