Zen 4 heatsinks

2Bak · 3rd September 2002, 09:52 PM

Found two old heatsinks, on which I do not have the heat dissipation data.
They measure H x W x D, 220 mm x 200 mm x 70 mm.
Would there be a chance that they are able cool down the Boz 4 @ 2 x 30 watt or 2 x 25 watts?

one sink for each side

I'm afraid they are not enough. But if you stack them face to face and run a fun they might be OK.

Thanks Peter Daniel

I might consider a fan.
I'm not quite sure what stack them face to face means...

topview:

is that it?

Are silent fans for CPU cooling applicable for amps?

Hallo 2Bak,
i use these sink also with my zen (bias 3,5 A - 43V).
So i´m dissapating 150W. Hot, but under 55 GradC.
Go for it.

I use the size:

H: 250 mm
W: 230 mm
D: 65 mm
Number of fins: 18

Two FETs are fitted on one sink--average 2A each at DC supply of 32V.
It's rather hot--about 50 degC at room temp 27 degC.
Mine should have been a bit bigger.

I recommend you to increase the size.

Hope this helps...

I was rather thinking about something like this and placing a fan at one end.

Face to face...?
I hardly see who have full of hair on the face.
Hahaha...

Good night.

Just a different culture.

well, this will be a hard decision for me to make. Was hoping for a few more of them "go for it", like Orgonoms...

Also found an EI transformer 800VA, 2x18v. Guess you guys will turn your thumbs down on this transformer type also?

Hi 2Bak.

I'd use it if you have room. Why buy when you have a x-former like that in hand.
