Many people have a hard time keeping their laptops cool. This can be a difficult task if you don’t want to carry around a large cooling device. That is until now, ThemaPAK recently came out with their own laptop cooler, however this one has no fans, and doesn’t use any electricity.
- Comfortable, lightweight and flexible for on-the-go performance
- Organic technology uses no power so it extends battery life
- Listen to the noise-free operation of the innovative fan-less laptop cooler
- Outperforms competitors with an impressive 9 degrees of uniform heat reduction
This laptop cooler is very small and lightweight. It is also flexible enough that it could easily be rolled up or stuffed into a small bag (possibly your laptop bag).
The key feature of this laptop cooler is that it is completely green, and I am not talking about the color, this cooler does not use an ounce of power. This is not only good for the environment, but it is also good for the battery life of the laptop (some coolers plug into the laptop for power).
Because it doesn’t use any power it also doesn’t have any fans. This means it will be great for quiet environments like an office.
ThermaPAK makes the claim that the HeatShift laptop cooler provides up to 9 degrees of uniform heat reduction. We will see in the tests if it lives up to its claim.
The design for the HeatShift is very simple. The cooler is simply a square mat that you place your laptop on. Inside the mat are a bunch of crystals that melt when heated. These crystals are what draw the heat away from the laptop. The nice things about the crystals is that they reform when the heat is taken away so that it can be used over and over.
The mat comes in three sizes (13″, 15″ and 17″) and several colors.
ThermaPak sent me a 15″ laptop cooler and I wanted to find out how well it worked. The test is fairly simple, put my 13″ Toshiba laptop on the mat and get the CPU really hot. I used a program called prime95 to get the CPU really hot and I used SpeedFan to measure the temperatures. After a 30 minutes SpeedFan reported the temperature of the CPU at 93°C. This didn’t seem as cool as I thought it should be, so I let the laptop sit for a while and I ran prime95 again, but this time I didn’t use the HeatShift cooler. After another 30 minutes I checked the heat and it was at 88°C. At this point I thought it was interesting that the laptop was cooler without the pad. So what could be wrong? Well the first thing I thought about was that my laptop is only 13″ and I had a 15″ mat. Another possibility is that somehow the mat is restricting the airflow for the CPU fan.

So I tried the whole process again, but this time with a much larger laptop. I happen to have an 18″ ASUS N90 so I put the cooler under that and again ran prime95. Since the laptop was so much bigger than the pad I strategically put it under the CPU so that it would be in contact with the hottest part of the laptop. This time SpeedFan registered the heat at 76°C. This seemed a lot better, but in order to know just how much better I had to run the same test without the cooling pad. So after letting the laptop cool down I ran prime95 again without the pad. After another 30 minutes I checked SpeedFan and it said 70°C.

So the problem must have something to do with how the airflow gets blocked. The HeaShift pad has channels that are suppose to improve airflow, but when the crystals melt the pad flattens and those channels loose their effectiveness. I imagine that the HeaShift pad would work really well with laptops that don’t have fans.
Each time I tested the mat I felt the crystals to see if they had melted, sure enough in all the hot spots the pad was a lot softer. After removing the pad it took about 30 minutes or so for the crystals hardened back up.
On a more positive note, the HeatShift pad did a great job protecting my legs from the burning heat from the laptops. No matter how hot the laptops got I never felt it while the HeatShift pad was on my lap.
So I think this pad is a really great idea. There is a lot of potential for heat dissipation technology like this. Even though it didn’t work very well in my tests I recognize that my laptops are probably not the ideal test subjects. If you have a laptop that does not have fans, (or it doesn’t draw in heat from the bottom) then this would be ideal for you. With prices ranging from $27 to $34 this is not going to hurt your wallet. If your laptop does have a fan that draws in heat from the bottom then we hare going to have to wait for ThermaPAK to address this problem.
