Dowfrost – Cheap!

tehfrr · 08-01-06, 08:09 PM

I found somewhere to get in gallon amounts, and CHEAP. You can have this stuff for $17.93 per gallon! After shipping and whatnot it came out to $36.49 for me. That means you get 2 gallons of heat exchange fluid, as you have to mix it with distilled water.

Sub Total: $17.93
Taxes: $0.00
Ground Shipping: $15.06
Handling Charge: $3.50
Total: $36.49

What is dowfrost?

tehfrr · 08-01-06, 09:18 PM

Its a heat transfer fluid based on propylene glycol. Its colorless and water soluble. According to another user on this forum (phaeton) its non-conductive too. Im interested in using it as a fluid I do not have to change/maintain. I have a gallon on order, I am going to try and dye it with FrozenCPU blue UV dye before I put it in my comp. Ill post a pic of it after I try that out if anyone is interested.

You are worried about what the silicates will do to your loop yet you are willing to put UV dye in it.

phaeton · 08-01-06, 09:43 PM

Woah man that is cheap. The industrial source for the shop that I get it from is running 85$ a gallon...

tehfrr · 08-01-06, 09:58 PM

the dye looked like an aqueous solution. Are you saying it is more of a colloid (particles in suspension)?

There is no such thing as a fluid you don't have to change. The anticorrosives will deplete over time no matter what you use.

The dye is water soluable. The point I think SiGfever was trying to make is that it seems kind of counterproductive to go through the trouble of getting this stuff that is supposed to be so wonderful and non-conductive and add dye to it which may or may not make it conductive.

tehfrr · 08-02-06, 12:16 AM

ahh. I dont really care about the non-conductive part really it just seemed like an added bonus to me. I am more interested in a system I will never have to drain/refill until I upgrade again, and have it look nice and clean the whole time.

voigts · 08-02-06, 12:19 AM

I have read threads of people who in a same metal loop kept their coolant for like a year between flushes, but at some point, you are still going to have to flush and refill. If you use a drain valve, flushing and refilling is no big deal.

Zx2Slow · 08-02-06, 08:56 AM

So you add distilled h2o, or do you run 100% dowfrost?

tehfrr · 08-02-06, 09:14 AM

you mix them. of the 2 people Ive seen that use this, one uses 50/50 and the other uses 40/60

I ran my MC5000W for 2 years without changing the fluid, RO water + Dowfrost...

When I finally drained it to upgrade, it was like I put it in the first place. Upon further inspection of the block it was nice and clean.

What is RO water?

clocker2 · 08-03-06, 05:52 AM

Water from Romania?
