Indigo Xtreme is a really unique TIM: it has no cure whatsoever, it makes near-perfect contact almost every time, and it’s a totally different form factor. What does this mean for testing? Well, it’s the best option for doing multiple tests in one mount (like what we do for flowrate vs. temperature and all the iterations of that). Because it also gets near-perfect contact every time, it allows us to nearly isolate a block’s internals from how good of contact it makes. And with that, we can also use it to judge the quality of contact of blocks, based on how much worse they perform relative to Indigo Xtreme. Long story short, Indigo Xtreme allows us to observe performance at different flowrates, quantify the quality of contact, and directly compare blocks’ internals.
For all of the following charts, performance is based on the best mount of the block with any TIM…it just happens to reliably be Indigo Xtreme.
With Indigo Xtreme, the Apogee XT rev2 lands just behind the CPU-370. With only 1.5c improvement from MX-2 to Indigo Xtreme, we have an early indication the Apogee XT rev2 makes really good contact.
It’s important to note that all flowrate/pump setting/hydraulic power spectrum tests are done with Indigo Xtreme (has zero performance change over time, unlike any thermal paste) and then justified to the blocks’ best mount.
