i flushed all my blocks with vinegar+water then just water and im running fine. I think vinegar carries a certain acidity that is less than harmful but more than effective.
IMHO, ram sinks hurt heat dissipation more than help. strip the sinks and through a fan over the top. works wonders.
Hope your EK stuff comes through. I just dealt with EK and from eastern europe to illinois took 10 days. my order was shipped with 6 hours and everything has been smooth since.
possibly flip your cpu block around so the tubing seems to "flow" better from top to bottom. Id also look to move the T around a bit i think that causes a cluttered look.
what additives are you using? pentosin?
does your closet have decent airflow?
1 of 2 things will happen
1) your server will over heat
2) you will steam clean your clothes
Seriously, if the machine isnt going to be cranking 100% 24/7 i wouldnt see any issues. However i would recommend, if the closet has a door, to pop it...
its personal preference, some use 1/4" tubing some use 3/8" some 7/16" while others 1/2". none have necessarily been proven to cool better than the others as there as more factors than just tube size that factor in, like blocks used, pumps, rads, and others.
the question shouldnt be what...
