My first cooling set up ;-) Zalman Reserator1 v2

if i was to use the zalman res 2 with a copper waterblock would i be okay using G11 (antifreeze - prevents corrosion) and deionized water in the mix?

getting my unit 2nd hand at the weekend and ive got some G11 being delivered today so just wanted to know if it was okay to run (will be run for about 6 month topps)

Thanks for any info

Galvanic corrosion only occurs with dissimilar metals in direct contact and in the presences of a electrolyte.

No contact, no GC - note if you have metal fragments/filings in your loop this will give you GC issues especially if they get stuck in a copper block matrix. But they will only affect the aluminium increasing the life span of your copper block.

Normal corrosion (rust to you and me)
It happens - with aluminium in a non abrasive area it's a good thing as the 'passivation' of the metal acts as a shield to further corrosion (anodising aluminium is taking this one step further and then 'sealing' the surface with a different compound - Teflon for example)

Stopping it
Coating the metal - Plating, painting or enamel - in WC’ing terms always with plating - done by most of the aluminium block manufactures usually with zinc sometimes gold.

Using corrosion inhibitors - (antifreeze, G200 etc) These form an electrically insulating and/or chemically impermeable coating on exposed metal surfaces, to suppress electrochemical reactions (hard water can do this btw but calcium deposits are not flow rate friendly) And deionised water goes one step further by significantly reducing the ability for the coolant to be a electrolyte.

I use a Res2 with four copper blocks – not had a problem with corrosion.
Due to the Zalman’s flow rate Algae with be a bigger issued – again the G200 or nuke will solve this

im not sure whether i want to get this external one kit or get an internet kit. Whats the advantages?

Do you mean passive external watercooling and active internal WC’ing?
Not seen an internal passive WC’ing system as the inside of a pc has a higher ambient temp. The hybrid Res XT and can be installed internally but it uses fans.

well ive got the res2 coming on saturday and i'll be using the standard cpu block and NB with a copper gpu block. ive got my hands on some g12 to stop corrosion, alge shouldnt be a problem as the tubes/water wont be exposed to much/any light and the loop will only stand for 6-8 month anyway.

Thanks for the advice and im just hoping that the res2 will be able to cope with the 3 things in my loop.

out of interst what are you cooling with your and what are your temps?

yerr sorry. Im not sure which is best. I would like the res1 V2 cos it will be practically silent but on the other hand if i have an internal w/c kit everythingwill be in the case.
 
XSPC edge - [email protected]@1.3v - 46c load (F@H smp)
DD Maze 4 - [email protected] - never checked
Alphacool SilentStar (twin blocks) - Raptor - 34c
passive (air) 8500gt
Also use 3/8 tubing

I do have two rads in my loop but some numbers from my build log
top set with just the Res2 bottom set with Res2 and skirting rad

Silence - passive external wc or passive internal Air cooling
quiet or proformance/small footprint - internal active wc
cost/build friendly/no additional footprint - active aircooling

All three can deal with a oc'ed quad running SLI/Xfire or a underclocked HTPC

Budget and ambient noise level are bigest factors IMHO when selecting cooling strategy with PAV a very close third. For example if you live in a city centre fans at 5v or even 7v are 'practially' silent so why spend more on a passive solution.

PAV - partner acceptance value - passive cooling scores very highly :D
