EK-Predator 240 QDC results with GPU QDC - Page 3

post #21 of 44
Thread Starter 
Good questions xtremelauke , and I must say at the moment I am very impressed, i will take screenshots to validate, but I'm finding basically low to mid 50c / 60c on both GPU and CPU respectively...I've run a few soak tests where I've left Aida64 running for cpl hours stressing both CPU and GPU, then running Unigine Valley I find 2126mhz on GPU at 53c and 45-50c on CPU.

Now I know these arent great water cool temps, but using only the 240 CPU QDC I'm impressed biggrin.gif

In terms of RPM of fans its running off the CPU header PWM and fan RPM barely goes to 1000-1100 under load smile.gif so if you know the vardar fans you will know this is quiet.

The chassis fans are at 40% and I have to say col air blows through this case.

I dont have a db meter but the rig sits right next to me, and idle browsing I barely hear the pump, gaming, I dont hear anything bar the game sound.

I'm happy now as I feel this set up will easily manage an upgrade to Z270 and i7 Kaby lake in Q117

I will post some bench marks and temps over the next week or so on this thread

Thanks for your interest...

I will eventually custom WC this rig...I just aint really grown a pair yet (https://youtu.be/67glAjdvwLc?t=55), however it was my following of #jayztwocents that I found out not only about EK (erm, corsair AIO owner originally, shh wink.gif na they are good! I just wanted more) ....but following his channel got me into learning about waht EK have done with the predator format

I am surprised your results are that good. I don't know how quiet the Vardar fans are while on a radiator (as fans on radiator always make more noise, especially when they're thicker) but I understand it's quiet. I've got really good air cooling going on without anything that I can hear in idle (as there is no pump and the fans are either off or running at +/- 400 RPM) and during gaming I can also barely hear a thing, but I have to admit I am slightly jealous as this does seem like a very well matched set up that allows you to go even more silent at load or overclock a bit because an additional 20 degrees would be perfectly fine.

That does bring me to the question: did you run these benchmarks both at once? Because this is a more realistic scenario in the sense that you're stressing both components at once and thus really push the EK Predator 240 in the two-component-liquid-cooling-set-up. Of course it's not realistic in the sense that both components are under full load. This helps us to put these results in the right perspective. And maybe if you feel like sometime, you could even try running both components under load in a follow-up test until temperatures stabilize. Stabilization takes a considerable with liquid cooling, I understand, as the water can absorb so much more heat. Either way, thanks for sharing your results and build already.

Jay is great, I've started to really like his videos. And yes, I should grow a pair too but I also preferred the EK Predator to a Customer cooling kit (for example EK's). But I went for a Palit GTX 1080 with a huge air cooler very recently after I discovered that the EK Predator 360 didn't fit in my case, was disappointed with this and thought the EK Predator 240 wouldn't be enough to cool my 6700K and GTX1080.But honestly, if this setup works this well, how much more is there to gain more expensive custom loop that will give you more hassle, apart from being a cool hobby project? Maybe in case you have a case window like yours and care much about the aesthetic advantages, I really think that becomes even more so the main argument with these efficient components like the GTX10X0 series or Kaby Lakes.

Here is a pic after running trial version of aida64 for about 15-20mins or so

Very good points, and very low res screenshot I put up,..soz..

oddly I think we miss a point from my original post question of do you think it would work or not?

At first posters advised about how I needed a 360 rad...and yes you do if running 6 cores OC'd with 1.3v through it...but that was never my build..

I just wanted to let people know that if you're doing a 4 core single GPU, that the predator range yields very good results.

I was never doing it for any major OC value other than to keep GPU Boost stable and give me 2.1ghz out the card quietly.

And if I'm paying EK all that coin to do it, I may as well window it up and LED it up and enjoy it,,, biggrin.gif

My build was always in mind for housing kaby, to answer you question and Jay does really well Custom cooling is a hobby, an enthusiast one and not cheap I've dumped 3k into mine so far(inc g0sync monitor / extra desk / chair / ifixt kit / list goes on)..but always its a build once, apart from cleaning and draining (which the Predator will need.. RTM) , like me I;m looking an upgrade every 3-5+ years...once I have a kaby in my rig thats me done...i will watch Cannon lake come and go, then see whats what..

I was well aware of your point of the original post, that's why I have subscribed :-). It is an interesting question for those who don't necessarily want to overclock but just want a well performing and silent system. And I think you've answered it pretty well, this definitely seems like it's adequate.

I was indeed a bit curious about that picture, also as I have not used Aida64 before. So I have downloaded this in order to understand your results. What I notice is at my Palit GTX 1080 Super Jetstream is that it does not seem to work well as you can see in my picture as the Power usage and GPU usage fluctuate very erratically. Unfortunately I cannot tell what the test does to your system because we're missing the statistics, but reading up on this online I think it's similar due to the nature of how this stress test works.

When googling on https://www.google.nl/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=aida64+gpu+stress+power+usage I specifically found this thread with that answer: https://forums.aida64.com/topic/2740-fluctuating-gpu-clock-and-power-draw/

I wonder how representative that test is. If I understand correctly, it's OK

My situation (don't forget to view the original, a feature I discovered just now):


So, my system is very comparable to yours and I'm running the following with decent air flow:
- Palit GTX 1080 Super Jetstream at stock speeds currently
- i7 6700K at stock speeds currently with a Scythe Mugen 2 rev. b (currently just 1 fan but soon I'll have 2).

My temps get up to 83 degrees on the GPU on load (with a custom fan profile). At this point the fans run at 50% of the max RPM which is 1250 RPM. At this point the fans make an audible but not annoying and perfectly acceptable sound. The temps on the CPU are up to 72-78 on load (variation between cores and package). At this point the stock fan at the Scythe Mugen 2 rev B. (which is pretty good) runs at its max speed of 1300 RPM and makes an audible but not annoying and perfectly acceptable sound. Everything is perfectly stable of course and I have some room for a minor overclock. Still have to tweak a thing or two and are going to try even better CPU fans, but maybe this already helps someone in their comparison.

Interesting find on those links I did wonder why there are power fluctuations and had incorrectly put it down to just the way the GTX1080 tries to balance everything via its varying upper limits, thanks for the findings. Your temps and fan speeds sound really good. Once you have that 2nd fan on the CPU in push/pull those temps will come down a few more degrees and you may well be able to reduce your fan profile a touch also.

What I really like about the investment into the pascal architecture, is although overclocking is fun, its nice being in that position whereby you don't need to really push the card to its bleeding edge to obtain those few FPS to move a game from just playable to enjoyable at high settings.

Let me know how things go with your tweaking and your CPU fan future choices, I'll keep dropping updates to this thread as I slowly tweak and play around with things. I need to re-do the carbon fibre tape I masked my SSDs with to make them low key in the case, I can see some of the SSD casing at the sides...so a bit of aesthetic OCD to attend to thumb.gif

Again thanks for your interest and your own comparisons, as you say and I agree I hope others can find some use in both of our builds, and findings..

Until the next set of results and upgrades, I'm off to play some Doom, (actually I will post a screenshot I will play a bit using the stats console overlay which will show FPS / temps / GPU load etc

will update this evening sometime)

I have a 4790k running at 4.6GHz with 1.24v, along with a 980ti at 1455/7600, all being cooled by a 38mm thick 240mm EK radiator. That's a fairly significantly higher TDP compared to your 1070 *whoops - 1080* and i5 - it gets to around 350-380 watts at the wall while gaming (so around 315-342w accounting for the PSU's ~90% efficiency).

Temperatures I get under a demanding game (e.g. DOOM @144fps 1440p) can get the GPU to a max of ~65C, and the CPU to ~75C. Less demanding games have the GPU around 55-60. Highest CPU has got is around 80C with x264 benchmark.

If you got a kaby lake i7, you would still most likely have a lower heat output than me on both CPU and GPU. In all, don't worry, you won't have any problems. tongue.gif
