Questions regarding under volting fans

Melt My GPU

Hey guys and gals of LTT forums,

 

I currently own an enthoo primo and have added even more fans for my loop so in total I have 9 fans running in this thing. Individually they're very quiet but when you have 9 of them not so much. It's not an annoying 'motor wine' sound or anything (thank goodness) and it's pretty much just the 'whooshing' of air. However whilst I don't mind the noise myself I'm trying to be a bit more discrete when using my computer as I get up before anyone else in my household and I'm certain they're being woken or at least half woken when I hit that power button.

 

I have 8 of the fans running off of the fan hub the enthoo which connects to the CPU fan header and 1 of them running of the motherboard which I know from the manual says the speed cannot be adjusted (full 12v at all times). This I don't mind as like I said individually they're very quiet as long as I can tone down the other 8.

 

I don't want to do it via 'hardware' (inline resisters etc) as I don't want to take apart what is literally the nightmare of all cabling on the back (never get a non modular power supply with all those stock I/O cables omg) and I doubt my motherboard has anything like that Asus fan control that comes with their boards, so I was wondering what software is there that I can use.

 

One of my concerns is I don't want to damage the motors of the fans by running them at a voltage they weren't rated for or end up producing other weird noises, is this an actual issue with under-volting or?

 

Finally here are the fans I have in my case: Here (the ones the case comes with) and here (the ones I brought)

 

TL;DR: I'm trying to make my PC quieter through under-volting but I was wondering if it's safe for the motors and what's the best/easiest way to do it though software?

Undervolting is fine. It won't harm the motors, in fact it will probably lengthen its lifespan. Just don't overvolt.

You can do it with the fan control settings on your motherboard, its perfectly safe

I don't remember the last time I heard of under-volting something hurting it, so you should be just fine.

Oh well that's a relief, I think the last thing I would plan to do is over volt :P Thanks for the help

Last time I checked on my motherboard there wasn't any extensive options if memory serves me right but I'll be sure to check again. For reference my motherboard is an Asrock Z77 Extreme 6.
