Hi All!
 
 
I am hoping to rebuild my w/cing loop after a tragic incident involving plasticizers. Well not tragic but I noticed my loop was clogged and I use distilled water and a kill coil. I built this loop 5 years ago before I knew plasticizers were even a thing. Anyhow I want to rebuild my loop for my new rig.
 
I currently have a h75 on a 6600k which is doing well (had to buy something to replace my loop). I want to put that setup into a build for my fiance so that means I need to use my old loop to cool my new 7700k and my 1080ti.
 
I plan on delidding my 7700k (not sure if I, personally, should do it or not). I then have my old ek waterblock from my original sandy bridge build that still works if I buy the updated backplate. I'm thinking this should be fine as waterblock design should have changed THAT much that I'll have hugely different temps by getting a more up-to-date block.
 
I'd like to use EK's gpu waterblock as it is 129.99 either in black or clear (any reviews?).
 
I'm hoping to tie this all into one loop. My pump should be plenty strong although old (all of these parts are from my 5 year old loop). I have a super thick xspc 360 rad that I used 3, 1850 gentle typhoons in a pull setup. And I will be getting a dual bay res with flow indicator from EK because my old res isn't going to fit anymore.
 
I'm wondering if the 360 rad with 3 fans will be enough to cool and OC'd 7700k and a 1080ti. Should I do push/pull? Two rads? Two different sizes?
 
Thinking: Res>Pump>CPU>Rad>GPU>Res/repeat
 
I'm looking for any suggestions or tips for this. I only want to build this loop once. I'll be getting higher quality hose this time but I always use distilled water and a kill coil and compression fittings. So I certainly strive for quality and reliability.
 
Thanks gents! Look forward to hearing your input!

Only have one Rad so far though, are you suggesting to grab another rad? Or for single would you suggest: res-pump-rad-cpu-gpu-res/repeat?
 
 
Definitely will post photos, may not be for a month or so though while I acquire everything :)
 
Another question for those of you reading the thread, how should I clean all the gunk out of my old radiator, waterblock, fittings and pump?
 
 

One rad would work for both that cpu and gpu, but for better temps you can add another rad....as Maxfly said stick with a biocide and distilled. 
On a side note, I keep a spare D5 pump handy as a backup as I had mine die abruptly after 5+ years. To me it's worth it to have a spare but your mileage may vary ;) 

Hmm, silver and EK blocks having problems you say...maybe that's why I had flakey chunks in my loop and not due to plasticizers. 
 
Anyhow! I do have the rx360 rad, a classic. Has some bent fins I'll have to fix but works great. Also can't remember the pump name but it has the xspc acrylic top on it.
 
Due to the design of my case I kind of have to use a push setup on my rad. The main intake on my case is from the bottom where there's space for 6 fans or two 360 rads. I'm just wondering if I will need 3 extra fans to also pull on the radiator. Not sure how much heat a max OC for both a 7700k and 1080ti is gonna make. 
 
Amazing to know one rad can do it, very happy! Crazy about the kill coil stuff, always liked the science behind it. Back to PT Nuke I guess. Now does that biocide have to be reapplied? 
 
Thanks everyone for the responses :D

Alrighty so it seems the primochill hose comes as a retail package with all of that stuff, so I will go with that! As for my loop I'm trying to visualize what will work best. I have the mcp355 which I will be installing in an xspc dual bay res. So I'm thinking my best loop would be Res>Pump>GPU>Rad>CPU>Res I assume that will be fine. we are going for path of least hose, tight bends and most assistance from gravity.
 

i would go res>pump>cpu>gpu>rad>res. your pump uses the liquid to cool it's self also so sticking warmer liquid in it may shorten the life. also the kill coils are only good for a year or two, usually they will change color. 
as for coolant, you want to change it about once a year, the biocide will breakdown over time so a drain and flush with new will keep everything happy. i use EK cryofuel with distilled water and it holds up great i also use DP ultra premix from aquacommputer in another system (with a aluminum rad and copper block) and it works great with no corrosion or discoloring at all.

I shall see if I can make it work with the rad at the end. I certainly don't fold but I do game for a few hours. My room is also pretty chilly, good ambient temps.

Just to be clear
 
Some posts in the many different forums around the web had issues (if I remember correctly about 2 yr ago, lol)
 
I would avoid older LTR, especially if it was bought from a "bulk reel" and Not "retail Boxed LTR with the system prep included"
 
You could always ask Primochill, to check their records and see if your product has any complaints or ask to exchange the material you have
 

 What about corrosion protection ?

Good luck

So today I got all of my supplies in and will be cleaning all my fittings, radiator and pump. I plan on using vinegar to clean my old components as they have plasticizer all over them. I'm not sure if I want to use the sys-prep or not....not too many reviews, positive or negative on it.
 
My question is, many of my fittings (bitspower) are 5-7 years old. Do I just need to remove and clean the old o-rings or do they need to be replaced?
 
Also is there an easy way to tell if my pump/bay res has any leaks before running the watercooling system? It seems these bay reservoirs can be prone to leaks? I have the XSPC Single Liang DDC (I'm using the swiftech mcp355) dual bay res.

If it was me, I'd replace all of the O-rings on the fittings. I've had some that were 2-3 years old and caused leaks and pretty substantial ones too; when they go they go completely and you don't want any surprises after you put it all together. As for the the Sys-prep? IDK I don't see how it could hurt.

I will note that evga has labels on their blackplate and card which state that upon removal the warranty is void. This is confusing since I thought evga doesn't void warranties for removing coolers.
 

 
You might be talking about the sticker with the Serial number on it? removing that will void warranty as such it could be that someone might try to switch a serial # on a card.

Loop is all assembled. So far so good in terms of leaks, now for my temps I was hoping for a little insight.

When I used to run just my 6600k on a loop with a swiftech microres, xspc top on my mcp355 but same thick as heck xspc360 rad my temps were around 19-23 at idle and maybe 35-41 underload in battlefield 1, supersampled max settings all that. Probably my most demanding game?

Now with the current setup on a 7700k and a 1080ti Fe in the loop with a bayres directly hooked to my pump and the same rad, I'm seeing 68-70 for the cpu and it's only at 50% ish usage (afterburner). 

My gpu is at about 50% usage at 50c.

Are these somewhat normal temps for a single 360 rad loop? I feel like the cpu is too hot and I would never be able to OC on this loop :/
 
Edit: worth noting I have this 7700k delidded. I ran Prime65 for about 2-3 minutes at Small FFTs and hit 70-71 on my hottest core.

 
I would try reseating the block and also make sure there are no air still stuck in the  lines/block (running with a jumped PSU for ~12 hours, filling water as needed into the res). I've ran my 6700K with 2 x 1080 Ti FTW3 on a 420/3x140mm rad and not have my CPU reach higher than mid 60s @ 100%.

I realized my fans were in backwards. Instead of pushing fresh air through the thick 360 rad, it was pulling the warmed air in the case, through and out the side....much less efficient. I'm hoping this solves much of my issues.

Let's hope so; I did that once too and couldn't understand why the temps were so bad until I turned them around lol.
