Hey,
I'm running a simple setup (XPSC Pump/Rad combo) hooked up to a EK 360 rad, an i7 block (EK Acrylic/Nickel) and an EK 5850 Block (Acetal/Nickel).
I'm currently in the process of flushing out the old FluidXP to change it with some new EC6 stuff, and noticed lots of green crap clogging up the CPU block where the fins are. Now naturally i'm slowly getting some out (or so it seems) as i am currently running de-ionised water through it and have flushed this about 4 times so far and got some bits out, and just wondered of the best way to get the rest out?
I don't particularly want to open up the block as i'm scared ill muck something up, so any advice is appreciated!
Currently i'm running the CPU and Rad in the loop only at the moment in the hope that the pressure will push any of the gunk out of the CPU block, perhaps i could also remove the rad from the loop also? How about if i run the loop backwards so it pushes the gunk back through the way it came, would that help at all?

All of this is being done outside of my desktop so safety is fine, and nothing needs to be cooled so any suggestions welcome - and a bit of advice to anyone, don't bother with the Dye it's not worth it!!
 
Use ketchup and vinegar, works like a charm :)

I may have missed this, but have you taken the top off?
 
ketchup and vinegar really? how much do i add (my loop can contain 1L of water)? i'll assume vinegar is the better source due to it being thinner!

i haven't taken the top off no, and i want to do anything possible without taking it off :)

also what type of vinegar, white vinegar i guess?

Dismantle your loop and hook the cpu block up to a household tap. It's easier than trying to flush it out and much less risk of moving the cloggules into your rad!
 
An, I would only recommend ketchup if you had taken the top off. Vinegar is your best bet, wash it through a few times then hook it up to a cold tap as above :)
 
Just dismantle your block. It's very simple to do, just a few bolts and you will be able to clean out the block properly. When putting it back together, just make sure the little rubber seal is in its groove all the way around and bolt it back together.
 
i'll give it a go first, seems liek the best way, i have distilled vinegar on hand also now!
i wonder what the gpu block is like, temps ahve been fine for it so i assume it is "ok", but it has a "void" sticker on it so can't take that one apart!
 
hah well i couldnt agree anymore, but when i'm not confident in it i'm not going to void it :)

had the cpu cover off, got rid of the gunk!
do you think it's still worth running some vinegar in the loop to make sure any in the rad/gpu is gone also? and is it safe using the pump with the vinegar or am i meant to run it using mavity?

cheers

What you need to do is take the loop apart, strip the blocks down and flush the rad out properly. If the CPU block was gunked up then the GPU one is likley to be similar.

Next thing would be to listen to what a lot of us have been saying for a long time. Use de-ionised/distilled water with a kill coil or additive and if you want colour just use coloured tubing.
 
that's exactly what i've done, gone for the simple ThermoChill EC6 with no colouring and white tubing :)

I've stripped & flushed out the cpu, and i flushed out the whole loop 8 times and 2 times with vinegar so it should be "ok", not perfect but i'd rather not void the warranty so it's good enough for me!

Just finished it now, all backup and running, temps have dropped ~10-15c all over!
I've also switched from EK's own thermal paste on the CPU to the IC Diamond stuff so that should help too!
 
you should definitely dismantle the loop because you will probably need to flush the radiator with vinegar too cuz that XP crap seems to stick to everything.

just go out and buy a big bottle of white vinegar, fill up the rad and leave for an hour or two, drain and repeat until the vinegar comes out clean.
