Hi i recently bought some cooling fans with a 4 pin molex connection , i also bought 4 pin molex ac/dc adapter , to power the ac adapter i am using my desktop power cable . Now the light on the adapter turns green but when i connect the fan to the adapter there is no motion . The strange thing is when i first connected the fan to the adapter it worked , but now nothing happens ? what could be the problem ? here are the links to the items i bought to give you a better description of them :- 4 Pin Cooling Fan Cooler for Desktop PC Case 120x120mm on eBay (end time 02-Apr-10 11:00:30 BST) 12V+5V AC Adapter Power Supply HDD HARD DISK DRIVE IDE on eBay (end time 13-Apr-10 09:00:26 BST)
