Custom loop. Why are my temperatures so awful?!

[DreamAgainXI]

So my custom loop is:

XSPC Twin Pump/Reservoir (Two D5 Pumps 5.25" Reservoir)

1x 360MM XSPC RX360 Radiator  (In Pull with SP120's)

1x 240mm XSPC RX240 Radiator  (In Pull with SP120's)

 

Cooling:

I7-4790k at stock speeds, 1.2v with an XSPC Raystorm Pro waterblock

EVGA 1080 Hydro Copper running at 2088mhz

 

Loop order (if it even matters) is

Res -> 240mm -> GPU -> 360mm -> Through motherboard bridge (for the looks) -> CPU -> Res

 

 

Ambient temperature in this room is on the cooler side (21-22 celcius).

 

 

Idle temperatures are:

29c for GPU

33c for CPU

 

GPU idle is fine.  Off the bat I feel like my CPU idle is a little high but obviously nothing to be worried about.  Problem is when I start putting some stress on my computer.

 

So just typical gaming temps after 30 minutes of gameplay are:

44c for GPU

54c for CPU

 

 

GPU seems a little high but it's the CPU temperature that is really starting to annoy me.  I have reseated the CPU block multiple times.  I spent the entire week bleeding the system for any possible air bubbles.  Any suggestions on what I am doing wrong?  I recently went from 3 highly overclocked 980's to one 1080 and changed the order loop.  I thought my CPU temps would shoot down a lot after this change but they haven't changed at all.

 

A. I changed CPU waterblocks a while back and there was absolutely no difference in temp changes

B. Is it possible running the loop through the motherboard doing something? Ruining water flow or something?  Would have to drain the whole system and change loop so would like to get an opinion on that first

C. Is it possible it's the actual motherboard I am using?  Creating more heat or something?

That seems to be a perfectly fine temp for that loop and setup. Thats only a delta of about 15 degrees for the CPU

Hmm you think?  I am shocked at it always being above 50c without any overclock (it's actually undervolted a bit).  My only other experience with watercooling was on my i5-3570k and that would always hover in the low-mid 40's even with a very high overclock.

 

Hovering at 55c I feel like I have almost no overclocking headroom because I don't want it to leave the 60's.  Am I just being too anal about my temps?

The idle temp for my loop whit one 360mm radiator is

CPU Intel core i7- 6850k at. 4100MHz :34°c

GPU nvidia 1080(stock) :37°c

So I would not wurry if the blocks weren't seated properly you would see temp much higher

 

Full stress test CPU:62°c. GPU:55°c.

Those temps are spot on.

That's similar to what I see with a similar setup.

I agree, those temps are very nice, I would be very happy if I had those temps. I'm around 35-40C idle for GPU/CPU for ambient temps being around 21-23C.

I have about the same loop as you with about the same components as you, and I have the exact same temps. 55c on a CPU under stress is very good. The real difference is you COULD overclock and overvolt and the temps wont rise (to a certain extant)


(fyi I'm running a 6700K @4.7GHz 1.38V and a gtx 1080 G1 gaming @2050MHz 108% power limit, and I have the same radiator space, though mine have a low count of fin per inch (17), and they are slim)

[Mick Naughty]

Same temps on my rig with the same CPU @ 4.7. I'm using a 360 & 280 but the system has 8 blocks in it cooling almost everything. 

 

I wouldn't worry about the temps right now. 

[Eddie Current]

I offer this as a layout to ponder.

Now compare to original setup with air cooling,

 

So just typical gaming temps after 30 minutes of gameplay are:

74c for GPU

64c for GPU

 

If you think 15C extra is high, then 45C extra with air cooling must be the end of the world because obviously it's triple that so its high, HIgher, HIGHest!
