Welcome to the EVGA forums
"Precision X, HWMonitor & Speccy..."
These programs can -cause- the fan ramping issue you are describing, by fighting over sensor polling on the card and/or becoming abnormal because of corrupted data.
---This would appear to be what has happened to you---
Question:
Are you using ANY other "software" for your case fan controls (SpeedFan, Gigabyte MB software..Etc) or are your fans and H110 simply MB fan header BIOS controlled?
---------------------------------------------
Use of too many programs that try and poll the same sensors (videocard temp and fan control sensors) can lead to whats called a SMB conflict.
This is made much more likely as many programs are NOT working correctly in Windows 8.1
The recovery and testing should be fairly simple
*NOTE: do NOT skip any of the reboots listed in the recovery below
Shut down and completely Uninstall HWMonitor, and then reboot
Shutdown and completely Uninstall Speccy, and then reboot
Shutdown and completely Uninstall Precision
*Important: During the Precision uninstall--> a box will come up for saving data that has "yes" as the DEFAULT
You MUST change this to -NO- and NOT save that Data as it may have become corrupted
After the Precision uninstall is complete, you must reboot the computer once
After rebooting, you may put Precision back in (only the latest version 4.2.1)
*it is suggested to uncheck the RTSS (riva tuner) addon during the install.
Leave the program at 100% defaults, except for "Start with Windows"
For now leave the Precision fan control at DEFAULT (for now)
You should now test
Use Heaven 4.0 for testing, as its Win 8 and SLI behavior are well known
----------------------------------------
*if you have "other" software that monitors videocard temps and/or monitors or controls fan speeds such as SpeedFan, AIDA or -any- MB addon GPU monitoring/control PLEASE POST WHAT PROGRAMS YOU HAVE INSTALLED
Also, please post what computer case you are using....
ACX cards are not ideal and can be problematic running in SLI without the proper case and airflow.
