ThermaPAK HS15A HeatShift Laptop Cooler for Laptops Up to 15 Inch (Black)

Currently using an air cooled pad:I do a lot of intensive computer use on my 13 inch Macbook Pro and the laptop gets really hot and the fans whines. I have a Cooler Master Notepal X2 Notebook Cooler R9-NBC-4WAK-GP which has an active USB power 140mm fan under a metal grill below the laptop. I believe this is an awesome airpowered cooling solution, but its a bit bulky and too large for a 13 inch laptop. It does work well, but also needs to be using usb power and thus draining your battery. But the targus air cooling product also isn't great for macbooks since the mac usb connection is on the left and the targus usb port is on the rear right, and the cabling between them is unwieldy.Two Heatshifts work just as well and don't need power:I tried out the heatshift 13 and it is sized perfectly for a macbook pro 13. The heatshift actually seems to perform on par with the aforementioned aircooling solution, but the caveat is that you need two of them that you swap in and out every 2 hours or so. (I would like to try a software temp monitor and can update this review with more scientific settings - please respond if you know of a free one for a mac.) The pad has some crystals in it that get soft - its easy to tell when it is not working well anymore and you need to swap in your second one. The good part is that once the two hours go by, the first pad's crystals have hardened and are ready for a heating beating again!Tip - rotate a single heatshift pad for longer use:A tip is that the heat coming from a macbook is primarily in the left rear, and this is where the crystals soften first. The macbook heat appears to melt the crytals throughout the pad, but the ones closest that area soften the most. You can rotate the heatshift pad and get the harder crystals in contact with that area to use one pad for longer, although eventually you still would need two for heavy computer use (software development, gaming, video editing) for more than two hours.Recommend, especially suited to Macbooks:My rear internal Macbook Pro fan does not turn on now using the heatshift and it stays amazing cool. This product is well suited for macs I think for two reasons: macs cooling is primarily by conduction to the aluminum casing, with the air fan being for backup cooling. As long as the macbook is not hot, the fan wont come on and drain your battery. Since the heatshift contacts the entire bottom surface of the mac it can easily remove this heat via conduction. Also, macs don't have any air intakes on the bottom. I don't think that pad would block an air intake on a dell for instance, since it has a dimpled egg carton like surface, but at least this isn't an issue for macs. I don't think I will use an air cooled solution again. I highly recommend this product, especially for aluminum macbooks. Also, you might think bigger is better and want the 15 inch for your 13 inch macbook, but you don't need it and I don't if it would make a difference since the surface of the heatshift with the crystals need to be touching the laptop to work.

Laptops (particularly certain makes and models) just get too hot. It's unfortunate, but it happens. There's no real good solution if you're actually sitting with it on your lap. I've tried five or six different fan-based laptop coolers, and none of them has done the job as well as I would like. They either are too fragile (falling apart with minimal use), too weak (i.e., don't cool enough), or a host of other problems. I have one fan-based one that works great, but it's all metal (so too heavy to carry around) and isn't designed to sit on your lap, but rather on a desk.All that being said, the heatshift thermapak does the job as well as any of those other options that I've tried, and it has the advantage of being nearly indestructible in comparison, plus lighter, silent, and pretty effective at cooling the machine. That being said, it will only cool for about an hour or two of heavy use, though I've found that if I rotate the pad, it moves a cooler spot of the pad to the hot spot on my laptop, so that's a viable strategy, I think. Once the crystals in the pad liquify, you don't get much cooling from it, though it does still protect your lap from the heat of the machine. The thing is, you just chuck it in the freezer for a little while, and presto! It's all frozen up again and ready for action. I even use it in this way (freezing it) when my body gets overheated. I just put it behind my back and it's a very refreshing blast of coolness.So yeah, laptops get hot. It's just something that happens, and there's no real good way to get around it other than lucking out and getting a machine that doesn't get hot, or you can get one of these heatshift pads. At the very least it won't break, and after going through five or six broken fan-based cooler pads, that's enough for me. Handy thing, too, is that they come in different sizes. I have a widescreen 15-inch laptop, and the 17-inch sized one was perfect for me. So keep that in mind.

I had a laptop cooler with a fan that was several years old. It's rated highly on Amazon and worked pretty well while it did work. The problem is, the power cord stopped fitting into the receiving end properly so I'd have to tape it ~just so~ to get it to power on at all. Not only that but the edges were really sharp so it really wasn't made for sitting on a lap.I saw these fanless coolers and I liked the idea of them. Some of the bad reviews nearly scared me off but for the price I figured it was worth a try.I have an HP Pavilion g6 and I manage to run Walking Dead, Borderlands 2, and some other games on it. I use this pad to cool the PC while I'm gaming because it runs extremely hot and I'm worried about damaging my old hanging-in-there laptop.So far, it works really well. I game for hours at a time and it takes a good amount of time for the crystals to melt. I rotate the pad every once in a while and it works just fine. It doesn't keep my laptop super cool but it keeps it out of the danger zone and that's all I really wanted. I use CoreTemp to track the temperature and this pad still keeps my laptop 20-30 degrees cooler than it would be without the pad.I tried the tips people suggested about putting it in the freezer just as an experiment and I have no idea how they get that to work at all. When you put your hot laptop on the cold pad, the pad starts sweating then your laptop gets all wet. I don't see how that's helpful. You don't really need to put it in the freezer anyway. If you use it for a few hours, let it sit overnight, it's just fine for the next day. So maybe not the best for people using it ALL DAY for work but it's good for a few hours of work or gaming.
