While Prime95 tries to kill it, I will lay out the current (and most likely final) configuration on the Ammo Box.
I7 4790k OC to 4.4
Gigabyte Z97-UD5H
GSkill Sniper DDR3 1833 4GB x 2
EVGA GTX 780 Ti SC w/ Ref Cooler OC'ed 143/167 @ 106% voltage
Intel 530 SSD 120GB
Intel 730 SSD 480GB
Seagate 1TB HDD
Corsair H60 Cooler w/ 2 GT-15 in push pull
(Soon to be replaced with an H80I)
Aquaero 5 LT controller
2x Corsair QF140 intake fans
1X Notcua Industrial NF-A14 2000rpm 140mm bottom intake fan
Here is the airflow setup:
And the Aquaero sensor locations:
Bonzai, you were correct in recommending the Aquaero 5 LT, it really is a great unit and the software is even better. The downside is a bit of a steep learning curve and limited set up info on the web.
The combination of the software sensors I could access and the 4 sensor included with the unit gave me the ability to read the temps in different areas of the airstream and adjust the fan speed curves to the temps and then build software controllers to manage them.
They are setup as follows:
The push /pull GT-15's on the H60 are linked to the CPU core temp - Fan speed at 10% @30C to 100% @ 60C
The Lower front Corsair QF 140 and the Notcua NF-A14 both run on a single curve controller linked to a virtual sensor. The virtual sensor is a composite of the 3 internal hardwired temp sensors. Their average temp is then used to create a single reading for the curve controller to follow; Fan speed at 10% at 23C to 100% at 28C.
By measuring the temps under and over the GPU and up in the dead space by the memory as well as the intake area of the H60, they react very well to loads on the GPU and chipset. The Bottom fan is somewhat limited by the proximity of the case bottom to the floor so I cut out the case under the fan to help it breath. I may build some 1" spacers to raise the case off the floor. That being said it blows outside air directly into the 780Ti blower fan and drops the GPU max temps by more than 5C.
I found that the GPU under load radiates quite a bit of heat and because the H60 is drawing air from inside the case right above the card, the CPU temp gains 1-2C if the GPU is at 50-60C under load. For this reason, I control the upper front intake fan separately from the other intake fans.
The upper front Corsair QF 140 that blows directly at the GPU and the H60 is also controlled by a virtual sensor of the CPU and GPU temps on a single curve controller as follows; fan speed at 10% @30C to 100% at 60C. Testing shows this fan @100% has a small affect on the GPU (1.0 to 1.5 C) but a big drop for the CPU at 2.5 to 4.0C as again, it is blowing directly into the intake of the H60.
The box is dead silent during non gaming use; the only thing I can hear is the pump, just barely. Running CPU or GPU benchmarks it makes some noise, but less than the two XPS Dells I have. I believe that by upgrading to the H80I and dropping the 780Ti back to stock clocks (over clocking this beast is overkill anyways); I can lower the noise by pulling all the fan curves down by 15 to 20% and still maintain temps.
Observations:
Removing the side panel on the MB side actually RASIES the CPU temps while dropping the case temps. The GPU doesn't seem to change temps with the case open. I believe the loss of case pressure hurts more that the benefit of more outside air flow.
The H60 is useable, but not any great shakes over an air cooler. I think it's more of an " I have a water cooled PC" thing than a real world cost benefit over air cooling. I have mine running at 46-48 full load over ambient after a LOT of work. Push/pull, sealing , adding a shroud and lots of airflow/ pressure to feed it.
Hopefully, by adding the GT-15's and sealing the H80I, I can keep the 46-48 with lower fan speed and noise.
The Box has been running Prime95 for 9 hours now and seems fine. Yea!
Here are some numbers.
Intel BurnTest at very high 10 passes 22.23 ambient 68C max CPU temp
Prime95 blend for 9 hours 21.85 ambient 70C max CPU temp
FurMark! GPU Test 30 mins 22.73 ambient 68C max GPU temp with card overclocked
FurMark! GPU Test 30 mins 22.26 ambient 66C max GPU temp with card stock clocked
Heaven 4.0 Ultra/ 8xAA 1980 64.4 FPS stock/ 70.1 overclocked.
The H80 gets here tomarrow..............back to work!
