This cooler is probably the best compared to others with similar prices. My laptop is a msi and already has a turbo fan, that on with this fan as well let's me play games like Civilization 5 on high settings with my laptop barely getting warm.
Totally solid despite my initial misgivings during assembly. It sits at a perfect angle for my wrists.
The size was just right, a bit big for my laptop but works great.
TL/DR: Good product, does like it's supposed to. After adding a nvme to my MSI Camo Squad ( Yeah, I bought one of those in 2017 lol ) giving it new life I was having expected heat issues with throttling regularly. I tried a few different cooling pads however results were disappointing at best. I bought some fans and was going to get out my woodworking tools to hack my laptop desk ( read hospital style mobile tray ) when I seen this cooler dirt cheap with one of the smaller fans looking like it was perfectly positioned to force air into the tiny intakes below the nvme drive. BINGO, dropped from hitting 70c just cruising the hobby forums down to a max of 50c with Steam downloading to the drive, downloading some files for another pc, and CrystalDiskMark 8.0.4 benching the drive. To me, thats a win for 20 bucks and change.
It does the job, better than anything else short of a leaf blower.
