I'd like to make my ram coolers run slower.
these are connected to a power fan socket.
this socket is placed right next to the ram sockets so thought that this was the right fan connector to connect my fan with. might not be . if this is not the right place then please tell me. it's running at 5600rpm and find it pretty high to be normal.
is there a way to undervoltage them to solve this problem?
 
Solution
IF the fan is 3 pin, regardless of what fan header you plug it into it will run at a constant voltage. A fan controler which is a physical device that fits into a 5.25" bay and allows you to control the voltage to a 3 Pin voltage controlled fan. I normally recommend NZXT's lineup.

If by socket, you mean the 3/4 pin fan (most likely) header on the motherboard then you're fine, unless its molex powered or something. Is the ram cooler 4 pin PWM or 3 Pin? If its 4 Pin you should be able to configure it in the bios provided the header you have it plugged into is 4 pin. If your fan is 3 pin voltage controlled, your only option would be getting a fan controller. I undervolt my case fans unless I'm gaming.

yes i mean the 3/4pin fan, in this case it's a 3 pin fan. so like you said my best option is to get a fan controller. with fan controller you mean some kind of program or is this a switch i add? i'm not talking about case fans, just in case you missunderstood.

ps. if my fan has 3 small built-in fans would this also mean that the rpm ratio shown is the tripled rpm of one fan? or should i just connect it with a system fan 3pin instead of the powerfan 3pin?

my system fans are powered by molex.

I read that it's completely normal that ram fans run at a seeming to high speed.
this is so because the fans are small and need to run faster to produce enough airflow.
It's hard to believe that a powerfan header runs on the same constant voltage as a cpu fan header.
I read that the power fan header takes it's power directly from the power supply, wich means it gets 12V.
