one noob question, distilled water can last how long using in wc system, i mean how long need to change??? it perform better thn coolant?? but how could i spot the leak if using distilled water...

Distilled water is still the best. Coolant additives actually reduce performance. Same goes to premixed coolant solutions like PC ice etc etc.
Coolant additives are not really necessary unless you have mixed metals in your loop (aluminium + copper), or you are running into algae growth issues.

my company is selling Water Distiller. you make your own distill water. hahaha... or you can purchase from medical supplier (ME!) hehe.. it is not cheap.

if just for your computer usage, just get those branded mineral water.. it is as good as distill water. in medical field, they always do that too. just my 2 cents

not too sure about that.. i still think mineral water or ppl called RO water (Reverse Osmosis) is the best.

anyway, if u guys can look for me in puchong, i can 'make' distilled water for u guys. i got the machine in office but tell me earlier because need 3 hours to make 4 litres.

very true on that.. but the cheapest and easiest to obtain, rather than distilled water.. need machine and time consuming.

how many ppl here still have the access to school lab? hahaha... not only susah, but not practical. hehe..

the easiest is to get a water distiller. costs less than a thousand. can make water for your family to drink also.. it is the cleanest water to drink.

can u b more specific ??
noob here..
i don't get wut u mean
thank you

Not all aquarium pump can be WC pump... nirox is the most popular coz it hv better spec for Hmax an Qmax value. u also need to change inlet and outlet barbs to match ur tubing ID size. 1/2" ID is the most popular in WC setup coz it hv more choice in upgrading part. Downside by using aquarium pump as WC pump is about reliability, most aquarium pump was designed to run in submerged, so if u use it at open air or ambient temp, the operating temp will increase and this will reduce pump life time.

oh ic. ok ok. thanks

thanks for that point, to be frank, i was only thinking about the best cooling and didn't take into account of maintenance...
owe you one on this one... hehehe. thank a million man.

swiftech? i never seen swiftech in malaysia before...
is there any shops in KL / malaysia selling swiftech???

what's wrong of having dual pass then ?

the slower movement of the water within the rad would results of what ??

y go for GTX bro? everyone in xtremesystems saying that MCR-320 / 220 -QP is the next best thing after thermochill. for the price of GTX's, better buy Thermochill lah.

with rm800-1000 budget, u can build up a water cooling system (DIY) with an D-Tek Fuzion or Apogee GTX block, get 2 swiftech MCW-60 for VGA with 8800 Kit, recommend 3x120mm Radiator, Swiftech MCR-320QP recommended for budget setup, Thermochill 3x120mm radiator if got the budget, for reservoir get the EK's or Swiftech Micro Reservoir, and for the pump, u can get MCP355 with Petras Top or Swiftech MCP655(D5) will supply sufficient head pressure and flowrate, 7/16 ID or 1/2 ID tubings recommended for ur setup... dont get those thermaltake and gigabyte since u got the budget, get a decent DIY kit... u might need to mod ur stacker 830 for the setup.

Those Water Cooling DIYs stuffs are difficult to get in malaysia, u can only get it frm those US Bulk or frm Uglyvamp.

Why?
Any logical reasons?

bottom line is vinegar will destroy copper ion if u put in it too long. U will notice your copper change to blueish color.
