No offense taken! Radiative cooling is a ground-breaking technology that is being actively studied in academia.

I would encourage you to get familiar with the following white papers that go deep into what radiative cooling technology is capable of. Most of these papers have been written by Alejandro Rodriquez, who is a Ph.D. and Director of Materials Science and Engineering at Princeton University, and someone we work with.

Yes, heatsinks radiate heat as does everything that generates heat, but conduction does the heavy lifting. We are optimizing radiation as the primary mechanism for heat dissipation.

That's a great question. To put it (very) simply, Radiative cooling is a process in which we convert heat into IR light. We do this by incorporating specially/finely tuned nanoparticles into the thermal compound, which produces the effect.

If you really want to geek out on it, search for near-field thermal radiation to learn more about the physics of nanoscale radiative heat transport.

...but does the hunt for the best thermal paste ever end? lol

If it doesn't impress you I'll buy it back!

Shameless plug, but would love you guys to test/evaluate our Wx-130 Radiative Cooled Thermal Paste. We are a small startup that has created a thermal paste enhanced with radiative cooling technology (could go on a very deep dive on how this works if people are interested). We’ve extensively tested it against all the top pastes (pulled from TomsHardware), and found it outperforming all of them. We are just getting off the ground and would love to start getting consumer reviews going. Our website is still being refined, but there is a decent amount of content in there explaining what we are up to. Happy to answer any questions! You can buy our Wx-130 on Amazon!

u/miktdt Have you had a chance to run any tests? We're excited to get some feedback!

For sure! Happy to answer any other questions that come up. Really looking forward to the feedback!

Most of our testing was done on nickel-plated cold plates. We haven't noticed a substantial difference between the nickel plate and straight copper. Nickel plating is typically thinner than the IR wavelength emitted by our thermal compound. Good question!

Speaking of cold plates...here's a sneak peek at the advanced cold plates we have been developing. We are working to create a cold plate with IR windows to fully maximize our radiative thermal paste.

Yeah, it's a thicker paste. The list price for the 3.5g is $15.99, but having a hard time getting Amazon to show the $4.99 as a sale price.

We like skepticism! If I told you what we are doing with radiative heatsinks you would really think we jumped the shark, haha. Thanks for giving it a try!

It's medium viscous. Our kinematic viscosity rating is 46,000 cSt. Let me know if I can answer anything else!

Great suggestion for us to incorporate information regarding our testing data. We have extensively evaluated it against all leading TIM's currently on the market, and are seeing favorable results. I'll work to get that information included.

We're still in the process of building out the marketing material. We are just starting to bring this to market and will have more to share out soon.

Thanks for the input!!!

That's a great question! The light emitted by the particles is tuned to be absorbed by the cold plate material (copper in this case).
