How am I supposed to tell if the fans are on? I don't see anything spinning and I don't hear anything but my laptop seems to be cooled a bit?

You should still be able to hear the fan, if you're in a noisy environment, then place your hand either on the front or the back of the unit and see if you feel air flow. Lastly, you could just plug it in, turn on your laptop, but not set your laptop on top yet and just visually verify that the fan is spinning.

This unit is very quiet. There's also a blue light that turns on when the unit is running. There's only 1 fan blade in the middle of the unit. Using the blue light emitted by the unit you will be able to observe that there is a spinning fan blade in the middle. I have used this unit since September 2014 and it has worked great. My old laptop is known for overheating hence the reason I bought this unit. There were several occasions that I've left the laptop on overnight, in the morning the laptop was still cool to the touch. I would buy another one of this when a need arise.

This cooling fan actually send air out of the front of the fan--you can feel it if you put your hand there. And while quiet, I can still hear my fan.

Very easy, one as you said, the fans should spin, and creates quite a breeze, but it glows purple when it is running, there is a small light in the fan housing. Make sure you have the USB cable plugged into your laptop to a USB port that supplies power. I love my cool master.

I hear minimal sound from my desktop computer, and I don't believe any of it is from the card or its fan.

Verify the fan direction, u can see it by the indicating arows at the side of the coolers, both should have the same direction. Verify if u are using the low noise adapter it slows down the speed of the fan.

I usually do not notice any fan noise. Once in a while you'll notice it briefly, then its right back to silent.

I do not know but would like to know if there is something. I don't see anything on my fan that I could plug in

Do you have any internal fans? If so are they blowing out.....not sucking in.

It was not noticeable. I don't recall any sound coming from the cooling fan. that said, It didn't last a week before it burnt up. I sized the PSU to more than double what was needed for this build. I replaced the PSU with a Thermaltake Smart 630watt Power Supply bought locally as the return time had expired. The Thermaltake has performed flawlessly and powers the AMD Phenom 2 x4 960 3.00 ghz Processor and the AMD Radeon HD6800 video card with out even the slightest studder. If you decide to purchase the Raidmax Hybrid make sure you install and run within the return policy time constraints or you'll be left holding the bad part at your cost. It was not noticeable.

Nancy, after inserting into computer, make sure both the buttons next to the plug on the back are pushed in. This turns on all the fans. Let me know. Mine works great.

No. Idles very silent. Even under normal usage I cannot hear. My fans mounted on PC case are louder, and they aren't very loud themselves.

i own one i have never had any issues with the cooling fan, but there might be a defect.if you are setting the laptop on a hard surface and have an issue then there is a problem, but if you are setting it on bed,couch,clothe any no hard surface, that is the problem.check the cooling fan and the vents if they are clogged with dust vacuum all the dust of see if that helps, might have a defective part.

No light, there is a fan... but there is no noise, I actually have trouble knowing if it is running.

Honestly I can't hear it above the other fans I have in my case, and those are made to be silent as well. It's like it's not even running.

must be a malfunction...the one I just got makes no noise, nor the one that came with my laptop made noise...get a replacement!

Heh. Dead silent.Why? the fan is not running! Ever! There is a switch in the back for ECO mode. Unless the power supply gets hot, it does not spin the fan. Since I have a GTX980 with its lower power draw (Haswell o/c to 4.3GHz, air cooled), the power draw has never been enough to make the fan spin that I have ever seen. The fan is on the top so the heat can go into my case through the fan mesh and get sucked out by my case fans. Works well and the top of the power supply is barely warm.

No, I don't have that problem. I never noticed a fan running until I read this email. Now, I can hear a slight hum occasionally. But nothing you should ever notice. Yours is not right.

The fan is not loud at all, it's a very quite Laptop. The Laptop will get warm if holding in your lap for a long period of time.
