Do I need 3pin fans instead of PWM?? HELP

Recommended Posts

Posted · Original PosterOP

So I swapped in some Noctua industrial fans into a Supermicro case while back and I got the PWM 3000rpm model since the motherboard uses PWM through IPMI to control fan speed. The threshold is like 800rpm or something before a low fan speed warning comes on, theres three fan speed settings (Standard, Optimal, Full) and unless the mode is set to full the Noctua fans will not get above 600rpm. Do I need to buy 3pin fans instead?? Would they run at full speed then?

Here is what Noctua a page on industrial fans says. “

My fan doesn’t spin when I start up the PC - is it faulty? 

If you've connected the fan directly (or using the supplied Low-Noise or Ultra-Low-Noise-Adaptors) to your mainboard, it's possible that the mainboard's automatic fan controller doesn't provide the required starting voltage due to the low CPU temperature. Please verify whether the fan starts spinning at higher CPU temperatures, remove any Low-Noise or Ultra-Low-Noise Adaptors, deactivate your mainboard's automatic fan controller in the BIOS or connect the fan directly to the power supply using the supplied 3:4-pin adaptor.”

This.

 

Check your iPPC fans, there are 2 models of iPPC fans. the one which has 12v and 24v spec.

Which one is yours? If you have the 24v models you wont get its max speed ever, as your motherboard only outputting 12v max so it's half the max speed.

Its a Supermicro server motherboard (SUPERMICRO X9SRL-F) and I purchased the 12v model fans.

Fan speed will change and they will max out at 3000rpm the problem seems to be that they curve at a way lower rate than the other fans.

I bought the 12v fans, maybe I need the 24v fans?? I will link the supermicro exhaust fans I have below.

This is what supermicro's website says, I know that this is the problem. I want to know if I can solve the problem by using a non-PWM fan? Would a 3-pin fan run at a higher speed since its not PWM??

general FAQs (Fans)

I'm experiencing fan speed issues with my motherboard from Supermicro, what can I do?

 

The BIOS of many motherboard models from Supermicro expects a certain minimum fan speed (usually 600 or 700rpm), which is higher than the minimum fan speed that can be achieved with Noctua's PWM fan models. The BIOS may interpret the low minimum RPM of Noctua fans as a fan error and thus try to run the fan at 100% for a short period before going back to automatic control. This can result in oscillating fan speeds and fan speed warnings in the BIOS or the fan management console.

Unfortunately there is usually no option to set a lower minimum value in the BIOS that would suit the low minimum speed of Noctua PWM fans. The issue can thus only be resolved by either disabling automatic fan speed control in BIOS, which will cause the fans to run at a constant speed, by using 3rd party tools like IPMItool or IPMIutil, or by requesting a modified BIOS file from Supermicro, which takes the minimum fan speed of Noctua fans into account (charges might apply). Please note that any modifications performed with 3rd party tools are done at your own risk and that Noctua can not be held responsible for any possible issues.

No, 3pin fans would run at 100% rpm as mentioned in the motherboard manual.

It seems like you can use Noctua's NA-FC1 fan controller as an offset to the motherboard's signal if you want a hardware solution: https://forums.servethehome.com/index.php?threads/supermicro-x9-x10-x11-fan-speed-control.10059/page-2#post-228570

Have you tried changing the fan thresholds? https://www.ixsystems.com/community/threads/thermal-and-accoustical-design-validation.28364/post-214105
