"Our stress test showed that the heat produced by the CPU and GPU is not transported out of the case fast enough. >For instance, here is a direct quote from their review of the cooling assembly: I only recalled seeing NotebookCheck's review back in August of an almost identical sku Helios 300, and seeing markedly different results here in so far as Temps are concerned.

CPU Stress Testing, CPU Temperature Testing, CPU/GPU Throttling Testing, Audio Ramp Up of Fan Assembly? There were some things missing from this review that seems out of place given the normal processes for Tom's Hardware Reviews. If you’re more concerned with gaming performance, then this probably won't bother you, especially at Acer’s asking price. These display issues may not be deal breakers, but the high amount of inaccuracy could be a barrier if your work needs color accuracy. In particular, you’ll notice errors in reds, greens, yellows, and especially blues and magentas. The Predator’s display has an extremely high DeltaE 2000 of 6.1411. Just like grayscale accuracy, color accuracy is measured in DeltaE 2000, with an ideal display exhibiting values less than or equal to 3. In comparison to the other laptops, the Predator Helios 300 has the highest average gamma point. The ideal gamma point for well-balanced saturation is at 2.2 unfortunately, the Helios display hovers above 2.2 at all brightness levels, and in some cases, nearly reach a gamma point of 2.4. Our CalMAN grayscale accuracy chart illustrates the DeltaE becoming problematic at higher brightness levels. The Helios display has a DeltaE 2000 of 3.1227. The ideal display would have a DeltaE 2000 value of three or lower, at which point grayscale errors are imperceptible. The low blue levels hurt the display’s grayscale accuracy, but not to a great extent. All things considered, the Helios 300 has decent battery life, but it isn’t outstanding compared to its main competition. On the lower end of the spectrum, the MSI GE63VR Raider only provides 78 minutes of playtime because of its beefy GTX 1070 and 51Wh battery, which is embarrassingly small for such a powerful GPU. The tradeoff, of course, is less performance. If battery life is your main concern, Acer’s Aspire VX 15 performs much more admirably by virtue of its 52.5Wh battery and less power-hungry i5-7300HQ and GTX 1050. The Whitebook accomplishes this despite its more restrictive dimensions. However, the similarly equipped AVADirect Whitebook 16K2 delivers nearly 20 minutes of additional playtime thanks to its larger 64.98Wh battery.

It manages to provide over one hour and 30 minutes, due to its moderately demanding i7-7700HQ and GTX 1060. The Acer Predator Helios 300 contains a rather small 4-cell 48Wh battery, so right off the bat, we didn’t expect its battery life to be impressive.
