Hey all,

I have read a ton of posts on this forum and others about all the different options for coolants to use in Water Cooling Systems.

Got a few questions about mixing my own coolant though:

I got the Thermaltake Bigwater SE system and was running with the Coolant that Thermaltake provided. Just upgraded my PC to:

Asus P5N32-SLI Deluxe
Intel Pentium D 805

Anyway, I am thinking of making my own coolant cause the Thermaltake one looks used and ****ty.

How does this sound:

95% Distilled Water (From local gas-station, Canadian Tire)
5% Valvoline Zerex Super Coolant
(Possibly some UV Dye)

Can i just buy the Zerex Coolant they got @ Canadian Tire or other auto-shops or does it differ from the 4oz and 8oz bottles available online?

Also, what are the opinions on adding UV dye to the system? From what i gather, there is no noticable effect on the temperatures...

If anyone has any other suggestions, please let me know. Thanks.

UV dye has no effect on temps
yes that will be same as buying online
good mix, is the super coolant have ethyl alcohol in it that is ideal

95/5?

Uh...is it different than from cars? Cause as far as I know cars mix 50/50 with distilled water. Is it just less because the heat factor is so much lower?

Sideburns,

for pc's you need 20:1 ratio .....or there abouts...so basically 95/5

Sideburns

Hmmm..well I get that.

But why exactly? Better heat transfer? I'm not so hot with coolants (pun intended)

The only reason you add something to the water is to prevent corrosion or you want to change the color. I get the same temps with straight distilled as I do with distilled plus Cosworth. The Cosworth just looks great and prevents corrosion in the system.

but with liquids that have higher spH than water, it will make a difference
google: specific heat

In cars you need 50/50 for optimal overheat and freezing . I have a friend who uses Redline waterwetter added to distilled water in his PC. We use it all the time for drag racing drops temps down about 10C in drag cars, you can get it at Canadian Tire or speed shops .

No, I am not talking textbook formulas and such. I am talking practical application. I know what I have personally seen. That is that most stuff that is commonly used in WC setups makes little or no difference in your temps. 1 or 2°C is within the margin of error and I do not count that. The most important reason to run an additive is to control corrosion.

Renegade5399 why do you choose Cosworth Coolant over Zerex or WaterWetter??

Is it just cause of the looks or does it have better properties? And do you still use the 20:1 ratio?
