[CPU + GPU Temperatures + Benchmarks] - XPS 15 [9560] Kaby Lake

Well... Interesting development for my 9560. Over a year ago, back in March 2017 I put coollaboratory liquid ultra on the cpu and gpu... Just within the past week I've seen a major increase in temperatures. I'm now hitting 79C on an undervolted gpu... Very disappointed. Somewhat not shocked by this since my other previous experiments using clu ended up with a dried out clu. I'm guessing the clu is completely dried up and somehow moving the laptop caused it to break the seal... So now I'm kinda back to square 1.

I'm going to end up taking the clu out and using mx4 that I have some lying around. I have some extra thermal pads adding pressure to the cpu and gpu right at the heatsink so I'm hoping this helps additional cooling without the clu. Will report back later. I'm also in the process of moving...so timing couldn't be worse

 

I guess LM drying up isn't unexpected considering that gallium is known to migrate into copper. I understand the process slows down with subsequent LM applications and isn't as fatal as with aluminium heatsinks

I have some questions about PL1 power throttling on the 9560. I've repasted and undervolted the CPU and GPU and padded the VRMs, though I haven't done the whole iunlock mod. I'm still getting throttling after some gaming despite apparently decent temps.When playing a game, my temperatures seem stable and acceptable - GPU, CPU, VRM all at about 60C, but then the PL1 power limit starts dropping. Here's a HWiNFO screenshot: https://imgur.com/a/ejRr2YJ I closed the game when I saw the PL1 limit start dropping.

Why is my laptop throttling in this case? I thought the PL1 limit was driven by temperatures; am I mistaken? With these temps, am I safe just throwing in the hotel and disabling the Intel Dynamic Platform and Thermal Framework?

Any help would be appreciated.

 

Long term max power is 45W.

 

I recently find some posts or information about this Intel Dynamic Platform & Thermal Framework as being problematic with Throttling issues.

Can we consider it safe to disable them when an almost complete thermal mod has been made on the laptop ?
In order to completely avoid the throttling.

 

No

I'm pretty sure I'm using the same type/brand, but the bottom shell of the 9560 doesn't have a tight seal where those heat sinks are placed. If I look at the laptop from behind and with my eyes level to it, I can see that there's a gap. Did you have to sand/grind down the mini heatsinks for the bottom shell/cover to fit flush with the base of the laptop?

 

No, in fact I had to put a 1mm thermalpad just so they would barely touch the bottom case.

 

Hi all,
After some testing I'm observing some improvements after padding the PCH as well... Did someone tested that too?

Not that the max temperatures are lower, but throttling seems lighter and and fan isn't coming on too early.

Hope to hear from you!

Here is my build as of today:
