Hey guys,
I am hopefully going to be leak testing tonight but i dont know what to do RE coolant, i have a new 1ltr of Feser one Coolant in green but i will be using UV White tubing, obv a clear res.
Should i use this Feser one Coolant or just use pure Distilled water and nothing else?

Thanks
 
If you replace the Feser every 4-6 months it wont be a problem. If you are planning on doing a yearly flush then distilled + killcoil would be better
 
never used that killcoil, tell me more! :)
i wont use that Feser then, i dont want the green scum everywhere either
 
Its only an issue for people who let their loops stagnate for years. Ive ran both Feser and EC6 for 3 to 4 months each with no issues at all
 
Using EC6 here coming upto 10 months still as clear as the day l filled the loop, Thermochill recommend changing it every 2 years.
 
Do you really have to empty every 6 months? I have the same liquid. I though I could leave it for a year an it'd be fine!
 
If you're interested in Silver Killcoils, do your research first as these have been partially blamed for being part of the issue with galvanic erosion in EK Waterblocks.

Recommendation:
Corrosion can be avoided by the use of a low-conducting, anti-corrosion liquid (which,
in principle, is also distilled or deionized water). It is recommended to exchange the liquid
with a fresh one after a period of time to remove the possibly dissolved ions from the closed
water-cooling system. The introduction of additional metals into the system (silver, etc.) or
the use of ionic algaecides (copper sulfate, etc.) even in minor concentrations can trigger the
corrosion processes. Avoid the use of acidic substances, especially when using copper metal.

And what is your opinion? I'd be interested to hear the counter argument as I was interested in using a Killcoil myself.

People using killcoil with other manufactures products haven’t had these problems.

People using killcoil with the older blocks from EK haven’t had these problems.

Why are people suddenly getting issues from the newer blocks from EK when using a killcoil? I don’t know but must be something their end and not the killcoil.

*This is just my opinion*
 
Your opinion is appreciated.

It is interesting that they can point the finger at other things to detract from blame. I'm not an expert in the field by far, a numpty more like it, but it is offputting when you want the best for your system and you're left in doubt over someones findings.

EDIT:

It's strange that EK have halted sales of their nickel plated waterblocks. After extensive testing they must have listened to the expert report that silver coils ionise the water helping to assist in galvanic corrosion. Other manufacturers haven't yet reported issues, this doesn't mean that they don't exist just that they haven't materialised yet.

OP - I would just use Distilled, purified or De-ionised water with a corrosion inhibitor. A biocide could also be used, just ensure it's not copper sulphate based.

Halt on EK Nickel Plated blocks - 11/06/2011

Dear EK partner/user,


As EK is looking for lasting solution for nickel plating issue (concerning corrosion because of silver coils and copper sulphate additive) we decided to halt sales of nickel plated products till solution is found and tested. Our resellers were advised to halt sales too.

We cannot put users into position, that we replace products and corrosion starts again on new product. Hopefully we will find an answer and tested solution in short while.

We will update you as soon as we have any news.

However, If customer insists on buying EK nickel block, we offer a customer full 24 month warranty on material, manufacturing and corrosion.

You can use a silver kill coil, don't worry. The science of it suggests to me that corrosion shouldn't be occuring. I have a silver kill coil in my loop works fine. OP I do not recommend feser though, do yourself a favour and don't get it.
 
I had a wc loop with blue feser cooling liquid for 2 years and never changed it. It was fine and the only reason I replaced it was because I changed rads and water blocks, even then I could see nothing wrong with it.
 
I think what the test results demonstrated was that there were issues with silver coils, copper sulphate additive and nikel blocks, especially EK at the moment.

People also had the nickel problem with pre-mix fluid & plain distilled, the problem was with poor nickel plating & nothing else.

I bought an EK HF cpu block back in january, the inside nickel plating was very poor and this was just looking through the thread holes on the top of the block, i got rid of it instead of risking problems at a later date.I replaced it with a Koolance 370 cpu block, i opened it up & the inside plating was far superior to that of EK.

Also if it was silver coils & copper sulphate additives then why has he pulled all nickel plated blocks? it's just a pathetic excuse for poor plating.

Yep, the whole pulling of the nickel blocks to investigate the issue, was almost an admission as there was one genius on their forum who did a very detailed investigation of his own.

I've just built up my first WC'd i7 2600k, 12gb rig last night. It was a toss up between the clear Thermochill E6 coolant, or distilled to use in my green tubing. In the end I went for the thermochill as I am dubious about the quality of this kill coil I have. Thermochill seems to be the best coolant from reviews I've read so far. Still not convinced by dyed variants though.
