What we need is something to fill the water to the saturation point, some additive, which will not affect cooling properties. Glycol seems to be a common choice, and I'm pretty sure Glycol isn't good for algae, either.
IF hte water was saturated, it woudl notbe able to pick up contaminates. Mind you, you jsut cleaned your loop out, too. If I was you, I'd swap out coolant, put in fresh water, run for a coupel fo days, then drain agian. repeat if needed.
Thoughts on that?

I've used distilled water + automotive anti-freeze (25% mix), plain distilled water, and distilled water + PT nuke (the biocide I mentioned before). I understand that an additive can increase the effectiveness of the coolant and provide a few other features like fungi/algea/etc prevention, but with kids and pets around I like the distilled water the best. I don't have to worry about having the other stuff around or keeping anyone out of it if there is a leak.

I'd have to look back at my log to see the last time I swapped the water out, but it's been a while. It's probably due for a flushing anyway. I'd really like to pop the CPU block open and clean it out, but one of the screws that holds the base on is stripped in the tools side (not the threads) and I can't take it out unless I have a replacement for it.

Isn't it?

DAve you been drinking? Seems to be some issues with your typing skillz...

I am looking into running the red motocraft for my HTPC. Very similar to dexcool.
This is my 25% Dexcool loop CPU@4ghz 1.55v
Room temp is 74F
CPU is 32C after 2 hours of crysis
OPT3 is loop temp post CPU pre rads.

Again, see my issues with this above.

Not a great deal of experience here though. I heard a lot of bad stuff about additives corroding and dyed fluids staining that I decided to go with clear distilled water.
Besides, it's a heck of a lot cheaper.  |
I agree on the dyes being bad but I have not heard much about other additives, other than residual traces left behind. I too would like to go the route of a coil, as I think it's the safest way and should not cause any corrosion due to mixed metals.

I never had the water turn brown until I used this. I'm not confident I got all of it flushed out, and I admit I may have used more than I should have. Not really clear on the directions.

Have you had experience with this too, or is this just in response to my situation?
