Best Coolant to buy

Coolants don't really affect your temps. It's more there to keep your loop clean from algae and corrosion. The rule of thumb is 95% distilled water and 5% additive/coolant. You could use Zerex or car coolant for the 5%.

I'm really happy with Danger Den MCT-5. Supposedly you can get about 1C lower with it, but I don't know. I bought it because it doesn’t conduct electricity. I had a little spill when I was filling my res and I coated everything and nothing fried.

Well yeah non-conductivity is a must...I was always leary about WC for leakage reason.

I really just seeing if there was anything out there that was of a better formula that rendered a lower temperature kind of like Freon does..I know there's more that goes into just using the Freon to get cooler temps but I wasnt sure

Well I saw something on some review site about MCT-5 cooling better then water, but you never know with half of the review sites out there. Most of them just get way too giddy that companies send them free stuff and that can cause a biased review.

I've actually heard the opposite, that while it's non-conductive the trade-off is like 1-3C increase in temps.

I'll take the 1-3C increase if it saves my computer on a major leak, if it happens..all it is is Deionized water

Well there is THIS found at madshrimps

Hey Guys,

I`m in the heat and air business, and I`m curious if there has been some sort of refrigerated cooling offered. It could eliminate the worry of leaks and a lot of tubing, although some engineering would have to be employed to regulate the cooling load factors that would make condensate production a factor.

When you say refigerated cooling, do you mean something like a water chiller? Or something like a phase change cooler?

Most if not all cooling experiments you can think of have been attempted, and the working methods have made it into aftermarket products.

I`m talking about a direct expansion method, whereby the heat sink is made into an evaporator which has refrigerant pumped into it via an expansion or metering device. This could conceivably have a discharge air temp. of as low as -20 F, but it would have to be higher to prevent condensation issues. The other side of that would be getting rid of possible condensate from the heat sink/evaporator.

That would be a "phase change" unit, and many of them exist. Chilly1 has custom units, Vapochill is another, and also Prometia.

Many of these units see temps of -20 to -30 degC (and some even colder) during load.

Thanks Xavier1421 for your info. Also, you`re the first reply I`ve received on this site since I joined 2 days ago.

Xavier1421,

I`ve left several other posts which have yet to be answered. Could you possibly check them out and let me know any of the answers? I`d so greatly appreciate it.

i did some experimenting myself, reguardless water is the best cooling medium still. If you want to do it right, buy a res and custimize it to where you can run a coil through it (water chiller) and use water with some additives. You shouldnt be worried about leakage, if you put the water kit together correctly. You have the same mobo as me, you need a chipset waterblock if your going to overclock.

I am using the coolant that came with the big water...(thermaltake), withouth water... it says"Coolant may operate withouth extra liquid" so i just put it... and no water.... Should i have put water to have better temps??
