Would these fans do the job (400W HPS).

Nope

You should use an air mover with a reating of several hundred cfm.

Try to locate a dayton or vortex blower.

Those only put out at most in the low 50 cfm at most. It may work in a small grow area for fresh air in but not an active exhause.

Sorry

Im planning on getting these and having one for active intake/blowing on plants and 1 for cooling the heat from the light. ---> http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=7617002059&sspagename=ADME%3AL%3ARTQ%3ACA%3A1&rd=1 Do you think theyed do the trick?
