Just as the title says, could temps of 95-107°C on the VRMs be affecting overclocking potential? The GPU core itself never exceeds 80°C.
My personal experience with the card stated has been that it is rock-solid stable at 1455/7810 with stock voltage in everything I've thrown at it over the 3 months I've owned it - watch dogs, GTA V, modded skyrim, Tomb Raider etc. VRM temps at stock voltage never exceeds 95°C.
If I try to go past this overclock by adding additional voltage, I am unable to go further than 1468 MHz on the core without artifacting, tested in 3DMark (Firestrike), even with +100mv, monitored by HWINFO. The VRM temp also increases to up to 107°C at the highest voltage setting.
The various forums online suggest that the VRM circuitry should be fine up to 105°C, as in not break, but I wonder if such high temperatures might be hindering the ability to supply ample power to the core. I have seen no obvious fluctuations in power or voltage, so it does not seem the case through the monitoring software.
I am using this modded bios to remove power limitations.

It seems to me that there are three possible answers for why I can't go past 1468 mhz: High temps on the VRM, some sort of issue with my modded bios (I did the modifications myself after following guides), or a core clock wall (I am not even sure if that is a thing with GPUs, I know it is with CPUs).
If you think that lowering VRM temps is a good idea, then suggestions on what form of cooling for them, where to get it and the best places/way to apply it would be greatly appreciated, I am located in the UK
Also info on ASUS' policy for removing the cooler would be helpful, things like whether getting an email confirmation to allow removal of the cooler without voiding warranty is a good idea or not, I know it was for MSI.
Any opinions, ideas or feedback would be greatly appreciated
