I really like the machine you built.
Looking really good Capt!
Are you thinking of another modders post? 3e I believe?
I WAS looking at this log for the other statements, though.
Well, I'm at wits end right now.
Both block tops are dead due to complete material failure. The grade of polycarbonate I used apparently couldn't withstand the antifreeze. I caught it before any hardware was killed because I was investigating the leak near the video card.
I'm really mad right now and I don't want to look at this machine for the next week. I'll make new waterblock tops once I stop feeling like throwing this machine out of a third story window.
Lesson here: Only use Delrin, Brass, or Copper to make waterblock tops.
Man, that bites. Hang in there, I'll wait. I sure am glad I'VE never broken anything...
nasty...... that sucks.
keep going man, it's just a (big) bump in the road that is modding.
if thats a big bump, was it a cow lieing in the road? lol
shame that had to happen, wont take long to fix it and the other blocks.
wow that is a real shame cos those blocks looked good!
but i reckon some block tops made from derilin or copper would look great as well!
I was a little worried when I saw that block TBH just because it's suck a small footprint for so many holes.
The issue was the ethylene glycol destabilized the molecular structure of the polycarbonate. I knew this was an issue if I were to run alcohol in the loop, but I didn't think antifreeze would do the same thing. Now I know for sure.
I will be making new tops out of black delrin in a week or so.
Hmm, what type of polycarb did you use? I might know something that would still let you use antifreeze, but you might want to look at something like PC Ice if you're going for anything like that... It's better on your pump, to boot.
I already have some black delrin coming in the mail.
The pump isn't going to have any problems. It's made out of PVC and Polyethylene.
I like the way the case looks, like you're able to throw it through the room and it would still be in one part
Looks good but the pics are too dark to see it in full glory
Why do you put anti-freeze, just 100% demineralized water. I am no professional, and never got a water colling system, but I mean it's not like it will be cold at 0 degree Celsius, all you do is pass water in a grid to cool it off. All you need is to NOT to not leave minerals deposits inside the pipes which will turn them yellow/white at the inside (bad for transparent tubes), reduce water flow, cause the pump to force (all that should appear over the years). Oh and 100% demineralized water does not conduct electricity... (notice, I said 100% demineralized water, not 99%)
Therefor you can fill your computer, like a tub, of this water to cool it off, and it will function without problem. ALSO, this water doesn't boil, like vegetable oil you buy.
It's the minerals that get active in the water that makes it boil.
heuuu ok, I think I'm getting off-topic here...
Sorry, back to the subject.. yea what is up with anti-freeze in you water colling?
You may want to calibrate your monitor.
Corrosion inhibitor to prevent the water from oxidizing the copper. Or should you mix aluminum an copper in your watercooling loop you will need a higher concentration of anti-freeze to inhibit galvanic corrosion that could eat away at both metals. The reason to use deionized water is to prevent lyme and calcium buildup. 3 to 6 drops of iodine is added to prevent algae and bacterial growth.
Water isn't conductive itself, but the crap that will eventually be floating around in and be dissoluted in it will be.
The only cooling setup that does not require antifreeze would be an evaporative system. But you will still need to use deionized water with several drops of iodine.
For those of us with mixed metal cooling (I've got a pair of Koolance 8800GTS blocks waiting for barbs for the SLI connection) it's absolutely necessary. That, or a nonconductive fluid that inhibits corrosion. Also, it's not just that you clean it properly. Copper and other metals will form ions after prolonged exposure, and the ethylene glycol will keep them from galvanic corrosion and eating holes in your stuffs. If you want more info on that concept, google metal nobility.
Sorry, just had to do it.
On with the show, bro!
It is, works fine on all the other pictures I look at, just yours seem too dark to me.
I always wondered... How many times you need to fill your water tank per year?
It really depend on the side of the reservoir or t-line. You just top it off every few months since a tiny amount of the coolant in your loop will evaporate out through the tubing. If you have to top it off more frequently than once a month you may have a leak somewhere.
