its not aluminium lar... if u use aluminium ur gonna have a BIG problem with corrosion as aluminium doesnt go well with copper.
the storm's and apogee's upper body is made out of Delrin Acetal

If using coolant with corrosion protection then it's OK wat. Anyway alu parts for water cooling is always anodized. Coz car's water pump is also alu, rad oso alu but all protected by the coolant.

Kinda regretted buying that MCP650 (D4

Should have gotten a MCP650/DDC instead and fit it with this modded top.

It's similiar to that systemcooling mod that makes the DDC a MCP600 beater and changes the barbs to 1/2 as well.

*Sigh*

ordered 5 more of the panaflos.. lol i love them

hydrX not good? ianho, did you really see the white growth?

The problem is you have copper, a known material that easily cmes into contact with other materials chemically and for closed compact loops, corrosion can bild up easily as the temps between idle and full load remains a conducive temperature for algae growth and deanodising of the aluminium. Car's water cooling does not have copper parts internally AFAIK.

so that means we should not use hydrx?

or what?

Dude, that's a pic of the MCP350 with mod top lar.



My tubes were all coated white after 1 week of Hydrx but there wasn't any actual clumps of growth like that guy experienced all over his system. I flushed my system with batt water after draining the Hydrx n there was no furry stuff coming out. But I din like it coz the tubes became a blurry white.



I don't think alu in the loop is a big deal lar. I mean look at the Zalman Reserator. It's a very good example of a great big hunk of alu in the loop. It's also got alu VGA n NB blocks. As long as u use anti corrosion coolant it's ok.

Typo lar...I did say DDC wat right.



Dood..the sarge is trying to say--> Mix metal = big boo boo

I know wat he's saying. That's y I use the Reserator as a good example of mixed loop. The reserator itself is a big hunk of alu, CPU block is copper, VGA block is alu, NB block is alu. So there's both alu n copper in the loop. The Gigabyte kit is also using alu rad with the copper blocks. Coolermaster Aquagate oso got alu rad with copper block. Many people using custom built WC oso using alu reservoirs. Even the teutonic water gurus Aqua oso use alu reservoirs. As long as using proper coolants then it shudn be a prob unless running just batt water then only it'll start to leech.

Well we're talking in the long te3rm like say 24/7 at least 1.5 years. It's not for no reason the hardcore kaki's in XS are saying a big NO to mixing and matching. It's pure secondary school cheamistry as at a certain temperature and prolonged submersion of water (which will ionise) will cause deanodising and having elements of aluminium getting into the loop. and when that occurs, trust me, you don't want to know it's effects onto ur copper block. Anyway, seen the machining quality of the Apogee? Ain' good itseems. Frightening in fact

yeap. right.

btw, ianho, it doesnt matter whether the coolant has anti corrosive properties. the fact is, it only slows down the process. in a long run, if the components surface are improperly treated, alu components will still get corroded (will explain further down). on the other hand, the reserator's copper based CPU block is GOLD PLATED if i recall correctly. so that explains why it can be used.
you will never see people mix copper and aluminium without having either components plated with another suitable material like gold, silver, or nickel, or anodised.
try mixing bare aluminium and copper together with "anti-corrosive" coolant and you're bound to see some results after some time.

almostthere: yeah, saw the apogee machining. not a good sign.

I understand what u guys r saying. But of course dont use untreated aluminum mar. All WC alu components r always anodized. If u look at the Aqua Computers site, u'll c the reservoirs r alu. So there's a 1337 WC company using alu components in the loop. U can also see that CM uses plain ol copper in the blocks as u can c thru the acrylic that it's bare copper inside but the rad is still alu. N it's a closed loop that's low maintenance n nonid to change water sumore.

The point that sarge brought up bout 1.5 years oso applies to lazy buggers oni. I mean, how many of us allow our WC system to run on the same water for even 6 months? I don't n I'm sure most fellas don't either. Coz if u leave the water in there that long it's gonna get real nasty.


edti: I just found the ultimate example of alu n copper in a loop. It the CPU block itself with both materials. Check it out here.

Click on products, cpu waterblock n look for their ultimate CPU block which is the Cuplex Evo.

actually there are quite a number of examples of mixed metals, but they are normally plated with another metal to prevent corrosion, or anodised. even the reserator's CPU block is both alu and copper.

my main point is, those so called anti corrosive coolants will not be able to retard corrosion on bare materials in a long run.

Quick question about fans and radiator. My goal is a quiet water cooling system that can stand up to serious overclocking. Silence being the first objective. I have read the pros and cons about using the fan in a push or pull configuration. Since i want silence, i'll need a fan that offers very low db and since i want to do some serious overclocking... the fan needs to really move air.... But
I have not found any resonably priced fans that have both qualities.

So comes my question:

Use 2 fans in push and pull configuration. Does this double the rated CFM per fan. Does it also double the noise? E.g. 1 fan = 45cfm at 21db... x2 = 90cfm at 42db?

Get a bigger radiator?

Go passive, e.g. rocket from thermaltake or the reserator?

Thanks in advance

know why it's all Alu ?
coz copper rads dunt get corroded easily like Alu ones........those refridgerators rad never got leakage problem at all man.

If they don't come into contact submerged with water (which is a good carrier of ions) and there's no other materials in it's loop. Refrigerators use refrigerant gasses which are non-reactant and the exdternal part of the rad is coated in black paint to prevent bare exposure as copper does oxidise easily

this is just a part of it, like car air-cond, usualy the mechanics will not vacuum the whole cooling system before pumping in the gas, thus the moisture from air will corrode Alu.

my bro told me that his aircond factory actually purposely use metal U bend for the joints in the radiator, so it will leak at the U bend just right after the warranty period is over

the same applies to car radiators, coz they are meant to be changed.
AFAIK, for the same amount of cooling effect, fully copper rad will function better and work longer, it's so long lasting that mechanics boycott the copper rad

Has anyone tried watercooling with Eheim Canister?
It has built in reservoir and pump. Looks great.

10k L/h my god.....better change to Grundfos pumps that can pump 10psi of pressure
