simple methods to increase [laptop] thermal performance[?]
hello
can you tell me please what should I do to grease the fan of my laptop? would that increase thermal performance? any other advice along with placing thermal compound like Arctic Cooling?
also, any review that thermal tapes can do better than thermal paste?
thanks

My general advice, not knowing the recipient, would be to not do anything.
Taking a laptop apart without access to the proper service manual is something that even I, a professional service engineer, wouldn't do unless it's absolutely necessary.
If, however, it is taken apart, then the first "fix" to improve cooling would be to simply blow the heatsinks and fan free from dust and then test to see how much it helped.
- Never apply grease to any fan! (Unless specified by the fan manufacturer.)
- Thermal "grease" (aka TIM) is to be applied between the hot item and the heatsink.
- "Thermal tape" is generally worse in performance than proper TIM.
Hope this helps.

Laptop heatsinks are tailored to fit each specific model. Any replacement must be to an identical one, and is therefore irrelevant.
All really efficient ways of improving the cooling laptops are external.
- Make sure there's plenty of free space around all openings.
- Run the laptop with the screen in "open" position, since the keyboard too acts like a heatsink.

This is true for Desktop computers.color wrote:but it is well known that heatsinks that come with processors do not compare with those that you can add afterwards
However, due to the limited room and not standardized arrangement of components inside a laptop case, it is very very improbable that you will find anything that fits. Even if you find something that you can mount and if you can close the case afterwards it might block the airpath or have other unintended side effects.
So, in short: Don't do that.
