there are a review from a costumer who buy this product :
Currently, I own a 2008 Dell Latitude E6400, which always gets the "blue screen of death" from over-heating. Keep in mind, I often crossed my legs on my lap, allowing sufficient airflow to the cooling vent. I honestly thought notebook coolers were a niche product. Having had experience with the awful Targus PA248U1 Chill Mat, I had virtually given up on a notebook cooler being able to solve my alarming heat problem. However, I perused Amazon's site for a few hours and did my homework. I soon discovered the criteria that my prospective cooler needed to fit:
-College student's meager budget
-Solve severe laptop over-heating problem
-Style wasn't important. An ugly/effective cooler is better than vice versa.
-Casual web-surfing/movie-watching/paper-writing use. I don't need a gaming cooler, since I don't leave my laptop on for like 6-8 hours at a time.
-Ability to be used on the lap. I do lots of homework on the couch at my school's study lounge.
-Good Warranty when Amazon's return period expires
-Preferably one fan
-Preferably with an extra USB port
-Preferably a company that specializes in desktop/laptop cooling
-Most important: Something that will LAST a long time, more than 1 year.
Front-Runners
-Zalman NC-300U
-One fan, not-bulky, great workmanship, extra USB ports and fan control...man this had it all! While the price was a bit of a stretch (I still could have afforded it), it did not look lap-friendly at all.
-Antec "Classic" Cooler
-The three year warranty and trustability on the market since 2003 was really, REALLY tempting. However, the sole reason I did not choose this was that the wire adaptor looked very flimsy.
-X-Pad
-No fans, no electricity, cheap price, highly durable, effective rubber stoppers and beating out other coolers in a Cnet.com test made this very tempting! However, I have heard the customer service is non-responsive, the new rubber stinks and some users have reported the heat is transferred to their legs. Most of all, cooling ability depends on the laptop's design. Since my laptop's vent is on the side and not on in the center, I was skeptical. By the way, here is the link to that Cnet.com test:
[...]
-Thermaltake Massive23 LX
-This, in my opinion, was the most similar to my final decision. However, it looked really bulky and didn't seem suitable for lap use.
-Targus Lap Chill Mat AWE55US
-I really wanted to give Targus another chance, no hard feelings. It looked really roomy! However, it was reputed to not last longer than a year. After looking at the price against the reliability, I decided against it
-Cooler Master Notepal U2
-While the fan-positioning, price and #1 best-selling status made this a front-runner, I decided against this for 3 reasons: the fans weren't known to last long, the wiring was exposed and it wasn't good for lap use
-Logitech Cooling Pad N100
-The silent operation, rear-intake and how it was designed specifically for the lap was really tempting. However, the material looked flimsy, it was reviewed to not last long and the airflow was not adjustable. I needed a really strong fan.
First Impressions
When I opened to box, I was immediately struck by how much sturdier, classier and compact it looks in person. I was reading the reviews and I noticed some say its bulky, but for my needs, I don't find this an issue. I carry a leather briefcase in addition to my laptop backpack, so I'll just stick this in there so it doesn't get crushed.
Performance
I used a free program called CPUID Hardware Monitor to record the temperature with and without the cooler.
Without and wireless on (casual web surfing): 108 Degrees Fahrenheit
With (high speed) and wireless on (watching movie online): 100 Degrees Fahrenheit
With (high speed) and wireless on (casual web surfing): 98 Degrees Fahrenheit
With (high speed) and wireless off: 94 Degrees Fahrenheit
Pros
-The aluminum "mesh belly" dissipates heat effectively. I'd also imagine that it would make using a can of compressed air easy.
-Cool Light-up effect. Not only does it look space-age, but it lets you know that the cooler is on.
-On/Off Switch. As I have been told, this is more valuable than you think because detaching the USB cord while the fan is on could possibly shorten the cooler's life. I would turn it off first before disconnecting it
-Fan Control. Its stiff (indicating great build-quality) and responsive. At a touch or two below max level, it's still very quiet!
-Having one large fan instead of two smaller ones is rather nice. Not only is it quieter, but distributes heat evenly. Even though my laptop's main vent is located on the left side (as opposed to the "windier" center of the cooler), it still cools very well!
-Pop-out legs for height adjustment
-2 USB ports, one to connect your laptop and one to replace the USB port you gave up connecting this cooler. That means you don't give up any USB ports at all to connect this cooler to.
-Detachable USB cord is well-constructed. If you don't want to use up your laptop's battery, you can plug in the USB cord into an MP3/Cell phone charger.
-Unlike some other (especially more high-end) notebook coolers on the market, this can be used comfortably on the lap. While it does not have a mesh underside, the plastic is surprisingly comfortable and does not conduct any heat to my legs.
-1 year warranty
Cons
-Doesn't look easy to take apart to really clean inside the nook and crannies.
-Perforated edges don't hold my laptop securely. The crannies between my laptop and battery pack thankfully provide a good anchor to the cooler. A rubber stopper on the surface (like on the Cooler Master Notepal U2) or pop-up legs on the bottom (like on the Logitech Speaker Lap Desk N700) would have been nice.
To buy or not to buy...?
For day one, I'll let the performance speak for itself. However, I will keep you posted if anything arises.
Thanks for reading and good luck on your search!
