CalinTM Posted April 13, 2013 Share Posted April 13, 2013 Why when i play games from time to time my fan starts to spin for just 1-2 seconds and then stops again, then another time, it's random, starts again for 1-2 seconds and then stops again ?? When i gaming i exceed the power limit when the fan is stopped, then the fan starts to spin and then stops ? Or what ? I remember when i bought the PSU didn't did that.

Corsair Employees RAM GUY Posted April 15, 2013 Corsair Employees Share Posted April 15, 2013 That is perfectly normal. Fan is PWM controlled with respect to temperature and load. The fan spins briefly to push out hot air inside the PSU and will stop is cooling is not needed. Since you have an I series PSU, you can always change the fan profile using Corsair Link SW.

CalinTM Posted April 16, 2013 Author Share Posted April 16, 2013 I dont think is normal for the fan to randomly start for 2 seconds then stop. Also, my wattage in games is about 230W in and out, and in most games almost 180-200W, so then why the fan starts at this low wattage, and starts only for 2 seconds, then stops. Also, the max temp of my PSU after gaming, is 40 degrees, so doesn't go higher. On this combo the fan doesn't have to start. Link to comment Share on other sites More sharing options...

Mine does the exact same thing and it was ridiculously annoying. The solution for me was to manually set the fan to run on the lowest speed (I think it was 40%) in corsair link. The PSU is still almost inaudible at this speed and it doesn't ramp up like it does @ default settings. I'm not sure why they designed it this way but when the PSU fan starts up from idle, it goes well beyond the minimum 40%. This causes the quiet mode to make much more noise than simply running the fan on the lowest setting all the time. Link to comment Share on other sites More sharing options...

If you uninstall CL, does it save the profile? Link to comment Share on other sites More sharing options...
CalinTM Posted April 21, 2013 Author Share Posted April 21, 2013 Well, you say your PSU does the same thing, basically when i play games i have maximum 180W wattage consumption, and it heats to maximum 40 degrees, according to corsair link software, so there it starts to make that fan issue thing, starts in games randomly for 2 seconds then stops, then after 10 minutes/ 20 minutes/ 5 minutes, starts again and then stops. If i am in idle, doesn't do this think. So can anyone, or a staff member confirm what RPM i get on 40% fan speed on AX760i ? When i set it on 40% i get 700RPM, is this right, or should be lower ? And even at 40% the fan is still kinda noisy, is there a way to mod the corsair link software to set it lower than 700PRM, if i could get 400 or 500 RPM it will be perfect. I know the Yate Loon fan is a fan with ball-bearing, but recently i found here a thread with a person having the exact same problem as mine, and if he set the fan at fixed RPM the fan is noisy. So, If the fan will continue to make this cycle at random fan start for 1-2 seconds in games then stops, then repeats, will not broke the fan ball-bearing ? Also, how i should mount the PSU, with the fan up, or down ? (in my case). Link to comment Share on other sites More sharing options...
Faithh07 Posted April 27, 2013 Share Posted April 27, 2013 The fan is noisy here as well when it's running at low rpm it's chirping. Lately noticed that my fan kicks in but only rotates 1mm nothing more. Happens repeately every x seconds. Link to comment Share on other sites More sharing options...
CalinTM Posted May 2, 2013 Author Share Posted May 2, 2013 Ah never mind i RMA-ed this PSU and bought a seasonic platinum 860W, has some san ace 120 fan with superb ball bearing, no noise at all. Dear Corsair, your digital PSU is very fine, the electrical part, but you ruined those AX i series with that stupid yate loon ball bearing fans, they make noise OVER TIME, because the balls inside due to PSU heat they don't get lubricated anymore and start to noise.

I agree, I want to buy a new AX to replace my trusty HX but the regular AX Seasonic made ones have coil whine issues and the "i" variants made by Flextronics have this issue with the Yate Loon fans chirping/squealing. I want to buy a Corsair PSU, really I do, but I am not willing to sit with problems until the underlying issues are properly resolved and communicated to clients Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted May 8, 2013 Corsair Employees Share Posted May 8, 2013 Well these issues you are talking about have been fixed a long time ago and Who makes the PSU is not the issue so dont believe the crap you hear. I would suggest one of the AXi series PSU's. Link to comment Share on other sites More sharing options...
nikk Posted May 10, 2013 Share Posted May 10, 2013 hi i have one psu 650w tx version2 and i have same problem with fan, it starts in the bigining full rpms for 3 seconds and stop, after that i trying to push the psu with occt and prime 95 together but after 15 munites the fan spin up for 10 second and stop again why this happen; my old psu corsair 650w tx the fan spin up continue i think the psu have problem with fan but in the shop replace with one new and i have tha same problem, how is hott my psu as it start psu fan; i play gta iv 5 hours and never spin tha fan, is this normal; Link to comment Share on other sites More sharing options...

Most of our PSUs now are more power efficient than ever and one thing that we had change to gain that higher efficiency, is to regulate the fan operation based on load and temperature inside the PSU. Your system is probably not pulling much load even when under OCCT and P95 or maybe the internal temp of the PSU is not high to trigger the fan to spin continuously. Ambient temp will also be factor here. I wouldn't expect the fan to run all the time if amb temp is fairly low,. it may spin briefly but only for a short period of time, just enough to exhaust warm air inside the PSU.

As long that the sound is not louder than any of your case fans. If the system is stable and you are not having some power issue, I wouldn't worry about it.

JohnOrion Posted March 31, 2015 Share Posted March 31, 2015 Well these issues you are talking about have been fixed a long time ago and Who makes the PSU is not the issue so dont believe the crap you hear. I would suggest one of the AXi series PSU's. This is incorrect. I just purchased one in Feb 2015. At idle with no load and the PSU temp at 37.5, the fan randomly spins up to audible levels (about 1200 rpm) for a second or two then shuts back off. Its annoying as all heck. Change it to 40% always on in the software. Fan runs at about 700-800 rpm .. fairly quiet but ... randomly still spins up to 1200 rpm for no apparent reason. Temps still very low (even lower than the 37.5 since the fan is always running). This is something I will be contacting support on to find out if there is any way of resolving this. I may have wasted my money on this thing. Wish reviewers would have been more verbal about this issue. I didn't find out about it until I had the problem and did a search on it. This is the second PSU that I spend a large dollar on that has basically lied on their marketing. The ThermalTake Smart850M claims to be a "silent" PSU but turned out to be a hairdryer at idle.. worst POS I have ever bought. Now Corsair may get my rating as second worst.

I didn't find out about it until I had the problem and did a search on it. How would a reviewer be more verbal about something that never happened to them in the first place? You seem to think ALL of these PSUs have this problem, yet you had to bump a two year old thread to complain about it. ;): There's always a percentage of failed product in the field. A bad PSU doesn't always mean a dead PSU. It could just very well be a bad fan controller in the PSU. I'd RMA it. Link to comment Share on other sites More sharing options...
