Hello everyone.
I have a quick question for you all. I am building a custom PC and im going to heavily overclock the CPU and the GPU. both pieces are going to be water cooled (custom),
i7 6700k OC
GTX 1070 Xtreme G7 OC
32GB Gskills 3200mhz DDR4
1000W EVGA PSU with 80 Gold
Z170X G7 MotherB
SSD 1TB Samsung
Case Corsair Full Tower ATX 750D
The purpose of this system is going to be 4k ultra settings on almost any game. going to be run on a 4k monitor.
*GPU is going to have a full nickle plate water block.
My questions are:
1- A 360 radiator (a fat one) with 3 high performance fans (2000rpm) is enough to cool off both overclocked CPU and GPU?
2- Can I have two radiators ( a 360mm and a 240mm ) with only 1 waterpump/reservoir? ( water presure in the loop is going to be ok? )
3- Is it safe to run the loop from pump>360rad>
CPU>GPU>240>back to pump? ( the coolant is not going to be hot enough when it comes out from the CPU?)
4- My main concern is the hot coolant going from CPU directly to GPU. Is it better to send the cooland from pump>360rad>CPU>240rad>GPU>back to pump? ( the coolant presure is not going to be low in this setup?
I have done months of researches (reading, watching, pictures..) but im still confused. I know the loop is custom and everyone can do different but I am trying to understand those 4 questions plus how to get the best performance. I would rather go with ONLY 1 radiator if its going to be fine.
Appreciate it everyone. This is my first post on this website, I would like to throw the final pictures on this threat. Its going to be a black/neon green setup. I named it Nuke
Thanks again
Well at the risk of getting crucified once again here going against the good ole boy club.
I see nothing wrong with your listed specs but the 32g of system memory I only run 8g of system memory and my setup is dedicated to gaming and I never use all of the 8g.
I originally bought 32g myself and ran 32g, then 16g, watching the memory usage in task bar and finally settled on 8g and even the 8g never gets fully addressed, however I am still running Windows7.
As far as the GTX 1070 Extreme G7 OC handling 4K Ultra Settings on almost any game, IDK, my GTX 1080 handles everything thrown at it at 1080P, but I am not running a 4K monitor yet, so what the little brother can do on 4K, IDK.
The power supply definitely keep that, is it overkill?, Yes, but running your setup it will run very cool and you'll probably never even hear the cooling fans have to kick in.
Definitely keep the 1T Samsung SSD, you won't regret that.
Otherwise your specs look great!
Before I answer your questions I want to make note of what you said:
I'm going to heavily overclock the CPU and the GPU.
First of all when you run it all in a single loop and combine the GPU TDP and the CPU TDP you are going to limit how far you'll be able to heavily overclock the CPU simply because the GPUs added heat load is going to affect how high you overclock the CPU stably.
My response to your questions:
1- A 360 radiator (a fat one) with 3 high performance fans (2000rpm) is enough to cool off both overclocked CPU and GPU?
Of course it can cool it, but what does that mean relating to your goal of heavily overclocking the CPU and GPU?
Will you be limited as to how far you can push your CPUs overclock with the GPUs heat added, yes you will!
You would be better off to run 2 loops one for the CPU and a 2nd for the GPU and isolate those TDPs from each other that would allow you a higher CPU stable overclock.
Keep in mind the GPU you're getting is already OC'd out of the box, and anytime you buy an already overclocked GPU some of the overclocking head room is already used.
So I suggest 2 loops and run the thick 360 radiator on the CPU alone and maybe a 240 for the GPU loop.
2- Can I have two radiators ( a 360mm and a 240mm ) with only 1 waterpump/reservoir? ( water presure in the loop is going to be ok? )
Of course you can do that but it will still be a single loop and even with the added 240 rad, the combined TDPs will still be affecting the CPUs overclock!
It absolutely affected my CPUs overclock running the CPU and GPU on my Watercool MO-RA3 which is the total cooling field area of 3 360 radiators.
3- Is it safe to run the loop from pump>360rad>CPU>GPU>240>back to pump? ( the coolant is not going to be hot enough when it comes out from the CPU?)
Many claim loop order doesn't matter but keep in mind the coolest water is coming out of the radiator, so IMO, it just makes good sense that the coolest water goes directly to what is being cooled.
4- My main concern is the hot coolant going from CPU directly to GPU. Is it better to send the coolant from pump>360rad>CPU>240rad>GPU>back to pump? (the coolant pressure is not going to be low in this setup?)
That concern is a very good reason for running 2 loops and isolating the CPU and GPU heat load from each other.

Welcome and I sincerely hope you get the answers you need!
Good luck on your build! SS
