Last response: in Overclocking

I made the mistake on my old loop of not flushing it when the parts were new so it sort of clogged my old blocks up with crap.

I more or less need to know if it is ok to flush the new blocks like this.

xspc dual drive bay pump/res fill it up with distilled water then hook all the blocks rads up outside the computer run it a few times change the water empty it out put into computer add my fluid and good to go, i think this will works just want to make sure.

I also have 10 feet of tubing how do i flush this?

For tubing, you can soak it in water; rinse with distilled to make sure there aren't any particulate matter/bits stuck inside.

As for rads, you can use hot tap water, soap and/or vinegar mix...fill the rads, slosh them around really well, let them soak 5-10 mins, repeat. Do this at least 2-3 times, rinse well with tap water, final slosh with distilled.

For blocks, you'll want to pull them apart and make sure they are clean and there aren't bits of metal or plastic inside. Both of these are very common inside blocks and are bad on your loop.

At the very least you should rinse them, then.

You just threw away a $150 block? You could have at least sold it...sometimes those gaskets are a pain, but not worth tossing it all in the trash...damn.

It has more issues then it was worth trust me it was the frog block gasket is a pain, nickel was flaking and koolance wouldn't warrenty it so it went into the garbage, lol i have 2 140mm rads i could sell 1 140mm slim koolance copper 1 140mm gtx extreme hwlab

Sounds like some stuff for the 'for sale' forum. There is one on Tom's...but you might want to link to it on here so people know you have stuff listed.

Its one of those things i really dont need the money so why sell it, if you seen how much watercooling stuff i had that i could sell you would be sick lol. I have like 40 some 45 degree bitpower black 1/2 id 3/4od fittings brand new buncha 90's, its very $$$ stuff on frozen cpu or anywhere eles. lol! i paid like 15$ a pop for them.

Why did you spend so much money on stuff you didn't use?
June 21, 2011 2:48:23 PM

Since it takes like 1 week to get watercooling parts and I have multipul watercooling rigs, I though it would be better to have things on hand, If i listed the fittings on here they would sell like hotcakes lol.

if you have problem with the o-ring .. silicone (water soluble )grease helps ,when you inserted back in to the block start from the corner ,you can hold it down by putting something on top in one place and work your way around takes time and patience (don't twist the O-ring ) For flushing RADs fill up with hot (not boiled distilled water for 15~20min),drain it fill up again 40% only and shake the RAD like crazy..if you really want to add something to the water like vinegar more than 1:10 ratio and only for very short time ,make sure you flush it multiple times with distilled.The safest way is hot distilled +1tbs of pine-soil followed with clean DW
have you open up your blocks ?

June 21, 2011 2:59:15 PM

The new ones get here tommrow, its a danger den copper base/acrlic top, ek gpu copper/acrylic top. simple o rings in these it looks like my koolance gtx 580 card cover had so many 90 degree bends.

your pump is weak ,so try to avoid 90/45deg fittings ,1~2 90 or 4 45 deg is ok but the more you add the more restrictive your system will become

Thanks for telling me that if the flow is to slow i will buy a new pump, but i think it will be ok. What are some of the higher flow pumps out there?
a b K Overclocking
June 21, 2011 3:27:37 PM

for the highest flow D5(MCP655),for restrictive loop PMP-400 (DDC 3.25)
I like PMP-400
June 21, 2011 3:29:51 PM

Can you get me a link to buy the pmp-400, I'll just order one today, if I dont use it on my current computer I'll use it on another one.

pmp-400 is the same as the Swiftech 355.

one difference can open up that bad boy without loosing your warranty and i like the KL top
June 21, 2011 3:36:06 PM

ahh, ok I will have to see, alot of other people told me the 750lph=200gph pump would be fine for my setup.

Yeah I doo like the look of that pump/res you linked.
a c 324 K Overclocking

Ortoklaz is correct on that...if you are wanting to use it with a top, it's a good route to go.

sure it would be ,but i thing your pump is going to haven or you have restricted your set up somewhere look at your temps
June 21, 2011 3:44:06 PM

I kinda figure it out after I took out one of my blocks its was full of green stuff there was to much constriction thats why my temps were bad.

what's your coolant ?

How bad was it? It would have to be pretty bad to limit your flow rate...

I hope you not adding color ...
June 21, 2011 4:15:07 PM

Nope that is why I bought it clear. any way I was told it was good fluid by alot of people.

Distilled + kill coil + PTNuke = most recommended for water loops. You can run 2+ years with just that and never see an issue.
June 21, 2011 4:23:00 PM

Yeah alot of people have told me that, I'll stick with my feser one and primochill lol. I dont keep a computer 2 years so doesn't matter lol!

^+1..if both PT/Silver ~for nickel (1drop of clear PT)

I'll stick with my feser one and primochill lol

FeserOne is the worst offender for precipitating out and clogging blocks under load temps...even in short periods of time ...less than 6 months.

@ OP try to run distilled for a change will see what are we talking about lol
June 21, 2011 4:43:12 PM

I've run distilled before worked ok makes my pumps noisy to thin of liquid.
a c 324 K Overclocking
June 21, 2011 4:45:27 PM

That sounds like a dampening issue or worn bearings.
June 21, 2011 4:49:24 PM

Only makes the noise with D-water.

How/where is the pump mounted? XPSC bay? Sounds like vibration...thicker fluid to simply quiet a pump will cause your pump to die faster. Check into some sound/vibration dampening mounts.
June 21, 2011 4:59:12 PM

This is starting to get to hard lol my last blocks rad lasted me 6 months good for like 700$, it died this month so what i dont have time to deal with it and i have more then enough money to replace this stuff lol.
