Hello today i water cooled my helios 16 with i9 13900hx and rtx4080
So i saw around 12c to 15c difference at the cpu at 55 and 100 watts with low to medium fan speed i didnt test the gpu yet i did it mostly for cpu
The copper tube is touching the heatsink with thermal putty and thats it this is why i called it amateur way bc i didnt want to solder it
Can you share more pictures

Unfortunately, I didn’t take pictures from the bottom because it was hard to align and take pictures by myself. Maybe I’ll update later, but from the bottom cover, everything is covered apart from the outlet pipes.
@Sam
Got it, you mean the bottom. Thanks for clarifying!
I’ve seen this technique on YouTube and was curious about trying it myself. Just didn’t want to drill a hole into my Asus ROG Zephyrus Duo 16, nor do I think I can spare the space, though its airflow is already quite good. I just wanted more.
@Asa
I got the idea from YouTube as well. I experimented and it worked, but you may have problems with the space; even mine is almost hard to close the cover.
How about setting higher PL1/PL2 CPU limits for Cinebench runs to see how your cooling system manages with sustained performance?

I tried it because you made me curious. A 10-minute R23 run scored around 30500 and temperatures were high 80s to low 90s with the pump running at half speed.
@Sam
What was the previous score?

I don’t remember exactly but I think it was around 27000 to 28000.

I’ll try again tomorrow.
Great job on this cool project!
@Bennie
Thank you, I really enjoyed working on this!
This setup seems obsessed with cooling. Did you manage to undervolt its CPU? Could you share a screenshot of the ThrottleStop limits? I assume you have the coolest Helios 18 in the world, just curious about why my Helios 16’s limits were triggering—was it due to temperature or something else?
@Zhen
This is a Helios 16, and unfortunately, I can’t undervolt the laptop. In ThrottleStop, everything I can unlock is unlocked, and your limits are probably due to temperature or power limits.

The inability to undervolt was a dealbreaker for me when considering the Helios.
Linus Tech Tips did a similar modification on an ASUS ROG laptop.

Yes, I watched that video a couple of times. I followed the same method they did, except for soldering.

If you prefer not to solder, you might find better results with a RAM water block or a direct die CPU block like I used on mine. It’s challenging to maintain good mounting pressure with the pipes, and it doesn’t work as well otherwise.
I would really like to know the Cinebench R23 scores for multi-core and single-core over a 10-minute run. Thank you.
