Testing fans

[TooNice]

Is there an easy way to test fans without the motherboard? I've received my P182 yesterday, and I am considering swapping the stock fans with Yate Loons I bought long time ago. I hear that YL vary in quality, and I'd like to compare them to stock case fans.

Oh yea, my YL are 'closed' - will that be a problem for the case? From my understanding some heatsinks, including the Thermalright Ultra 120 Extreme only works with 'open' fans. So I guess I'll have to look for another fan for the heatsink.

Depends on the fan connections.
if they are 3pin then you'll need some way to connect them to the psu. (normally a connector that goes onto a molunex)

You can then jump start the PSU with a paperclip

any fans connected to the psu will also start up

I've seen reviews use normal batteries to test fans. But you'd probably have to find the right volts/amps or it could break the fan.

I don't think you'll have any problems with open/closed fans when you are using them as case fans. But for the Thermalright U 123 E, it does need to be open. You might get away with a closed one, but its not ideal. Its basically just a big metal clip that you kind of bend around the heatsink and the fan, and it holds the fan onto the heatsink. When the fan has those closed corners, the metal clip thingy can't really get a good grip of the fan.

You can easily modify them though (evidently). You can just use a little saw, and cut out those little bits of plastic that make the fan a closed fan.

p.s. This shows what open and closed corners look like:

Thanks. They are 3 pins indeed. It looks like Hexus doesn't like the site you are linking to: I get a a bunch of stars .net.

Edit: Yea, I've seen the mods performed to closed fans - but I would rather stay away from any form of cutting, so I guess I'll be looking for an alternative fan. Does the same apply for the Ninja?

I just get 2 wires and use my old megadrive 12v dc adapter to spin them up
best to use the psu though, if it's those 3 pin mobo connectors then i got a converter to a 4 pin molex one which I use.

Nope. See the first pic in the following thread (edit: see a few pics below as well as that contains a closer pic)

Ninja in my computer is running fanless so I had to check the above site.

Edit: I believe the Ninja comes with a decent (read quiet) fan.

Oooo yes it does odd.
If I've broken any rule there I applogise didn't realise

EDIT: I actually use an old Qtec psu to test fans on not managed to over load it yet, even with a whole 4 120mm fans

Are you sure the heatsinks inside the psu haven't melted?
