applying thermal paste on G73jh

So I took apart my G73jh to re-apply the thermal paste (with arctic silver 5) on the GPU due to overheating issues, and once I rebooted, its overheating worse. My question now is, is there a difference for applying thermal paste to the GPU than PC CPUs? I usually apply a paper thin layer of arctic silver, and call it done. It seems the GPU mightve needed more.

My other question is around the thermal pads. Should I have replaced all the pads on the ram etc as well? I only replaced the thermal paste on the GPU itself.

My memIO now jumps to 110 in 3 minutes of some wow whereas before wow was fine but SC2 killed it.

thanks in advance for your help-

before I was idling at 74, now I am idling at 82..

 

There were a few posts in one of the gpu temp related threads where people posted pictures showing that the thermal pads provided by Asus are too thick. So if that is true then replacing the thermal pads might be useful.

I tried reapplying thermal paste on my cpu and gpu on a sager using the spread super thin method. The cpu was fine, even better temperatures but the gpu would overheat instantly. So I decided to just put a drop in the middle and it worked out fine.

Watch this and tell me what you think about your application method.

 

too much thermal paste... apply a drop and spread it.

 

Or get some better thermal paste like IC Diamond and put a Pea sized drop in the middle of the die and put the heatsink on without spreading it. If the pads are too thick like people say than AS5 is most likely too thin.

 

Depends on the grind/cut of the heat sink. Thermal paste just improves the contact area and makes up for crap grinds. If youre going through the trouble of doing the thermal paste you should lap the heat sink. Its worth the 20 minutes of time. Then use the compound.

 

I'm confused about the drop in the middle method. Do you apply the drop and twist the heatsink while applying slight pressure to spread it? Or do you just stick the heatsink straight on over the drop and let the natural pressure work?

 

Don't you have to take apart the whole g73jh to replace the paste? This is one of the reasons why I decided to keep my g51..

 

There are tons of ways to do it. I use ceramic paste and spread a thin layer then press and twist the heatsinkbefore I bolt it down. Have always had great results. Everyone has the way they like to do it.

I dont like the dot method because you cant guarantee that youre going to get great coverage.

 

So I took a shot in the wind and came out successfull. I ended up putting huge globs of AC5 on all the memory blocks, the GPU, and anything that had a thermal pad on it (which was originally my question) and it lowered my temperatures by 40 idle, 30 in game (SC2 after 3 hours of play). Overheating problem fixed. I Feel I probably could've thrown a bit more arctic silver on there as I ran a little short due to buying the smallest tube (didnt know I'd be using huge globs), so if I have overheating issues any time in the future, I will probably just throw some more at it. It goes against everything I have always done with arctic silver, but it worked!!

To the commentor about taking the laptop apart, yes, the GPU is one of the last pieces you can take off (theres the CPU and a couple USB boards left once you get to the GPU) but I have the process down to 10 minutes to take it apart and 10 to put it back together. Replacing the monitor took more time than rebuilding the whole laptop (just so many screws).

I appreciate the video that was posted, though they do not show the arctic silver air bubbles when it is applied in a thin line which is my normal preferred method of choice, just the ceramic.

 

I hope you realize that AS5 will thin out as it gets warmer, right? That should cause gaping and rising temps. You really should have used pads for the memory.

 

Chastity, since you did a re-paste, about how large is the gap between the vRAM and heatsink, about .5mm? Or 1mm? I was wondering if I should do a copper mod on the vRAM to help bridge the gap since it'd be better than pads.

 

just checking in, did a week of gpu testing after my repaste, highest it gets now is 90 under full load in a hot room

 

The gap is dependent on the heatsink you get. For me the gap was less than .5mm everywhere so I replaced the pads with new .5mm ones.
