1080 GTX Watercooled temps

[stealth80]

I've had my 1080 since like October and that whole time it has been watercooled. It's a Palit Gamerock premium and it initially had its own loop in a Thermaltake X9 (360 + 240 radiator - was SLI 970's) , since then its been in an INWIN 303 which has just been revamped post my Ryzen 1700 switch.

 

So here's the set up:

 

1700 @ 3.95ghz + Ek Supremacy

1080GTX @ ~ 2.1ghz (Palit boost - not modded) with EK 1080 block

Alphacool XT45 360mm crossflow rad + 3x Thermaltake Riing 12 fans

Alphacool UT60 240mm rad + 2x EK Varder 

Alphacool XT30 120mm crossflow rad + 1x EK Varder

 

So, quite a lot of cooling for CPU + GPU. The Ryzen temps are fine 20C idle and 40 - 45C loaded. Ever since I've had the 1080 I've seen it get as high as 63C which I figured was fine looking at air cooled cards and it's clockspeed. Today I commented on a thread where the guy seemed to have the tubes connected to all 4 ports (both sides of each) his GPU and I offered advice about using one tube to each side as per EK. Anyway, that wasn't the issue, another guy popped up and said he had 1080 SLI that never went above low 30's. I initially thought BS (although I didn't say that ) as my temps on a big loop can get to almost double, so I decided to look up the subject, it seems he may be right (not an issue). I've seen people saying that 45C should be the sort of max load temp for a 1080.

 

So here's some pictures of the loops.

 

The initial one (TT X9) - White loop was for the 1080 (this is actually a picture from the 970 SLI, but it stayed the same for the 1080) - Again I seen 63C

 

 

Build now:

 

 

The block has been replaced since the first picture as it had an internal leak, so it has been reseated, I'm pretty sure that aint the issue anyway as I would expect it to get a lot higher.

 

Anyone have any ideas what my problem maybe?

The fittings have to be on opposite sides of the card vertically for a single card, as well as horizontally.

 

As seen on my rig:

 

Having them on the same face of the card will reduce flow rate considerably, and is probably leading to your slightly higher temps.

Sorry but that makes absolutely zero difference, it still goes into the block opening the same, ek just gives that option for easier fitment, both lower and upper holes go to the same opening on the edge of the block, you see it when you remove the port block to add a parallel terminal for SLI

 

Also when the card was in the first build it was routed that way for convenience which had the same temps as i'm having now which backs up what i'm saying

What's the loop order for the new rig?

that's it there, the bottom photo, but here:

 

res > pump > 240mm rad > GPU > CPU > 120mm > 360mm > res/pump

 

That's what I find weird, if the GPU was so hot I would expect the coolant to be hot and therefore (as its next) the CPU to be damn hot, but I got this Ryzen just shy of 4 ghz 1.375v and it games at like 40C

So fan speed doesn't effect it? Or is this at the quiet setting and speeds don't fluctuate?

It was quiet setting. Ive since drained the loop, removed the GPU, split the block and cleaned it out, and reseated the block on the GPU with new paste and was less of a pussy tightnening the block down, seems to have dropped temps 15C or so, but I'm normal fan speeds at the moment to help bleed the loop quicker. Gonna try quiet later

I stripped the whole build today, added a front hole and 120mm fan as intake and sprayed the rear internal panel white. Been a long day, ill update my build log tomorrow but temps seem better
