havit HV-F2056 15.6″-17″ Laptop Cooler Cooling Pad – Slim Portable USB Powered (3 Fans), Black/Blue

Effective device at a “cool” price.
Great price, surprisingly good product. I always find it odd to see an item get 20 5-stars and then 20 1-stars. Possibly some got a an item that came off the production line faulty OR perhaps they travel with it and packed it shabbily, let their 2 year old use it as a Frisbee, etc. I guess there is truth in “YMMV” I think this item looks very sturdy. I plan on keeping it in one place. I have no kids and live alone. Sooo Hopefully, it will still be working fine in several years. Disclaimer is that I just received it today (one of the nice things about Prime membership is getting that IUPS delivery on SUNDAY. Nice surprise. My laptop is OLD – old meaning probably 7 or 8 years old and has dated technology. Dual chips and at this point in it’s life, it runs pretty HOT. I am retired, have insomnia and often doze off at 4 or 5AM with computer running, so its on pretty much 24/7 I am amazed it is still running and also know it contains a lot of info that is either very difficult to back-up/store, or just too much of a hassle to spend that much time doing so (and I’m a bit naïve about doing that.So, I plan on buying a new one in a month or so and just want to do the best I can to keep guy running until then. Heat is a big enemy of computers, especially when they start getting as hot as mine has been (prompting me to get the cooling pad, but really, it’s a goo idea to use this from day one). It will greatly increase the life and performance of your computer and it’s components. This cooler is QUIET, even more so than I expected from many reviews. The blue light? Some found it annoying, but it wasn’t at all to me and I actually think its really a nice feature that lets you know it is running, since it runs so quiet (and my hearing not the best). Well, if it runs so quiet, it can’t be putting out much air, right? Nope – nice steady stream of air – not hurricane force, but quite sufficient. I opened the box, put it under my laptop on my lap and decided to read up on the 13 pages of questions people asked about it. Just to see how it well it would work. Didn’t do any gaming, but did have a number of other programs open and viewing like facebook, some web surfing, reading mail, etc. After several hours where it would normally been almost too hot to touch, it was surprisingly COOL to the touch. Good deal! Very happy with those results and I’m thinking about getting another unit for my PS3 and/or as a back up.A couple of tips: some complained the short power cord seemed to come apart fairly easily. Most cables tend to be that way, especially those on equipment that is moved around much at all. What I do with virtually every power cable phone/USB, etc, is to take a length of electrical tape and wrap both connector ends a number of times at a length of a an inch or so centered right at where the cable meets the connector. A lot of cables have “stress relief” built into them, but I’ve had these fail as well. The tape reinforces it and helps prevent frequent sharp bending and eventual failure. I am also going to power the cooling pad with an external USB 2.1A charger so as not to draw down the battery or increase any additional heat. Probably an overkill on my part, but I have a 7 port AC powered USB charger that I use for phones and other devices. The pad IS slick and while the “feet” angle it a bit (which makes for better air flow), it also causes my laptop to tend to slide off. I plan on putting several rubber “bumpers” on the bottom of the laptop to keep it stable. Short story long, I am very pleased with the device especially with the cost and that it truly does keep my computer running cool! Would certainly recommend to others, I think you’ll be well pleased. Wish I had bought this years ago.

Slim, lightweight, and effective
I use a high performance laptop for work and it puts out enough heat to warm a small conference room, if left flat on a desk/table it will go into thermal overload.I needed something practical that I could fit in my laptop bag and wouldn’t double the weight of it (and quiet enough it wouldn’t be a nuisance in meetings).I’ve been using it all day, everyday, for about 3 months now and it works great! Small enough you’d hardly know it’s there, keeps my workhorse of a laptop cool enough it doesn’t feel like the person sitting across from you is in front of a space heater and not any louder than the built in fans of the laptop.Simple things like having a physical on/off switch and the USB pass through are nice to have as wellThis was exactly what I needed, hoping it stays running this well for at least a couple years.

I bought this laptop cooler for my router (which gets really hot and becomes a bit unreliable) rather than my laptop. The cooler is about twice the size of the router but I have some other devices attached to the router which also get hot, so I put those on the remaining free space. The good news is that even though the air flow from the fans isn’t particularly powerful, it’s more than enough to cool my devices. Result. The bad news is that although the cooler is fairly quiet (about 22db at six inches from the cooler, according to an App I downloaded on my phone) it’s still loud enough that it annoys me. This is a problem because my fibre broadband socket is in the lounge right next to where I sit, so that’s where the router has to be, and it drives me mad. The obvious solution would be to reduce the voltage being supplied to the fans so they run a bit slower. While scouring Amazon for the requisite parts, I stumbled across the DollaTek USB Fan Speed Controller (£5.99 for three). This does exactly what I need without me having to take the cooler apart (or do any soldering)! In fact it does more than I need because it not only allows you to reduce the voltage (to reduce the noise) it also allows you to increase the voltage (up to 12V! to increase cooling). As a further benefit, when the fan controller is set to MINimum, the LED’s on the fans don’t illuminate. Handy! Then, as you increase the voltage the fans speed up and the LED’s gradually get brighter. Nice! Without the fan controller the cooler produces 22db of noise at six inches. With the controller on MINimum the cooler produces just 16db at six inches, which is much quieter! (I can still hear it when the room is silent, but not when the TV is on.) With the controller on MAXimum the cooler produces a whopping 44db of noise at six inches, but the fans move MUCH more air. Any gamers who need a lot of cooling might find this useful. (Regular users probably won’t though because the noise is too loud.) As we all know, energy costs have gone through the roof recently, and currently stand at about 36p per kWh. Without the fan controller the cooler consumes about 3.5W, which is almost nothing, and would cost me about 3p per day if I left it on 24/7. With the controller at MINimum the cooler uses less than 0.1W (less than 0.1p per day) and on MAXimum is uses 11.3W (10p per day). The final question though, is whether the cooler will still cool my devices when the controller is set to MINimum… and the answer is… yes! Job done! 🙂 To use the controller, all you do is plug the controller into your power source (laptop USB socket or USB mains adapter) and plug one end of the male-Type-A-to-male-Type-A USB cable (supplied with the cooler) into the female socket on the controller and the other end into one of the female sockets on the cooler. Done. BEWARE THOUGH – if you’re using the controller YOU SHOULD NOT USE THE SPARE USB SOCKET ON THE COOLER TO POWER ANYTHING ELSE, because it won’t be receiving the standard 5V power that a USB socket should have. Your device either won’t work (if the voltage is below 5V) or could be permanently damaged (if the voltage is above 5V). I also don’t know if running the cooler above 5V will reduce the life of the fans. Do so at your own risk!

No es un secreto que a todo portatil le llega su San Martín en cuanto a los problemas de calor se refiere, sobre todo en verano. El prolongado funcionamiento y la compresión de espacio en su vientre hace que el procesador y el disco duro alcancen temperaturas excesivas y provoquen malfuncionamiento e incluso el degradado de la pieza (dispersión de pasta térmica, etc).Me decanté por éste modelo, principalmente por su tamaño adaptable a mi portátil de 15,6”, sus 3 ventiladores (mirar siempre que os coincidan con vuestra rejilla de la carcasa para mayor efectividad), y su “ergonomía inclinable” (unos 20º aprox), no resbala y la rejilla mantiene el equipo bien sujeto. Además, tiene un puerto adicional USB para no perder el que ya se usa para su funcionamiento (aunque lo mejor es usar un HUB para ampliar puertos). Es muy liviana y menos aparatosa que otros modelos más robustos que he visto.El resultado es una base que refrigera el interior del equipo, unos 12-15 grados aprox según marca mi monitor CPUID, en rendimiento normal, y unos 8-10 grados en alto rendimiento de procesador y gráfica. Suficiente como para que ventile mejor gracias a la inclinación de la base, y para no “quemarme las manos” al escribir sobre el teclado. Se nota mucho. Además, es ultrasilencioso, hace menos ruido que los discos duros externos que tengo. Cumple su cometido para bajar apenas unos pocos grados la temperatura habitual.Como curiosidad (ni buena ni mala, según gustos), desprende luz azulona mientras está en funcionamiento (tipo “gamer” llegué a leer), que si es cierto no se puede elegir que luzca o no, pero que no supone ningún problema, ya que cuando hay luz apenas se nota, y a oscuras ilumina los laterales de la mesa, como el ratón por ejemplo. Vale, no es ideal si vas a ver una peli por el efecto “ambilight”, pero no deslumbra la vista tampoco. A mi no me molesta.Muy recomendada.

A little bit noisey but very easy to forget the sound of the whiring fans as you work away..great price and yes would buy this again if needed
