Venturing into the unknown- Watercooling

[Spartacus]

i've heard that de-ionized water are not good for watercooling, some say that they corrode the blocks and radiator.

IBM uses it so it to cool their WC'ed stuff so it cant be all bad.

[tom736928]

i read that quite alot of times actually : P , what's confusing me is ,
-should i test the loop with or without hardware during leak test. I'll most probably run the leak test for 2 days just to be safe
-when they speak of cleaning the radiator , only pour the water INTO the blocks and make sure no water makes contact with fins ?
-am i ? or is it justallowed to soak water blocks into bowls of hot water pouring water through the internal parts
-can i power up my computer and use it while doing the leak test (assuming i dont need to attach waterblock to gpu and cpu) ourside of the computer.

With compression fittings , should i use a softer or harder tubings ?

Kink resistance
Best - Primoflex > Tygon > Feser

Stiffness
Hardest - Feser > Tygon 3606 > Primoflex
I'm not so concerned about kink resistance as i doubt i'll be doing close loops.

Lastly, for a reservoir like this, am i able to mount it horizontally ? Or reservoir like this can only mount vertically ?

i would leak test with the hardware in place, but nothing plugged in (if you using your main psu to test) since you should have the stuff installed when measuring for tubing.

you can fully submerge a rad, no issues, just make sure to dry it off good. you want to get some near boiling water and pour it into the rad and fill it. let it sit for 10 minutes or so, then dump half the water out. ideally if you have a clean or clear bowl/container dump the water into that. then shake it like a polaroid picture for 3-5 minutes and dump the rest into the bowl/container. keep doing that until the water in the bowl/container is clear.

if it doesn't void the warranty and you feel comfortable taking your blocks apart, do so. you can inspect the internals and make sure there is no crap left over from manufacturing. same with the pump.

if your blocks are attached to the computer when your leak testing then you cannot (rather shouldn't) use the computer and the whole point of leak testing is to catch any leaks when it's safe. if you spring a leak while using it, you could kill your pc.
testing for a day is plenty and don't leak test over night in case something goes wrong you can catch it. you can, but i don't like to (though i don't really leak test anymore) overnight as the first loop i built one of the barbs broke and split on my desk. that was a fluke, so it's up to you.

go for which ever tubing you want, all of the pc water cooling brands work fine with compressions.

you can mount those res's horizontally (i don't see any reason why you can't) but make sure the inlet is higher then the outlet. to make it easier i would bleed the res in a vertical position first, then fill it near full and slowly tip it over.

I know this sounds silly but i'll run the leak test with just waterblocks / pumps / radiator and no hardware installed first , just to get a feel of it , and then i'll go for the real deal and set it up the way i want inside the case and do another leak test .

Koolance makes a good waterblock acourse everyone makes a good full waterblock that makes one just make sure that you get everything aligned right or the water block wont work =] always double check

[tom736928]

I think i will be getting the EK-D5 X-TOP - Acetal G1/4 Rev.2 as i want to be able to use compression fittings for the pump too. Besides having the ability to add the fittings of your choice , does this product increase the flowrate / pressure head or whatsoever to the pump ?

http://www.ekwaterblocks.com/shop/ek...1-4-rev-2.html

Are there any other similar tops for the mcp655 asides from the EK ones ?

[Andrew149]

Oh so if you want somthing better than the swiftech look at this http://www.performance-pcs.com/catal...1ddc23a09e6f10

[tom736928]

Yea i've decided to go for the 655 with probably the EK pump top. What is the difference between the 655 B and the 655 ?

[Andrew149]

655 you can adjust the pump speed and the 655 b you cant adjust the speed but i have the 655b and it runs at full power and its dead silient so i cant see why the adjustable would be better

[tom736928]

Yeap i've decided to go for the 655 with this top.

Is it possible to connect

http://www.frozencpu.com/products/10...PCA&mv_pc=3209

to the fittings at the corner ?

So inlet / outlet would be directly beside each other while the temperature probe will be on the top.


Or would it be a better idea to place the temperature probe at the bottom of the EK-multioption reservoir?

PS: Ok thanks i'll get the non-adjustable one then

[Andrew149]

that temp prob will be fine but why not get one that goes in a bay like this
http://www.frozencpu.com/products/93...7c17s422#blank

and than use this temp sensor

http://www.frozencpu.com/products/22...or_500836.html

this would be a better way to go

so build outside of the case you mean?

that's fine, but i would build the loop (meaning cutting the tubing to length) with the hardware in place. then you can remove it after and leak test just once. but it's not a big deal if you don't, just make sure no to cut the tubing to short.

yes it will improver performance, but it won't improve as much as when adding a top to the DDC/MCP355 series pumps. tops for the D5/MCP655 are basically for what you want to do with it. add compressions and change the outlet to the side.

as andrew said the difference is one version has a speed control.

the 655 vario can change from 1-5 and the 655 basic is set at level 4 of the 655 vario. so the 655 vario is a bit better then the basic but not by much.

yes you can put the 2 fittings on the same side but you may need a 45 or 2 to get the larger compressions to fit.
and yes you can put the temp sensor on the other outlet, but i would put it in your res instead.

[Andrew149]

I have mine coming from the end of my loop so i know how hot it is and my average is prob 83c and the room temp is 73c

[Spawn-Inc]

83/73Celsius or freiheit? if Celsius something is wrong....

[Andrew149]

Freiheit if that was Celsius i think my computer would be on the oven

[tom736928]

Andrew : i would get that but i have space restriction with the DD torture rack , besides , i think the thermal star temp with bitspower temp probe looks sexy after i sleeved them :P

Am i safe going for 4 gentle typhoon 1450 RPM ones now that i have 2 radiators setup ?
Or would you highly recommend the 1850 RPM ones.

[Andrew149]

i currently have 4 sitting on my desk, i havent tried my 1850's out =[ but get the 1850rpm just incase you need the speed than you can back them down on the fan controller

my feelings.

[Andrew149]

ill have the fans installed once my mount for my 480 rad comes in tmw, yay!

[tom736928]

Can you guys recommend me simple fan controller that can control up to 6 fans, nothing too fancy with leds or too big. Would be plus if theres red / black colour accent to it.
