CPU aftermarket cooler?

Does anyone know if it exist stuff like so for notebooks?

 

The only ones I've read/heard about are frankenmonster stuff that have been haphazardly put together and even then, they are not portable anymore. (Bottom plate(s) off permanently, hoses routed to external (big!) fans, powered by old (desktop) power supplies... etc.).

The best you could do is to get the existing cooling system in tip top order. Clean the inside of the notebook for dust/debris thoroughly, including the vents (intake/exhaust), fans, fan blades etc.

Also, repasting the cpu/gpu and using new cooling pads (or even better, copper shims where appropriate) with a high quality paste like ICD should give you as much of an improvement as you can hope for.

Good luck.

 

Depending on your system you can sometimes get aftermarket fans which have a higher flow rate/are less noisey than the stock ones.

 

Could you elaborate a bit on copper shims or point me somewhere for some basic info on this? All I've been aware of is paste for contact.

 

If you're up for a laptop cooler, perhaps, here's a thread to start with:

As NBR uses the term, a shim is a piece of metal that goes between the heatsink and the CPU/GPU die to fill in the gap between a poorly fitting heatsink. Air is a terrible interface for transfer heat efficiently. Previously, that gap would have been filled by a thermal pad which, although it closes the gap, has less efficiency than a metal-to-metal contact. Each face of metal in contact would need to be pasted with thermal interface material ("TIM") such as arctic silver or icd7 to ensure the best heat transfer. Some people will try to fill the gap with icd7, but that's a dangerous route to go because the paste can shift or displace over time, and because there's no direct pressure between the metals. (Metal to metal contact is better, metal to metal under pressure via a spring is best for minimizing air gaps.)

The more you know:
CPU shim - Wikipedia, the free encyclopedia
This is the classic definition of shim, back when the die itself was exposed. They were used to prevent uneven pressure from cracking the corner of a die. Now, heatspreaders also distribute the stress so there's less chance of cracking anything.

 

Thanks for the update. I didn't know that shims had ever been used w/cpu cooling.

Do you think shims(plus paste) would be much better than just good paste in a modern laptop, such as a Lenovo W520?

Most of what I've seen in discussions has centered around cleaning the laptop, quality of paste and how well the cpu chip is seated. If shims were that worthwhile these days, I'd guess there'd be more discussion about them.

 

A good quality paste and a good pate job is all you'll need, i wouldn't try lapping the heatsink either.

 

Shims are only necessary where you have an uneven height between different pads (e.g., 1mm thick pad on the CPU, 2mm thick on the GPU). In most cases, the pads are the same thickness so it isn't necessary to shim - the pressure from the spring screws is usually still sufficient over the longer distance to keep the heatsink secured well enough.

Using a shim when you don't need one is dangerous - too much force leads to a cracked chip or motherboard. Shims don't compress like thermal pads do, so it's very easy to put a piece of rigid incompressible piece of copper that is dangerous even though it is only 0.1 or more mm too thick or even the same thickness, so it's safer to avoid them if possible.

 

Got it; thanks for the info...

 

Can you post some links pleas or some brands to search for I want to change my VAIO Z series CPU cooler do to the fact that it runs at 70°C + when I play some games
