i'm planning an F5T next, and trying to make something with a little more WAF,
see below this water filled heat exchanger.
I was thinking of mounting this to a base with the circuitry and transformer in it.
do we think it would have enough cooling capability?
it's available in lengths from 500mm to 1000mm tall, and is 100mm diameter.
a small pump would be needed but i'm hoping a circular base maybe 200mm diameter by 100mm tall should be enough to fit everything in?

An externally hosted image should be here but it was not working when we last tested it.

Hmm strange. I can see them from my phone also.
Here is the URL if the picture

I'm not sure, I think I'd have to buy it and see.
The good news is 500mm length is around 30USD going up to 70USd for the 1.1m version.
Do we think it would be up to the job?

Nice. Can you post a dealer link?
Can anyone comment on how much noise the applicable pumps make, advise a manufacturer?

A shorter heatsink is better in many ways, heatexchange and tipping over.
I´d try 4x0.5m for a F5t .
A nice wooden base with the 4 sinks mounted on ?

Really 4x 500mm !!
I was thinking 1x 500-700 for an f5 running stock voltage but double output devices/ bias.
Is this enough?
The diameter is 100mm and the water flow should ensure even heat.

I can't see how you intend to mount the semis to it to use its heat transfer capacity to its best.

It´s watercooling so you can get some of the blocks used for graphic cards nice and wide better then the square CPU ones.
Question was about F5T so depending on version and voltage 4 seemed a good choice.
My guess was that one was able to handle <100w and adding a margin for a nice home and wife aproved temperature rise of the sink.
If you take the (diameter-fin height)x3,14 then you get an aproximate of what a flat sinks with should be.
A tall sink is less good then a short wide and so on.
But this is just me thinking out loud.

Do you realy want the noise of the water pump?
The good ones aren´t that bad, in an normal home environment they dissaper in the background noise.
But when dead quiet you hear it !
Take it one step further attach it to central heating.
F5 powered heating system......with my plumbing skills it will backfire and i´ll end up with a hole lot a water in the livingroom 😱😱😱.
Someone that manufactures heatsinks for highpower LED´s should be able to sell you something similar ?!

The pictures in post#1 showed a PC water cooling system similar to the Zalman Reserator :
::: Zalman, leading the world of Quiet Computing Solutions :::
In general, heatsinks with such long fins and narrow fin pitch are not very efficient radiators for natural convection. If you are willing to put a fan at the top to extract air flow, they can dissipate a lot of heat.
So if you do want to use them for a Class A amp like the F5T, you should make a very small amp case but with water manifold running through the MOSFETs, and probably put the pump and the radiator outdoors, at least outside the listening room. When using such a system, there should be some protection to detect loss of water flow / pressure to shut down the amp before it gets too hot.
I serious thought about this a few years back, but decided against running 4 water tubes from my sitting room to the balcany.
