VRM Temperatures

[gozzygozborn]

Hi guys, my computer is about 7 years old at this point and up until this point I haven't overclocked it at all simply because I haven't had to, I've maxed out all the games I have played until now.  Today I turned my clock speed up on my 780 Ti to 1160 MHz and after running unigine heaven on ultra settings, 8x anti aliasing, 1080p and moderate tessellation I came out with a score of 2100. I continued to run heaven for about 10 mins and I noticed my gpu temperatures were good at 75 C although the VRM temperature was 92 C. Does the VRM temperature seem high? What should be considered in safe range?  I also noticed some stuttering on heaven, is this normal for the program or does it have something to do with my card? Thanks in advance for your input, my full PC specs are in my profile if anyone is curious.
