Good advise to ppl that bought the CoreBook

[The Hacker]

Today i took my Corebook apart to look inside, also removed the heatsink, and god damn a mees Chuwi did with the therman paste, so my advise is to open, remove the heatsink, clean up the mess and then add new thermal paste

Useful to check. Thanks.

I have followed your support on the Corebook Indiegogo page.

I wish we could see the real production line for Chuwi products. They must contract-out the production to a cheap generic line to save money. How else can the thermal paste, and other silly problems, happen?

I supported last years Surbook campaign & got a good unit. However, I recall someone had to take the back off a Surbook to attach the keyboard ribbon to the main board!

These problems can only mean that no quality, or 2nd check on the line, is ever done. The units are put together, switched on & off, and packed into boxes.

How were the thermals? Was it that bad you needed to open it?

The back cover, and even the fron was getting around 40-45 °C when charging it, so wanted to see if i could do something about that, that’s why i removed the heatsink

Damn that is a lot of thermal paste, good thing there doesnt seems to have enough pressure pushing down on it or it would have possibly covered half the motherboard.

for a thermal mod i guess just a thermal pad between the copper heatsink and the back cover to push down on it would be more than enough

After replacing the shitload of white thermal paste and applying some Artic MX-2 i have lowered the temp while charging arround 10 °C, so it now only reach arround 33-36 °C

Hello, how did you open you corebook?

[Hualalai]

Chuwi logic: a ton of cheap thermal paste is the same as a little expensive thermal paste. ????

[Manni]

Can you show us how you opened it? Please, I am desperate to change SSD and paste.

[Brad]

The more I learn about these brands, Chuwi, Jumper, etc., makes me just want to stick with the bigger cheap brands like Lenovo, Acer, etc.  For perhaps better quality and also availability of parts if something breaks.

Omg, I just redid the thermal paste. It was really bad. It looks like changing the SSD will be no problem. But now the Intel WiFi card is not detected. There is an Unknown USB Device error. This is very annoying.

Hi! Can you show us how you managed to remove the back panel? I’ve been trying to take it out but can’t manage to get my tools through the gaps. Also, what type of SSD is used?

Thanks!

too much paste does not matter
what matters is when you put the heat sink on the chip again you apply pressure over the contact area and do some circular motions to press the not needed material out of the contact area. The circular motion also fills the micro gaps between the contact area.

There after it is always a good idea to put permanent pressure via a thermal pad or a copper shimmy on the contact area.
