It is not always Fan#1. And it's not always that slow either. Also, it's not always fans attached to the Commander Pro either. Right now, I have all fans set to 100% again. Fan 1, 2, 3, and 6 on the Commander Pro should all be about the same speed. However, fan 6 is 200 RPM slower than the others. Also, I have the 3 fans attached to the H150 set to 100%, but Fan 1 on that is also 200RPM slow. So, this issue seems to change which fan is impacted, and how much that fan is impacted. Also, for clarification, I have the Commander Pro with 6 fans attached: - Fan 1 is a 120MM LL - Fan 2 is a 120MM LL - Fan 3 is a 120MM LL - Fan 4 is a 140MM LL - Fan 5 is a 140MM LL - Fan 6 is a 120MM LL I also have the Corsair H150 AIO cooler, which has 3 fans attached: - Fan 1 is a 120MM LL - Fan 2 is a 120MM LL - Fan 3 is a 120MM LL Fans 1, 2 and 3 of both the H150 and the Commander Pro are attached to the radiator of the H150 in a push-pull configuration. The H150 attached fans are the intake (push), and the Commander Pro are the exhaust fans (pull). As such, I want these fans to match speed to optimize airflow, and that is why I am using the coolant temp of the H150 to control the fans on the Commander Pro.

I'm having an issue with iCUE. On occasion, random fans will not follow the fan curve properly. This happens both with custom fan curve profiles, or with the built in profiles. Right now, I have 6 120mm LL fans connected to the Commander Pro. Since all 6 fans are identical, I would expect all 6 fans to perform similarly (RPM wise). However, even when all 6 fans are set to the same profile, one or two run very slow (800RPM). I have even created a profile called "Manual Max" which does exactly what it sounds like; statically sets the fan speed to Fixed 100%. Even using this profile, one or two fans will stay around 800-1000RPM while the other spin up to 1400-1800RPM (which is also odd that there is such a wide spread of RPM speeds, considering all 6 fans are the same). I don't think its a power issue or something like that, because even if I only try to run 3 of the 6 fans at their max setting, the one still lags behind the rest. I have attached images of this issue. The first is using the Manual Max mode I created and described above. The 2nd is using the built in "Extreme" profile. The third is running only three of the 6 fans at an elevated profile, but still one is basically idling. Any ideas on this? Version information: iCue - 3.21.88 Commander Pro Firmware - 0.9.212

Two months later, Corsair finally got me a replacement PSU. Guess what, the replacement is doing the same thing! First, the replacement was NOT a new unit, it was a refurbished unit. External tape on the box was cut with a new piece installed over it, and the internal serial number tape was also cut. Figured i'd still try it, as I have been running on a backup PSU for over 2 months and have an event next weekend I need my PC ready for. Guess my PC will have to get a new PSU from another company to be ready for my event next weekend. Now, I have been on hold for over 30 minutes, waiting to talk to a Corsair Support rep via phone to escalate my 2nd replacement. Hopefully this one takes less than 2 months to get to me, and actually works once it does finally arrive.

Hey everyone, figured I'd post this warning here. I would highly recommend you NOT buy Corsair products off of Amazon! It all first started when I ordered a Corsair PSU off of Amazon. The first one I got was clearly not new and had been previously used (factory tape on external and internal boxes cut, resealed with shipping tape). Furthermore, the PSU was missing some parts (screws, etc). I shipped that PSU back, telling Amazon it was not a new unit, and Amazon sent me a replacement PSU, which was also not new (again, factory tape cut, but this one seemed to have all the parts). I still sent it back and got a refund, as I did not pay full price to get a refurbished or used unit. I thought it might just be the Corsair PSUs, but today, I received my new H150i Pro that I ordered from Amazon, and it too is clearly used! It is missing the thermal paste on the CPU part, and there is plenty of dust and scratches around the screw holes (especially on the CPU part) that show it was not only installed in someone's PC, but also USED for an extended period! Somehow, Amazon's warehouse of stock has been contaminated, or they are shipping referbished units when people are paying full price and should be getting new units. As such, I HIGHLY recommend NOT buying any corsair products from Amazon, and if you do, thoroughly inspect the product to make sure it is exactly what you ordered (new, not used, all parts are present, etc).

It was my understanding from others that Corsair replaces RMA equipment with refurbished equipment, not new. If that is not correct, then my appologies. I'm just basing off of what others have told me. As for returning to the retailer, I can't do that any more, as it is outside their return window. I am still waiting to hear from support on the RMA. It has been about a week now since I submitted my ticket though, and now that the system is in the process of being upgraded, I am unsure when to expect the replacement. I don't see how this can cause a power supply to straight up fail. Plus, the case is a Corsair case, which has a dedicated air intake for the PSU. Most of the time, the PSU was cool enough it didn't even need the fan, but I do know the fan worked as when gaming it did turn on. Plus, now that I have taken the PSU out of the case in preparation for the RMA attempt, I have been able to test it with the self test button. I hear a couple relays click, and the fan twitches once, then it just stops. The test LED does not light, and nothing else happens. So, it is definitely a bad PSU.

It finally died today. Nothing I do will get it to power on for more than half a second. Swapped it out with a spare PSU I have laying around, PC works fine. So, it is definitely the power supply. I'm just going to return the power supply and go with a different company. I don't want to RMA a less than 2 month old PSU I got for $400 to get a refurbished one back (referb units are like $250, and my PSU did not depreciate $150 in 2 months).

This just started happening to me yesterday after having this PC set up exactly the same for over a month now. The PC will randomly power down, then after a few seconds attempt to restart (fans start up, LEDs illuminate), but then immediately shut down again but only partially. It's almost like the 12V rail started, but then stopped within a second, but the 5V rail continues to run (2.5" HDDs keep spinning, but everything else stops). I have no fans, no lighting, nothing. The really odd part is the power button on my case will stay lit as if the computer is running, but it clearly isn't. The only way to clear this issue is to turn off the switch on the PSU, wait a few seconds for the capacitors to discharge and power off, then turn it back on. It does not need to fully boot into Windows for this to happen either. I had it on the BIOS monitor screen to watch temperatures and voltages to see if I could find what the issue was, and even in the BIOS it did it after a few minutes. All voltages and temperatures looked good too. I have so far found a way to keep the PC running though. If my PC does one of these faults and shuts down, but then successfully restarts without me needing to flip the switch, it will run seemingly fine as long as I want it to. But, if I have to flip the switch and restart it, it will fail within 30 minutes. Load tests on my PC show no temperature issues or voltage issues, even with me pushing almost 700W through the PSU (CPU and both GPUs at full load), so it doesn't seem to be a voltage sag issue. Probably going to open an RMA ticket with Corsair to swap the PSU out as at this point it seems to be the likely issue, especially since when it tries to restart my motherboard leaves the power LED lit even though there is no 12v rail. Plus, if I can make the PC reboot successfully after one of the failures it stays perfectly stable also seems to point more at the PSU than any other component. Just wanted to post all that so if others are seeing similar issues, they can comment. I saw that people report similar issues in the AX860i, but not knowing exactly how similar these PSUs are (besides wattage, obviously), I didn't want to post a AX1200i issue in that thread.
