Not liking all the noise from the stock GTX690 fan. GPU will be going onto water hopefully in the next 2 months.
Thermaltake Water2.0 Extreme seems to be doing ok. I replaced the 2 stock fans with 4 Noctua's in push/pull. Idle is about 30C and load is near 70C (OCCT). It's not fully tested for stability yet, but I think 1.2Vcore and 1.5Vpll is close to the mark for 4.6Ghz turbo. Not interested in a super high overclock, more like a good 24/7 that will last for 4 years.
Does anybody have any suggestions on a good way to wire the Water 2.0 & the 4 Noctua's (3pin)? Right now I have the Water2.0 plugged into the CPU (4pin) header, 2 of the Noctua's go into the Water 2.0, and the other 2 are plugged into the CPU_OPT (4pin) header with a Y-adapter. The problem is the Notcua's run full speed all the time and I want them to slow down during idle periods. I really don't want to pop another $100 on the newer 4pin Noctua's. The ASUS fan controller software doesn't seem to do as far as fan control goes with the current setup (BIOS fan control doesn't do anything either).
Also, for some reason I can't get this system to wake from hybrid sleep. The system turns on, but monitor, keyboard, and mouse do not come on.
