It seems like the bigger the load the more the fan runs. It must be temp controlled as the fan goes on and off.

mine is now broke this is the 2nd one - i don't remember. i got a better inverter that is pure sine wave - works much much better but is double the cost. but i think the fan is supposed to shut off - that's what my new one does. these cobras are not very good inverters in my opinion.. the fan should shut off but if it's a heavy load it will stay on. it should be off under no load.

If you go to the website it does state that it helps keep the heat down, thus the fan shouldn't run as much. I have noticed this to be true for my MacBook, but I think the age of your laptop would factor into it.

Did you make sure the temp +/- is set to the temp you want? Every time my power goes off or o unplug it, it resets itself and I have to reset the temp to blow cooler. Also, there is a setting to blow just room air around. Make sure you aren't accidentally on that. Download a booklet and see where the settings should be to blow cool. These things don't have freon, do they??? If so, it could need coolant. When you cleaned it, could you have a loose connection inside somewhere? I've never had trouble with mine, like others seem to. But usually it is because people aren't draining theirs, but trying to use it with it plugged up. And even though they say they'll work that way, they don't. The water must drain. I really love this thing, but using it is complicated.

Sorry to say the fan stays on unit you turn it off. I also was unaware of this till I got it home.

I've had mine for about 6 months. The 2 fans blow directly up onto laptop and you can feel, depending on speed, the air dispersed to sides. Blue lights are quite bright. The remind me of the underlights on cars these days. ; p I keep mine on low speed and adjust the height/ angle on the very 1st "rung". I don't game but I do turn it up when grandchildren come over and use it. I have a Presario notebook. It does get very warm which is why I purchased this. If it did breakdown I would get another just like it in a flat second. Cleaning?. I havent tried to take it apart. I blow it out while running on low with canned air. Hope this helps.

Just bought mine today and turned it on 4 - experiencing a similar problem: Every several minutes the fan will decrease for a second and then go back to normal. It's almost like a power issue, but I don't notice lights dimming or anything else other than the fan noise for that second...

I keep on having issue's with mine too. It does not work well, it keeps on turning off and stop cooling my laptop after every few seconds and I have to tap on the back to turn it on. This product is horrible and I only used mine for 2 times. I wish I could return it to get a refund or a replacement.

Can you be more explicit. I have the same exact fan. The cable has a round plug at one end that plugs into the fan and a usb plug that plugs into the laptop. Are you saying the round plug does not fit into the cooling pad. I cannot imagine that the plug they supplied does not fit. Maybe you should rephrase the question.

Not sure if it only has one fan. It has a button I push when I want the fan to blow faster when gaming. The air coming out is pretty warm when gaming but I don't know the exact temp. To me it doesn't matter. I really like this laptop and it performs awesome.

I don't think it was designed like a laptop where there is no fan speed at all until the processor reaches a certain temperature. Mine runs all the time as well, but quiet with no load, louder with a load. The fan speed change is immediate too which shows to me it is load driven, not temperature driven.

Is there any confirmation from the manufacturer that the fan should be always on or not?My fan does not running at all when I charge my battery. Really afraid that the charger could be getting to hot or burnt out...

there is an on and off switch and if u leave it on and turn your laptop off it will go off automatically and come back on when u turn ur laptop back on. Hope this helps

I agree with Jamieb, However Once the motherboard completes its post the device will continue to monitor the board. But it may not report the problem until you reboot. On a side note being a laptop if a virus has been ruled out I would insure that the fan is operating. And if it is older than 3 years old the thermal paste on the cpu may be getting weak and your cpu may be over heating.I paid $60.00 usd to have fan replaced and new thermal paste applied to a HP G series unit which had the same symptoms. The board did not report the problem. Hope that helps. Good Luck a competent honest technician will do wonders.

Make sure the fan is not blocked with dust and is working, Mine works fine after I removed the plug on the end and wired it directly to the outlet. I went through 3 of these in 6 months but removed the plug and it works like a champ.

Yes, the fan is cooling down the system, esp the light, I think. I find the instructions for turning off the machine confusing. I let the fan run for 10 min or so, check that it feels cool, then pull the plug. The machine works great except for the OFF snag.

Sorry I cannot help you there. When I bought mine I am not sure if the fan was defective but when I turned it on it bearly, I mean bearly blew any heat, so I sent it back to Amazon and did not get a new one.

It stays on all the time if it's plugged in, I think. There's no on/off switch. It might have some type of internal shut-off when the temp. hits a certain point. I don't know.
