Why it turns off after only 20 seconds when I use it for a CPU fan?

I will need more information on your CPU fan... I need to know the amps wattage and volts of fan...

The fan is in the "Timer Mode". This can be set from 1-16 hours. If the timer was turned on and the fan was not running at the time, the fan will not start until the timer turns off. If the timer mode is turned on when the fan IS running, it will run until the set time has laps. To get out of this mode, push the MODE key at any time. Look at the fan digital display, by pressing the Mode button, it will show, 1,2,3 this is fan speeds, press the Mode button again and the display will show, A1,A2,A3 this is in the Auto Mode and the thermostat will turn on or off the fan at a given temperature, 1=low, 2=med, 3=high. good luck The fan is in the "Timer Mode".

It automatically changes the fan speed as needed. I'm not sure if it ever completely turns the fan off or if it is just at a very low speed.

the device should have nothing to do with the device not applying a load. maybe try a different pc or perhaps the fan is not cooling down the processor and the thermo switch is preventing the computer from coming on. Maybe the pc switch is no good. if you find out the answer you could send out the response. I am curious as to what the issue might be.

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.

Never have had that problem, would guess it is reacting to high SWR or possibly an heat issue such as the fan not operating, the unit does have thermal shut down which can be caused by high swr or a heat problem.

Yes mine does the same thing. My guess is that my fan wore out because the first few days it was loud and annoying, but eventually stopped. Only then did my computer begin to overheat and shut off when I play certain video games for as little time as 45 minutes.

In the overview it says the fan turns off when not needed. The powersupplies does not put out the heat others do. Best bet for better ansewer go to the Amazon site under the Corsair HX Professional series 750, and look in the overview it will go over it better than I can. THanks for wrightting. Randy PS I relay like mine a lot.

Yes, exact same problem on two fans. Had first one die first week, then a second one after a couple months. If you reverse the direction, the fans turn off for a few seconds, then reverse. If you adjust the speed without waiting for the fans to kick back on, something goes haywire, and it fries the fuse immediately. If you replace the fuse, the fan continues to run, won't turn off or respond to controls, and the fuse blows again. Their warranty service cannot replace the fan, because "They don't have stock"... "Call back in 4 months". If you have one of these fans, give the fan time between changing direction and changing speed. Both fans died in exactly the same way. The fan is great until it fries.

I dont have this particular fan controller. But I dont think it would be wise to ever plug a CPU fan into the can controller. Depending on the Bios or MoBo you have you might be able to configure the fan to adjust automatically.

It is possible that when in backup mode it gets noisy but in normal standby mode with the line voltage such that it is not operating from battery, the fan is not running at all. I never noticed any noise.

At all, seriously, the first few times I was using it, I thought the fan wasn't working.Then I started up a very graphic intensive game (The Witcher 2) just to see if it overheated or anything, and I got no sound and no heat.If I didn't know better, I'd believe it was witchcraft.

I just bought this case as well to a 230v country. I made sure it's switched to the 230v side before doing anything. The fan on the power supply would start, then stop after a few seconds, then start again etc. Same for the CPU fan that is connected. Is it possible all these power supplies are lemons for 230v?

The fan itself should be silent. If you are hearing noise, it may be defective, or something else may be making noise. The second fan is going to help cool the CPU better but shouldn't impact the noise volume.

The fan shuts off immediately. It is a regular bathroom fan. I have a 70 cfm, of this model installed, and it shuts down immediately.

Not sure what you are asking, but we replaced this because the fan for airflow would not shut off.

Yes. When you manually press the fan button on the switch, it will behave like a timer switch shutting off after 30 minutes.
