After yesterday's post I took my CPU block down again and cleaned it with the tenacity of a mad man!! Back up and running over 7hrs I still have a tiny bubble, which is A LOT better than the entire top of my block holding a bubble!!! The flow through the block is much improved from what I can see. If I cycle the pumps the bubble will pass through and then come back a lot later, which is an improvement also. My question: Is there a better brush I can use to clean the fins on this block? I used a tooth brush and a vinegar soak. Could I use a copper bristle brush perhaps? It feels like I am just polishing the block instead of cleaning it. Thoughts?...

It lives!

After 15hrs+ of operation, to my utter disappointment the bubble has returned.



I restored the CPU block to damn near stock, checked the plexi for any imperfections. I mean, this thing almost looked the way it did when I pulled it out the box initially. I don't know what else to do.

I welcome any ideas as I am under the impression I have exhausted all solutions sans purchasing a replacement.

HELP!!!

Well I'm no expert but if that crap hose did that to your cpu block could other blocks not also be effected? Perhaps the cpu block is merely where it (ie the bubble) is getting stuck?

What other blocks do you have?

Have you contacted the block's manufacturer about this?

The only other thing I can think of is to try using a bright dye in your coolant and see if you have a micro leak somewhere. I.e. a leak whereby a couple of drops of liquid are essentially resealing the leak.

I was also thinking along those lines. I have a Bitspower Memory Block. That one is acrylic and I can't see any blockage. Also, I have two Heatkiller GPU-X3 HD 79X0 blocks. Possibly those could be in as poor condition as my CPU block was. However I have two MCP655s with the Bitspower dual pump top and I doubt bubbles forming in the GPUs would be able to fight the flow back to the CPU. My CPU block is before my GPUs. I have watched the system closely when cycling the pumps and I've never seen any bubbles travel from the GPUs back to the CPU.

At this point I have not. However, that might change very soon if I clean my GPUs and this annoyance continues.



Thanks for the help gang. Wednesday I'm going to clean my GPU blocks [if needed]. Also I am going to run my loop with the CPU block exclusively to eliminate other blocks contributing to the bubble. If the bubble appears from that test, I will have to contact EKWB for hopefully on overlooked solution and | or replacement.

Stay tuned...

If it's advanced LRT, you can relax. If it's PRO LRT there are very good odds you will get plasticizer in your loop. They had some real horrendous batches of PRO LRT before they released the advanced. Still got 15 feet, completely useless.

I just feel like there is something restricting your flow, otherwise the average pump would push that bubble out.

On a side not. Fantastic job on the cpu block cleaning. I never managed to get it that clean!

Could your GPU blocks also be block? What is the rest of your loop like?
Could it be that you have many 90degree fittings etc and restrict your loops flow.

Where does the water flow to from your CPU block? maybe there is some restriction after the cpu so the water gets to the block but then hits a wall so to speak.

edit** just went back and looked at your pics. Are you 100% sure mem block is gunk free?

Alternatively I would contact EK and ask for advice from them.

I count 12 90 degree fittings out of the bunch. If it's slowing my flow I can't see it with the naked eye. The return to the res is visibly turbulent if my 150 is less than half full. When I am refilling the loop my res empties in 1 sec or less. Also, I previously mentioned in an early spot I rerouted the loop so that the CPU block was first after the pumps to eliminate fitting restriction as an issue. In that config I received the sinister bubble also. However, since cleaning my CPU the bubble has not grown as it did before. Prior to cleaning I would bleed the system, tilt the build to pass the bubble, and over the next couple of hours the bubble would grow so that the top portion of the CPU block would be bubbled. I could see the copper plate while the system was running!! As I write this the bubble has not increased. Funny thing is I've seen smaller bubbles get pushed around the sinister bubble during refilling and pump cycling - weird?

Pics of my current loop:
the beginning...

...the first 2 480s...

...the 3rd 480. The acrylic goes to the CPU block IN


The Loop:
150 Res - Dual Pump top MCP655 - 480 rad - 480 rad - 480 rad - CPU block - Mem Block - GPU block - GPU block - 150 Res

It's going to suck balls if cleaning my GPU blocks do not pop the bubble.

*NOTE*
My coolant is off-colored 'cuz I'm running out of Mayhems Pastel White and adding distilled water 'til I place another order
