ACIDALIEM.2 Heatsink,SSD Cooler for Pcie NVMe or SATA M2 2280 SSD Cooling with Fan

I have to say, I've very pleased with the ACIDALIE M.2 Heatsink. I looked up multiple NVMe coolers. This one had many good reviews. They weren't wrong.Build quality:The whole heatsink is heavy and appears to be well built. I was actually surprised at this, and tried very hard not to drop it on my motherboard.Noise level:The fan is silent. I've cranked it up to max speed 8500+ RPM and still couldn't hear it. I have it plugged into a fan PWM header on the motherboard so it'd be easy to adjust the speed (verses using the manual fan controller I added to my case). I decided to run the fan at 70% with gradual increase to 100% as the CPU heats up. I can't hear it anyway, and could have used 100% all the time, but thought it might last longer this way.Temperature impact:Using the "heatsink" cover that came with my motherboard with the NVMe drive in the M.2_1 socket, temperature was around 46 celcius when PC was idle. Switching to the ACIDALIE heatsink and my temp dropped to 40 degrees celcius according to the Samsung Magician software. But wait a minute, my x570 motherboard (Asus Dark Hero) has a second M.2 socket that's far enough away from my heat-generating graphics card. So a day later, I moved the M.2 drive to the M.2_2 socket (it has the same specs as the first M.2 socket). As I type this, the drive is reading 37 degrees celcius. On a side note, these numbers are in Summer during a heat-wave so I'm hoping the temp will be better come winter.Final thoughts:Best $30 bucks I spent in a long time. I did rotate the heatsink 180 degrees so the fan is blowing in the other direction, but thats just a personal preference.

Visually, makes my pc look robust. Everything works, and temps are kept nice and low, while remaining nice and quiet!

The media could not be loaded. I was on the cusp of returning this item for the semi false advertising. With their including thermal pads I was not able to get the side screws on. I believe the top and bottom thermal pads being around 1mm is too thick. However I had a spare 0.5mm thermal pads lying around. With the bottom bad being 1mm and top now being .5mm I was able to press it down enough to get the screws on the side. The next issue I had was the pipes not clearing the m.2 connection slot on the right side. I had to jiggle it a bit to get it in to fit. Luckily with the provided screw it at screwed in fine (stock mobo m.2 screws was too short). I was very happy with the performance though. My passive coolers pushed my gen 4 ssds to their limit 50-70c. Now with my stress testing they capped out at 60-61c. There is a lil hum but its worth it to protect your hardware.

My motherboard: Gigabyte x570 aorus masterTemperatures:Gigabyte x570 Aorus master original cooler -------> idle: 44 C , on maximum load: 65 CACIDALIE M.2 Heatsink -------------------------------> idle: 31 C , on maximum load: 45 CFan: PWM Fan RPM is to high, but there is no sound, it reaches 4500 RPM and its silent.Quality: The heatsink fence is thick, it gives you the quality feeling.Included thermal pads: I did not fix included thermal pads; because it feels its like a gum, it was so sticky to it's protector film. I used ARCTIC thermal pads instead.The thickness of the thermal pads is 1mm .

I bought this because my M.2 drive was above the video card and it got so hot it damaged the drive. I put this on a new m.2 drive and it seems to be working fine. Only time will tell.

52 F to 39 F very nice with 990 PRO

UpdateThe fan has begun to make noise after two weeks. The noise comes and goes. At times the fan will slow down and almost stop. To prevent this I had to set the fan speed manually to 35% so it doesn't get the rpm where it makes noise then stops. I can't get in touch with the vendor for a replacement fan so it looks like a return is in order. I modified to 3 stars because it does keep the drive cool. Without the noise it would be a 5 starI have two NMVe locations and two drives in my PC. The OS is on a Samsung 970 EVO Plus 2tb and the other is a 970 EVO 1tb. The 2tb was running 50 degrees at idle and the 1tb 40 degrees. I put this on the 2tb drive in the location shown in the 1st photo. The graphics card was close and didn't exhaust heat to the drive but it did restrict the airflow the cooler fan could generate. The idle temperature of the drive dropped to 40. I then swapped the drive locations to give the fan a path to move air. The 2tb drive with the cooler is now idling at 33 degrees. This is much better than the static heat sink I have tried that only provided about 5 degrees of benefit. To check my work the 1tb in the restricted location stayed at the 40 degree so the reduction I see on the drive with the cooler is 100% attributed to the cooler. I am running fan control software and don't hear the fan until it gets to the around 70%. For me at idle my fan is running much lower than that.

Does a good job of keeping temps down, well built, I like it better at $24.95.
