der8auer Posted February 25, 2016 Share Posted February 25, 2016 If you benched Skylake on LN2 already, I'm sure you had some kind of cracking issues. We already tried a lot to improve the cracking. Mainly by changing the thermal paste. However, also the black glue between IHS and CPU PCB seems to help. At least it was much worse for me whenever I removed the black glue. It's just a guess but I think the space between IHS and PCB has some kind of influence on the cracking behavior. I made some spacers out of stainless steel. The thickness is 0.10 mm and you can stack them e.g. if you want to use 0.30 mm spacer. Just fix them with a little bit of TIM. This is a pure research project - nothing I'm trying to make money on. I have 50 spacers here and paid 3,75 € per spacer. Would be cool if some guys join in and help me investigate further. I can ship a pack of 5 spacer worldwide for 23 €.

Gunslinger Posted February 25, 2016 Share Posted February 25, 2016 Count me in, you can ship me a pack and I can mail to anyone in the US wanting to try it. Quote Link to comment Share on other sites More sharing options...

xxbassplayerxx Posted February 25, 2016 Share Posted February 25, 2016 I have never had a single crack on either of my Skylake chips and both have the black glue on them still... so I totally agree with you here. I imagine the thermal paste is trying to expand as the chip rapidly starts putting out heat. If there isn't room for it, the pressure builds until you get the crack at which point the pressure from the paste trying to expand is greater than the pressure holding down the pot. The crack is literally the sound of the paste exploding. Scratching the die makes sense here as it gives the paste a bit more room to expand. I'd take you up on a pack but I don't want to remove the black glue on mine lol Quote Link to comment Share on other sites More sharing options...
Crew Leeghoofd Posted February 25, 2016 Crew Share Posted February 25, 2016 (edited) I'm in, but doubt if we even need more than 3 or so. So if we can determine the good spacing height... we get a fully copper IHS from Der8auer with the right dimensions Edited February 25, 2016 by Leeghoofd Quote Link to comment Share on other sites More sharing options...

DrWeez Posted February 25, 2016 Share Posted February 25, 2016 ooooo cool idea.... if only the shipping to SA was not 45 euro. i would so be interested in testing as well Quote Link to comment Share on other sites More sharing options...
der8auer Posted February 25, 2016 Author Share Posted February 25, 2016 ooooo cool idea.... if only the shipping to SA was not 45 euro. i would so be interested in testing as well no no. I will ship then in a small letter. 23€ already includes the price for 5 spacers + shipping. Quote Link to comment Share on other sites More sharing options...

der8auer Posted February 26, 2016 Author Share Posted February 26, 2016 I will keep 10 myself for my own testing so I can send out 8 packs of 5 spacers.

joe_cool Posted February 26, 2016 Share Posted February 26, 2016 Hey Roman, i will test this little thing next week @ cascade. And i have also some more advanced ideas for milling... I will let you know if i can get some improvement with this. Because i will not start a mass production of anything like that, i do it only for myself.

der8auer Posted February 26, 2016 Author Share Posted February 26, 2016 Hey! I had a similar idea but I'm not sure about the correct dimensions. That's why I made the small spacers so we can test to find the correct spacing Quote Link to comment Share on other sites More sharing options...

That's why I made the small spacers so we can test to find the correct spacing I will start with the normal 0.35mm deep milling in ihs and can go deeper anytime... Without glue on cpu i think you don't need more than 0.5mm. In my opinion, we have to focus more on the backplate then, to get the optimal pressure. _ Quote Link to comment Share on other sites More sharing options...
