If you remove the heatsink you should check the paste on the gpu die it can be seen if it is evenly distributed or not. You should see also if it is not aligned, leaning on a side or missing from corners or sides.

 

Finally I smeared it with paste and that solved the problem... in the end, paste is the best... always!

 

Default:

 

"Tested"

 

During the Time Spy test, the GPU temperature reached a maximum of 79 degrees and the HotSpot temperature was 87 degrees.

Just curious, did you use kryosheet on gpu die and that caused the problem?

Also for other parts then the gpu die the Thermal Grizzly Putty Pro seems to be very good so far.

Especially for not original parts when you do not know the exact pad sizes.

Of course, it's been a good and interesting method so far...I've used Kryosheet chips a lot, cut to size exactly as needed.
According to my friend, it also degraded...that might have been the problem...(?)

I used it for both CPU and GPU.

Thanks for the heads up. I have no experience with krysheets so far. 
In theory it is not better than paste but it has low maintanance.

It is already degraded then its a good experiment not to use them.🙂

I prefer to use paste, it's safe and definitely good! 😁✌️

Hi,

I don't want to upset you, but the factory cap is also (nickel-plated) copper... 😉

The water cooler is a big hit, that's for sure!

What they add to t.pad is also perfect!

 

So ive got the heatsink and delided my 11900k and it arrived today along with my 780w Eurocom PSU. Happy about the PSU but the heatsink is giving me headaches. Not only did it arrive bent but it also seems to make bad contact and no matter which pads or sizes I use its worse then stock. I used Nanogrease extreme and the pads that came with it. Also tried it with arctic tp3 but that didnt improve it. Im seeing mid 80s on the GPU compared to mid 60-70s on the stock heatsink. 

Which pad sizes did you use? The seller recomendation seems to be not working. Is there anything youve dont to make it work? My air cooled performance is 10C worse then before...

11900k in an smg?

How do you like the 780w psu? wanted to buy one myself tbh, bringing around the 2 bricks and adapter is annoying

No, thats in my KM, but i used the wrong thread without noticing for my first post, so i guess ill just continue here ^^ 

 

The 780W Eurocom is really cool with its real time wattage display but i think this is only necissary for when you watercool and heavily overclock. Because the combined 560w of the two psus are totally fine otherwise. If you only want to buy it for portability, might be worth it if you get a good price; found it for around 80€ on eBay brand new but the shipping costs to Germany brought it to almost 200

Also planning to get the gt600 air cooler, i heared it'll really help

mh, you may find it is helpful and more portable, the standard heatsink, putty, ptm 7950, delidding the cpu and use the rockitcool IHS with some LM, polish / level the heatsinks and get the fans from taobao, those with more finns and as I happily found out, quieter on the ears.

 

Thank you for the PSU's report, so no problems? noise? cables etc

Yeah, it seems like it. I had hoped to gain better air cooling from the heatsink aswell, thats why I bought it. I did delid my 11900k with LM but the rockitcool IHS isnt available anymore and neither is ANY copper IHS not even Bartex. There are 9900k 10900k and 12900k and above IHS but no 11th gen... 

As for the fans are they really that different from the stock ones that its worth buying? I only really care if they perform better, quietness is secondary for me. 

The PSU is great but yeah you do hear some noise but barely audible especially when you game or have headphones on. I dont know what you mean with the cables but you do need to note that you need buy a different wallplug cable if youre outside the US

I haven't been on in a while, I am still happy with my X-170-sm-g, but it is time for a refresh. I am not an engineer so I had to ask for some help pulling this off.
 

I basically said that I want to gut the x170-sm-g's internals and design a new motherboard with the spec I want so I can basically do a motherboard swap and this is what I was given back:

Great — Version 1 (Realistic Clevo tone) is locked in.

According to the engineering diagrams that it also generated for me, this laptop can be built into the current X170- sm-g case. It will have proper air flow for cooling.

Now where can I hire a fabricator to actually build, test and stress test the motherboard so I can upgrade my x170 sm-g

I see this as a completely unnecessary step... You'd better buy a factory i9-275HX + RTX 5090 (24GB) machine that is sold by TongFang. I did the same! Since then, the X170SM/KM-G has been put in its box...

I get what you are saying, I haven't seen the machines by TonyFang, but I bought into the x170 series because I wanted desktop performance in a laptop. the  i9-275HX no matter how it is sliced and diced is a mobile processor and under load just can't compete with the desktop Core Ultra 9. 

An intel based machine with an  i9-275HX is an Apple move..... to keep the temps down, it has to be throttled, if it is throttled you aren't getting peak performance when it is needed. 

I also want the extra pci lanes and M.2 nveme slots. here is no reason with what is possible right now to be stuck with 3 nvme slots and 256gb ram.

Cooling tech has also improved.

I am still going to look into getting this board made, If I am stuck with the mobile processor then I might as well get an Alienware door stop.
