Acer Predator Helios 500 Thermal Testing – Undervolting and Overclocking
8750 HC. Be you a pretty decent option for gaming if we're able to properly utilize it for the graphics, it's got the nvidia 1070 and that's the full 1070? No max q here so we're. Looking at a pretty powerful gaming combination, it's also available with the overclockable eye, 989 50 HK CPU so expect different results. In that model, thermal testing was completed with an ambient room temperature of 18 degrees Celsius, it's cold here at the moment, as it's winter in Australia. So expect warmer temperatures in a warmer environment, I'd idol, both the CPU and graphics, were a little warm, as shown by the light blue bar towards the bottom, but that's, just because the laptop was completely silent at idle. As you'll hear soon, the gaming tests were completed with watchdog's at high settings as I find it to be a CPU demanding game, and we can see that the temperatures shoot up in the green bar, but no issues at this point other than running hot. If we manually max out the fans, as shown by the yellow bar above, we actually dropped the temperatures of both processor and graphics by around 20 degrees, an impressive result if we instead go back to leaving the fans on the automatic profile, but apply of minus 0.15 Ev volt under volt to the CPU we're, still seeing a little temperature improvement, as shown by the orange bars again. If we manually max out the fans shown by the red bar, the combination of high airflow and under bolting gives us quite cool temperatures in gaming.
Just to clarify at least CPU under bolting was done here, but this generally affects GPU temperatures. Little due to the shed eight pipes, the stress tests were done by running a to 64 and the heav'n benchmark at the same time, in order to attempt to fully utilize both the CPU and graphics, moving up in the graph and starting with the dark red bar. Where actually power limit throttling on the CPU, with an average of 91 degrees Celsius? Once again, when the fans are manually maxed out in pay, even with the stress test, we're lowering the temperatures by 20 degrees really impressive stuff, but that doesn't affect the power limitations with the fans back on the order profile shown in the purple bar. Even with the minus 0.15 row, volt unbolt applied to the CPU, it was still hitting the power limit and with the fans maxed out and under fault applied in the top dark blue bar we're, seeing the best results under this full load stress test. These are the average clock speeds for the same temperature tests just shown. You might need to pause and refer back to the previous graph to get the full picture. First off starting down the bottom in the gaming results. We can see that once we apply the CPU under bolt the average clock. Speed of the CPU Rises quite a bit closer to the 3.9 gigahertz, all core turbo speed over the 8750 h. So not only does the under vault improve temperatures, we're also seeing improved performance and the increased fan speeds provided just a little boost, as shown by the yellow and red bars.
I wasn't actually seeing power limit throttling in this particular game, but that will vary between games and their specific workloads. Moving up into the stress test results: the clock speeds in the dark red bar are the lowest due to power limit throttling and with the fan maxed out in pink, this doesn't really change anything as it's, not a thermal issue, once the CPU under fault is applied In the purple bar we're getting much better performance on the CPU, but with the fans maxed out, this appears to increase just a tiny bit, so the power limit is preventing us from reaching the 3.9 gigahertz all court overboost speed of the 87 58 CPU in this Particular stress test workload, although it's getting close, I was actually able to remove the power limit throttling in this stress test, with both a to 64 and the heaven benchmark running with the minus zero point. One nine volt CPU under vault, but the stability was a bit dicey. I didn't do in depth testing at this level, as in my experience, minus 0.15. O fault seems to be pretty common with the 87 58 in terms of stability. So the fact that I could go higher here might just be pure luck and may not be very reproducible in every processor. So how does this performance boost actually translate in games in the games tested? The exact same windows, updates, game updates and Nvidia drivers were installed. So there shouldn't be any changes other than the CPU under vaulting and graphics.
Overclocking. The same syrup, one 500 volt undervolt to the CPU, was applied as before. Along with the 200 megahertz GPU core overclocked and 100 megahertz GPU memory, overclocked Pub G was tested using the replay feature and at Ultra settings were just seeing a little 5 percent boost to the average frame rates, but a larger 8 percent improvement at very low settings. Far cry 5 was tested using the built in benchmark and add ultra settings. There was an 11 improvement to the average frame rates and a 7 percent improvement to the 1 lows Rainbow. Six siege was also tested with the built in bench mark and at Ultra settings. There was an APIs and improvement with the under fault and overclocked applied, which increases to 10 percent at low settings, so we're seeing some good performance improvements, although it depends on the particular game in question. Unfortunately, I didn't have enough time to test any others. These are the clock speeds I got while just running CPU only stress tests without any GPU load power limit throttling was always present in this test, even without the GPU load, and even with the CPU under volt applied Intel XT, you showed it sitting on a 45 Watt TDP in a full multi core stress test, and I wasn't able to change this by modifying the values in X to you so I'm, guessing it's, defined at a low level and copy changed. The laptop has a 230 watt power, brick a bit higher than many other 8750 H, laptops, I've tested so I'm.
Guessing it's capped due to the higher powered 1070 graphics. Still, it would be cool if a secured only limit if it was needed. I doubt the CPU needs to be capped, this way in a CPU only workload, for instance, but I guess this just may not be possible as no one else seems to do it either. I'Ve got some Cinebench CPU benchmarks here, and we can see that we get a nice boost in performance with the minus 0.15 air volt under volt applied at the top of the graph. As mentioned earlier, power limit throttling was present in all CPU and Lea stress tests. So we're still not getting full performance here. To be honest, I was hoping for better results and 87 58 without any limits should be able to pass 1200 points in this test with no throttling. So, although single core workloads are fine, if you need heavy multi, core use, you're – probably not going to get the full performance of the processor, but this can be improved by under vaulting. Here are the GPU? Only clock speeds well under a graphical early stress, test, aces. Prejudiced and software lets you apply GPU overclocks easily in two different levels, known as FASTA and Tubber: the faster profile overclocks, the GPU core by 75 megahertz in the memory by 150 megahertz, while the turbo profile doubles this to one hundred and fifty megahertz on the core And three hundred megahertz on the memory, I was able to get a little further improvement by manually overclocking it with msi afterburner, as shown in red, but this will probably vary between laptops as it depends on the particular chip.
I suspect the baked in faster and turbo options, probably work on all laptops, so they probably don't push things right to the limit and stick to the safest side for compatibility reasons. As for the external temperatures, where you'll actually be putting your hands at idle, the body of the laptop is sitting in the low 30s fairly cool while gaming. This increases to the low 40s towards the center of the keyboard as kind of a worst case. These are the results under a full stress test, with a fan on the order profile getting into the mid 40s still not too bad for comparison. This is the same test with the cb1 der vaulted and the fans maxed out back into the 30s, a huge difference. As for the fan noise produced by the laptop while they have a listen to some of these tests at idle, it was completely silent, which explains the wall idle temperatures noted earlier, while gaming with the otter fan profile, it was actually fairly quiet, at least compared to Many other less powerful gaming laptops, which seems to explain the warmer temperatures with the fans maxed out. It gets very loud but, as we saw earlier, the temperatures dropped down a lot. I don't think I've ever seen, maxing out the fans make such a big improvement and you've got the option of setting the CPU or graphics fan speeds through asus prednisone software. So you should be able to find a good balance between temperatures and fan noise that works for you.
Overall, I was really impressed by the cooling solution, but would like to see less power limit throttling in multi core workloads, especially when it can clearly take it in terms of temperatures. The limitation might be in the power delivery. Perhaps there will be something that's improved in a future. Bios update just to be clear. This isn't an issue unique to the Helios 500 I've, seen this in pretty much every eye: 78758 laptop I've tested, but as covered here there are steps we can take to mitigate this and improve performance. These differences in performance shown aren't hard and fast rules. There are different factors which will vary results, primarily the temperature you're running in application of thermal paste and even specific hardware, which comes down to the Silicon Lottery. You may not be able to under bolt or ever clock your hardware. The same as me, it depends on the chip and its specific power requirements, so don't just blindly copy my settings and do some testing to find out where your stable point is for best results. Well, you could probably improve the temperatures by swapping out the thermal paste based on my results here: it's not really required, as shown with the fans going, it gets quite cool, but doing this may mean less fan, speed required to achieve the same temperatures, the thermals aren't. Really an issue anyway, and we start to hit power limit throttling. In any case, this isn't something I can test with review unit.
The laptop needs to work the same way for the next person to receive it. If I go ahead and remove the stock thermal paste and replace my own, I can't put the old pace back, so the next reviewer would experience something different from what you'd actually see with the product and unknowingly report incorrect information due to what I've done under vaulting On the other hand, isn't physically intrusive and as we've seen, it did improve the performance and temperatures in this particular unit. With no downside, once you've got a stable under Bowl it's, a great way to get back some performance if you're running too hot or facing power limit struggling like we were here. Let me know how much of a performance boost you've found by under vaulting your hardware and what you thought of the improvements here and don't forget to subscribe for the full review of the Acer, predator Helius 500 gaming laptop as well as future tech.
