Thermal pad on g51vx rx05 gpu?

Hi:

So recently I was repasting my gpu in g51vx-rx05. I removed all of the thermal pad(blue stuff) and applied some ac5 at the center of the gpu (the black chip).

I would like to know if the thermal pad are useful, because they were not only touching the black chip but also the area around it, i still have the thermal pad with me so should i put it back? or is it fine the way it is.


thanks

 

Ah, the trusty G51vx. I remember the good old days with that bad boy.

You should only be applying paste to the GPU die (In the attachment, the shiny silver thing with "nVidia" on it), not the other chips. Leave the thermal pads on those.

Those pink things are thermal pads I applied myself, so they'll look different.

 

oh!!!!!!! that's where the thermal pads are supposed to be? when i said i saw thermal pad i scrubbed off they were actually AT the gpu chip(where i should be applying the thermal paste) instead of thermal paste, i have been having overheating problem i think mainly because whoever sold me my laptop use thermal pad on the chip instead of thermal paste.

also i just realize that the gpu is the whole thing not just the chip.

thanks!!!!

 

Really? Dang. That's ugly.

The G51vx-RX05 was a decent laptop for a good price, but it runs hot hot hot. It takes some modding work to give it good temps. I think, back when the G51vx was the craze, I had the second or third coolest machine.

 

ya, i bought it a little over a year ago, i made a commitment to myself that i will keep it til graduation.

o btw, the thermal pad chips are called memory chips right ?


also if im going to buy a new one /refurbished say now, what would be an equivalent to g51vx back then? (good performance for the buck)

 

The thermal pads are on top of the memory chips. Since the heatsink doesn't contact them directly/very well, you use thermal pads to bridge the gap for cooling as well as cushions.

The G51vx had several different models. The RX05 was a weaker (P7350 CPU and 1366x768 screen) BestBuy variant that sold for about $1000 USD.

I sold mine back in November '10 for $665. Note that I had upgraded the CPU to a T9900 and had thermally optimized it. For an RX05 model, I don't think you should be paying more than $500 for it.

Off the top of my head I can't think of equivalent machines from other brands. There might have been a Gateway with a 9800m GTX, but don't quote me on that.

 

o yea that's what i mean, ONLY thermal paste should be on top of the center of gpu chip and nothing else should be on it, and then thermal pad are on top of memory chip.


i bought mine for 620 last year and i upgraded it to t9600.

 

Hello
Can anyone still help me on this same topic please?
I was having similar overheating problems on my G51 VX RXO5 (BEST BUY) and had to repaste but the blue thermal pads looked wasted so I cleaned them off. Since then I have repasted twice with AS5 and 2.0mm then 1.00 mm thick pads but each time the screen went dead although the CPU seemed fine. So my question is; Are there different gap specs for the pads and if so what size? I called Frozencpu.com but they told me to find the specs. I then IM'd Asus and they didn't have them. So should I just try 0.5mm on all those memory chips and AS5 on the GPU chip or use a thermal grease replacement pad which they now have. The problem seems to be getting the right gap for pasting by having the correct thickness of thermal pads.
Any takers will be welcome.

 

Your best bet it to remove the card and heatsink and experiment with it outside the case and see which sizes fit best (put the together and see if they mate properly, a torch can help inspect it inside), you can stack 2 thermal pads on top of each other to create an odd height if you need to.
