Thermaltake Massive V20 Steel Mesh Panel Single 200mm Blue LED Fan Adjustable Speed Control 10"-17" Laptop Notebook Cooling Pad CL-N004-PL20BL-A

I’ve used this fan for a while now, and i really like it. Its large, pretty quiet, and it moves a good hit of air through it. I keep it on when my laptop is on at all times and it really keeps my temps down. I highly recommend this to anyone with a laptop to improve the lifespan on it.

Averaging 6-7°C cooler with the fan. I also can’t hear this fan at all unless the room it’s in is dead silent.

Honestly, for gaming laptops this cooler pretty much useless even at full speed. The fan is not powerful at all, and the effect that this has on temperatures while gaming or doing even regular tasks is almost nonexistent. This is one of the cases where you get what you pay for I ended up buying a more expensive cooler and it is 100 times better than this. Don’t waste your money.

Currently own two of these fans. Have had the first fan about 2 years, and the second fan about a year. Both are used almost daily. Both fans are essentially quiet at their highest speed level. Both reduce the laptop's internal heat, while reducing the frequency of when the laptop's internal fan runs.Neither came with a "Y" cable. Both use only a single port of the laptop they are connected to; and both provide a USB "port" built into the cooling fan's USB connector as show in one of the photos. In my situation, the built in USB "port" is used for the wireless mouse receiver without issue. Thus, the cooling fan's USB connection is for my laptop USB port count neutral.Others have purchased this fan with my recommendation, and have been using them without issue.The investment cost for the first fan, which cost more than the second fan, has been approximately $0.032 per day of actual use. The second fan's cost has been approximately $0.06 per day of actual use. Of course, with each additional day of use the investment cost for utilization decreases. This excludes any consideration for reducing possible maintenance costs and extending the life cycle of the laptops they are attached to. And based on the length of time of ownership the actual cost is even less. In my opinion, cooling fans are and excellent investment.My ownership of laptops dates back to 1994. All of my laptops have been operated while sitting on external cooling fans. The longest I owned one of my laptops was a little over 11 years. It still worked when I gave it away, and it still works today. It has always been operated with a cooling fan running underneath it. (It is on its second external fan.)

Lasted less than 2 years of non-stop use, but who buys this with the intention of running it at max performance 24/7/365 without expecting the fan motors to eventually give out? It worked well enough for me to order another as a replacement. It is fairly easy to disassemble, clean, and reassemble.

Overall it functions. It looks very nice and the blue LED is a nice touch. However, the fan in the pad that I have seems to have bad bearings, there is a constant noise from the fan at all speeds.I use this for work and it is either in a padded backpack with my laptop for travel or in use. Thermaltake is usually better quality then this. It is possible I just have a bad unit.

I was looking for a cooling solution for my Asus AC3100 router and this did the trick. Generally, you don't need active cooling for a router. As long as a router is located in an open area where air can circulate, it'll be just fine. Most newer router CPU's are designed to operate at temperatures between 70-80 degrees Celsius and even slightly hotter with little trouble. The problem I had was that the interior room in which I keep my router is always warm. Even though I keep my router in the open, the ambient temperature of the room drove up the router's CPU temperature, which routinely hit more than 80 degrees Celsius during heavy use (gaming and streaming). That's something the computer nerd in me needed to fix.After see a bunch of fairly ugly hardware hacks, I figured a laptop cooling pad would work. This was inexpensive enough to try out and it did the job. The single, large fan more than covers the footprint of my router and feeds air into the vents on the router's underside. Within fifteen minutes of positioning the router and turning on the fan, the router's idle CPU temperature dropped almost 20 degrees Celsius. CPU temperature now hovers between 49-55 degrees Celsius even under heavy use.At full blast, the fan is fairly quiet. I'll notice slight noise if everything in the room is quiet from about 10 feet away, but it's certainly not overwhelming or disruptive. I've never operated the fan at less than full speed, but you can adjust it. Lowering fan speed all the way shuts the fan off. The unit runs off of USB power, but I have it plugged into its own outlet using a mobile phone adapter. It absolutely can be powered by my router via USB port, but I'd rather avoid the potential interference doing so may create. The LED lights can be shut off if they're not your thing. Note that the entire unit does have a somewhat large footprint and works best on hard, flat surfaces. As with all active cooling fans that suck in air from the bottom of a device, do not place the unit on carpet. That's just asking for trouble.If you have a router that runs a little too hot and your router also is ventilated on the bottom, this will do the trick. Inexpensive, well built, and quiet.
