CPU fan not spinning

[MrAlbertrocks]

So I've had my PC with an AIO h80i GT cooler for a year now, and i haven't encountered a single issue until today. Since the first boot for my PC, a program called AI Suite 3 has been running in the background at all times, it was recommended by Asus so i figured it was best just to leave it be. My cooler worked perfectly until today, when i decided to close the program. I looked into my PC (glass panel) and saw that the CPU fan wasn't working, don't know about the pump. I figured it was just a fan profile that the program had set, so i thought when the CPU reaches a high temp, the fan will start spinning again. I launched Witcher 3, and just 10 seconds in i saw my CPU temp go from 60 to 80, the fan never started, i closed the game immediately. I reopened the program and went to Fanxpert or something like that and clicked "Standard profile". Looks like the fan is back to normality, but it is extremely unsettling that my CPU fan only works when a certain program is open. 

 

Please, i would appreciate if someone sheds some light into this issue.

Note that my normal temps were 25-30 at idle, 35-45c at load before the issue. When i closed AI Suite 3 for the first time, my cpu started idling at 60c. Something is clearly wrong here.

AI Suite will be controlling your fans, closing it meant nothing was controlling it so turned it off completely. 

 

Also sounds like it's controlling the pump, would explain the instant high temps

So it is an obligation to have that program running at all times? What about people that don't even have that program installed? And why does my PC even let me do that if it means my CPU will just fry.

Can set fan speeds through bios, or other programs like speedfan. 

 

You don't have to have it running, but unless you want to go onto bios and set the fans yourself, or in another program for that matter, it's easier to just leave it.

Umm. Just from past experience there might be a conflict. Corsair does not like AI Suite. They do not play well together.

 

Usually how the Corsair AIO's work is a locked rpm on the pump (in my case it reported as 2000, or 3000 rpm depending on the profile). And the fans were variable depending on the fan curve I assigned those fans. Please note I did have the fans tied to the pump directly, and the pump was my "cpu fan"

 

If no fan controller software is used then the fan speeds in this case default to whatever corsair feels like supplying.

Please note my experience is with h100i, and h110i GT's. I haven't used the single 120mm rad solution.

Well, the problem is solved as long as AI Suite is active, but i find it strange that the fans will simply stay idle even though the CPU is getting dangerously hot. That should not happen, ever, even if there's no software controlling it. That's why i wanted people to shed some light, i already solved the issue, but i would like to know WHY does the CPU fan stays idle even though the CPU is extremely hot. There should be a default profile, but IDK.

Yea that is pretty weird there should be a default fan profile in your bios that should have taken over when you closed AI Suite, I'm guessing its a conflict with Corsair and Asus' software.

Mine have always ran on every asus board I've ever had. Even with the software off. Is the fan not plugged into the CPU header?

[Mira Yurizaki]

If I recall correctly with a Corsair AIO, the fans don't even go into the motherboard header. They go into the unit itself. What goes into the motherboard header is what the pump is running at or some other dummy value to keep the system happy and think there's a working fan.

 

I would uninstall AI Suite first to see if the problem goes away. The software is not required for normal operation.

Think that depends on the model, my H55 for example, the fan and pump plug into motherboard headers.

[Mick Naughty]

The i series have the option to plug into the pump. Then using the USB dongle for the link software. But without any info from the op all we can do is assume.

I find this problem intriguing. Sorry you experience it. I bought a "cheap case" which has individual fan controls you can set manually. I like this more, I just plugged my fans into their switches and use that to turn the fan speeds higher or lower. The only fans that are actively controlled are the cpu fan and the power supply.

I think i may have found the problem. I was running AI Suite 3 and Corsair Link and the same time and they were causing the issue. I've heard that Asus doesn't work well with Corsair, i closed both programs and disabled them at startup, did a full restart and the fan were working properly. I don't know if it was a glitch between both software that was interfering with the default profile in the bios kicking in, but i'm glad it's over. Thanks for the advice .

I wanna preserve this post in order to show that indeed, your software configuration can be causing issues :3

 

But good to know you've solved it.

Yes this is a known issue with Asetek/Corsair AIOs. Other known issues are AIDA64, HWInfo/monitor, and a few others. You can't have any other software monitoring the AIO sensors. There's more info in my signature and on Corsair's forums.
