Hello,
Decided to give the latest Kelvin series cooling solutions a try... but sadly the impressions are not to expectation. The looks are there, but performance issues make it almost comical for my first personal H2O setup. I did not have too much exposure to AIO's yet, however I do not remember anything similar on the systems observed or worked on. Please read below.
And before I start I would like to say THANKS to OC3D team for doing a great job on reviews and support.
Also, I have seen the review on S24 and S36.
Setup:
Intel i7-4790k (stock)
Asus Impact VII
Corsair Dominator 16GB Kit 2400mhz
Samsung EVO 840 250GB
WD Black 2.5 inch 750GB
Corsair 380T
Corsair AX860i
S24 Kelvin (stock fans)
Case fan layout:
Front - 2x 120mm Corsair SP fans
Back - 1x 120mm Corsair stock fan
Side - 2x 120mm Fractal fans + S24 Kelvin
Testing:
The system was tested under OCCT Linpack mode with 90% used memory and AVX enabled (also with AVX disabled) stressing all logical cores.
With AVX the system would get over 85c on the cores sometimes in 2 minutes and stop the test. Fans were connected directly in to Asus MOBO, fans and pump calibrated and set to a NORMAL profile. Under more aggressive fan profiles the temperatures do not change much but does help to keep it at high 70s. However since the fan curve on all profiles at the end ramps up to the same speed - the noise coming both from the fans and the pump is very loud.
AVX disabled results in temperatures of 60c-70c with everything being almost whisper quiet compared to the previous results observed with AVX enabled.
First testing sessions were done on stock Fractal paste, secondary attempts were made on MX4 to double-check the old spread and exclude a possible problem.
Problem:
After mounting the new cooling solution and powering the system I did notice that there is a significant amount of noise coming from the air bubbles in the loop (not sure if this is acceptable or normal with AIO's as I have heard Swiftek had similar problems with their first revision).
Attempts to fix the issue were made by leaning the system side to side in order for the bubbles to settle somewhere away from the pump.
The pump is only silent at its minimal speed, going up another 200-300rpm makes the pump buzz quite a significant amount.
Temperatures are obviously high under a decent stress while running stock clock speeds and voltages.
Attempts to increase airflow were made as well by ramping up the front fans and reversing the back fan to act as an intake. In result the temps did drop a bit, but nothing that would live up to the "Silent" operation under load.
Please advise plan of action or a possible resolution.
Thanks you for your time guys.
