I have a 15.6 , i7, 8 gigs ram , HD 7970m Gaming Laptop clevo 150em for about a year now. Assasins Creed 4 Blackflag( maxed out 1920x 1080) gets my temperature ( Msi afterburner in game monitoring) up to 87C. I bought Antec formula 6 termal Paste a while ago and reaplied it on the GPU core. The first time after i newly applied the thermal paste it was not going above 75C in Assasins Creed 4. Now once the laptop cooled down and I played the game again it increasesthe temp little by little, from 75c to 77c and keeps going slowly up to 80c again ( after 2 hours of gaming). My question here is with this HD 7970m card. Is there alot of difference between pastes in genarell ?. My way of thinking here is that once the paste gets hot it spreads across the surface and then once it cooles down looses paste off on the sides of the chip. Then when it heats up again it has therefore less paste in the center. Not sure about that but does anyone has any recomendations on keeping this card below 85c with maby a different Paste ? or a cooling paste pad ? What temps do you guys get with this game with a HD 7970m. ?

what the guy says above is false theres a big diffrence in certain pasts from how easily they spread to there thermal conductivity the better the thermal conductivity the better it transfers heat to heatsink

The best paste for laptops hands down is mx4 paste

due to 1 itsnt hard to spread even
2. higher thermal conductivity then most market pastes
pros its cheap

now 5.3 is the thermal conductivity of paste you mentioned

mx4 paste is 8.5 i used this paste for a older laptop hitting cpu temps of 71c this has dropped it down to a massive 50c

note you shouldnt just apply this stuff on gpu it

should be cpu and gpu this is because it lowers overall heat inside the case

my advise
take out the heatsink cpu and gpu and give it a good clean
with isopropyl alcohol 99 percent and a microfiber cloth and use coffee filters for drying it off get it nice and shiny also clean out and remove the fan inside your laptop so you can get at the grill clean that out and blast the fan internally with can of air.

now go to the cpu and gpu chips and clean of with iso alcohol and dry of with filters get it good and shiny and then apply mx4 paste a pea size ammount on each die spread evenly with a plastic gift card so you can not see the shiny surface anymore

then reattach heatsink and tighten in screws or pins in this order 1 and 3 and 2 and 4 a lil at a time so this doesnt make the heatsink off balance.

this paste needs a few days to settle i find as my temps after applying were 58c then dropped to 50c after a week of use
