انصح فيه 100%

Our home has a Linksys WRT32X wireless router which is passively cooled, meaning that there is only a large heatsink without a cooling fan. While this is great for absolute silence, it does affect temperatures quite a bit. I have installed OpenWRT on the WRT32X for more control and features over the router and this includes temperature monitoring. On idle, the router stays at 92c in an ambient of 30. Take note, the router is placed in the open in the TV console, so it's not like it is closed up in a cabinet with zero ventilation. On maximum load tests, it can reach a maximum of around 110c (!!). Temperatures like this would significantly affect the lifespan of electronics so I am compelled to do something about it. Here is where I decided to get these cooling fans to help reduce temperatures to more sensible levels. I wasn't expecting what a difference it could make. I simply placed the fan on the top of the router where it sucks out the hot air from the router. Idle temperatures dropped from 92c to 64c. You can take a look at the temperature graph I have included. You can see when I plugged it in and the temperatures starting to decline gradually. I tried reversing the orientation of the fan such that it blows cool air into the router instead of sucking hot air out of it, but there didn't seem to be much difference, so I just let it suck the hot air out. The fans themselves are very easy to use. It is powered by a USB port, and the router conveniently has a USB port that I'm not using otherwise, so I plugged in the fan there. There is also an inline speed controller that allows you to set it to off, low, medium and high. I noticed that if I set it on low, the controller gets just a little warm, while on high it is cool. I'm guessing there's some kind of resistor in there that reduces the speed of the fan by diverting some of the electrical power to heat instead. Speaking of the fan speed, even on the high setting, it is still fairly quiet and moves a generous amount of air per fan. The fans come in a set of two, so I'm using one for the router, and the other for general ventilation to keep air moving around. The fans themselves have rubber feet and a metal grating in front to prevent accidental contact with the fan blades. The rubber feet also provids some distance between the fan and the device it is cooling so that air can pass through more easily. Overall, this is a really good buy and helps so much in keeping our electronics cool and extending their life.

Acquistate assieme al suo controller per il raffreddamento di un sito amplificatore all'interno di un mobile. Davvero sorprendente la differenza di temperatura all'interno, si accendono automaticamente al raggiungimento di una determinata a temperatura. Consiglio assolutamente questo prodotto.

I don't always right a review but was so impress by these fans that I to write a few words. I use these on top a Denon X3400H receiver that only has about 2.5" of space left above the AVR well in the TV unit, so not much airflow even though theirs plenty of space for air flow on the sides of the AVR like most receivers these days theirs no internal fans, so the hot air just dissipates out the top of the AVR naturally and if your units in a TV unit odds are its gonna run quite warm to the touch. These fans work amazing! simply place them on top your AVR (infinity logos facing up) to pull the hot air out of your unit and it will stay nice and cool to the touch. The fans rubber isolation feet are a nice feature, as well as the built in metal fan grills/dust shields (little touches like that along with its ease of use and fair price was the reason I want with this infinity fan set over making a DIY setup using spare PC fans) and the ease of use/versatility is a big plus, being that these are USB fans you can plug them either directly into your AVRs USB port (so they power on with the unit) or into a USB power block plugged into a wall/power-strip and you can simply use the controller to turn them off when not in use or just run them switched on all the time... personally I never use my AVRs USB port so I just plug the fans directly into it and being that I only have a front USB port on my AVR, to keep things as clean as possible I choose to run the cord under the AVR tucked behind one of the AVR feet and out the side of the unit, twist tying the excess wire which leaves the controller nice and handy beside my AVR. I was worried that with the fans on top of my AVR that there wouldn't be enough space left to actually allow the fans to circulate the air out side of my TV unit... there's likely only about 1/2" of space left above the fans but to my surprise even on the low setting they keep my AVR vary nice and cool for hours... vary silent fans and vary efficient I haven't really had the need to even go above the lowest setting to keep my AVR cool, 90% of the time its low and odd times i'll set it to med or high to really exhaust any stagnant hot air that might be inside. Overall I highly recommend these for the price they're a must to keep any of your expensive electronics that run hot nice and cool... its a small investment to prolong the life of your much more expensive gear.

Ürünü ses sistemime ilave soğutma sağlaması için aldım ve gerçekten etkisini hemen gösterdi. Çift fanlı versiyonu en hızlı kademede bile rahatsız etmiyor ve üfleme hızları da gayet tatmin edici. Mataryel tasarımları kalitesini belli ediyor.

Probably the most efficient USB fans out there. Good to cool AV or server racks that are not in their dedicated rooms (which is really what most people have to work with). There should be more AC Infinitys!
