Small circulating fan to cool amps


I have two tube amps that are on a rack system with wood shelves. Because of the space requirements of all the components on the rack, there is not as much space as I'd like to see between the top of the amps and the under side of the shelve above. Although I have not had any problem to date, I'd like to make sure it stays that way. These amps do throw a fair amount of heat. Has anyone had any experience with a small fan that could be used for ventilation? I looked at Radio Shack and although they had a number of small fans, the smallest and lightest ones were 12v. I'd much prefer to run off wall current, but I don't have alot of space in which to situate the fan. Their non-battery fans were just too big and heavy. Any suggestions?

www.directron.com/quiet fans.html Then in search box type silencer. About half way down you'll see 8x8 ball bearing case fan 11.95. just above quiet fan shootout,read it ..i got 2 of these had a wall wart laying around ,went to radio shack,and got little black box for switch,put velcro on back of box and shelf to hang it ..so i can cut it off,,made a wooden fork like hanger to slide on back of self and mounted fans ..these fans a so great you cant here them run ever..read the shoot out ..greaest treak i know of for cooling..i set mine on my ps audio p 300 and it shays so cool befor it got hot even with there fan in it,shit works
http://store.yahoo.com/directron/sil.html try that im sorry they changed there web sight around..they went down in price get a couble of them .i had a 12 volt ..800 milla amp wall wort around and have 2 fans running off of it ..you dant need 800mas 400 would do.i even got some 2 prong male and female plugs from radio shack and hook 16 gauge wire from each fan about 2 feet long so i could move them around and then unplug them also..hard wired both fan wires in black box where a switch was mounted box is 4 inches by 2 inches maybe..rect in shape,and ran the power wort on other end of box...i did by a 1/8 male and female plug ..over kill but clean
follow me here..if you read the fan shoot out ,you will see these fans move alot of air..alot..you dont have a noise problem read the low db in noise mesurement,make a mountto hang on the back of your shelf mount the fan on your mount mine is maybe 6 inches away from rack ..now i get lots of air,you can feel it when you stand in front of rack..these are the best option,run wal wort only .email me and i give you my number [email protected]
not these fans they are dead still and you cant hear them run,,but you could prevent that by mounting it with some rubber,these fans are not like the radio shack fans,
i would think that forse draft would cause dust to go inside sourse faster,although i have cleaned both pulling and pushing air and they both were dusty,i know when im hot i want fan to blow on me,but im a southern boy ,what do i know?b and bob is right ...no 12v trigger ,use wall wart
