Lower the RPM on Scythe Gentle Typhoon 1850 RPM through using the motherboard?

post #1 of 4
Thread Starter 
Hi, I just got my Gentle Typhoons in my case, and I can't seem to lower the RPM of the fans through AI Suite. In the fan test, the resoults are that the fan run on the same RPM (around 1800) on all the percantages.

After googling a little, I found that this was a normal problem, but I couldn't really find a fix, and since these fans are so popular, there got to be one!

So, anyone know how I can lower the RPM on my GTs without using a fan controller other than the one on my mobo?

Someone may correct me but I've found when 3 pin fans (non pwm) are plugged in to the 4 pin (pwm) CPU headers then they will not automatically vary through any software. Only 4 pin (pwm) fans will work there.

I got round this by using the 3 pin chassis headers for my CPU fans instead. You can then use one of the pre defined profiles under the chassis fan heading in AI suite or create a custom one. Bare in mind though that you will need at least one fan plugged in to the CPU header or the PC will not boot as it thinks that there is no cooling connected for the CPU. I'm sure there is probably a way of disabling this in the BIOS but I haven't bothered to find it as I have my front fan on my HAF 932 plugged in to it which is quiet any way and does not need to be controlled for any reason.

Depending on the mobo (you don't have your rig sig filled out) some have the option for either PWM or DC Fan in the bios. Might be worth looking through your manual for a quick check!

I too put off going with a fan controller but now after what I've learned by running this http://www.newegg.com/Product/Product.aspx?Item=N82E16811995075 I am so sorry I waited so long. This controller does allow the AP-15 to be used as a PWM fan.
