P.S I don't have to use 3pin to 2x3pin for every of 3 connectors? I can use for example 3pin to 4x3pin just for one connector and it will work anyway? Availability of 3pin to 2x3pin adapters is pretty horrible, 10 days of waiting for them.

You should be able to use three or four pin splitters just fine. The third and fourth pins won't be used for this fan controller anyway. It just changes the voltage, there's no provision for rpm reading or PWM. Also, I wouldn't use more than six fans. Daisy chaining splitters isn't the best of ideas.

Agree with this above.

Does your motherboard has extra fan headers?

In my R5, the two front intakes run at 5V off using the R5 case harness powered by a SATA power connector.

Rear exhaust and bottom fan use MoBo fan headers controlled by speedfan

Rear exhaust always runs, but slowly and ramps up with CPU temp. Fan curve matches the CPU cooler fan curve.

Bottom intake turns off when CPU cores are less than 40C or GPU less than 45C. ( which is most of the time unless gaming or encoding, or running multiple VMs). The speed of the bottom intake is controlled by a combination of GPU or CPU temps, but the GPU temps are what cause it to spin up.

Side fan is removed for now. Since it is summer that may change, but it will be powered by the temp of the graphics card.

I can barely hear the system at idle, and the loudest thing are the two HDDs.

I can barely hear the system at idle, and the loudest thing are the two HDDs.

I have 4 or even 5 motherborad fan headers, but motherboard is the weakest point of my system, it is Asus Z97-P. Software is horribly bad plus SpeedFan cannot even read temperatures properly from it. I tried to set it up with guide but nothing seems to work on my mobo from this accursed manufacturer. I bought this mobo when I wasn't too much into tech, and this is how it ends - very short in features, overpriced, with horrible AI Suite software and inability to set up any third party software. But I wanted gold color on my motherboard... Ehh, I was so stupid back then biggrin.gif

I am pretty much satisfied with noise levels at the moment. Even with side moduvent removed it is okay, audible only in total silence, and I am always listening to music, review, interview or playing games when I am using PC, so I won't hear it anyway. I also have my windows open almost all the time so ambient noise in increasing quite significantly. I don't plan to increase fan speeds to 7 or let alone 12V. The whole point of my system is total silence and don't burn anything biggrin.gif It was quite hard to achieve with 980 Ti that is super hot after OC, but now I will temporarily get RX480 if it turns out to be good so I will keep those very low noise levels even under load. And when Vega comes I don't know, I hope for some beefy coolers like those third party ones from Arctic.

I will order additional fan for the side panel and 140mm magnetic dust filter and I will test how it works for me, so far removing side panel moduvent didn't made much of a difference.

One thing I would like to change is to make fan controller Off-5V-7V instead of 5V-7V-12V. Is it possible? I will make separate thread with this question.

I want to control at least 4 fans, or better 5.

I want the to work only on 5V, if it is important. 
I bet the R5 "controller" is the same as R4 and is nothing more than gorram switch that connects all the fans you connect to it to a PSU on either 0-12V, 0-5V or 5-12V, giving you 12,5,7V options of speed for the fans. As long at the switch or it's PCB doesn't burn you're fine. Sure don't connect 20 delta fans to it that draw 20A right, but say up to 2A you should be fine for what the switch can handle. I use crappy Chinese switches in other things even at 5A no problem.

Oh yeah, R5 still has the 3 speed R4 controller, I'm sure.

Thanks for answer. Can I somehow make this controller work on Off-5V-7V instead of 5V-7V-12V?

Mmm, technically might be possible, but you would need to make your own PCB but maybe not even that, just rewire how the input cable the SATA power on R5 and molex power on R4 connects to the PCB.




This is my controller on R4. It may be possible depending on how the switch connects the traces, best would really be a custom PCB.

Personally I find this switch useless as any motherboard has superior fan controlling capability with fan speed, PWM, etc. and controls the fans based on temperatures. They could just remove this useless switch IMHO and save me the $5 in price. It's a gimmick no one should be using really.

On the other hand it could be used to dim LED lights or other gimmicks like that. But all in all these simple devices also cost a couple $ on ebay if you need them.

Question about the Define S.

The front panel on my case seems to resonate, like it's amplifying the vibrations from my platter HDD. It quiets down considerably if I touch the front panel with my hand.
Is this normal?

I am considering applying some sound deadening mats (butyl / bitumen) to the panel to lower it's resonant frequency, but if this isn't normal and my case is faulty I'll just send it back before performing mods like this.

I found this post:

Also if I take off the dust filter panel it stops which is contrary to your experience.

Which is for the R4 which I believe does have some sound deadening applied to the front panel already.
Also, in the silentpcreview article the reviewer mentions the HDD mounts are rather ineffective at reducing vibrations.

The vibrations from my HDD are very noticable at idle. I made the mistake of putting my windows "Users" folder on this particular drive to save SSD space so it's pretty much always running as well.
I have googled this issue a bit and some users (forum posts) claim you should't tighten the screws that attach the HDD too much as it reduces the vibration damping of the rubber mounts, which does make some sense so I'm gonna try that and see if it helps (I tightened them hard which may be an issue).

So I'm guessing what I'm experiencing is normal and not a fault with the case, but I would like some input on this.
post #14349 of 16136
All cases have some parts that fit in ways that can resonate at certain frequencies. My 5.25" bay would "sing" when I would tap on it because it wasn't dampened, hell even after putting some STP silver on it it still did because of it's connection to the case. Stuffed it with open cell foam and it's quiet.

R5/4 has the front panel filled with some material and open cell foam. Sure adding sound dampening that increases it's weight will shift the frequencies and reduce resonance.

I don't think resonance counts as defective, it would have to be unattached or something.

Yes HDD mounts even with the rubber pads are useless IMHO, you would need sorbothane mounts which is a material quite expensive and is used for audio equipment feet, helicopter camera mounts, as a mod in airsoft guns, mods for shoes, ... you can find videos of people hitting their hand with a hammer where there is sorbothane over their hand, it distributes and dampens very well. I have not seen sorbothane used in PC at all.

It's not a fault of your particular case certainly not one for a valid RMA.

You can search my posts here with STP silver added to R4 and HDD mounted with a rubber cord in several positions in R4. Not that my HDD needs it but considering I don't like any cages in a case because all they do is vibrate and block airflow I mounted my HDD floating with rubber cord. It's sort of like paracord with the inside being rubber strands and it stretches just like a rubber band does.

My avatar shows the HDD floating in air in R4.

You could make similar HDD mount in Define S, or strap it with rubber band on a open cell foam padding. You have to be creative.

Thanks for your post JackCY! I still think it's strange that a "silent" case from a popular manufacturer would do this by design, but the quality of the front panel plastic combined with the HDD mounted to the MB backplate makes it very likely.

Anyway my plan is to apply some deadening to the front panel and move my "Users" partition to an SSD. The remaining HDD space is just used for rarely-accessed storage, but if the drive noise still bothers me I'll figure out a better way to mount the drive.
