This is just what I would do, someone may say its dumb.
this is the best answer i have seen i will expand further on this in a bit

If there is no little to no rise, then your current fans/radiators are perfectly capable of dissipating that heat and an upgrade won't give you much of an improvement.
this is something completely different
first is temp spiking ( running w.e. for 1 min ) this means literally nothing in a pc
you are talking about temperature saturation ( the water in the loop raising to its max temp )
every system will do this however unless you do certain things ( render/encode, fold/ect ) very unlikely this happens in day to day useage , most of the time you deal with mini temp spikes saturation temps will vary based on load - ie gaming will load the gpus more then the cpu but it could saturate the water more then a cpu only 100% intensive load
you can lengthen time it takes to reach saturation but all loops have a saturation point

I currently have the CPU on a dedicated loop with a 240mm rad
. The loop is expandable (It is a Swiftech H240-x). Under heavy load the temps are reaching around 85C
. This is a HEAVILY
overclocked CPU with a lot of voltage pumped through it (X5470).
I'm looking for other's opinion if you think an 85C CPU already under H2O with a dedicated 240mm rad would get lower temps under load if I expanded this loop by adding another RAD
I'm just not sure if it is going to improve cooling in this specific example. Have I already maxxed out RAD space efficiency or do I have room to go? This is where I am 2nd guessing myself and I think it comes down to rad space efficiency and I am just not sure if I would be wasting my money by expanding this loop or would it be worthwhile (and see 5C or more improvement)?
Thanks in advance for your thoughts if you think expanding my loop for this CPU alone is worth it and what I might expect for temp reductions if I did based on your experience.
Well all the above answers are good, but I figured I would come in with the easier one, yes.
My CPU is ost likely pushing more voltage than yours while benching as I push kill my chip voltage. Even then my CPU doesn't go over 65c, with the GPUs loaded at the same time.
To give you an example my CPU is 130ws stock where yours is 120w, I run my chip at 1.52v when benching when most people will tell you not to go over 1.4 even my 24/7 is 1.45 lol. Adding another 240 or very fast fans should give you much better temps. My staying under 65c is with 3 480s worth of rad space and 2 overclocked 290s.
i have more voltage and my tdp is higher? and i have more equip in my loop ? ok, great answer in that case i run a 3930k @ 4.8 2400 ram and 2 295x2s with 5 480s and 4 mcp35xs and mine usually never break 60 however that i dont think helps him at all

Yup and we're thinking along the same lines.. Who cares when $60 buys you a replacement CPU lol. I may actually be running more voltage after all
This is my "24/7" config! I've actually been running this over a year and it's solid so far.
You bring up another good point though...I chose to place my CPU on a dedicated loop because my thinking was that my OTHER
loop is going to be working hard to keep my chipset and (2) GTX 980Ti's with a MOD BIOS cool and throwing the CPU into the mix would be expecting too much of it. Everything is running in "PULL" to minimize dust buildup in the RADs.What my layout looks like, I was leak testing here (Click to show)
My other loop is a 140mm + 420mm for RAD space (Total of 560mm). All my RADS have Noctua NF-A14FLX fans
. Currently that loop is not working hard at all and is likely overkill (the way it should be
).So based on your example (with a lot of RAD space) should I actually consider combining the two loops into one?
If I got rid of my MCR-140x (140mm RAD) and joined my GPUs and Chipset to the H240x (240mm) it would give me a total of 660mm of RAD space. I suppose I could also
just put another 140mm rad back where the MCR-140x was (once removed) and that would give me a total of 800mm...
Do folks think that's a better option (to combine my loops into one) than to try and add another RAD to my dedicated CPU loop?
for the most part dual loops are for looks, otherwise useless. so yes you should combine them there are reasons to run dual but tbh you dont need to, if you combine then it will be overkill for everything
the only real way to answer your question is a problem, you need a water to air temp delta to tell you what you need to know, do i think another rad may help yes- but there is far too much for me to assume, your block mount is a big one, another is how you are controlling your loop
the one thing that can negatively affect your build if you combine loops is you are now running through 3 blocks ( most chipset/mobo blocks are not restrictive enough to count ) cpu and 2 gpus that restrict flow, you should be fine though with both pumps ! but you may have to run them higher then you would like,
a LARGE improvement ( however it is costly ) is a aquaero you can program the aquaero to run from a water-air delta which will assist in getting the best temps for you !
