Aluminum?

Hi,

I would like to use liquid metal thermal paste for my CPU and GPU in my Pz770m-g. The problem is that I don't know if the contact area to the heatspreader is out of aluminum or not. Does anyone knows or can provide informations whom to ask or how to check myself?

Thanks in advance for your help,
Logan

 

Hi. It is made from copper, so you should be good to go. Many Clevo owners have been using liquid metal on their systems for a long time. This should be obvious when you take it apart, but it seems that perhaps you have not examined it internally.

 

First off thanks for the information and secondly nope I didn't took it so far apart that I can reach the PUs, because I am still using it daily mainly for work. Also I wanted to know before I opened it if I can use lm thermal paste or have to use regular silikon based. No all that's left is to wait for it to be delivered and then to apply it.

Btw I am playing with the idea of placing some thermal pads on some capacitors and such, even if it is just a minimal effect. What do you say?

 

Hi. It really depends on the circumstances. Some components get hot and some do not. If you put a thermal pad on a component and there is no heat sink it can actually make it get hotter because it limits airflow and has an insulating effect without a heat sink to remove the heat. In some circumstances, those parts will stay cooler with normal airflow versus being covered by a thermal pad.

 

Hmm guess I am gonna investigate what components would profit from a pad and if 0,5mm or 1mm.
Doesn't the plastic cover of the laptop kinda work as a heat sink, after all it has a copper alloy on the inner side?

 

Well, any solid material would be better than nothing. Plastic is not an ideal material, but it would offer some heat absorption properties. If it has a metal lining, that would certainly be better than a pad not making contact with anything. You could also use aluminum foil tape on the inside of the bottom cover and that would be better than the pad making contact with plastic.

 

A metal lining is the key to distributing heat through a pad.

 

Okay thanks for your help so far, once I have all the stuff and used them in my laptop I am gonna post pictures of the result in here.

If you have any other ideas, tipps etc. what I could do to improve the cooling let me know.

 

Adjust the thermal pads to make sure the contact his flush.

 

Heyho,

I've got the stuff today and aplied them after every preperation was done of course, like cleaning. Now the temps are roughly between 10°C and 20°C lower than before, less in idle, more in full load. In fact I never reach about 85°C in the later anymore, even when I OC and render or play games like KCD.

Thanks for the help guys and btw sorry for no pics, I forgot to take them. ^^

Cheers

That's great. So glad that was beneficial. Thanks for the update.

 

Nice work
