Fixing a Leaky AIO Liquid Cooler, Then Using Toothpaste For Thermal Paste

[judahg460]

Thanks. Yeah i have changed some things since i first posted, but all's well. I am a little worried about the toothpaste though. I have changed it out about 3 or 4 times but I'm going to order some arctic silver 5

Did you use a biocide? Otherwise, even with the closed top, you're going to run into algae and bacteria issues fairly quickly.

I always wondered why closed loops cooling system in computer did not simply use a glycol based mix for the lliquid? car have been using it for decades without issues... 60 water 40 prestone ?

I wish we could have super duper hardware that didn't get very hot but was AWESOME, you know, like the Holodeck kind of stuff

judahg460 - Did you ever consider an external feature to your loop that incorporated a peltier plate? I purchased a 12v peltier and played a little with it but because it cooled to below freezing it frosted up with condensation. Dangerous in a closed case. I have an open-air PC (no case but rather a test bed) and it cooled the cpu to a surprising extent.

Most AIOs use a glycol mix for their coolants, primarily because the copper base plate and aluminum radiator would be conductive and corrosive with one another.

Well what house hold thing could i add to the loop that wont damage it but will kill the bacteria and mold?

You could go with a 25-40% automotive coolant to water mixture if you wanted. Otherwise, you can find antimicrobial/anti-fungus growth drops for fish tanks and other things at most retailers that carry pet supplies.

I do commend you for your DIY approach, though. You're on your way to really getting into custom watercooling, which...you've already taken the first steps on what you need to consider for each component need.

Thanks

Syringe some of my distilled water out of the resovoir and then replace it with anti freeze?

 

[judahg460]

ok well i emptied half the resovoir and filled it back up with antifreeze

Ok now with arctic silver 5 it is 142 after 10 minutes in prime 95
