I recently got a pair of EVGA 3g GTX 580's and EK water blocks. The are replacing 3x GTX470's and Koolance water blocks.
My problem started with the 470's and the Koolance blocks (I have a previous thread). The flow was seeming to get restricted and my flow meter would seem to "stick". I would give it a tap and it would start spinning. My flow was about 4.9 - 5.2lpm. I could feel the preasure building before the blocks and the lack of preasure after the blocks, which is where my flow meter is (Koolance FM17). note: My original loop had just 2 blocks and a XSPC 240 Rad and the problem started when I added a third block and swapped the 240 for a 360 Rad.
I opened up my blocks a couple of times and had to clean trash from the first block. I also emptied and flushed the Rad the first time this happened, and yes I cleaned it with hot water during the initial installation, but the problem persisted.
Now I have replaced the 3x GTX470's with 2x GTX580's and EK EN Nickel Acetal Blocks with back plates and a FC Parallel Bridge. My flow started at about 7.2lpm and then dropped to 4.9 -5.2lpm after about a day.
Also I drained the loop about a week ago when I removed the 470's and installed the 580's to run them before installing the blocks. I connected the hoses but didn't put water in, I just disconnected the pump.
What's the best way to fully flush and clean my loop and would a filter help or would it be too restrictive(koolance makes one)?
Any ideas on where the trash is coming from? I appears to be the same color as my tubing which is Red Primochil 1/2".
One more note: my temps don't seem to be noticably affected.
Loop contains: XSPC Dual bay Res w/pumps, Liang DDC 3.25, XSPC 360 Rad, 2x EK FC Water blocks
