GDSTIME Quiet 4x 120mm 5V USB Cooling Fan with Variable Speed Controller

Works very well under my asus GT-AX11000 router to keep the router cool and very quiet cant hear it running behind my in the wall

Excellent love it do the job what i expected to do 🫡

I placed this router fan under an Asus BE98 Pro router that is up high near the ceiling and was getting so hot it would occasionally reset under heavy load. I have two 10G connections, 80+ devices and two USB drives so it is under a load. This fan dropped the temp 60 degrees F on the cpu and 40 to 60 degrees on the four radios with the fan speed set just above minimum. The router legs barely fit on the fan as it is almost too big but with careful placement it works fine. Very quiet and very effective.

Got this fan. It was almost perfect for what I needed. Except I needed the fans to blow cold air DOWN. This fan blows air upward. BUT you can dismantle the fan assembly and shoot all the fans upward. Why not just undo the feet and put them on the opposite side? Because they’re pretty cheap and don’t easy rescrew once unscrewed. I actually still had to reattach these once I reversed the fans and had to use loctite to hold them together. It works out great in the end. Oh…more thing…there is no “chassis” just a lot of small meta pieces holding everything together and you have to be VERY careful to dismantle very slowly and only what you must…one piece at a time…or you may have a lot of tiny pieces and it may not hold together very well if any are missing or not properly reattached. A plastic frame or chassis wouldn’t have cost much more to create and would have Mae the process much easier. Otherwise great fan.

I recently had switched from comcast to quantum fiber and was having intermittent connectivity issues. My router and modem are in the closet and ai live in Tucson. I suspected that I was having some overheating issues. This had solved my problem. I no longer have connectivity issues since putting this in place. It isn't the quietest but the video makes it sound like a jet engine. It isn't nearly as loud as it appears. I don't hear it at all with the closet door closed. It has a variable speed but I run it at max.

The using this to keep airflow through my Asus AX11000GT. Can confirm control the speed and can’t hear unless everything in the room is off.

The ubiquitous home Internet router, is usually left running 24 hours a day; even when we are not home. After all, you'll never know when Alexa, Google, or God forbid Ring or Astro, has to tell you something "really important." As broadband speeds get faster, so do the bandwidth demands of the devices we connect to our routers. Whether we own VR headsets, Recast or TiVo units, or even gaming consoles & computers; at some point, we breakdown and purchase a gaming router. Gaming routers are no Raspberry Pi -- as some routers can contain up to 8 CPU cores, which is almost as many as the typical gaming PC or console -- and THEY ARE USUALLY FANLESS. If you were to take a contactless thermometer, and compare the ambient room temperature (when you are home) against the operating temperature of your gaming router; you will typically notice a difference of about 20'F or more. The typical gaming router begins to throttle at 104'F followed by a thermal shutdown at 110'F. Anyone who owns a smartphone has already experienced "heat anxiety," when finding themselves in warmer than usual environments. When we are not at home, the ambient room temperature in the typical house or apartment can be 87'F or more. And this is NOT GOOD for the typical gaming router. The GDSTIME cooling fan(s) have a surface area of 90.25 square inches (9.5" by 9.5"), which is sufficient to comfortably fit under most "dead spider" gaming routers. During operation the fan speeds are synchronized; there is no detectable fan harmonic (beat) noise, and the overall fan noise is well below the ambient noise level of the typical home, even at night. When the fan speed adjustment control is at about 66%, there is only a measurable difference of about 10'F between the ambient room temperature and that of my gaming router. As you can see from my pictures; the cooling unit is meant to be repairable, should the need arise to replace any of the fans. Because of the way the unit is constructed; it contains no built-in strain relief for the fan power cables. I strongly recommend using a cable tie, to prevent "bad things" from happening. Other than that, the GDSTIME cooling fan unit is a must-have for any gaming router installation.

It is nice small adjustable speed fan for my router protect from overheating in the closet.
