ASUS G73JH Thermal Pads

I would like to ask a question about the thermal pads on our G73JH, you see here are my temps right now:





As you can see, I have 99 Degrees on my MemIO, my question is, the MemIO is the VRAM right? So does this mean my thermal pads are kinda fail? If so what would you recommend to replace it and where to buy. Would love links to International sellers if possible.

 

Not necessarily it would appear that your paste might be degrading from the difference in the temperatures as its very similiar to my experience. Take a look my beginner repaste guide in my signature below and take a look at my screenshots I would expect your GPU paste job looks similiar to mine in that gaps had occured at sections of the GPU, dried up and clearly an Asus attempt.

Might be an idea to blow compressed air into the vents if you are staying below 100oC as a quick fix but in the long run it would be a good idea to do a repaste and maybe consider new pads. I switched mine for 0.5mm high conductivity pads instead of the quite thick stock low conductivity pads and used IC7 also for good conductivity and since my repaste my temps do not push 80oC and they are all within 1-1.5oC of each other now (see my IC7 stress test screenshot also in my signature)

 

Actually these are temps that just repasted an hour ago, cleaned and all, and this is my third repaste job (Owned laptop from May 2010). My thermal pads are a wreck from what I saw when repasting (the blue one on the top of the GPU), so I was wondering if MemIO would be the VRAM? And what thickness would be the thermal pads?

 

You just answered your own question. Officially you should not reuse any pad. Most people will as long as it is clean, free of any dust/dirt and obstruction and completely covers the VRAM.

Do not even think about stressing it until you can either make sure they are fully conducting or replace them.

If your results are not prooving as you expected this may be normal but might be an idea to try a thick TIM like IC7 or MX.

 

So it is the thermal pad...Damn, got to find a good place to buy one, very hard when you're in the Philippines.

 

As long as the pads are covering the VRAM then you should be ok but if they are dislodged go back in and fix it. If you are going to do something properly do it right the first time fella

Failing to prepare is preparing to Fail!

New pads. IC7. and start again.

 

What size & thickness would you recommend on the thermal pads? Cause ordering internationally isn't cheap and I would like to order the right one instead of repeating.

 

Just to be safe, i would use 1mm pads instead of 0.5mm, my 0.5mm pads are making contact but if the gap was even a tiny bit wider they wouldn't be. Two stripes of 10mmx150mm will do the trick but you'll have to cut them to the right size. Don't get 30mmx30mm pads they aren't long enough, the pads on the vRam are probably around 5 cm long but don't take my word for it, i didn't measure them when i changed my pads.

 

You should be able to get them cheap from Ebay international that is where I picked mine up from fella.

I used 0.5 and the heatsink sat flush for me with minimal clearance and gave me very good results but 1.0mm is fine try to go for as high thermal conductivity as you can. Mine where 7.0W/mK.

 

Thanks! Now to go order the stuff!

 

Oh, don't forget there are three small pads on other components as well, though i'm not sure they are really needed but just to be safe...

 

Dallers,

What are the words used to search and find these Pads??
Or can you show me a ebay posting of one.

Thanks...

 

Hrogi, if you are in the US, i would get the pads from FrozenCPU, they have a nice selection and the prices are decent too. You could also search for the same pads on ebay...

Here are the pads i ordered: http://www.frozencpu.com/products/1...ermal_Conductivity_60_WmK.html?tl=g8c487s1292

Truth be told, i ordered both 0.5mm and 1 mm pads in case the 0.5mm pads would be too thin. I'll be disassembling for other reasons than GPU repaste soon so i'll check back on the contact between my 0.5mm pads and the GDDR5 chips but i expect i would have fried them a while back if the contact was improper.

 

tijo, is one of those enough for both sides of the GPU's VRAM? Like cutting it in half?

 

Nope, you'll need two. When i said 5cm it was a rough estimate and it's a bit large as well. I kept one of the old pads for measurement purposes, i could always measure it when i get back home. It won't be spot on but it should give a good estimate of the actual size if you can order them custom cut from somewhere.

 

GPU Thermal Pads

I used two strips of 10CMx2CMx0.5MM and I hadabout 3CM left after applying them making sure the VRAM was entirely covered and smooth to conduct with the heatsink the rest I used to cover the memory controllers. If you are worried stick with 1mm thickness it stretches anyway just be careful when peeling the sticky tape off.

Mine cost me no more than 7GBP delivered or about $15 but as you said your in the Philippines so go onto Ebay.Com and search for the cheapest worldwide reliable seller.

 

I'd like to point out that i made a mistake, i ordered 15mmx150mm pads, i will change the link i posted. The original pad i kept is 55mmx15mm, i just measured it. 10mm wide pads should be fine though, the asus pads are roughly 5mm larger than the vRAM chips and they will spread under pressure.

 

Hello Tijo, you mentioned that you had ordered the size 15mm x 150mm for the G73JH thermal pad. Does that cover all of the area that needs to be covered in the G73JH when you have changed yours?

Yiddo got 2 strips of 100mm x 20mm thermal pads and that's about 4000 mm2 compared to yours which is 2250 mm2. Though Yiddo mentioned he had about 3cm excess and that might be an excess of 600 mm2 if I am not mistaken so he might have used a total of 3400 mm2.

I just want to make sure so that I'd be able to minimize the cost when I'm about to get my new thermal pads.

Another thing is that I've managed to find the 12.0W/mK thermal pads from Ebay and it's quite pricey but it was mentioned in there that it is reusable. Upon searching a little bit on Google, I've managed to find another one which is 17.0W/mK from mxm-upgrade but I'm not sure if it's reusable though it costs less that the 12.0W/mK thermal pads.

Anyone from you guys have an idea on that 17.0W/mK thermal pads from mxm-upgrade? I'm torn between the two pads

 

I used two of those 15x150mm pads, one for each row of VRAM chips. Also, i had to cut them to the right size.

 

Your calculations quite astonishingly do sound about right lol

But I did not skimp and made sure that the pad covered the entire VRAM modules and then some so I probably did use more than Tijo if he just intended to get the job done.

The W/mk you are quoting is a very high conductivity and without doubt will be quite expensive the stock pads are probably around 4W/mk and do the job and if I remember rightly I picked up 7W/mk. The VRAM does not get anywhere near as hot as people think and nowhere near enough to cause any damage as long as there is contact to the heatsink.

 

Thanks for clearing out tijo

Thanks too Yiddo for your insights!

I'll post my results here when I'll be doing my thermal pad swap. For now, I'm just waiting for my ArctiClean to arrive then I'd be repasting with ICD 7. I'd check first if my stock thermal pads would still do its job after the repaste =)

 

my thermal pads start to melt so I just clean that excess.It's strange that they start to melt because my laptop never overheat.

 

Woah! That does not look good at all! Thermal Pads will not melt unless they are pushed way above 100oC.

Are you sure that is not thermal compound? It does look like it to me.

Those do not look like thermal pads, are they stock or your own brand? If you bought them I dont think they sold you the right item. Get some new ones pronto!

 

How would he suppose to remove those if ever? Isn't ESD or short circuit an issue to be considered when removing those kind of pads? I'm just curious as for those who used thermal pastes in their chips instead of thermal pads

 

If those are pads they are definetely not thermal pads as they do not melt unless put through extreme heat and I cannot believe they would bubble like that, they look like plastic pads. But you will have serious problems removing it if it is melted plastic, I still think it looks like large blobs of compound. @ Fantomasz Please confirm lol

Compound used should only be non conductive as well so ESD should not be an option, although conductive compounds are still about it really is not worth the risk. The problem is not normally the compound instead of the pad it is the heatsink, Asus attempts at making suitable heatsinks for their models if the JH is anything to go by was diabolical. Thermal pads are an easy option to solve the crap heatsink problem.

 

I think the guy who repasted, had used an chewing gum instead of thermal pads lol.

 

This pic looks strange. Is your fan working?

 

I don't know what this is but the color (blue) is same like these thermal pads.
It feel like buble gum and was very easy to remove with wood toothpick.
Fans working and laptop never overheating.I check temp all the time.



At the same time I had random problem with my screem.Sometimes screen won't turn over so maybe this was related? I remove excess,install fresh W7 and new drivers and no problems now.So don't know what cause my screen problem,melted pads or drivers.
