After putting in the new crossover and hence discovering that I could turn the volume "way more up" without seeing distortion due to speakers being driven beyond their range or speakers overlapping and getting muddy.... i overheated the poor "widdle" blue thunder...

alas - i have found the fix...

120 mm / 120 mm and it moves 80 cfm. that'll do 'er.

it's solid aluminum too... so it'll soak up more heat when i bolt it to the front (finned part) of the heatsink.

just to be matching, i got a little one for the other (smaller) blue thunder amp... it doesn't need it, but i want everything to look the same.

    youre putting it ON the heat sink? blowing away or towards it?

    wouldnt you be better off putting it on the side of the amp perpendicular with it?

    I second what cody said, blow air across them that way, it works better to blow on the hot spoon of soup than to try and suck the heat off of it :)

    i see where he's coming from, though, sinking right into the fan structure... the question is, will that localised cold spot pull in enough heat from the rest of the case to even it all out?

    the amp has ribs on the top of it, about 1/4 inch deep. by bolting the fan directly to the top of the amp (the fan is all aluminum so it just increases the heat sink area) and having it blow "away" from the amp or "up"... what it will do is suck cold air toward the case, through the fins, under ther fan body and then back up and out... fan is almost 5 inches by 5 inches.... amp is like 10 x 10, so it'll cover a good hunk of it.

    it would be better to shoot air across the top of the amp, but 1) i dont have any way of mounting such a thing without ruining the cosmetics and changing ****... and 2) most of those small blowers are noisy as hell. i don't even know if this is going to be quiet enough. if it makes too much noise, then its plan b --- liquid cooling plates on either end of the heatsink. if i go that route, i'll jsut do all the amps .

    ive been looking at a liquid cooled system for a little while now but have yet to see someone implement it other than 1 car...but it was just some random pictures i saw, nothing detailed and no "how-to"

    cake work dude... get the stuff that they use for computers - like hard drive coolers (look like panels, outa plastic, say 3/4 inch tall by 4 inches by about 8 inches) or other big ****, and screw it all down... then run the tubing to the same pump/radiator system you'd use for a comptuer but just get a 12 V adaptor for it...

    wait - brainstorm....

    wouldn't it be "way pimp" if you did the plastic coolers and ****, filled it with anti freeze, got a transmission cooler and put it in front of your truck, then bought a one way in pump that ran off 12 V power... oh man.... oooh man.... SOOOO COOOL!

    if the fans are noisy, could you not use some diodes in the power line to slow em down a bit?

    diodes will just drop voltage - you might as well use resistors in that case or even a pot as a speed controller.

    true... but ive used them on a noisy case fan once, really quieted the sucker, and put some laying diodes to use :)

    well u're dropping 3/4 of a volt everytime you slap a diode in there, so ya - its an easy way to drop a fixed voltage without having to tie into ground. and there's virtually no risk. its a good way of doing it. only time it would be a problem is if you were at say 12 V and wanted to drop to 3 V, then you'd have to use like 6 diodes.
