Hmm... that is odd. I cooled a 70w HPS cabinet for years using only 2 12v computer fans. The must be something wrong. Mismatched voltage, or maybe your adapter is running short in the milliamp department (maybe it is a cellphone charger or a trickle charger). Or maybe you were expecting hurricane for winds out of a couple small fans? Try a different adapter.
Skeebo Reviewed by Skeebo on . Blah computer fans Well i went and bought an adapter and i'm very disapointed. When i hook up two pc fans and turn it to 12 volts it barely moves any air... I don't see how you guys hook up 6 fans to a single adapter. Rating: 5
