noctura

I bought 2 140mm noctura case fans last year (not sure on name, they are grey) and one of them works fine but the other will wiggle around and not spin until you actually manualy make it spin ( with my hand). Is this a hardware issue? Just making sure before I buy new fans. Thanks

Hey guys , possibly stupid question but we’re would you put your best case fan ??? I have a phanteks enthoo pro TG with two 144mm fans up front sucking air in and another 144m on the back sucking air out. Then I have an kraken x62 aio liquid cooler radiator on steam top exhausting air as well...
