Undervolting & Cooling an HP dv6tqe-7000

I oftentimes use my HP laptop for moderate gaming, and with programs such as core temp, hwmonitor, and Intel XTU, (yes, i have all 3) I've found that my cpu and gpu become quite hot during gaming. The cpu can easily reach 90C after playing an hour of Civilization V, and reaches similarly hot temperatures playing other games. I've already lowered the maximum processor state to 99% in the battery settings (I've also tried 80% but temperatures were equally hot) and blew compressed air into my vents about 2 months ago. I'm now looking to undervolt my laptop as I've read that it can greatly help in reducing temperatures. I have a i7-3610qm and a gt650m on my laptop.

My question is if it is even possible to undervolt my laptop, as the sliders in the intel XTU are all grayed out, and if so, how should I do so safely without BSODs. If there's a BIOS setting or something that could help fix that, that would be awesome.

In addition, if undervolting is not a possibility on cpu, is it possible to also undervolt the GPU?

Finally, if undervolting is not possible at all, what other methods should I use to reduce cpu and gpu temperatures? I should also note, I have a cooling mat below my laptop with fans, and the 90+ degrees C includes using the cooling mat.

 

I have a similar laptop and I don't think you are able to undervolt the cpu or gpu, but correct me if I'm wrong. I also have the same temp issues but even running at those temps, my computer hasn't ran into any of those problems during the 2 year ownership of it. Although there are some people that repaste their cpu & gpu and do some cooling mods, you may or may not try it if you are confident or comfortable with the risks it might bring.
