Well, after some testing I can say that this block performs about 3 - 4 deg. C better than my previous block. I'm a bit dissapointed, expected a bigger improvement cause I know the other one don't was a great performer.

Anyway, this is only the first prototype, there’s a lot of tweaking to do. I found that the exhaust system ended up more restrictive than expected; the id. area of the four brass barbs is equal to the id. of the main barb, without compensating for the increased drag of the smaller hoses.

In the flow tests I made my first block take 32 seconds to fill one gallon, the new one outputting water directly to container takes 35 seconds, and when assembled with the “flow integrator” separated by 15 cm of hoses takes 45 seconds. Ouch! My pump is an intermediate model rated at 12w, roughly similar in specs with an eheim 1048.

What I’m sure right now is that my asus mobo is an absolute crap at reporting temps. It’s an A7S333, bought it because was cheap and promised diode reading; but in fact it’s only used for security shutdown and uses in socket for temperature report. Besides, the ambient reading can’t be trusted at all. The only temp I’m sure comes from a trusty old analog (mercury) thermometer I have in my res. I know that motherboard testing at all (as BillA would say) is flawed, but this are more like blind tests.

So I ask for suggestions about some mobo in the cheap range that really reads the diode, I’m going to upgrade as soon as I found someone to sell this one.
