    *PLEASE,* IF YOU'RE STILL EXPERIMENTING W/ OUTSIDE-THE-BOX PC COOLERS: try adding a coiled copper tube that passes through a modified mini-fridge and splice it into the circulatory system of the submerged mineral oil PC (because you'd no longer need to worry about water condensation frying shit)!

    also, a note to Jake: i _think_ that pipe bender is capable of bending up to 5 tubes at a time (FYI).

    You should have used a large thin bolt with rings between the plates to make it more sturdy more efficient and better looking... but most importantly i don’t see any RGB!!

    Thinking about it, if you cut those fins in half and added more of them onto the pipes, it’d increase the effective cooling of the heat pipes...

    Alex make a mk 2 please this engineering/hackery style videos are the best

    The machinist I me is screaming at you guys.
    First off, learn how to drill a damn hole.
    Second, use a for h on the heat pipes that will help you bend them further.

    Thermal Cameras don't actually work on Metal surfaces. You have to coat the surface with matte color to make it read out the temperature correctly. No wonder why the heatsink baseplate looked so cool in that image. I assume the capacitor hat some coating on it which made it visible to the Flir.

    using W/(m.K) MG Chemical's thermal adhesives at 75°F has a value of between 0.8-1.4, depending on which formulation. at 68°F tin(solder) is 62.1. the base block being made of aluminum, it has a value of 225 vs 401 for copper, only beat by silver with a value of 419. a silver-bearing low melt tin-based solder would not burst the pipes and would dramatically improve...everything. replacing the aluminum block with a copper one would also help, nearly doubling efficiency. www.mgchemicals.com/downloads/comparison-tables/Thermally%20Conductive%20Adhesives%20Comparison%20Chart.pdf / neutrium.net/heat_transfer/thermal-conductivity-of-metals-and-alloys/

    If you'd mounted every other copper pipe on alternate sides and split your alu plates into thinner longer rectangles, then used washers to space it out, it might have looked better

    Cut down the plates closer to the heat pipes and use fan to push air through the heat sink instead of pulling it out since you are using only one fan. Else use 2 fans.
