Update: it has been about a year and the warranty has also finished. i took the back panel off for maintenance, and was surprise at how easy it is to replace the thermal compound and clean the dust. since i game quite a bit and do live in dubai.. i clean my laptop every year from dust and every 2 years i replace the thermal compound (AS5) .. when i pulled apart my fan i observed the heatsink and it was over 50% blocked...but while i was using to computer for gaming and monitoring temps.. they never exceeded 85c .. so the cooling solution inside this laptop is very efficient to the the least. i clean both the fan and the heatsink and proceeded to replace the thermal compound as.. although was still very effective. was not as efficient as arctic silver 5.. after this maintenance/upgrade. i managed to overclock my gpu just above 20% .. (cpu i7-4700mq, 8gigs of 1600mhz memory, 1366x768 glossy TN panel)
my gpu is a r7 m265 2gb ddr3 .. (renamed hd 8750m) before thermal paste replacement with out the overclock my gpu reached a maximum of 78c during a 4hr game of bf4. after the overclock and thermal replacement .. it never surpasses 72c. cpu on the other hand was also an improvement . before the thermal upgrade the cpu ran at around 86c during gaming (bf4) after the upgrade im pegged at 78c ... but b mindful that these are very intensive games. if i played a more casual game like league of legends or team fortress 2 .. cpu maxes out at 70c (before 75c) and gpu with OC at 65c (before 72c)... the only way i actually managed to overheat the laptop is with furmark + prime 95 which in this instance resulted in a cpu temp of 100c in about 10min and gpu maxed out at 85c .. (the cpu and gpu are connected to the same heatsink.. so when i overclocked my gpu my average cpu temp also increased a little bit but as you can see barely) but this is a very unrealistic load you can definitely expect this not to happen. but if you where to individually load the cpu or gpu they never experience any throttling what so ever. (in the sense of video editing or photoshop ) but even then the load % for both these where 100%.. when i ran furmark stressing my gpu completely while holding my cpu at a 90% load ... the gpu maxed out at 83c and the cpu maxed out at 88c ... still way under the danger limit......so to summarize this reply completely , the laptop indeed has a very effective cooling system that can handle both components under load in most cases.
if you never played games and only use this laptop for wed browsing and school .. then overheating will not become a likely issue for at-least 2 years (provided you live in a dusty country like me) but if your a casual gamer then expect to get your laptop cleaned at least every year or every six months if you live in a dusty environment.. but it you game excessively like me and live in a dusty environment , then i recommend a dusting every 60-90 days. oh and all this testing was done is a ambient temp of 30c.. you you lived in a much cooler climate such as Europe or Canada, with a ambient of 22-24c , then expect temp to be proportionally cooler.. and if you live in Britain and its winter, where the ambient can ball below 0, well even under max load for both components, you max temps will likely stay in the 80s.. hope this helps everyone... (PS:- all this extensive research was done just for you g510 owners.. AND if you have a i5 , take everything you say about temps and minus about 15-20c depending on you ambient temperature) cheers everyone, and i hope this help all of yourll and a reply on what you guys think is greatly appreciated
