Corrosion

omgitsdavie · 5 Sep 2015 at 15:26

Hi guys, ive just torn down my old rig to re use a rad and cpu/gpu blocks in a new build. Ive notied a fair size build up of these turquoise flakes on the bends in the tubing which im goin to assume is corrosion.

Ive ran mayhems blitz p1 through the rad but that wasnt too mucky when i emptied it. Should i pick up the pro kit and trust that will sort it? Or should i crack open yhe blocks for inspection?

I would personally open the blocks as the tiny heat sink bits maybe cloged up and require as scrub. What coolant were you running?

You really need to strip all the blocks down as it will be jammed between all the pins/fins. If it is corrosion then you need to make sure you get it out of the rad or you will have the same problem when you get up and running again. If it's the rad that is corroding then it's highly unlikely that you will get it all and it maybe a better idea to buy a new one.

One of my mates had a similar problem. He asked me to take a look at his pc as his temps were climbing and he noticed bits going around in his loop. I stripped it all down and his blocks were almost completely clogged with blue-green gunk. It was even in the pump!! One of his rads, a Thermochill PA 120.3 was pretty badly corroded inside probably due to the fact he bought a crappy cheap 120mm rad on Ebay for extra cooling which turned out to be aluminium and he used de-ionised water with no additive!! We tried the full Mayhems Blitz kit on it but it did very little (to be fair it's not for removing corrosion). In the end he had to throw the PA120.3 in the bin and buy a new rad. He has also been educated on what liquids/additives to use and not to mix metals.

De-ionised water+Mayhems X1 - Clear Concentrate[anti-corrosion, scale and biological fouling]

Use it myself.

Well the blocks were opened up, but were surprisingly clear, but not spotless. Ive given them a clean out anyway and reassembled. Ran the blitz part 1 through the rads and part 2 through the whole loop and flushed 3 times with Di water. Noticed a lot more debris being flushed out once the part 2 had gone round i have to say.

As for coolant, im not 100% This is the first loop ive built myself so once id finished i took it to a mate of a mate who "knows what hes doing". He filled the loop there. At the time i didn't really know a huge amount about coolants so i just assumed he knew what was best.

Needless to say lessons have been learned :rolleyes:
