did i damage my clevo ???

my p170em with 7970m started to over heat of late hitting 98c after an hour of high utilization , so i thought maybe i should dust out the gpu heatsink . i opened the back of the laptop removed the heat sink then blew air into it and removed the thick dust that accumulated there but without re-pasting cuz i didnt have paste at the time , i returned everything in its place and fired my clevo , i ran 3dmark11 and heaven dx11 benchmark to be surprised that my performance dipped down !! i used to get 6400 in 3dmark11 now im gettin 5333 and in heaven dx11 i used to get 82 fps now im getting 67 , i watched the temperature and it isnt any worse than before i opened the laptop , what went wrong ??? is the laptop performance dropped cuz i didnt re-paste and now the heat is hurdling the performance?? please help !!

 

It's throttling because of the thermal paste you had better benchmarks before because it took longer to throttle but it still was get some paste and don't use the machine until you do

It's always a good idea to repaste every time you remove the heatsink. I don't think you damaged your machine, but I would avoid putting any stress on that graphics card until you buy some paste and do a proper repaste.

 

The paste was likely dry anyway and when you took the heatsink off and did not refresh the paste it means while the dust has been removed the contact is now poor.

 

You removed the heat sink, but didn't repaste? Not the best idea, as it will get air bubbles and other issues so it won't fill the gap right. Also some paste just needs to be replaced every six months, Like Diamond paste. So maybe it needed to be changed any way. Other things can also hurt your scores, like background tasks. But start by repasting since it doesn't cost much.

 

so as not to under-emphasize the point and with four people having already said the same thing, what would make you think it's okay to re-seat a heatsink without re-pasting -- and then run a benchmark? if you didn't damage the chip, you should have. i'd be embarrassed to even ask this question. no surprise you were hitting high 90s beforehand too.

 

Hey no need to be rude, 4 months ago I had no clue what "repaste" meant. Everyone was a beginner once so cut the OP some slack. I'm sure he's got the message by now.

 

OP clearly stated the heatsink was re-seated "without re-pasting cuz i didnt have paste at the time." what does being a "beginner" have to do with anything?

 

Perhaps OP didn't realize you need to repaste every time you remove the heatsink? I'm just saying OP has learned the lesson, so no need to rub it in further.

 

i think OP will be okay. not to mention other people read this board, ya know? we wouldn't want any beginners to think it's okay to benchmark an improperly assembled system, would we?

 

this is my first laptop and as a first timer to this i watched couple of videos like this one Clevo P150em disassembling ( CPU+GPU ) - YouTube where he didnt re-paste so please dont go all wisecracking on me . on another note , i did re-paste but the temperature still rocket at full load and somewhat settle at 97 with the same reduced performance , not sure what is wrong , the fan sound awful quiet to me also , i did get a generic thermal paste cuz where im there is no specialized shop for this stuff , please help

 

i re-pasted my cpu with the same the thermal paste and it seems to stand the heat just fine under full load ranging between 80-86 with prime95 , but i noticed my gpu fan stuck at 35% untill the temps hit 95c that is when it kicks in to 100% even though that doesn't do any help from stopping the temperature from hitting 100c

 

80-85 isn't great temp CPU wise. What kind of paste do you have? What have you been cleaning it off with? Have you flashed your BIOS with something else? The fan should throttle up before throttling like that happens.

Did you repaste your GPU too? Check the heatsink is properly secured and the thermal pads in the correct places.

 

okey sorry about this but it turn out i confused my gpu with my cpu , thought my cpu is actually the gpu and i was pasting it , well after i got things right , i pasted the gpu but even after that when i ran swtor temps reached 100c while i was playing , i cleaned the chipset from old residue paste and the heatsink plate , but still even after the fresh paste the temp sky rocket at 99% utilization, could the chipset be damaged and it is overheating cuz of it?when i bought it my 7970m never went over 83c , now this is a thing of the past

 

If it's clean, the paste job is good, the pads are applied properly and the fan is plugged in and spinning normally then the heatsink may be damaged and need replacing.
