Made some changes to my first ever water cooled system.

I punched a 3/4 inch hole near the top back of the case and brought my intake up there to clear some space for visibility, I also changed to a 90 degree connector going to my gpu blocks. Still pumping out 1.3 gpm
Also added to sunlight bright white sticks to add some light, one stick 3 leds went bad but still plenty of light, it looks better in person in pictures it looks over bright in some parts. I also added 2 quick disconnects, makes life so much easier.

That does look much cleaner! Is that green tubing?


Not being picky, but I would move the top tube off of that power plug behind the case, just because stuff happens, ya know?

no the tubing is clear and the liquid is green. I have herd people say that the dye can cause build up in the blocks, I was thinking about changing it. koolance only warranty's their own coolant. they have a clear and a clear non conductive coolant, but it would cost me another 100 dollars to change the coolant. My reservoir for the exc-800 takes 3 liters of fluid. Im not sure if I should change or not, kind of on the fence.

Since this is my first build water cooled that is, Koolance told me If I want to change the fluid, to run warm distilled water through the lines a few times until the liquid is clear. Is that what you would recommend, how do you change your fluid?

That sounds reasonable and is common practice known as well, flushing.
I would do so with several liters of DI water.

Curious to see the other end of the system. Don't see the radiator enclosure anywhere unless I am missing it in the pictures.

Wondering what size tubing that is as well.

If you could post your whole rig so we know what you have there would be really great.

the picture is my chiller unit from Koolance. I have set the water temp to 75f, I could go lower but sometimes the dew point here gets to 70f. The chiller has 3 120mm fans all measurements for water flow,temp ect. the tubing is 3/8id 5/8od

If you don't mind me asking, what are your temps on all 3 Classies and CPU when say you're folding or benchmarking at 100% load. Ambient and water temp if you may as well.

Yeah...me too.

ok I just did a fresh test. here are the stats after a 5 min run, running prime 95 and heaven simultaneously. The reason the liquid temp rises during full stress is obvious that the chiller is trying to chill the liquid but there is so much heat, but as soon as test is over chiller drops temp back to set temp within 1 min. the highest ive seen the liquid temp get at full load when the liquid temp is set to 23.8c is 26c. Here are the results!!!

ambient at computer=26.6c
ambient at chiller in closet=31.1c
liquid temp set on chiller 23.8c
liquid temp at chiller after test=25.7c
CPU Tcase=50c
CPU highest core temp=77c
GPU1=39c
GPU2=38c
GPU3=37c
----------------------------------------------------------------------------------
temps after test
cpu=30c
gpu1=29c
gpu2and3=27c
liquid temp 23.8c

this was my gpu clocks
