Laptop idles in the mid 60s and goes to 70 with just Youtube so I want to undervolt to lower the temp. I've tried Throttlestop and Intel XTU but there is no way to limit the voltage(no options under Advanced Tuning in Intel XTU.) What other apps can I use or how else can I under volt for cooler temps? I'm still on 4GB RAM, will going to 8 help with lowering temps?
