hey guys, im sorry i dont post here as often as i should but i been buisy trying to get a computer working so i can stay online. but heres my idea.
i took a styrofoam cup and cut the bottom off it. then put the lower part of the cup on my fop-38. what this does is create a velocity stack in which air is compacted more dense and forced into the fan. i know its working becaue i would hear the RPM's of the delta 38 go down a little bit which means the fan has to work harder because more air (more dense air) is being pushed through the fan blades. un fortunatly i do not have rpm or temp monitoring equipment or i would test this on my system. anyone willing to give it a go on theirs?
velocity stacks are often used in high speed racing boats and cars where air flow through the engine is critical. i seen ppl use them all the time to get more air flow into their engines, and i just thoght about trying it on my delta 38.
the styrofoam seems to dampen noise and as a result, you can still hear the delta and its just as loud, but the whine seems to be at a lower much more tolerable LOWER frequency.
someone pelase test this for me as im really hoping its a good idea. hey maybe joe or ed will make an article out of it??
