@John@OBSIDIAN-PC , Nice to see this lap and gap test options at your website. This will make it easy for any new buyer not to spend much time trying to fix the gaps and not to play a lot with thermal pads/past.

 

Well actually it used to give us more work.
Some time ago the gaps was something present in pretty much ALL P7 and P8 models, and it was BAD, really bad. We even had to solder extra copper to the coolers.
Latest units are not so bad so you should get away with just adding a copper shim.
Polishing all contact surfaces and specially delidding the CPU is something that helps.

Now waiting to start testing new generation CPUs.

 

How about some cooperation with @Stress Tech and be the firs seller provide the silver .925 lid.

 

I´m sorry but i been very busy, so i guess i missed out on that, can you link information about that product?

Thank you @Dr. AMK

And yes these lids are made from .999 sold silver with a 1mm extra height. But they are still in the process of being made. I have bought a block of .999 silver a few days ago. Hopefully they will be finished around next month or a few weeks. I had to change the design because of the coffee lake extra size die also the inner pocket height (talking fractions here) for the dies to make a better contact to the heat spreader which the BitsPower HS fails on this.
Please ignore the cheap .925 silver heat spreader with a cheap finish as the next .999 silver HS will have a better finish and a bigger, flatter surface area. Just follow the link that @Dr. AMK put up.

I will also like to add that I'm making something else for Clevo laptops. It's next level. Mark these words
It might be ready around January time though, because the way it is constructured

 

We bought some BitsPower too, was very unimpressed with it, makes little to no difference in the skylake cpus. We can get the same with stock IHS delided/LM and added copper to eliminate any gap.
Not sure what i´m gonna do with some dozens of them in my stock.

If you can do something better i would love to try it out.

 

BitsPower with "lapping" was very effective with my 7700k about 10c, I'm following @Mr. Fox school in that, but without lapping has no different.
Waiting to see what you will provide with the modifications you mentioned for the cooling system.
Wish you all the best.

Many are watching your work, something really out of the box, will help many of us to solve the heat problems of the Clevo's bad quality cooling component, until they redesign it to be more efficient. I think they should think about using any closed water cooling solution, even if they need to make it bigger, "about DTR I'm talking", I'm not an expert, but we will just wait and see.

 

What in the living hell? Even Command Rate is missing...not just tREFI.....

 

Like what @Dr. AMK said about @Mr. Fox method. Lapping the BitsPower lid does make a difference. I have tried and tested this.

Just out of curiosity; Do you add LM only on the CPU die, or do you add LM on the CPU die and on top of the IHS?

I have 2x products in the making. One is a .999 Solid silver lid with an extra 1mm height with a flat, polished finish. I will send you one to test and keep when it is complete! Just provide me an address please.

Then I have another product in a design stage. But it's a long way to go. If I fail on this design or succeed... I will still post my work on the Silver IHS thread.

What's taking so long is that .999 silver is hard to work with. It's hard to cast because it shrinks, it's hard to laser cut because silver is the most light reflective metal there is, and it's hard to chop because .999 silver is too soft. I have already lost a lot of money doing this, as I have tried multiple designs and process. This will be the last process I do. It's going to be done in Germany, with some Hi-Tec machinery.

My Dr told me to get a hobby. So now I got one .... Bit expensive though

Yes, I were thinking the same. Every heat sink should have copper pipes running through them, just in case Clevo users want to plug-in a water cooling system for when they are at home.

 

patiently awaiting prema's masterpiece haha ^^

Maybe try it with Kaby instead. And don't forget the lapping

 

Prema moded Bios are released?

 

nope, not yet

 

Thanks

 

Interesting that he found no difference.

 

If they purchased Kaby IHS instead of Skylake it would not provide any cooling benefit because the IHS is short and does nothing to improve contact pressure. Not sure which ones they ordered.

 

Also is it stock vs lid or stock lid + copper vs bitspower lid.

 

I am not sure what that means. It's either one or the other. The Bitspower IHS replaces the stock IHS.

 

Yes but he was saying they use a stock lid with a copper shim of some kind normally.

 

Oh, OK. Now I get what you are saying. Sorry it did not make sense before.

Yes, they do a mod where they solder a copper shim to the heat sink like I did. I copied their example and it worked really well. Much better than a shim with TIM on both sides.

I think they were hoping the Bitspower IHS would eliminate the need for that. Using a Sky Lake IHS most likely would eliminate the need for it. If they purchased the short (stock height) Kaby Lake Bitspower IHS it would do basically nothing to improve contact pressure and would be a waste of time and money. It would still need to be lapped for the best results. The concave IHS top is an issue for laptops with flat heat sinks, or warped in the opposite direction. Creates quite the air pocket with no contact where it needs it most.

 

Are you able to locate my orginal post with comments for user with removed c-clips?
I can't...

 

Weeird. Cant find it either. I do have the image saved -

Or lay the card flat on the heatsink and judge yourself if you don't like any of the guides

 

Is, or has there been any announcements? What is the next major update to the P870KM1-G systems?

 

The P870TM/NP9877 has been announced, this brings in the z370 chipset and hex core support.

 

Is that it?

The 17 (UHD) monitor - is it 60/120Mhz?

 

I purchased this machine with the delid Liquid Ultra and seeing as this is my first experience with it I wanted to know how often I need to clean and reapply a fresh application.

 

who did you buy it from?

 

Only do it if you notice your delta T from ambient increase a lot.

 

I've been considering ordering the P870TM from HIDevolution and I'm wondering if the vapor chamber upgrade is worth the cost if it's just going to be equipped with a 8700k and a GTX 1070.

 

It depends if you intend to overclock really. It would keep things running as cool and quiet as possible otherwise. If you have the spare budget then I would.

 

It's either that or get a 1080 but I don't know if the 1080 would be worth the extra $400.

 

It's worth it from a performance stand point yes, it's a large jump up.

 

Hows the heat management without the vapor chamber? Or is it kind of a requirement?

 

A single 1080 gets an upgraded cooler over the 1070 as it is so is reasonable. A vapor chamber again is nice on top of that still.

 

Interesting. Thanks for the information

 

Okay, thanks!

I bought it from HIDEvolution.

 

Not a problem, there are a fair few options on this chassis

 

On a somewhat unrelated note, do you know if the keyboard from the P670rs can be swapped into the P870dm3?

 

No, I don't believe so.

 

RIP my chicklet hopes and dreams.

 

Some people love them, some hate them.

 

from hidevo I think repaste is not necessary

 

As I said, only if the delta T from ambient rises by a large amount and to add to that if cleaning the fins with compressed air does not restore the original temperatures.

 

Hey guys. Sorry for the duplicate post. But since this is the official P870KMx owners forum. I just have a question for any P870KMx owner here who sees this post:

Have you used an external mic via the mic-in port ? (not USB) Does it work for you ?

 

Whoops, was getting my end letters confused.

 

I have a stereo headset that uses the headphone and mic ports. It works, I used it with @Phoenix when he was super tweaking my computer.
