I am unsure why my WC setup is incurring such high Delta over ambient on idle and most importantly load.
My system specs are:
Intel Core i7 4790k @4.6GHz @1.264V
Gainward GTX 1080 Pheonix @1.075V @2,101MHz & 5500MHz
MSI Z87 GD-65 Gaming Motherboard
Corsair GS-700 Bronze PSU
G-Skill Ripjaws 1600MHz 16GB Ram
Thermaltake P5 ATX Case
WC setup:
EK Supremacy EVO CPU Waterblock
EK-FC1080 GTX JetStream - Nickel
Alphacool NexXxoS ST30 560 Quad Radiator
EK CoolStream XE 480 Quad Radiator
EK XRES 140 Revo D5
PrimoChill PrimoFlex Advanced LRT Tubing Red 3/8ID 5/8OD
4 x Corsair SP 120 (1550RPM)
2 x Corsair SP 140 (1440RPM)
Loop order:
Res > Pump > GPU > CPU > 560 > 480 > Res
Problem:
GPU under load within 1 minute reaches and stabilizes at 52-55C @100% fans with adequate flow rate from pump. I am seeing other people report max GTX 1080 temps of 38-45C or delta's <10C. If I run my fans at 50% I can expect GPU temps to hit 55-57C. Over the past few months of using the PC, my GPU temps have always seemed to be in the mid 50's range regardless of ambient temps whether we experience 40C hot days or 25-30C days I have never been able to run consistently <50C on GPU.
I have reseated the GPU block at least 4 times and have used MX-4 thermal compound. It appeared to be making good contact with GPU die. I did have to replace the thermal pads of one side of the memory bank as there was a gap and wasn't making contact with the required 0.5mm thermal pad. I installed a 1.0mm pad and this has solved the problem for that. I doubt that has offset the GPU block as my temps before this were still hitting 55C max since I first got the block.
CPU under Aida64 with all CPU parameters ticked hits around 65-70C across all cores under load (dellided)
I do lack measuring and temp sensing equipment and will get a water temp sensor within a week to figure out what is going on.
Any advice in the mean time will be appreciated. But from what I can tell roughly, my ambient is around 25C and is quite humid currently. Before booting my PC I felt the water temp inside the res and it was cold of course. After gaming for a few hours, the water temp seemed almost the same, it was not at all luke warm or hot, but it did feel a few degrees warmer. Fans are running full tilt at 100% 1550rpm for the 120's and 140's at 1440rpm. Pump is a D5, running at about 2400rpm (55%). Air has been bled out from what I can tell almost completely by running pump at 100% for the first few days since I added the 560 rad, and tilting PC case.
