Water-cooled

Hojvaelde · 19th April 2007, 01:38 PM

Hello

One off my friends got a putter from his company where the CPU (and more) was dead (ligthing).

Inside he got a watercolings system from Asetek. Now I bought the system cheap.

The system are running well. No noise from pump and fan. Asetek told me the system will be able to remove 500 - 600 watt of heat.

Is 600 watt to small to a 2 x 100 watt Pass-labs amplifier?

Regards

Depending which Pass amp you're considering, 500W is fine. Pretty much any of the Zen projects (counting out SOZ) will work well with 500W of heatsinking.

Drop me a mail if you need help.

You'll need to bend a thought towards how you'll mount 24 output devices on the thing. Have you got any specifications for it?

Yep, its just in the "cant quite make it" department. My A-X's dissipates 325 watts per channel and they are rated at (conservatively) 90 watts!! I have big fat heatsinks, (Like any man around here

) and they do get very warm!!! Any chassis under 35 kg's will be too small for a NP 100 watt monoblock. Just my experience!!

Well, I was thinking a Zen amp, sorry, my mistake.

I think I can make a PassLabs amplifier without a heatsink at all.
I take the air from the backside of the chassis and blow the hot air down at a hole in the botton of the chassis.

I think I buy a radiator more from Asetek so I can lower the temp. With 2 radiators I can cool down 1 kW.

The wather pump use 12VCD max 1 amp.

The fan is 120x120 mm and marked 12VDC 0.25A. If i got 2 radiators I only put 6 VDC at each fan.

The systen is close to this:

Could it be this? Only product (discontinued?) they make that has a an icecube's chance in Styx of dumping 600 watts.

I have my doubts about that system being able to cool away 500w of heat. I wouldn't bet my money on it atleast.
3-400 perhaps but it will be warm then.

Anyway, plain oldfasioned heatsinks don't quit on you...fans does...it's just a matter of when, and then things turns interesting
