Is widely known and accepted the fact that the UD3 comes with the crappiest HS of the range. That's just a fact whether people some people like to accept it or not.
Now, changing the even crappier TIM on it should be a priority for all owners of this MoBo.
I'm kinda screw because on Argentina Gigabyte has not real representation and the people from the tech support can barely understand Spanish and/or English let alone write it. So I can't really get any type of direct contact with them, only via my retailed which he refuses to accept any responsibility unless my board burns up because of the temps (quite literally).
Changed the TIM for me dropped almost 20C. Even though I left the outer pads on, thing that I will correct on my next clean-up.
I'm trying to find some proper "bolts, nuts and washers" to firmly secure it since at the moment I don't have any money to purchase an after-market HS for my NB, specially since they are quite expensive and rare on my whereabouts.
Lately is quite hot in my city (30c to 40c) and the highest I've seen my NB while gaming was at 64C (Albeit not horrible is still crappy, woulnd't mind seeing it lower, like the Asus counterparts of lower end MoBo's), usually is around 58-60C. Before I changed the TIM was almost peaking flippin' 80C on the previous heat-wave that my city got.
The fact that it also starts at around 50C as soon as I turn on my PC after like 12 hours is just plain crappy.
Like Hippie Tech, I also believe that there is a overvolting of the NB, like my CPU vCore had it to 1.475v by default (even as high as 1.5v with the LLC on auto), which is really stupid since my chip can run at stock with 1.275v.
I will start testing the minimum voltage for the NB these days, hopefully that will decrease the heat output a bit.
Thanks for making this thread and all the inputs and ideas, Hippie Tech.
