The MSI GT76 has an insane number of heat pipes for a laptop

The GPU and VRAM alone eat up six heat pipes whereas many competing 17.3-inch gaming laptops may have just three or four heat pipes total shared between the CPU and GPU. If you're looking for a laptop with actual overclocking abilities, then the GT76 will be the one to beat.

One of the biggest challenges to designing a gaming laptop is the cooling solution. Having a super sleek design like the MSI GS65 or GS75 often comes at the price of noise, heat, or both. Some laptops like the Razer Blade Pro 17 or Asus ROG G752VY have resorted to vapor chamber cooling for better cooling per unit volume, but such an approach adds significant weight to the overall unit.

We recently checked out the new MSI GT76 and popped open the bottom panel to see what upgrades would be available only to find the longest network of copper heat pipes we've seen on a 17.3-inch laptop. Together, the CPU and GPU have a total of eleven heat pipes in addition to the large dual fans toward the rear. In comparison, competing laptops like the Alienware 17 have just three copper heat pipes in all for significantly warmer core temperatures when under load as detailed on our review on the system here.

We also commend MSI for separating the CPU and GPU in terms of cooling so they do not share any of the same heat pipes. This approach is common on Clevo designs as well, but it's a rare sight on consumer laptops. For enthusiasts, the independent cooling between the processors means the CPU or GPU can be overclocked without impacting the temperature of the other — much like on a proper desktop PC.

Still, the GT76 is one of the louder 17.3-inch gaming laptops we've tested despite its massive cooling solution. Running Witcher 3 induces a fan noise of 57 dB(A) to be louder than the competing Alienware Area-51m. There's definitely room for improvement in this regard.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
