Speedfan doesn't see my case fan

[Muse]

MSIK8N Neo-FSR/ V V2.0 motherboard has fan1 and fan3 3-pin fan connectors, and I have my single solitary case fan (Vantec Stealth 80mm exhausting at the rear) plugged into fan1 with the 3-pin/3-wire connection that's stock with the fan. Speedfan shows 0 RPM for the fan, but I know it's running... I can stick my finger into the blades and it's the loudest thing in my system. Any clue what I can do to get Speedfan (or something else) to see the fan and regulate its speed?

With my former PSU (Antec True430), the fan was automatically run at a slow speed unless the PSU sensed high temperatures. My new Corsair 520HX doesn't feature that, so I have the fan plugged into the motherboard hoping to be able to monitor and control it.

Speedfan is generic - you have to see what your BIOS is reading and then configure SF to match. Use the utility that came with your mobo if you want it to work properly without the fuss.

Well, a mod at MSI Forums told me to ditch MSI's Core Center and use Speed Fan and/or a host of other utilities:

better avoid MSI utilities and use alternatives like:
Speedfan,CoreTemp,CoreMeter,NextSensor,RivaTuner, Clockgen.

He suggested I swap out the fan and see if that resolves the problem. Said doing so fixed a similar problem for him.

The BIOS doesn't show anything for the case fans. I searched very thoroughly today and found nothing. The only fans the BIOS has any information on or configuration for are the CPU and the NB fans, and they didn't supply a NB fan with my motherboard, so I'm not using one. I suppose it might be an option to plug that case fan into the header for the NB fan.

The Bios should show the current mobo health values somewhere - voltages, temps and fan rpms. My non-MSI mobo shows the the current readings in a BIOS page and it's a lot older than yours.

And you're assuming that the mods at the MSI forums actually know something.. They often get the position just because they are willing to do it - not because they are any tech wiz. I always use the mfr's utility first and if it doesn't do it for me, I'll try something else. And on some like the Abit mobos with the uGuru chip you really can't use any of the generic utilities.

Thanks. The MSI Phoenix/Award BIOS has a PC-health menu and under that you can see various things inclucing CPU and NB fan speeds. No other fans are presented. It also shoes CPU and NB temperatures. There are no configuration options in that menu, it's simply to monitor values. I combed the BIOS for something pertaining to the other fans, meaning those two fan connectors on the MB, but found nothing (yesterday). You may be perfectly right about those MSI Forums mods. Presumably, it's strictly volunteer and I should try the MSI utilities and see what my experience is and not just take one guy's word for it. I did try Core Center, and found it not very useful except that it apparently does allow me to try OC settings without having to reboot. That's nice! Other than that, it doesn't do much, AFAIK.

I should comb through the threads at MSI Forums and see what people use and talk about. There's time. I have a couple of resistors I can use to slow down that fan (one or the other resistor), or I can try connecting the fan to the PSU, flipping over the Molex and getting 5 volts to it. Meantime, I've become used to the fan, but I know it's louder than what I was used to with my other PSU.

Maybe those other fans can't be seen for some reason then. Do you know for sure that the speed sensor function on them is working? I know some sharps out there sell the non-sensor panaflos with a three wire pigtail, but the fan itself lacks the speed sensor - tricky, eh?.. I use a fan controller that handles controlling and reading the fan speeds too (digital display) and reads four temps as well. I only use the mobo connectors as a last resort. Some of my fans can draw more current than many mobos can supply anyway.

I just checked out all my 80mm fans and only the Vantec Stealth has 3 wires. I have a handful of Panaflos with 2 wires. I don't know that the Vantec Stealth supports the sensor, but why else would they have a 3rd wire? I have another, so I can swap them and hope for a different result.

I may wind up getting a fan control module such as you have. I've priced them in the past. Short term, I'll see if I like a simpler, cheaper solution. I bought a couple of large resistors just for this purpose I haven't tried yet. Think I'll give them a whirl to slow down that fan.
