Fan control

fantastic ... I have a pair of Sharkoons attached to my H50 and was running them directly from my PSU. Now I can connect them straight up to the mobo for auto control ... unless somebody can see a problem with that ???
 
As the sharkoons are 3 pin fans, im afraid the akasa pwm splitter cable wont be any use, theyll still run at full speed, as basically theyd still be getting power from the psu, and not having a pwm pin means that they cant receive a signal from the mobo cpu fan header to speed control them.

You can use the product in first link I provided above but whether you will be able to control it or not depends on your motherboard and the software you use. I use speedfan which works dropping my Noctua fans to 600rpm.
 
Ummmm i was using the auto fan control in the bios? Can the fan speed be altered automatically from the power case fan power supply on the mobo then?
 
That depends on your motherboard. Mine only allows control on CPU fan header and nothing else.

You also need to make sure that both fans are controlled at the same speed. It would be bad if one fan were spinning at say 1000rpm and the other at 700rpm, that's why they have these adapters.
 
I have the gigabyte ex58 ud5 mobo but i've adapted the two sharkoon fans to operate with the H50 water loop. At the moment the fans are running straight from the psu with their 4 pin adapters but I can also run withthe three pin plug as well ... it would be nice to let the fans idle down when not needed though
 
Same mobo as me so the only controllable fan header is the CPU fan header.

Set CPU fan control to Auto in BIOS, attach the two fans to the 3 pin splitter (non pwm one) and use speedfan to drop the speed below a threshold temperature. I have mine set to 100% at 60 degrees and 60% below. My fan speed only now ramps up speed with a demanding game or application.

I made my own splitter out of spare molex to fan splitters I had in my spares box.
