Tschooo-tschooo! All aboard the watercooling hype train!!!

Re-using an water-cooling-setup from my old G5-Mac. Total overkill for cooling those drivers 
Interesting!..I have the last in the series of the liquid cooled quad core G5 which was made, I think in 2005!!!
Is there anything you would change about the DICE design?
I thought the drivers were supposed to dissipate heat into the Al frame quite well?
It turned out that I still need a small 5V fan to get at least the tinyiest amount of airflow. Totally passive this way is working only for shorter prints. 5+ hours and there are lost steps… And it is depending heavily on environmental temperature. If I could, I would redo the printhead with its partcooling. But there is no other way with the space given.
Fair enough. What about a heatsink with vertical fins on the back - you’d get some natural convection?
One needs the cooling right where the drivers are located…
…flatten a piece of copper pipe to run the liquid through right where the drivers are at!
Space needed for that! There is no space in the DICE left for playing around 
There is no space on the DICE, period. I’m pretty sure the print goes above the lid 
Well I guess I’m about to find out. Is the 3510 part cooling fan not powerful enough? I have experience with the slim 3507 and I needed two of them and need to be directly pointing to the tip of the nozzle. They are not really that powerful compare to the regular blower fan.
@Step_Cia I’ve started laying out plans for a 200x200 build size COREXY based on DICE and also using some other machines like ECLIPS3D for inspiration. Per advice from @Rene_Jurack I think the head will be scaled up some (to be less microscopic) and use more common items like a 4020 blower fan for part cooling. Let me know if you want to collaborate some or loop in to our design process.
I don’t understand how the water cooling rig is helping cool the drivers.
That sounds interesting @raykholo what collaboration tool are you using? My skill set is kind of limited to fusion 360
@Jeff_DeMaagd the drivers are attached to the frame, and the cooling head is attached to the opposite side of the frame
@Step_Cia hangouts chat and screenshots
We’re throwing around ideas. I work in Inventor.
Oh I see what’s going on. If water cooling is going to be the solution, further changes can probably use unmodified drivers and run a custom long heat sink.
Yeah, these trinamics run hot! Although I’m doing fine with an 80mm fan and some heatsinks. Rene does like his overkill though…
And I meant a custom long water block at that. I’ve water cooled my hot end upper block but didn’t consider the motor drivers.
Jeff I was saying that I can cool these drivers sufficiently with an 80mm fan blowing on some GDT-X9 heatsinks. I understood you were referring to a water cooling block. There’s no space on dice for an 80mm fan!
