So, after 10 years on an i7-860 based system, in mid 2019, I purchased a new computer with the new at that time, Ryzen 9 3900X. When ordering this machine from a boutique, I chose a thermal compound upgrade for the thermal compound between the 3900X and the Cooler Master ML120L AIO cooler that the boutique used. The upgraded compound turned out to be this Cooler Master MasterGel Maker product.Fast forward to 2021, and for no good reason other than "Fear of Missing Out", I was able to get a 5950X and replaced my 3900X. So I purchased the same Cooler Master MasterGel Maker product from Amazon when doing my CPU upgrade.So Cooler Master has a video on Youtube showing how to use the applicator to apply thin "stripes" of compound across the surface of the CPU heat spreader as opposed to the pea size glob that you hope gets spread out evenly as you ratchet your HSF or pump onto your CPU. This looked like a better way to cover the heat spreader evenly and it looked stupid simple.Well, when I applied the compound as shown in the Cooler Master video, my experience was not quite as precise or graceful. I chalk this up to being naturally inept and I did not pull the motherboard out of the system since I had enough clearance to do the application of compound in the PC chassis. All said and done though, I did not get any compound on components and even though it took me 2 attempts to reseat my ML120L block, this product appears to work.So my only real benchmark to see if this stuff is "working" is that before removing my 3900X, I used the CPU-Z utility's bult in bench tab and ran a cpu stress test on all 24 threads of the 3900X for about 15 minutes. I had the Asus Armory Crate app up and just watched CPU temps. It sat around 60 C.Note that 3900X and 5950X are TDP rated 105W CPU's even though 5950X has 4 more cores and 8 more threads. So after swapping in the 5950X, I performed the same Stress test with CPU-Z's bench tab albeit upping the thread count to 32 from 24. Again, after 15 minutes I sat around the same 60 C temperature range.Now granted, I do not know how CPU-Z 's Stress utility compares to Aida64 or Cinebench or even real multithread workloads, however, after about a week and a half now on the 5950X, the machine is stable, and as far as "fan noise" and temps and overall just listening to how hard the AIO cooler is working throughout the day while using the PC, it seems just like it did with the 3900X.I am typically working remotely 5 days a week and use my PC to remote desktop into other machines. So it is typically on 8 hours a day doing low stress tasks. After hours, I play games on it and it doesn't "sound" like it is working harder when on the 3900X.So in the end, is it the MasterGel Maker that made the difference? Or am I just not working the system hard enough to stress my AIO cooler. My take away is that I am on par with what the 3900X was when I initially got the system in 2019.Lastly, the aforementioned AIO cooler is only a 120mm cooler and I perform no overclocking and I also have PBO disabled. I do have DDR4-3000 memory with the XMP profile enabled but honestly, I am not stressing this machine enough to justify the 5950X nor the 3900X I upgraded from.I do plan to use more of this compound as I intend to put the 3900X into my son's B350 based motherboard upgrading from his Ryzen 5 2600. Maybe I will post an update when I perform that upgrade.For now though, I do recommend this product.I was skeptical at first, but this paste out performed kryonaut!I had Kryonaut on my 3090 GPU before, but with this CryoFuze temps dropped by 10 degrees C !!! in comparison under same loads and conditions. this is my new go-to! I highly recommend it!It's a little tricky to apply, temps to stick to the spreader it comes with, so instead I used the squish method to apply without spreadingI've seen a lot of recent reviews of the newer 2020-21 edition of the MasterGel Maker Ultra-High Performance Thermal Compound noting that it is "dry" and therefore, defective because it is difficult to spread. To further exacerbate the issue, it also appears that there was a formulation change from the 2019 edition to the newer 2020-21 edition where the thermal paste consistency of the newer 2020-21 edition is similar to that of a stick of warm bubble gum as compared to more traditional thermal paste compounds, which are much easier to apply (e.g., Noctua NT-H1, Gelid GC-Extreme, Arctic MX-4, Artic Silver 5, etc.). But unfortunately, it appears that Cooler Master did not adequately inform their customers of this new formulation and how to best apply it.However, a quick search on another online retailer revealed that according to Cooler Master (See Newegg Reviews and Manufacturer Response on this exact same product), this paste is intended to be thick like a stick of bubble gum. So in light of that response, I gave it a try as I am optimistic that the long term performance will hold up well particularly for GPU applications. In the past, I've tried many thermal compounds on GPUs (e.g., Noctua NT-H1, Gelid GC-Extreme, Arctic MX-4) and typically, they have lasted between 6-8 months before dry out and the GPU load temperature climbs to 5 to 10 C higher than a fresh thermal paste application. So I thought perhaps Cooler Master might have the right idea here with their newer 2020-21 edition because thermal paste can't dry out if it's dry already.So, I applied this stick of bubble gum in a tube by: (1) squeezing out a little bit at a time, (2) pushing down on the surface to ensure what little came out stuck to the surface (e.g., surface of the GPU die), and (3) moving one-two millimeter across the surface. Steps (1)-(3) were repeated until the entire surface was covered, albeit with some moderate difficulty. Once done, this product does perform well, roughly just as well as Noctua NT-H1, Gelid GC-Extreme, and Arctic MX-4 on my overclocked MSI Duke 1070 ti (+120% Power Limit, +175 Mhz GPU, and +450 Mhz RAM OC). So far (3.5 months since application) the performance of MasterGel Maker has stayed fairly consistent, i.e., 72 to 75 C at 100% GPU load with Furmark and 60% GPU fan speed with ambient room temperature between 22-26 C. Hope this helps!Bastante mala calidad, no sirve para consolas, aplique 3 veces para una xbox one x y a los 3 días empieza a sobrecalentarse de nuevo, 3 veces la tuve que aplicar, en cuanto cambié a una pasta De mayor calidad y un poco mas cara Grizzly Kryonaut los problemas terminaron a la primera aplicación, ventilador silencioso y no se ha apagado en meses de uso, esta es definitivamente muy chafa no la recomiendo, lo barato sale caro.Good thermal paste, for your cpu.. quite self explanatory really.. and even came with a plastic square cut out.. that your sposed to put over the cpu housing.. I didn’t bother with that as I’m an ex freelance computer by trade..It works great for a heat sync but since I only needed very little I didn't want to waste the rest of it. I spread the rest on some crackers because if it made my laptop cooler it should do the same for me, boy was I disappointed.Very good product. My trusty core 2 quod was heating up and removing the old paste and adding this thermal paste really improved my cpu and now even the fans have almost become silent :)very effective. saw an instant improvement in cpu temperature which enable me to significantly overclock the processor without issues. (please note my previous paste was in need of replacement)
