Which way to point the air flow of this cooling fan?

[TheNinja]

Ok, so I figured I would blow the air from the back of the amp across the circuit board. However there is a big metal "wall" between the fan and the circuit board, which is really strange to me.

Which way would YOU blow the air?

Top down View - the metal "blade" looking thing by the fan is a "wall"
Side View #1 - the left side of the picture is the back of the amp
Close Up - the right side is the rear of the amp
Rear Shot - can barely see the fan
Top Down view - fully assembled - see the top vents

I'm figuring the metal wall here.

However, it's a shame the fan is so far from the vent, so it won't be greatly effective. Neat if you could channel the air flow from the vent to the fan, so it sucks cold air in.

Well the fan is actually really close to the vents. The fan is just so far from the actual circuit board. Add to the fact that there is a giant metal wall between the circuit board and the amp and I am thoroughly confused. Basically the vents on top and the vents on the back are probably 6 inches a apart and the fan is inside the case probably 3-4 inches from each of them. Grand air flow path of probably 7 inches....

When you are done overclocking that baby, will it go to eleven?

I can't tell there. Normally a fan is an exhaust fan, but it's so small that I can't see it overpowering the warm air's natural tendency to exit through the top of the case. So it might suck in.

I doubt it's critical if the fan is that small.

Of course! I can't be jamming out on 10, just wailing away at the edge, all the way up, all the way up.....and then where can I go from there???

The wall is a heatsink Einstein

Yes, having the fan blow directly on it is the most effective method of dissipating heat (short of putting a bigger fan in there).

Ninjas typically are not known for their abilities in electronics - though we do delve in all aspects of life we stick to more traditional things like flipping out and frenching. If you are right though, and the wall is a heatsink then blowing air directly on it would probably be the way to go. Brilliant!!

Dude, you're supposed to let him move the fan or take out the "wall" and wait for him to come back saying his amp fried! You ruined the fun

Eh, I already fixed am amp for one guy at the office. We added a nice 4" fan to keep it from frying again

Man, Delleet why would you want someone to burn up their amp?...you're such a nutbucket....and Nutbucket, thanks for the info, at least you actually aren't so much of a nutbucket. It's just kind of fun to say too....nutbucket!

Well, I dunno what the deal with your amp is. For this guys it turned out both power transistors were blown along with the transformer. We noticed once we replaced everything that even it just a few minutes driving some small speakers the thing heated up pretty good.

EDIT: Don't wear my name out I just remember I was in a UT clan with some friend back in hs and I ended up as nutbucket. Guess it stuck!

In your case, the goal is to cool off the heatsink. This will be most easily accomplished with the fan blowing at the heatsink.

thanks everyone for the input. I didn't realize the "wall" was a heatsink. It doesn't even seem to really be attached to the circuit board or anything hot. I don't get how it would collect heat. I guess just b/c of the type of metal is attracts the heat and then the fan blows against it and the hot air vents up??? Man I really learned a lot on this project. Long live Do-It-Yourself projects.
