Can somebody please advise me on this
I have a power adaptor output 12V dc,300mA,will a cooling fan with a power rating of 12V and 0.60A work on this adaptor and is it possible to connect two of these fans to this adaptor?
Thankyou in advance

0.60A equals 600mA. So no, it's too hungry for that adaptor. But the good news is that you can find a 1A (1,000 mA) adaptor pretty easily and cheaply these days. Look for a light one, without a heavy transformer like the old kind. It'll be more efficient. For two fans at 600mA each, look for an adaptor rated to 1.5A or more.

No the power rating of the fan is 12V and 0.60A, now the problem is you have a source of 12V 300mA or 0.3 Amp and for the fan you need 0.6A or 600mA (0.6 * 1000),not a single one will run properly with your adaptor.

BTW, are you sure the fan is rated at 0.60A and not 0.060A (60mA)? 600mA would be a whopping cooling fan, and I have a bunch of 60mA fans.
