To be honest I'm just thinking out loud and there won't be answer to this.

I currently have a 4670k running at 4.4ghz with voltage at 1.275v
I have 2 x 780ti's at 1124 with a max voltage of 1.2v

EK supremecy evo, 2 x EK 780ti full blocks, 2 x D5 pumps, 1 x Havoc 480, 1 x Havoc 240 and an Alphacool 280 XT45. On the 480 I have 4 x Corsair sp120's + 3 x Artic f12's p/p, on the 240 2 x Phantek 140's and 2 x Arctic f12's p/p, on the 280 there's 2 x Noctua A14's and 2 x Phantek 140's p/p, all housed in a Phanteks Enthoo Primo V2. Air is coming in from the front and bottom of the case and exhausted out the back and top. (I've tried the 480 sucking air in with no differerence).

So what's the problem?
The water temp seems to be quite a bit higher than I expected, I know it'll be fine and nothing to worry about, but it seems high and everything feels very warm. While playing something that uses both cards like Shadow of Mordor the water temp can hit 43c. The video cards are generally 2-3 degrees higher than the water and the cpu hovers around 50-60c. But if I run something like IBT the cpu spikes to 80c but hovers in the 70's. So I know the equioment temps are okay, but the water should surely be lower with all that rad space?

The fans run at around 800rpm when gaming which is a nice volume, 1,000rpm if I have to and last night I tried full speed at around 1,500rpm which dropped the water temp to 38c, but the room temp was also dropping as it was getting late. I have a little thermometer in the room and that was reading 26c air temp when it was 43c water. I've tried the D5's at full speed and it gets noisier but no cooler. Due to a leak with a fitting that has been exchanged twice the system has been drained and filled about 5 times over the last couple of weeks, so I dont think it's an airlock. It takes about 1 3/4 litres to fill which is about right for the size.

I've thought of changing the fans but I'm not sure if that's a solution. It appears I have a very hot running cpu even after remounting it a few times and even with the new tube of IC diamond making no difference. I know the gpu's put out a lot of heat but with a 1,000mm of rad space surey the water would be lower.

It's just the fact I've seem people with less rads and similar equipment with much lower temps, I know you can't compare but I feel like I've done something fundamentally wrong even though I can't see it. Unless of course I've got a faulty water temp sensor that just reads very high. :)

Thoughts?
 
It might be a good idea to run matching fans in push pull.
Otherwise use either push or pull of thing 1 set of fans.
 
IBT, or p95 on a haswell will easily send temps into the 80's even on custom watercooling. Due to them being pasted instead of soldered, the heat gets trapped below the ihs so no amount of cooling helps if you run theese programs. Hence why you see people delidding theese chips and replacing the paste intel uses with liquid metal.

You need to make a concise version of this and use it as your sig. Would be very educational for a lot of people
 
Lol, i know what you mean mate. But it is very solid advice, intel and many board manufacturers reccomend this. Ive owned 5 intel ib and hw cpu's and all have hit extremely high temps under such applications. Im on a mission to stop people destroying their cpu's.:D
 
Thanks for the advice everyone. I removed the front part of the case over the grill and it' dropped it by a couple of degrees. AS long as the water is under 40c I'm happy. It's just a mental barrier. :)

Yeah I've read about the intel issues, but I'm not brave enough to de-lid the cpu.
 
If the rads are getting warm then that means its trying to disperse best it can, it would point towards either an airflow issue or an ambient issue. Even for a phanteks prime theres a lot of raddage in there what is your cold air feed?
 
Sounds like airflow to me too, simple way to test, take the side off your case, my case has awefull airflow because of its design, so when i take the side off my case it drops the temps by about 10 degrees and also returns to normal temps a lot faster after going back to idle.
 
Eh?

Assuming you mean where's the cold air coming in? Front grill and through the floor but these have rads obviously. I tried it with the 480 pulling air in to the case as well and there wasn't much difference.

The air coming out of the top of the case when it's running is really warm, don't really need heating in the room...! :)

I just expected it to be cooler for some reason. Last night playing Mordor the top gpu hit 48c and the cpu 60c and the water temp hovered around 40c. I just thought it would have coped a little better. Not opposed to buying new fans but I just don't want to be wasting more money as I've spent a ridiculous amount of money on it so far. It's the 3rd case I've bought in about 4 months along with Havoc rads as I wasn't completely happy with the Alphacool stuff (now have a 360 sitting in a box) maybe I'm just expecting too much.
 
Thanks Blu, but not sure how to fix it as I won't be running it with the side off. Also when when everything was pulling air in and only one exhaust, if it was airflow would it not have made a big change as all rads were then getting cold air.

I just think me and water are not made for each other, especially when the fitting leaked at the revolving bit and dripped all over the gpu....! :(
 
Yeah i didnt mean run with the side off permanently, just to test if it dropped he temps, so it would give you an idea if your air flow is been restricted.

If your happy with the speed of your fans, and your temps are ok, then i would say its all good.

The only other thing i can think of is to try turning up the pump a little, assuming your temp sensor is after your water blocks, maybe a slow flow rate is stopping temperature from equalizing around the loop. Sounds like you need a water cooling expert who knows what hes talking about instead of my guessing :)
 
your water temp does seem a bit high with your set up, you could try the rear fan as intake and exhaust the whole lot out the top thats the way mine is set up

my ambient water temp is approx 25-26 c on silent cpu i7 4930k 4.5 oc 24/7 26-32c.

a cheap idea for you is to use some free cold air as intake my last build i put an air brick in the house wall and vented it to bottom side of case where i have a 240 monsta in push/pull cost me a tenner and an hours work.luckily for me my pc is on an outside wall may not be possible for you.
i also have my 2x 980s on a seperate loop and pump mounted externally with a monsta 420 push/pull.
 
That's the problem with LC,small problems and you loosing a lot of the time on draining/refilling the loop.Touch wood pc is fine in 2015,let's hope it'll stay that way whole year.
 
This is a long shot, but noticed you had the EK supremecy evo? have you checked to see if the flow is correct? i mean the in and out port, as if its incorrect, then your flow is going to be awful? hope this helps :D
 
Thanks everyone.

I don't get it either I really don't

So full power fans yesterday 1500rpm, side of the case off, sitting in windows at idle and the water temp a whopping 31c. The CPu is throttling back correctly down to 800mhz and .7v, the gpu's throttle back as well. I guess I just have to put up with it as I can't get any more rads in there and I don't think it'd make a lot of difference if I did.

I went from a Corsair 750d with a Alphacool 360 + 280 xt to a Primo with a 480 + 240 Havoc + 280 xt45 and there's not really that much difference in temps to talk about. Just shocked it wasn't a significant change.
 
What temp is your room Supa? when mine is all idle is only a couple of degrees hotter than my room temp.

My current room temp is 19.5 degs, water temp is 21.5 degs, CPU 23, GPUs 25 and 26.

Im only using 2 rads so it doesnt really compare to your setup, but you shouldnt be needing 1500 RPM fan speed that would drive me nuts, mine are 600 rpm and when heavy gaming i sometimes turn them up a little 8-900 maybe. With all that rad space you should be able to run virtually passive :) . Did you ever get around to turning up your pump speed to see if it helps?
 
The room was a little warm maybe 25-26c which puts my delta-t at around 17c which seems much too high compared to the rad space. Flow is fine as there's 2 D5's running and plenty of movement in the res, tried both running full speed and there's little to now difference.

Watercooling isn't for me as I just don't seem to be able to get where it should be no matter how much money I throw at it. :(
 
For comparisons sake, I have a similar setup as you: [email protected], 2xgtx780 (slightly overclocked), 480+360+240+240 rads. Room temp at around 24 degrees. The idle (or web surfing in windows) temp of the water is around 27-28. (so 3-ish degrees over ambient, which seem on par)

I have at the moment all Aerocool DS fans, running at the slowest they go without stopping (like 40% power, so somewhere around 5-600rpm), pushing virtually no air at all (they are really pretty useless at that speed).
I hit around 42 degrees during heavy load, like firestrike extreme looping, due to the air inside the case is pretty much standing still. At that point my fan controller start to up the speed slightly, and the temps stabilize around 800ish rpm.

What your difference compared to others in this thread is that they have (likely), fans pulling air inside the case that is not restricted by a raidator. Have you tried placing some fans on the front side (there is two fan mounts there), or possibly in the back of the case, just to pull in more air?
