Here's a possible fun test case for your new high precision CPU heater that I've been curious about for a few years:
Tinting ... I remember a few years back I actually read the instructions that came with a tube of Arctic Silver (for some reason).
It suggested Tinting the IHS and cold plate by applying a tiny amount of paste to them then buffing it back off.
At first I thought it was just a clever way to get people to use more paste, but as I thought about it, it started to make sense.
By buffing in a microscopic layer of paste, you can apply more direct pressure to the surfaces, filling in the tiny imperfections with more force than just the mounting pressure of the cooler, so when you apply the paste to like usual, and mount the cooler, you'd theoretically get better contact.
There would be no way to detect any improvement by using a real CPU, but your test rig may actually have the resolution to check this.
Just a thought.

I'd be interested in knowing if gold leaf (you can get thicker varieties), being relatively soft yet solid.
Also, I'm curious to see the hotspots of different CPUs (Ryzens being wonky) and hot much the IHS actually spreads the heat. Take Ryzen again, CPUs with only CCS have the bulk of the heat on one corner. That must have an impact on heatpipes? Maybe embed a series temperature probs in the surface of a heatsink or waterblock that you can rotate 90 degrees to map wear the heat is located. I think a thermal camera would be a great idea if you can find a way to read the source not the reflection.
Can't wait for a comparison/ review of all the TIMs on the market.
(Or just the popular ones.)

first considering the nature of pads i'm actually impressed,i thought they would of been much worse than they actually are,2nd when you buy a new cooler every few years i don't buy a new cooler that often,shit i still have the original cm hyper 212 here that i gave to my younger brother,i myself have a noctua D9L (i have a case that has a cooler limit of 130mm) and i highly doubt i'll be swapping it any time soon.
pads would be good if you don't trust/expect the person to be able to re apply the paste over time themselves (like your mum or grandparents etc)anyways appreciate the in depth review.

Recently moved to Kryonaut from using an IC pad for the last two years. My 8700k is OC'd to 5.2 GHz at 1.36v. While using the pad temps would hit the mid 80s. After switching to Kryonaut I ran CBr20 for two straight hours. Temps shot up to 79c initially and settled down at 74c after my Celcius S24 was saturated. Currently have a PC-o11 Dynamic with the s24 mounted for exhaust at the top with three 120mm fans for intake on the side. All fans are FD X2 dynamic PWM fans all running at a static 1000 RPMs.

Aluminium oxidizes naturally, it's just that we're used to seeing the oxidized version of it. Unlike steel, it self seals and the oxidation layer prevents further oxidation beneath it, so it's corrosive effects make it more akin to a layer of paint than something that will further degrade the material. Maybe a useless piece of info, and the factory might chemically speed the oxidation process up, but thought I'd mention it.

It seems pretty much impossible to actually test decently but how do you think it would perform after say.. a couple years, compared to a couple years old paste
Would the paste still have better performance?
Because i'm not quite sure broke enthusiasts are changing pc/cooler every 3 years or so (Though nothing stops people from changing paste, but you see my point)

Gamers Nexus, after watching your review on the thermal pastes and pads, if one was wanting to redo the paste/pad of a slightly older laptop that seems to run a tad hot which would you recommend then? It has been a while since I've last looked into this and I really enjoy watching your videos and what you guys do for the computer world with your reviews. Thanks.

can you do real mounting pressure tests? it is really hard to tell if your tests bottomed out on the mounting peg, and what the actual interface pressure was. looking at research, mounting pressure is really important, and it might be better if mounts returned to a spring-type system to more easily account for manufacturing variance.

Any chance that we could see a longevity test for the pads? I have found that the tropical climate where I live dries out every thermal paste I have tried so I was hoping that the pads might be a better long term solution. I hate having to clean out all the thermal paste dust every time I remount my heatsink.

I have a carbonaut on my CPU right now and when I took off my cooler for cleaning, the pad just felt like thermal paste and when i tried taking it off it just broke into pieces pretty much. Sounds great in theory but I highly doubt i'll be able to re-use it for my next CPU (i've had it on my CPU for 5 months)
