I think my loop needs cleaning

post #1 of 9
Thread Starter 
So yea I've had the loop running for what feels like a few years now. I've cleaned it once every 6 months or sooner. Cleaning as in replacing the water, checking to make sure everything's ok and re-assembling the comp in the process. I've cleaned the CPU block once. It was about 8 months ago. Found a bunch of gunk in it, was pretty gross. Also the water is kind of brown tinted.

Well a month or so ago I noticed that I needed to replace the water much more frequently. Also noticed that the reservoir's water level is clearly indicated by some type of stain on the acrylic.

I think something might be living in my loop.

The most obvious thing to do is to clean it all out.... But how do I go about cleaning a radiator and pump? I know how to clean the cpu block, and I'm going to replace the tubing.

Are there any miracle solutions or something to eradicate and protect against this type of growth?

Also... PT Nuke still where it's at? Or should I go with a silver coil this time? There's a lot of jewelry stores nearby and I'm sure one could get me some cheap silver... (read somewhere that it was cheaper than a coil)

Edit: forgot to mention that my temps have doubled since I set up the loop. Used to run at 20c, now run at 40c. Idle temps... Ofc my house was a bit colder back then but yeah.... 35c on a good day now.

Boiling water and white vinegar. Rinse it a couple times with boiling water, folllowed by white vinegar. Then some more boiling water to clean out the vinegar. PT Nuke works, but a lot of people prefer silver coils.

I'd just say go with a silver coil, its the best bet.

Ambient temps affect loop temps quite drastically. Careful with how much white vinegar you use...never use more than 10% solution (or 1/2 cup vinegar to 4-1/2 cups water) as too strong a concentration of vinegar can easily damage copper.

I use PT. Nuke. The bottle is a few years old. Would the PT Nuke being old cause this problem?

The sulfates in PT Nuke could be causing this or maybe the plasticizers from the tubing. I would switch to a silver coil to see if conditions improve since it contains 99.9% silver in comparison to PT Nuke which is only 25% copper (sulfates and water make up the remaining 75%).

Either way, a dilute solution of vinegar should clear up all your blocks and radiator.

Boil the fittings and reservoir into oblivion.
For the radiator; fill it with alcohol and shake the crap out of it.
For the waterblock(s) use alcohol and a toothbrush.
Change your tubing.
