Prons and cons of fanless water cooling systems. - Page 2

post #11 of 27
i would recommend against a completely passively cooled setup, get some extremely quiet fans. even a tiny bit of airflow helps a lot compared to a completely passive setup... some gt ap11's or 12's should be silent and still move some air through a rad

Yea just realised got very sad. Trying to find complete cooling external cooling system on a Market. Why they don't sell anything like that ? So easy, all included (pumps,radiators etc) and convenient to use
My budget is up to 200£

Still need blocks with this option.

However, the radiator is aluminum which when mixed with a copper block will cause corrosion. I'm not too familiar with how big a deal that is, someone else may be able to chime in if it's a total no-go or just needs extra maintenance.

A buddy of mine has a passive rad, it works about as well as an H50. OC very hard and temps will shoot through the roof, especially if you're going to add a GPU into the mix. Gentle Typhoons and other low RPM fans are so quiet though you could achieve near passive volumes with a triple or quad active rad. The kind of specs you're talking about just don't say "passive" to me.

Problem being that most if not all rads designed for passive use are aluminum...meaning you're stuck needing to use mixed-coolants. They're also more expensive than normal radiators.

I didn't know, that if your system mixes cooper and aluminium surfaces it might cause corrosion. Description for this unit not very informative in terms of what you need extra.
So if I'll buy two aluminium gpu blocks and one CPU this unit should handle all well and keep things below 0c ?
It says 700w could you clarify this little bit ? It is like general guidelines for how powerful your system ? I have 750w PSU.
Oh and one little extra question: what is more efficient cooper or aluminium block for GPU. I thought cooper better in thermal conductivity versus aluminium.

My friend:

1) PSUs are rated by electrical output

2) W/Cing systems are rated by thermal sinkage. Determined by coolant, rad size, and number/type of fans...as well as efficiency of blocks.

3) You want copper. Aluminum is used by cheapskates, and *will* cause galvanic corrision in your loop unless you're using anti-freeze mixed coolants.

4) Mixed coolants preform worse than straight distilled water in thermal performance.

No question copper is better. I could be wrong, and I'm sure someone will correct me if I am, but I don't think that being rated to 700w has to do with the PSU. It has something to do with the output of the components in terms of heat generation I think. Also, it might not be the easiest thing to put together an all aluminum loop (most quality components are copper). You really might want to think about going all copper, EN, or some other noble metal. As far as I understand it, aluminum just isn't great for loops all around. Again, I don't think you should be considering a passive rad for your system.

Then I'll bother you with one last question if I may. This external system in the link below seems to me a likely candidate for the job. Would you kindly confirm that this unit can cool down two 570 and one I7 chip ?
I understand that I need to purchase three water blocks in addition to that. It also says made of cooper. If you agree with my choice can you think of a cheap place to look for ?
You must be well aware of some specialist places. I live in United Kindom.

Thank you in advance.

Judging from a quick look at the product page and pictures, it appears that solution only has a single 120mm rad, which will not take a CPU and 2x GPU very well...
