Default Heatsink, the next step into near future

In 1963 i started to make some different assembling, i show them to friends and they laugh as a hell...... was a noisy hahahaha...hohoho....hhuhuhu.... and i telling them, no!, assembling this side is not crazy, it is easy, faster, better and will be the future.... they said i was lazy, because not holes, not inverted images in copper circuit board downside... they said...have to make holes.... board have holes.... have to solder other side, solder is made other side...and i telling them WHY?

When SMD appear, components horizontal, flat, as i done before, no more laugh!.... where are those friends?.... only one i met, this one remember and congratulates me.

I have not good knowledge related electronics, also i do not know how to transform in money some good crazy ideas...but always having ideas, and discussing the "status quo".... all the things people do not like to discuss i am always checking, because always i can find mistakes...people repeat others do without think about that.

Second i decide to construct one unequalizer, 8 stereo channels plus and less 12 dB controler.... to match the sound to my furniture, carpets and damn speaker (all them bull S--t)....again hahahahahaha!.... try to sale idea in bigger capital and hohohoho.... this way i made mine and forgot those thing.... one year and appear the Japanese Equalizer..... and i became nervous.... not equalizer!...the music came already equalized, equal the levels.... that's he meaning... this machine unequalize...not equalize..... i found the friends... and they respect me because i had first the idea.

Now the wind tunnel, the small fans i have them in trash.... in cities giant trash... i paid people and they separe to me..... go to soap and air with pressure... and them i test them when dried.... can buy 50 for a dollar...normally can have one third good to use, without noise, and good looking ones, without rust.... this way small aluminium in sandwich, one fan each side.... if inside a wooden tunnel better, but more noise..... open will work reasonable too..... inside enclosure, size diminishes, only two holes, same fan size its ok....one to input wind other to output wind... a small sandwiched heatsink can hold 150 watts of heat easy....in my environment this one without fans will dissipate 30 watts more or less... take a look, a 75 RMS power amplifier can have this size.... glue the small board into the heat sink, two small microprocessor fans, and a outside tube... excluding supply, and somepeople can make supply smaller than that (EVA and many others), you can have less material, less weigth, and please, forgive me you all friends..... those insulators....i am sorry, but a hell with them!...no need this thermical resistance.... put transistor directly in heatsink!.... small conical automatic screw... the one that will make his rails.... and ready to put power on it!

Isolate the plus side related the minus side with wood, and also this tunnel sink related the metal or wooden or plastic chassis you have.... simple, cheaper, smaller.

I am sure, if not happen already... tomorrow you will not laugh from Destroyer...i am sure about that.

regards you all hahahahahaha...... i will be the last to make that.... and this is the best moment....huhuhu...hohohô!

Default Sometimes, 100K is not enough...but this is needed

Because technical reasons...cannot be so big.

Yes its always good to sand the bottom of heatsinks and the bottom of the chips.

Takes maybe 10 minutes and usually makes a noticable improvement in temperature.


I just go with 600 grit, I guess higher would be better. Done on a very flat surface (glass is best, or just any countertop).
