How quite are these?
Also most water blocks seem to be copper and it's a bad idea to mix metals so are there copper rads? or do people find blocks which aren't copper?

The only rads that aren't copper cored are the passive aluminium ones eg. Cape Cora and Innovatek.
The bayres is near silent if there is no air trapped - if there is air trapped, then it's REALLY loud, but at least you know to bleed it
I wouldn't recommend a Bayres though - way too finicky for me.
o dear lol, i wanted to get one but if it means mixing metals i dont want to but then again dont anti-Corrosion fluids stop it?
can metals be mixed with the correct inhibiter or is it looking for trouble ?
Supposedly they can, but I wouldn't trust them. There's been enough threads showing what can happen after only a few months. Even with special liquids.
How do you mean fiddly?
Looking for a neat and easy cooling system.
was thinking 2 bay res with 2x240 rads and 800rpm noctua fans. one loop for the cpu and one loop for the gfx and maybe the northbridge, depending which asus board I get.
Well I'm not the best at English as I have dyslexia, but go ahead take the **** and critisize me if it makes you fell better - no need to be a knob about it.
and no need to post useless stuff. with LOl OMGZZZZ....
aye, i work on boats which can suffer from electrolysis and i suppose it would be similar with a water cooled computer.
we have anodes on the engine which are in the heat exchanger, the engine is fresh water cooled but the fresh water is cooled by sea water by means of a heat exchanger stack, there are also anodes on the hull and stern gear which are required to prevent major corrosion.my home harbour is in fact very bad for electrolisis probely due to all the rubbish which has been dumped over the years on the sea bed, sorry bit off topic thereIt's exactly the same - except usually on a metal boat or ship they have a big lump of sacrificial zinc somewhere that provides cathodic protection (sometimes it's just zinc paint now though). Check out the thread below for an example of what happens when you believe what the manufacturers tell you it's OK mixing metals..

The Sacrifical Anode was more for Marine Environment.
I worked with Diesel generators for 15+yrs up to 16 Cylinders at 15foot long and the Engines/Cooling Systems just like a car have Alu/Copper/Alloys/Rubber/Plastic/Glass and it never causes any issues with proper Antifreeze/Summer Coolant (also Inhibits).

there will be anodes on the generators![]()

Cheers firestarter, what rads do you run with that. I do have room to fit 2 x dual 750 bays.
