If you go your route your into R+D mode.
Perhaps something like this might work.
I have literally zero experience in water cooling so I would like to ask if this project is doable.
My device is Asus n550jk with i7-4700hq and gtx850m. It's interior design looks like this. My plan is to remove the optical drive and place a small heatsink like this one. And by gluing a heatpipe like these ones to both the original heatpipes in the laptop and to my heatsink with adhesive thermal paste.
Then I will make 2 holes for the tubes on the optical drive side of the laptop (op. drive thickness is 9.5 mm by the way) and the rest will be regular water loop (which is an unknown to me at this point but it is the easy part I guess).
My purpose is to make the cpu throttling zero with temps below 80 degrees celcius. Currently I see 95 degrees and 20% throttling while gaming and the heat is highly annoying.
So, I plan to make an independent cooling loop but I have no idea if that will work properly or I will damage the device.
Any help is appreciated, Thanks.
