I got this for a 17" laptop - an older Win7 model - that has been gradually increasing in average operating temperature and fan speed as it ages. It works just as I'd hoped. According to the laptop utility, my CPU temp is now running at "40%" instead of "60%" and the internal fan speed is much lower as well. More than that, the hard-disk drive and memory chips all seem comfortably cooler as well. I used to feel the heat radiating through the keyboard, now it only gets mildly warm after hours of continuous use - and I don't even need to run the cooler at full speed. The cooler has a very useful speed control on the side, with an "off" position included. The blue LEDs on each fan also dim when the fan speed is reduced. Take note, however, that at full speed, the cooler will draw up to 900 milliamps from the USB port into which you plug it - that is the standard for USB 3.0. If you have a USB 1.0 or 2.0, they are only rated to supply 500 milliamps, and you will be disappointed in the cooler. This is also true for an external USB charger/adapter if you go that route (as I do). Make sure your adapter can put out the full 1amp (1000 milliamps) and you will be happy. I had a cheapo unit that didn't manage to produce as much as it claimed - and it would not keep the cooler running properly and it also got quite warm. The 5-fan cooler is quite lightweight - but seems strong enough for holding the laptop and the top surface grill is stamped metal with a few reinforcing bends artfully pressed into a pattern on its surface. I've not been using it long enough to make a call on its durability - but for now, it seems great to have my trusty Win7 laptop working without as much heat. I'm hoping to keep it as long as possible! Read more

I have been happily using my older Windows7 laptop (my main workstation) with this cooling pad for a few weeks with no AC in the room. The room temps have been over 90 at times. This laptop cooling pad has kept the temps on my laptop well within acceptable functioning temps. I hate when the laptop gets so hot that it slows down to cool itself. That has not happened, though it was happening at the start of summer when I was without a cooling pad, when the laptop fan would get loud, indicating higher speeds and the computer would function at less than top speed. The two main considerations I had were the size and the function. My ACER ASPIRE 5733Z laptop is a 15.6” widescreen, measuring 10”x15”. The only cooling is through a bottom 1.5-inch diameter grill (with an accompanying fan) on the left back side that pulls room air and pushes hot air out the side. The N11 TECKNET Cooling pad measures about 11”x15.25” and the top surface sits 1” above the table level when flat (the back is raised to 2.5 inches total height when the feet are out). The vented surface is about 10” deep by about 11” wide. There are 4x 90mm corner fans and 1x110mm central fan. They PUSH air onto the laptop, which suits my laptop as this increases the airflow through the vent. When the fans are running, you can only detect a slight movement of air at the vented surface with your hand, but if you cover the entire surface with tissue paper, it lightly lifts the paper. A normal piece of paper is too small, like a hand, and the air goes around it, seeming to create a pull. Anyway, I find that back of my laptop is cooler and the running temps stay low when I use the cooling pad. I find that I can easily use the cooling pad on a desk or on my lap. On the lap with bare legs, I can feel the pull of the air. I noticed that I usually sit with my legs to the sides of the corner ports and can feel the air on the inside of my leg. Sometimes I shift and I think I block the fan port, but the air appears to pull harder through the other ports. The pad itself has rubberized, non-slip feet which work well. There are also extendable back feet to angle the cooling pad for a more natural working angle (adding 1.5 inches to the back height). The back feet easily swing out and back with a single finger. The cooling pad has a device recessed into the top surface at bottom that will flip-up to function as a slide block for your laptop. My laptop’s feet have great traction and it does not slip on the pad, but the top of the cooling pad is smooth and would certainly allow slipping without the slip blocker. The pad must be plugged in to USB power (on your laptop or on another USB outlet) to function. A USB cable is provided and, once it is plugged in, there is one spare (USB2) port (two total) on the left side of the pad. The fans have blue LED lights when on. Both the lights and fan speed are jointly connected to a knob on the left side that you can turn to manipulate fan light+speed. The lights do not shut off or on independently and only dim or shut off along with the fans. The fans are whisper quiet and I rarely notice them unless I listen for them. They make a quiet and soft shshshshsh. In the past I had a laptop cooler (Targus lap chill mat) that I used, but it broke. I bought another cooling pad (TECKNET N5 – I reviewed it as well!), but it was too small (14” wide) for this laptop and I have moved the other N5 to under a 12.5” wide laptop that I use. Compared to the Targus, the N11 is quieter and more sturdy, plus there is a spare USB on the N11 to take the place of the one you use to power the cooling pad. The N11 is large enough for my laptop and does the job of increasing airflow and keeping my computer cooler. I am happy with my purchase! Read more

Have had this almost two years now. It still works pretty good. Fan switch started to wear and not always work 100% after the first 6 months, so just leave it on full speed the majority of the time. It has done a good job of keeping my MacBook Pro cool during gaming or heavy usage when doing Bluray Ripping or video editing. Can definitely feel the warm arm getting pushed up and out of the laptop when it is running hot. Other than the fan control having issues, like most of these coolers, the rubber feet come off and require to be re-glued. Just ordered a Rosewill RWNB17B to replace this one with to see how well it works. Probably retire this Tecknet for a PS4 Slim. Read more

When I received the item, I was surprised at how lightweight it is. the construction didn't appear as flimsy either, so I was pretty impressed right out of the box. To see how well it blew air I hooked it up to a phone charger and turned it on. It didn't move as much air as I thought it would, but the volume of air is spread out over a large area so although it doesn't seem very fast when in reality it is moving a large volume of air; and even tiny bits will help your laptop stay cooler because it keeps the laptop from sucking in the air it just circulated, thereby keeping your system cooler. Normally, the air comes out of the laptop exhaust ports and a portion of it will get sucked back through the ventilation system, causing undue heating. The blue lights are a nice and fun touch, but you really can't see them when you put the laptop on the cooling pad. I am using a 17 inch laptop with an expanded battery pack so it doesn't sit on the pad as well as it could due to the pack sticking out the bottom, but it still works very well. Read more
