MASSCOOL Shin-ETSU Thermal Interface Cooling Material G751

I used this for my CPU in hopes to get it cooler, and I have damn near the same temps as before. Possibly 1c -2c cooler, but there are other things to consider here. When I opened up the computer, there was fuzz and debris in the heatsink and all around the case it was a little dusty. I have a couple of big intake fans that bring in a lot of dust and hair, and I'm forced to clean out my case every 3-5 months. The 1c-2c difference could be because of the cleaning. In other words, there is nothing special about this TIM compared to some others. That normally wouldn't be a problem, because if it's equally effective, then there's no harm. But this is not "economically reasonable" as one reviewer put it. You get 0.5g of product, and when you compare it to other brands, this becomes a rip off. For the same price I paid, I could have received 3g of a different well known brand. I had Tuniq TX-3 on my CPU before. The product itself is ok...It's only the amount that makes it not ok. I would never buy this again based on the amount you get.**edit 3/7/13** So I still had 0.25G (half) left and needed to do my MSI GTX670 Power Edition Video Card, which was hitting 82C running Crysis 3, with no overclock. I removed the heatsink on the card and saw that the paste looked a little messy and uneven. Cleaned it all off and applied this TIM and IMMEDIATELY saw a 10C difference. Crysis 3 now maxed out at 72C with no fan profile. Here is what I've concluded so far. If you are replacing average TIM with this stuff, you will get excellent results. If you already have good TIM and good temps, your results may vary. If you are expecting to just bring down temps by 1C-2C, then I think you can achieve that. I was expecting at least a 5C difference from my CPU and when I didn't get it, I was disappointed, but when I got a 10C difference from the video card, I had to re-think this review. I'm adding a star, but not giving a 5 because of the amount. If you have two jobs to do and you mess up on one, you would have to buy more.

So I used this first and got pretty good temps using prime95 (I think it got to low 70s). I ended up moving the position of my cooler and cooler fan so I put some arctic mx-4 and the temps went down to high 60s (68-70 was where the temperatures floated). So both work pretty well and I would just buy whatever is cheaper. The only thing is that the mx-4 has a 8 year guarantee so if you plan on not messing with cpu/cooler/buying new parts, it may be better to go with mx-4.

Quality "old-school" Shin-Etsu G751 is my personal preference even for modern processors. It has been around for many years and used by various manufacturers and OEMs for processors, power transistors, and numerous other thermal-intensive components. It is a chemically homogeneous mixture and electrically non-conductive. Applying at room temperature can be a little difficult depending upon usage, but slightly heating the application syringe in a cup of warm water is a quick trick to improving spreading and workability if required.For those buying pastes solely according to thermal conductivity ratings, please note a 2018 study entitled "Impact of Thermal Interface Materials for Thermoelectric Generator Systems" - available via a quick web search. G751 is listed in the study, but more important IMO is one particular finding regarding the litany of tested thermal interface materials: "Thermal conductivity above 1 W/mK for TIM does not have a significant decrease of the difference in temperature across TIM." The reason? A thermal paste clamped under pressure typically is for filling slight imperfections and other microscopic voids in surfaces, not for slathering in thick layers, so apply accordingly for best results.

I just used this with a new AMD Ryzen 5 2600X (on an MSI X470 Gaming Plus mobo) and an old Corsair Hydro H60 liquid cooler. I followed the pro tips about cleaning the dried-up paste off the the old liquid cooler, warming up the syringe of Shin-Etsu paste for about 5 minutes in a small glass of just-boiled water, and applying only about a BB's worth (roughly 5mm diameter) of paste to the center of the CPU before attaching the cooler.Worked like a charm.My idle temps so far have been between 36-42C. Highest temp I've seen while using VR (so far) is 56C.So glad I used this with my Corsair instead of the stock Wraith cooler(and it's pre-applied paste) that came with the CPU.EDIT: So, running a video encode with all cores firing at about 97% with boost clock up just slightly past 4GHz took my CPU temp up to just 72C--fully acceptable to me, given that the chip is rated to 95C (max).

there was only just a very small amount inside the applicator. i didnt have enough for my cpu and it cause my temps to be very high idling!!! the temp was 58 degrees celcius i have a amd a8 6600k richland with a msi a75ma-e35 motherboard. and now i have to buy more thermal paste. i want my money back!

I switched to Shin-Etsu compounds a number of years ago as even early on, the performance in cooling was widely praised. It is non-conductive, which is another plus.Shin-Etsu compound is typically thicker than the AS compounds that most PC builders have grown accustomed to over the years. A trick to resolve this issue is to soak the tube in warm water prior to dispensing it.There's a lot of debate about whether to spread thermal paste onto the CPU in a thin layer, or to place a dab roughly the size of a grain of rice on the middle and apply the heat sink and let the pressure of the heat sink even the thermal paste out.In my experience and benchmarks, the grain of rice method remains the best, even with a thicker compound such as Shin-Etsu. Applying a thin layer tends to lend itself to improper applicatoin and leaving behind too thick a layer of thermal paste which reduces the thermal transfer from CPU to heatink.This is a great product and if you want peace of mind that your CPU and heatsink are cooling optimally, this is a great product to start with.
