    i have two amps mounted in a small cabinet that are in dire need of some circulation. the stinger option below doesn’t look like it would move as much air compared to an average computer fan.

    thoughts?

    "squirrel cage fans" i don't remember the real name for them. they will move almost as much air as a 20" box fan. those are waaaaay better than computer fans.

    i'm guessing you are talking about the stinger cooling fans... no clue, i was looking around the web for options and found those.


    found this fan

    I've never seen the tube ones before.

    Computer fans aren't going to cut it.

    The pic in post 4 is a centrifugal fan, likely to be better than case fans as well.

    those tube fans are weird, lol

    how are overheated are your amps getting anyway? arent amps generally suppose to keep themselves cool?

    Well if they are in an enclosed area, im guessing maybe a boat? You are going to need to figure out how to get some cooler air from the outside into the cabinet. Just putting a fan on the amp probably wont help your situation if the air that its bowing around is the same temperature.

    if you look at the pic on the top of this post you will see about a 3" gap above the amps. that is were i will be directing the 'fresh' air from.

    real hot, if i remember i will take a thermostat out with my on Thursday.

    if i run the fans to the amp power and ground do you think i will get any noise through the speakers?

    HOW MUCH thermal transfer are you looking to achieve? If you want to get REALLY serious you can run coolant tubes through your amp box. Bigger/competition systems...that is common because you have sooo much crap enclosed in a small area. Then you can dress it open so that the coolant tubes actually add a visual element to the system. Picture anti-freeze illumanated by a black light. Nice...

    i haven't seen this since 1996. most of the guys that i see building big comp systems hardly do any finish work, let alone take the time to do liquid amp cooling.

    edit: and the last amps that i can recall that were worth liquid cooling were PPI art series amps.

    .

    proper heatsinks and transformer tech should take care of most amps, after that its just ensuring the compartment has some sort of ventilation to esnure heat can escape in some direction and not become trapped in a certain space.

    i see that the amps are mounted to a wall, does the panel that hugs their mounting location generate a trap for heat? if so id just make a mounting frame out of MDF wood and angle mount them so 90+% of the amp is exposed to open air or use some sort of spacers.

    and yeah like said before if the air outside is really hot it makes things harder, if its in a car you can hope on A/C or something similar.

    Liquid cooling has/is generally used in situations where "proper ventilation" is not possible due to design constraints. Plus, for some who care for the look, they like what can be done (visually) with the setup. Heat sinks can be almost completely ineffective if the amp is mounted in a poor orientation (think upside down), of in an enclosed area because once the heat sinks heat the air around the amp to the same temperature (or close to it), they have nothing more to "sink" the heat too. This is why cars (more commonly older) can overheat in bumper to bumber traffic, they don't have the proper flow through the radiator. Ever drive an air-cooled motorcycle in the city on a hot summer day? Better keep moving!

    It isn't for everyone...just like

    Rice vs American Muscle
    Ford vs Chevy

    To each his own...I never did understand why some people would knock other people's custom work. Knocking workmanship...yeah I understand. But knocking personal preference...why? You don't like what I like...so what.

    Oh well. My car audio days are years behind me.
