Psu fan control?

Hello friends, so I just recently got fed up the temps in the computer and decided to buy 4 af120's. They are connected to the psu directly. It is an evga supernova 750B2 psu. The fans are connected directly via 3 pin to molex adapters, some bitfenix alchemy's I believe. The fans are at full blast and the noise is unbearable. It sounds like an industrial fan and the mic picks it up so I have a hard time chatting with friends on skype. Is there any way to adjust fan speeds via the psu, or will I have to purchase a fan controller?

i am pretty sure you need a fan controller, unless you have software that controls the psu.  you can use y connectors to attach two fans per motherboard header. i say that since they are the same fans. they should have somewhat equivalent rpms. but a fan controller is cool and some come with even more pretty lights. i am huge fan of the red af120/140 and have 2 140s and 3 120s in my arc mini. i use the fan controller for the intakes and the motherboard headers for the egress fans. 

You could perhaps buy a low voltage adapter; it's probably not possible through software due to the fact you're using a three pin connection and as an alternate to a fan controller, you could look into buying quieter fans.

Any fan controller recommendations?

im taking a look @ this atm

As william mentioned, a low voltage adapter is most likely the cheapest rout.  Are you from Canada if you don't mind me asking?  Amazon isn't typically the best place to go with their high Canadian prices :(

yeah, I live in Alberta. A store next to me memoryexpress sells one for 24.99
