Hi.
I have my two case fans connected directly to my motherboard sysfan connectors. Both are only 3pin (non-PWM), connected to 3pin connectors sysfan1 and sysfan2.
To prevent the fans running at full speed all the time, I figured how to control their speed. I can set them to static speed in BIOS (for example 50%), or dynamically control them from SpeedFan application - for example based on my PHC/chipset temperature the fans can run from 0% to 100%.
I wanted to have even more airflow in my case so I bought two new Noctua fans (also 3pin non-PWM) and connected them to two remaining motherboard fan connectors - sysfan3 and sysfan4. But I cannot control them same as those first two fans. It seems like my motherboard allows to control fans connected to sysfan 1-2, but not 3-4. I have an older MSI P67A-C45 (B3) and another thread in some forum confirms that.
So my question is, if use a "Y" shape fan splitter (two 3pin to one 3pin), how it will appear to BIOS or SpeedFan?
Let's say I will connect two front fans over the splitter to sysfan1 connector.
Will the system ignore the fact there are actually two fans connected to one port and let me configure the port like before?
For example if I set 50% on sysfan1 in BIOS, will both run at 50%?
In case of SpeedFan, where I can configure sysfan1 to increase speed based on chipset temperature. Will both fans dynamically change speed like one (mirroring)?
Or will the speed I set be divided by two, because there will be two fans connected to one motherboard connector?
Thank you.
