Effectiveness of whole room air circulators?

im running a 423 watt 4 foot 8 tube T5 system with some supplemental cfl 60 watt cfls. I just have a basic desk fan doesnt really keep too good control of the temps when im away because i cant just leave the AC on in the house all day it can get around 85-87, 92 if im unlucky on a hot day, A friend of mine wants to gift me a 400w HPS for starting some clones but off tops I already know I need a better ventilation system. I currently have cardboard taped over the window to prevent light leaks so I dont see how I could get an exhaust system worked in to my room but I was curious if anybody has any experience with on e of these whole room air circulators and their effectiveness, yes there are different sizes and wattage and what not im just wondering if anybody has much experience with this brand/style of air circulators, http://www.amazon.com/Vornado-733B-Full-size-Whole-Circulator/dp/B000MI3HJQ/ref=sr_1_2?s=home-garden&ie=UTF8&qid=1376875732&sr=1-2&keywords=whole+room+air+circulator pros cons tips would be helpful

ohhhh this is a fun one

ok buddy i am sorry to say but u need a window ac unit for that room (unless u are running CO2 enrichment those temps way to high ) so the THC of the strain u are growing has been reduced alot by the time u get it in the jars

here is a good one Remote temp read out timer engery star ..........this will solve the air flow humity and heat issuese

the only thing u need to worry about is the drip water it will have the weed smell ...........to counter this u have the drip water land in a planter of chillis or jasmine this will mess with the doggies noses but not hurt them

the whole air thing does work but not as effective as u think ..................think of the air like water in the bath tub u move it one way it goes but loses power with every deflection.......so to make it effect and to keep the room cool u need multi fans set at the right angles and a exhust for the hot air and intake of cool air

honestly the most ettect method would be a window shaker AC u can set it on for the hot part of the days to run ac and when night comes use run a fan/dehumitifer if needed ............the size i linked u will do a 10x10x8 room with more then enough power

I know those temps are high but thats not an every day thing, I always keep it between 75-80 when im fully attentive, but i try to have a life i might go out for a day or two and my roomette isnt too competent with understanding how/when to open and close the door.. so it gets a little stuffy sometimes. Co2 is a section of growing im not very well versed on at all. but just the shape of my window plus the sheer cost of the unit plus the added wattage on top of everything else is just a little too much for me at this time

well if your power works like mine ...............the cost of running it spread out as a monthly increase of about 40 bucks

2 600 watt cool tubes
1 115 watt fan
1 75 watt booster
1 65 or 75 clip on fan
plus running a electric still a few times a month (range stove medium high power for 9 hours )

the system i showed u can act as a fan only or it can take out the humity in the air or it can cool the air down

the way i been working it my buddies always want something of mine so i sell it to them 3 times the cost of me making it
1 to cover the cost 2 to double up for next grow 3 for the trouble and time i put in ................right now it cost about 90 bucks a plant and i get from a OZ to 4 or 5 oz a plant ............so they get a oz of high grade stuff for 300 bucks cost is covered and i get free good smoke plus all the extras from the trimings and that

in the end the u are in profit ..............i run auto flowers tho so the turn around is 70 90 days
