All the tests we ran produce a good amount of data, but determining whether or not those test results tell us anything -- and what -- was another issue.
Each of our three laptops has its own unique factors that impact how effective external cooling can be. In the end, we boiled it down to five numbers: the change in external temperatures, the change in internal temperatures, the change in processor performance, and two sets of numbers for gaming performance.
Two things are clear. First, laptop cooling pads do offer varying degrees of effective cooling. Both internal and external temperatures were effectively lowered, with internal heat levels dropping by as much as 30 degrees Fahrenheit when added up across multiple tests and averaged across our three laptops.
The overall average was a 13 degree drop, but some laptop coolers were closer to a 1 or 2 degree change. Second, you are likely to see a very slight performance improvement as a result of this cooling. All of the pads we reviewed resulted in better performance on average in all of our benchmark tests. The problem is that the performance gains are extremely small.
Processing performance, for example, improved by less than 2 percent. In Dirt 3, which can be run using integrated graphics, we saw improvements most of the time, but the inexpensive HP Pavilion x actually saw frame rates drop ever so slightly a reduction of less than 1 frame per second on every cooling pad we tested. Both the HP Envy 17 and the MSI GS63VR Stealth Pro saw improvements gaining up to 20 frames per second but were already producing frame rates that were smoothly playable, so the difference in experience will be minimal.
GPU-intensive performance in games like Rise of the Tomb Raider, on the other hand, saw improvements on most of the cooling pads, but those improvements never amounted to a full additional frame per second, let alone the sort of substantial changes one might hope to see with gaming performance. Sorry, gamers. We also saw fairly similar noise levels across all 12 of the cooling pads, with noise levels ranging from 48 to 55 decibels. In our lab, which has an ambient noise level of 40 to 43 decibels, that was loud enough to be heard when near the operating cooling pads, but never so loud that it was a distraction.
A regular desktop PC will usually produce around 40 decibels, while 50 decibels is closer to the noise produced by a refrigerator. If noise level is a concern, models with adjustable speeds may be able to run quietly with slower fan speeds. All of this is not to say that nobody should ever buy a laptop cooler. If you flip your machine around you will notice vents on the bottom of your laptop as well as rubber "feet".
These "feet" serve a dual purpose, the first is keeping your laptop stable as you use it, the second is to elevate it slightly so that air can circulate underneath. When used on a table to any hard flat surface, it's fine but when used on a bed or any cloth surface for that matter, the vents get significantly blocked and your device heats up more than it should.
By that logic, the simplest thing to do would be to just elevate your laptop slightly to let air flow more naturally, right? The Hustle. Well, that is exactly what notebook coolers try to do. These devices are placed between your laptop and whatever surface it might be resting on, allowing for better ventilation of air to the bottom side of the laptop.
Additional fans help to make the exchange of air more efficient, or so the theory goes. The people that make these notebook coolers tell us that this is why you should go out and spend your hard earned money on one of their devices.
Most modern laptops are designed by company's that have spent thousands of man-hours figuring out how to deal with heat. It is why heat vents are placed in places where are fingers don't usually travel and in places where they won't be obstructed. It is also why heat sinks and fans are designed distribute air in a particular way. By and large, adding an expensive notebook cooler to the mix does very little to aid your laptop's own cooling systems. Most laptops these days will let you open the bottom panel without voiding the warranty.
All you have to do is open said panel and clean your fans to ensure that they are dust-free. It may seem daunting to apply but it works wonders and with guides like these , it is really easy.
Basically, thermal paste helps keep your core components cool through the use of a paste that is often made from zinc oxide and silicone. All you have to do now is make sure that your laptop is, especially when on a cloth surface, somewhat elevated and you will be free from buying and lugging around heavy notebook coolers.
I then tried it without the cooler and the temperature jumped up by all of one degree to 94 degrees Celsius.
