Question Is it normal for case fans to keep spinning after suspension?

[NoofenNN]

Got a new pc recently and I noticed both of my case fans (wired up to MOBO) keep spinning after suspension. This doesn't seem to be the case with my old pc, where the only fan that is connected to the motherboard has no problem stopping it after i tell it to suspend. The CPU fan in my new one also has no problem stopping after suspension. Has anyone else had this issue before? How do you fix it? Thanks in advance.

I already asked this a while ago, but I responded a bit late and ultimately didn't get a solution unfortunately.

What's the case and fan models??

 

[NoofenNN]

The case is a Nox Hummer MC, the fans are the ones that came with it, looks to me like they are these ones: https://www.pccomponentes.com/nox-h-fan-hummer-pwm-120mm

Bizarre, have you considered plugging them to the case fan controller instead.

I actually prefer manual control when the case has a controller built in.

I know its not exactly 'solving' the issue but it kind of is.

I did have them plugged into the case fan controller when i had a different motherboard in here and that worked just fine, but i'd much rather not have to do that again, I like them plugged into the motherboard better.

What motherboard is it you're using? , also the case fans - do they just have a 3/4pin connector or a molex aswell?

 

[NoofenNN]

The MB is an Asus TUF B450M-Plus Gaming, the fans only have a 4pin each

 

[madmatt30]

So this is happening when you put the pc into 'sleep' mode??

Assuming if you shutdown properly the fans stop completely??

 

[NoofenNN]

Yup, that's correct, although I had to enable the ERP setting in the BIOS for shutdown to work correctly

 

[madmatt30]

Its a sleep state issue, seems to be running s1 rather than s3 which would be the norm.

DDon't believe these states are actual available on ryzen per se.

HHave you tried deep sleep enabled in bios, not exactly sure where it is in your bios but this tends to be disabled by default on ryzen chipsets

 

[NoofenNN]

Couldn't find it, is there any other way it's marked usually?

 

[madmatt30]

Open a command prompt and type

Powercfg - a

Will give you a list of available sleep states, it's possible to force s3 from within windows 10 if it's available.

 

[NoofenNN]

So it would seem like it's only S1, S2 and S0 that aren't available. How would one force S3?
