laptop gpu is dying

[Steampunk755]

hi all i got a hp dv7 3 months ago, i often use it to play games but in the last time my gpu is getting hotter. at first i got 66c under load, 3 weeks ago 67c, 2 weeks ago 68c. and now hits 70c. i already cleaned up the fan but nothing.
ah here are my specs:
hp dv7-4117ez
n930 quad 2 ghz
hd 5650 OC 25% 550/800 --> 675/1000
ram 6gb
500hdd 5400rmp
win 7 home 64 bit
ps: without oc i got the same temps

That is a 2010'ish model machine for just getting it 3 months ago, did you get it used or refurbished?

Based on the age and the fact that you have it OC'd, I would guess that you need to redo the thermal paste if cleaning the fans did not help. I would dial it back to factory clocks and check temps first though, and then go from there.

yes, i bought it from a friend. so should i reapply the thermal paste. is that difficult on a laptop?

If those temps are with an overclock, I wouldn't be worried. A gpu can handle quite some heat.

I agree those temps aren't currently at alarming levels, but it appears they are rapidly changing to higher levels which could be something to be worried about (which is the OP's main worry I think). Based on the age of the laptop and that some of those models are known to have heat issues due to a somewhat poor chassis vent design, I would highly consider re-doing the thermal paste in the near future. There are quite a few video's on youtube you can follow that are probably even model specific to yours.

Edit: Depending on your comfort level with this sort of thing a combo of new thermal paste and copper shimming (if gaps etc.), would probably be ideal. I'd check out some video's first and see what you think.
