Can you have that 4U 400mm Dissipate chassis with UMS heatsinks? I like the 400mm depth and 40mm heatsinks, but I don't think you can get 2 X 200mm heatsinks (per each side) with "UMS" pre-drilled holes..??

Anyone?

what I'm seeing in UMS pdf , I understand as UMS is made for both 300 deep and 400 deep

excluding one central hole , no reason why 400 deep can't be made from two pieces ..... however exact deal/arrangement can confirm only someone from DiyA/Store team

ask them in Store related threads

Is it really necessary to hava 4 Units height or is a 3H 400mm Chassis also OK for a two channel Aleph J?
I love the smaller width of the Mini Dissipantes. The space inside for the power supply is more than enough in there.
Plannes is to use Kapton Isolators for the FETs which should Keep them cooler and eventually a thick copper "heatspreader under them.

Dieter

you can squeeze it even in 2U/300

then fans are your only option

for 3U/400 ..... summer in Europe - Babysitter is a must

If you again have the same summer temperatures you had this past summer in Europe, my suggestion is, no.

Biggest enemy to heatsink doing a good job is ambient temperature.

Thanks for your replies.
That's true, it was a hot summer, but I loved it.
It will not be the only amp here. If it's too hot I can use a Hypex class-D amp instead.

Dieter
