Thermal GrizzlyConductonaut - 5 Gram - High Performance Liquid Metal Compound Thermal Paste for Superior CPU/GPU/Console Cooling - Made in Germany

TL;DR:AMD Threadripper 2950x paired with Corsair H115i Platinum RGB water cooler, 'balanced' fan mode speed (~1100 rpm) on radiator. Corsair OEM, pre-applied thermal paste - idle 104F, load 157F. Conductonaut applied - idle 98F, load 149F; both tests 10-15 minutes of Prime95.MAIN REVIEW:I have the AMD Threadripper 2950x 16c/32t paired with the Corsair H115i Platinum RGB cooler. The 2 Corsair fans on the radiator are spinning at ~1100rpm each. My typical workload consists of running 2 Windows VMs simultaneously on a Windows 10 host. I initially used the pre-set thermal paste from Corsair pre-applied to the copper-block and idle averaged ~104F. Disassembled, cleaned, and added the Conductonaut and now seeing idle temps average 98F, with temps dipping as low as 89F. Room ambient temperature is 72F.Threw up some Prime95 testing and prior with the stock thermal paste, I hit 157F after 10 minutes. After 10 minutes with the Conductonaut, maxed out at 149F. Both radiator fans were spinning at 1260rpm, pump at 2420rpm; the fans were set at a 'performance' level of 'Balanced' within the iCUE software. I set the performance-mode for the fans at 'Extreme', they both started spinning at ~2150 rpms. After 5 minute the temp bounced between 141 and 143F. For the last 3 minutes, temp hit and sat at 149F. The CPU of all cores was bouncing between 3650 and 3700 MHz. iCUE reported the water temp at 30.8C. For another 5 minutes I let Prime95 continue running. Temps did not change.For anyone who has ever messed with Gallium in its liquid form will know what to expect from messing with Conductonaut. Try to pinch Gallium (or Conductonaut) in your hand and it'll just pop out the side...the same thing will happen when you assemble your heatsink base to the CPU block; which there is a reason the instructions say "apply a pin-drop" and [try] to spread it out. Put too much on and it'll spit out the sides! Don't put your heatsink on slowly and it can actually splatter out the sides as well. Take your time and be patient while trying to spread the liquid metal around - it will naturally glob-up and stick to the supplied Q-tip at times. Try your best.For a little pin-hole application, the results can be quite impressive! For my system, I do not plan to de-lid anything (no point for the CPU since AMD uses Indium solder between dies and heatsink). What I get out of this are some degrees cooler temps running and also longevity, not having to re-apply thermal solutions every few years due to the thermal solution drying up and/or losing its thermal conductivity efficiency over time.THINGS TO CONSIDER:Use the supplied Q-tip to spread the liquid metal around the heatsink as it's quite compacted unlike regular Q-tips that give off some fibers.A teeny-tiny application goes a long way! Also, make use of the additional supplied adapter-tip to suck up any excess application.Keep the plunger open-end and pointed up until it is over where you will be applying it. The liquid metal can fall out and splatter all over, even a little droplet!The liquid metal is very reflective and shiny. Try to examine afterwards with a flashlight after the heatsink is applied if any of the application plopped out the sides - I was able to see a shiny reflection just under the heatsink that I sucked up and cleaned (before plugging and turning system on).Be careful when moving your computer chassis. Any excess that is not spotted and cleaned up could fall and bounce around in your chassis during transportation.Wear latex/nitrile gloves if you mind your hands staining; if you get some liquid metal on your hands they'll be gray for a little bit.

I ordered this over a year ago when I bought a used Razer Blade Pro 2018. This laptop is notorious for running at its thermal throttling point basically any time it's running anything remotely intensive. I put Kryonaut on it when I got it, but it still hit 90C on the GPU and throttled. I finally decided to take the risk and apply the liquid metal Conductonaut paste. I already knew how to disassemble the laptop so getting to the heatsink was no problem. Cleaned the old paste with acetone and a paper towel, then used the included alcohol wipes to further clean the surfaces of any remaining paste, leaving them with a nice shine. Applying this paste is very different from conventional paste. Using the micro tip, the liquid metal comes out and forms a blob. You kind of have to press the liquid metal into the surface for it to start to take hold, but once it starts the rest can be brushed into a thin, shiny metal layer that evenly covers the die. I then put more on the mating copper heatsink surface. This took more force to get it worked in, but it left a nice shiny layer where I wanted it. I gently set the heatsink back in place and tightened the screws.Booted up the laptop after reassembly and fired up Overwatch. I was surprised that the GPU didn't immediately spike to 90C, instead hovering around 80-85C. Not a great temp but if it's not throttling I'll at least see a performance boost. Then I fired up Destiny 2. I started getting massive frame drops in between smooth 120fps gameplay. Turns out that by cooling the parts well, they'll try to throttle up and draw too much power, causing the power supply to reset and the laptop to drop into battery mode. This cycle repeats and causes lag spikes. Note that this is NOT the paste's fault! It works so well that it uncovers another flaw with this laptop's design. The laptop almost seemed to rely on thermal throttling to keep power draw under the power supply's limit. Fortunately, I knew about Intel XTU and MSI Afterburner. I was able to undervolt the CPU and GPU and turn down the CPU maximum and boost power until I no longer saw the battery mode drops. The result? Laptop runs cooler, quieter, and faster than it used to. I love the design of this laptop outside of its major power and thermal flaws, so I'm happy to have both at least sort of under control now.
