I recently finished building my first watercooling build for my gpu and i see that it has this slight grime or this cloudy buildup on the inside of the plastic area. I was wondering if there is any way to clean this out. I also see some little fuzzy particles around the micro fins, is there any way to get those out of the system?

How long has it been since you did maintenance, usually you want to change fluid every 6-12 months and open for cleaning if there is any build up.

 

Some minor build up or coating of surfaces can occur so you will need to take apart the GPU block and open it for cleaning, before properly reassembling it.

Depending on what it is, you might be able to pick up a Mayhems Blitz kit and clean that out. If it is something more grimy, then you might have to actually disassemble the block and get to cleaning with a tooth brush and some toothpaste or whatever the kids use now a days. 

 

If it isn't affecting your cooling, you shouldn't have to worry too much about it, just might look a llittle unsightly. I'm currently putting off a tear down of my build for something similar in my GPU block. But my difference is I am using pastel fluid and that's just the nature of the beast.

Was the components mainly the rads properly flushed before assembly? 

 

It may have been something also during manufacturing when they assembled the block leaving a film on some surfaces. What are your watercooling loop components?

I didnt use any system prep, i probably should have. I used a bykski 120mm rad, bits power fittings, ek petg tubing, a new distro plate from ebay and corsairs xg7. If all else fails i can just take the block apart and clean it which i might end up doing

I'm guessing it's probably some flux or debris from the rads mainly that came out, it's always best to flush and rinse the rads before assembly. I usually recommend to fill them around 50% with just tap water to vigorously shake and rinse, to do that about a half dozen times before giving it a final wash with distilled water. 

 

It's probably alright for the time being and you can let it be until the next maintenance cycle just keep and eye on temps to ensure it's not building up.

Assuming I have the flow direction correct, that buildup I circled could be restricting flow.

It's probably alright for the time being and you can let it be until the next maintenance cycle just keep and eye on temps to ensure it's not building up. 

And even at that you'll still need to probably do a cleanout of the loop after a while and still find build up...radiators are just nasty and should really always have a filter put on the outlet of them (and even at that you'll still get "fogging" from shit that the mesh won't catch).  I've had max-hot water from my tap circulating full blast through a radiator (my faucets are hipster-design 1/2" diameter pipe so it couples nicely) for 30 minutes and still get shit in the loop.

 

But really it's cosmetic...the performance of the block in OP doesn't look like it's going to be significantly affected.  Right side of the fin structure looks a little grody though.
