Should the fan in this power supply always spin or only on high loads? Just got it, the fan never spins, is it broken?

Oh definately yes the fan in this power supply should always spin, because it is not thermally controlled. That is a hazard. It may damage your computer also if the power supply overheats and causes a fault. Please return it immediately.

Under those conditions, it would seem broken because I would know if it was on by the fan.

So is mine. I think that's just the way it's designed. Having the fan thermostatically controlled doesn't imply that the fan should necessarily be off at no load.I run mid-power radio transceivers with this supply. It's pretty apparent just listening to the fan speed whether the radio is idle, transmitting at 5W, or going all out at 100W.

There are 2 power modes on this card. If you look on the card, you will find a little toggle switch. In one position, only the middle fan will spin until the card reaches a certain temperature, at which time all 3 fans will spin. Move the switch to the other position, and all 3 fans will spin all the time.

The fan is intermittent depending on the temperature of the inverter. For example if the inverter is connected to 12V but there's no load (i.e. nothing to be charged at 120V) the temperature of the device should be low and the fan wouldn't be required therefore it won't spin.

The fan stays on until the powersupply cools off --- not necessarily 15 seconds. If it's really "indefinitely", then it's broken.

I've never experienced it. Failures happen - RMA it. My main desktop has 8 of these fans in it with zero failures (on 24/7, for several months). Good luck with the replacement!

Yes it has been fixed at least in the one I bought. No whine or any noise for that matter, sometimes I wonder if the fan even works. This is truly the best power supply I have ever owned and it is extremely efficient. I noticed a 32Watt drop in power usage after in installing it. Migrated from a PC-Power & Cooling PS measured by Kill-A-Watt.

Mine works well, fans are very loud. They sent me replacements haven't installed yet...

I am actually using a 300w PSU and everything works just fine for the past week (i7-4770, 8G ram, two HDs). But don't try to take my word and keep a 300w psu for long bc it's supposed to be dangerous to your equipment. I've ordered a 500W PSU and will replace as soon as it arrives.

No, I am sorry I do not. As I have had my fan for no more than 4-5 months, it is still functioning without issue. Best of luck to you!

I've used mine full power for nearly a year now, and there is some signs of oil build-up on the cover. the real issue is the fan bearings failing. actually, the real issue is getting a fully-functional product back from MSI on an RMA. I'm on my 3rd attempt at it, and it all started with a minor inconvenience of the fans not starting, they needed a push to start.

You might be pushing it, depending on the other hardware your system has to keep powered on. I'm running it with a 500 Watt XFX Bronze rated and have no issues.

The internal fan is broken, same with mine. Opened it up and its a cheap computer fan. I replaced it for 4 dollars at a computer store and it works. If you're under warranty, send it back or take the risk and replace the fan.Good luck

No, I don't think the fan turns off at lower loads. It's a very quiet psu that I can barely hear.

I believe the power supply is made by Logisys, but I don't have the unit here where I can examine it to confirm. Others have reported problems with the PSU, but I haven't had any issues yet. I'm only using my system occasionally so it hasn't been stressed hard yet. I figure if it does go out, I can replace it easily so it was a non-issue for me. Still the cheapest price on a tower case that I could find.

Sorry. I got a defective fan and so returned it. Didn't run it for anywhere near that length of time.

Hello Debby, The short answer to that is no, I have had two of these PW3500s and apart from the cooling fan which is very quite they make no noise, even on full load.John.
