So after having the system cleaned and changed out 9 months ago with new tubing and coolant including gpu and cpu block pulled part and cleaned. Yesterday when i turned my pc on i noticed my pump was sounding odd and as i noticed this the entire res went white.

I thought micro bubbles but it settled down so turned my pc off. Went ahead to clean the system and the gpu, cpu and rads were blocked and one tube length was completely cloudly. I suspect plasticiser.

After a full clean i went ahead and used my new zmt tubing (was planning to use it soon anyway) and filled my res up and same issue again. After yet another teardown i would seem my rads are both clogged just from boot. Tried to clean the rads but could get the clogged out for some reason.

No worries new rads it is. Corsair XR5 240mm and 360mm was my choice. Cheaper than most and my previous ek se classics are pretty poor rads. Would have put pics up but in my panic to clean my system and get it up and running i forgot them but i will upload my system before.

The tube from my gpu to my 240 rad was almost opaque and was thick with plasticiser. Never seen it this bad from a single tube no more than 9 months old. Pics with teardown and reassembly coming tomorrow

So silly me forgot to take photos of the assembly yet again :rolleyes:. However the new rads are working a treat, helped by re-paste of thermal paste on gpu and cpu using less efficient coolermaster ic essential e1 over arctic mx-4. Using port royal and cinebench r23 at the same time for the 30 minutes as i always do for heat soaking. I got very impressive results over my last setup.

Old Setup:
Ambient: 20.5c
CPU: 71c
GPU: 51.8c Hotspot: 69.4c
Water Temp: 32.5c

New Setup:
Ambient: 20.5c
CPU: 69c
GPU: 45.3c Hotspot: 62.4c
Water Temp: 31.7c

Last batch of Mayhems that I used, tainted very fast using their own fluid.
Used Ek and was fine.
Ditched all and went with ZMT.
 
If you go for ZMT in the future make sure to clean it out. I made the mistake of not cleaning one batch and it left this weird residue all over the place. It looked like growth but it was just something off the ZMT itself. It can be grimy on the inside. Though I was / am using Tygon tubing not something from EK.

I was informed of the residue that maybe in the tubing and did clean all 3 metres with distilled water 3 times. still got a bit of residue in the loop but all good now.

Same here. Floating black dust on solid white. Also slightly blocked the block's fins.

Been on ZMT for 5 yrs without issues.

With the same tubing?

Yes.

Cleaned rads, tubes, fittings & blocks prior to first build of loop. First washed with tap water, then final rinse with distilled water.

Originally built loop in 2017, initially Threadripper 1950X with MSI GTX 1080 Seahawk EK. Later swapped GPU to RX VEGA 64 with EK block. Further down the line swapped EK TR block for Bykski TR block. Then swapped to R9 3900X, using same Bykski TR block as it also supported AM4. Few months ago R9 5900X with RX 6800 XT with Bykski block.

Below spoiler has photo of res taken on 13/12/21, the coolant has been in use since 2017. Distilled water with 20% mix of Mayhems XT-1 clear concentrate. Each time I changed hardware, drained coolant looked clean and decent, so I reused it.

On drain down when changing HW, I've once or twice wiped inside of res, as noted some minuscule translucent film like residue.

Again on drain down to change HW, once opened CPU block to clean fins, as noted ever so minute black particles. Which I couldn't see when loop was filled/in use, in my books my loop has been zero maintenance.
