Looking to add a couple of extra fans but do not have the necessary spare connectors on my mobo. So whats the best way to add the extra connectors needed? I feel I should be Googling this, but I prefer the experienced voice's I get here. Links to where I can get what I need in the UK please. Thanks folks.
OOps, I found this which looks like it will do the job.http://www.ebuyer.com/product/225016?utm_source=google&utm_medium=products or this http://www.scan.co.uk/products/zalm...Power+Connector+(x1+Molex+powers+x4+upto+fans) Sorry folks.
That looks right. Your fans run off +12v and that's also the voltage of the molex plugs that these adapters are using. Just bear in mind that 12v will keep them at full throttle. The Zalman has +5v connectors you can choose that will slow (and quieten) the fans if you want that.
You can also get Y adapters so that you can attach 2 fans to one header on the motherboard, then the fans will be temperature controlled and not running at a constant speed.
Not all motherboard headers are rated to handle the current involved in running more than one fan so the general advice is to be careful using y-adapters/splitters with mobo fan headers. I run five 120mm fans off one header in my system, but the headers on my board (Gigabyte X58 UD5) are rated for up to 2W, according to their support rep that I spoke to. It's best to check in advance how much current the headers can handle before daisy-chaining fans.
i find 5v to be too slow for my personal liking. i tend to run most fans (if they arent going through a fan controller) at 7V. its easy to modify the standard molex fan adapter by moving the black (-) fan wire to correspond with the red wire on your PSU molex plug.
