Ran out of space for fans on MB. Connect them to PSU?

I have this PSU:

http://www.amazon.co.uk/Corsair-Builder-Series-Bronze-Supply/dp/B009RMP44O/ref=sr_1_1?ie=UTF8&qid=1373479485&sr=8-1&keywords=corsair+600w

And I wish to have another 3 fans in my case since it only came with one and now it's summer it's overheating. However there is no space left on my motherboard for more fans. If someone could give me an example of a 60mm fan and how to connect it I would be deeply grateful :)

  1. Your PSU comes with "molex" connections. Most fans connect this way. Just know that whichever fans you connect to the PSU will run at 100% all the time. I would recommend putting any exhaust fans on the PSU and let them run 100%. That's if you want to use a fan controller for some, it works best to keep the exhaust off the controller and let them run 100%.

    Hello,

    There are a couple options in the situation. Depending on the number of fans you need to add typically a Y fan splitter like this http://www.newegg.com/Product/Product.aspx?Item=N82E16812200855 is a viable solution. That should also allow the fan speed to be controlled by the motherboard. Connecting the fans via molex adapters to the PSU will work, however the downside is that those fans will always spin at 100% which can get quite noisy.

    Hope that helps

  3. You could always get a fan controller, i bought this one and I'm liking it.

    Well I don't have space on my motherboard so only 1 fan can be connected to it. So the other 3 wherever they are will have to run at 100%

This is an example of a 60mm fan. http://www.newegg.com/Product/Product.aspx?Item=N82E16835426033 It depends greatly on how many RPM you want that bad boy to run at. If you don't need a ton of cooling, you can get by with a lower RPM. I, personally, like to get as much RPM as possible out of each fan because noise is not a factor for me.
