About case fan sensor assignment..

[MarleysBeard]

Working on a fan curve and a little confused about which sensors to assign to which fans.

I have 2 front intake fans, 1 rear exhaust and 1 top exhaust. I have the cooler master 212 on the CPU.

My current setup I have the 212 and the rear exhaust running off the CPU sensor. The other 3 fans are connected to a controller and that is running off the VRM MOS sensor. All my temps are fine but I noticed in HWiNFO that the VRM temp doesn't move much from min-max, none of the sensors do other than CPU and GPU. Although I don't see an option for System 1 and System 2 temps in HWiNFO so I've no idea what those are doing.

So question is do I keep the controller fan (top exhaust, front intakes) on the VRM MOS sensor? If not then which sensor should I run them off? Also how can I see the temps of the System 1 and 2 sensors? They show up in BIOS but I don't know how to see them within HWiNFO.

Thanks

 

Side question that's related to cooling, I have an old Corsair Carbide 300R. The cutouts for the two side panel 120mm fans aren't being used and I'm wondering if I could cover those with something? I'm sure it lets dust in and it certainly makes things more audible. How much would covering them affect cooling?

Get some dust filters, they sell magnetic ones if you are concerned about dust. Otherwise set your top fans to cpu temp and front to GPU or leave on the VRAM MOS sensor. If you had fans in the side panel set them to GPU, depending on the cooler style your GPU has.

Motherboard doesn't offer GPU Sensor as an option so I can't do that.

 

I've considered the magnetic dust filters but I'm also wondering about putting something that would block noise? The opening on the side is big enough it lets a lot of sound thru. I know lots of cases don't have vents on the sides so I was considering a bit of sound dampening material or something..

I doubt it would be an airflow issue but it shouldn't be much sound unless you are ramping up for gaming etc. Where does your tower sit in relation to you? moving it or external sound dampening might be a solution

The tower sits directly to my right but at an angle so the front is facing me. The fans in the front have RGB so I have it that way so I can see them. That also points the open side towards the monitor/back wall a bit to help me not hear it as much. It isn't crazy loud but I wouldn't mind it being a bit quieter. I'd put it on the floor but I have carpet and a heat vent that's very close to my desk.

Put some sound foam on the wall temporarily  (or something similar) where the sound is bouncing from to see if it helps. Look into a platform for your rig on the ground or a new space. I once made a rig stand from some old tile and some 2x4's

Set intakes at constant speed, something you are comfortable with. If noise is bothering you, use CPU temp with more aggressive curve than what you would for exhaust fans. Exhaust should use CPU sensor with curve that reflects best CPUs heating during gaming load and stress testing.

How would I go about this with 3 fans on one controller? I have to set them identical, they are also proprietary so I cant bypass the controller. I could switch the top exhaust to an intake, either on top or on the side panel. I would like to avoid putting a fan on the side panel tho as it would make removing it awkward.

 

Assuming I made the top an intake would the heat simply blow out the back exhaust and side panel? Its extremely open on the side. Maybe that would even help push dust out? This would make it 3 intakes 1 exhaust..

If you are limited to single controller chip, you really are out of options. Setup them bit more aggressive than what you maybe would like for noise reasons. CPU isn't getting as hot as GPU, or rather GPU can be at 75-80C while CPU is just at 60C.
