G-M2HP04-F

I put this on a Crucial T705 4TB Gen5 NVME Drive. Using a passive heat sync, this drive idled around 50C and would hover in the low 60C range during typical usage. Installation was straightforward, and all the provided parts were good. Moving to this heat sync and setting up a fan curve, the Crucial NVME Gen5 drive now hovers around 43C, and runs around 50C during moderate use. That's a 5C+ difference, which is good. The fan on this runs up to 8000RPM and is inaudible at all but the top speed setting. The fan curve (using FanControl) I setup runs the fan at 25% for anything over 40C, and 50% for temps over 50C, ramping up to 90% of max fan speed. So far, so good. Everything works exactly as I would expect.

Received this heatsink today and installed, I would give this product 6 stars if such option exists. My recently installed Samsung 970 EVO Plus SSD was getting up to 65 degrees Celsius under load. With GRAUGEAR heatsink installed, it has dropped max temperatures to 40-45 degrees Celsius under heavy load. It seems to work well enough for a 20°C difference. This heatsink performs effective dissipation due its design. Two heat pipes draw in more heat fast and has fan driven air flow over the aluminum fins. I would recommend getting better thermal pads as the ones they shipped with are fine. But if you are going far with your cooling, you are definitely want to get higher performance thermal pads. As for heatsink fan, I noticed that the fan is running at full speed and the noise is a bit loud. The instructions show that it’s PWM fan and the speed is controllable. I set the fan controller to PWM from my bios, and it appears to be working and I can’t really hear this fan over the others in my case afterwards. Overall, it is easy to use and works pretty well. Highly recommend.

I ended up returning this because it wouldn’t fit with my RX 7900 XTX in my mid-tower application. So, if you have a mid-tower this probably isn’t for you unless your graphics card is setup with a vertical mount to allow room for such a thing. The quality appears to be very good and would probably have provided what I wanted, but I don’t notice a difference in performance - heat range is find without it and I don’t plan to overclock my ssd.

Very cute and small cooling for M.2 devices, the fan is extra small, so small I think it'll make too much noise, it's a bit too small I eventually did not install it because the excellent passive cooling on my mobo overtakes it I think.

I added additional M.2 drives to my high-performance gaming system. One of the three M.2,s in my system is under the GPU and has the build in heat sync, the OS M.2 is under the motherboard aluminum heatsink. The third M.2 (where all the games and data reside) shows in Samsung Magician that the Graugear heatsink, (it is more like a heatpipe radiator) keeps the 3rd M.2 running cooler than my other two M.2s. I plan on adding a second Graugear heatsink to replace the factory motherboard M.2 (where the OS resides) aluminum heatsink. The M.2 under the GPU has the factory Samsung heatsink. If I move my GPU to a vertical mount in the future I will add a third Graugear. So far I am impressed with the drop in temp this has provided.

Works great!

Does cool down NVME, but I had to add extra heat tape to make the parts touch the Heatsink and only get 5 to 10 degrees f on a good day. Better than nothing at all. I will say the NVME slot is right above the GPU and so is in a bad spot for air flow. The main issue is the work to get the heat sink to meet with the chips so that they can work.

Was very easy to install the fan on the heat control fins is very nice touch and with down loaded program from the manufacturer was veteran easy to convert my small main drive (256 gig) to the new 4 gig card thank you very much for easy installation and OS transfer
