Cooling pad how does it work

A blowing fan may have some benefits, but noise can be a real drawback. Since we tested each cooling pad at the maximum fan speeds available, our noise testing also addresses the loudest noise level it can make in normal operation. 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.

It would also make sense to see how much of a difference in noise the pad would make without interference from the laptop fan. On average, the noise level rose from 40dB to 45dB, which is still in the quite room territory. Please also keep in mind that this pad is close to 2 years old. A newer pad will achieve even better noise levels. From our tests, we can see that laptop cooling pads actually do work and help to lower temperatures.

And lower temperatures translate to better performance and less throttling. There are a lot of ways to lower temperatures and improve performance , however, a cooling pad is one of the easiest and least complicated ways to do that.

There are a lot of advantages to using a cooling pad. Choosing a cooling pad can be a bit tricky, and you will need to keep an eye out for a few things:. I have been using the MECO cooling pad for over a year now, and have been satisfied as it fulfills all the points mentioned before. However, it has since disappeared from the market. However, you could get a TopMate TM-3 If you have a larger laptop, then I recommend the Pccooler Laptop Cooling Pad click to check the price on Amazon as it fits laptops up to As you have seen, cooling pads will not break the bank.

So if you do not have one, it certainly will not hurt to have one on your desk for those hot summer days. First, having your hardware run a few degrees cooler is not only better for performance, but for the longevity of the product. So even when I am using a newer laptop, I usually like to have it running on a cooling pad. Another thing to consider is that when your laptop is running cooler, your internal laptop fans do not need to spin as hard, which may reduce the dust build-up around your internal laptop fans and air vents.

How can you blame them? Laptops are now being used for a lot of high performance and high graphics activities that require a lot of processor power and RAM speed. This is why laptops become so hot after continuously using them for hours on an end. Desktop PCs have it easy, as the CPUs come with cooling fans that can reduce the amount of heating to some extent.

However, with technology improving itself every day, there is a similar solution for laptops, which is known as laptop cooling pads. These cooking pads work pretty much exactly like the cooling fans in desktop CPUs.

But the real question is, do they actually work? If you want to find out if laptop cooling pads are really worth the purchase, continue reading this article. Allen Ngo - Lead Editor U.
