why you should re-apply thermal paste to you gpu...

these are a few pics i took when i removed the 8700 of the ridiculous amount of thermal paste on the gpu and this is not all of it the rest was cleaned off with alcohol and scraped from the cracks as best i could around the die.. this is just from what was between the heatsink and the die it was like a thick solid layer.. and no it was not a thermal pad.. it was actual paste applied this thick

ridiculous this is like almost the whole tube they send with the new gpu and you dont need more than a small drop on the die of that stuff.. not the best pica but you get the idea..

 

my understanding sager using artic silver5 on NP9262 on the laptops and ships out the paste that comes with laptop from the factory.

 

You got the the laptop from RJTech right? maybe they were feeling generous

 

nope 8700 and it came from xotic drop shipped from sager.. and no this in 150% not arctic silver.. trust me i know what as5 looks like ive used it for years. this was the same stuff that came with the 8800gtx in the box and that IS NOT AS5 either..i still have a bit of that left i could maybe see if i can get a good pic of it.. but i assure you it is not as5.

there was enough on the 8700 to honestly prob coat 5 or 6 at least gpu dies.. trust me it was ridiculous

 

Yea, I meant to say laptop. I think something`s wrong with my brain today,I keep goofing up.
So the one that came from Xotic is NOT AS5 ? that`s not good

 

again THIS WAS DROP SHIPPED from sager. and from what i understand they use as5 on the cpu.. not the gpu.. imo this may be a type of stuff similar to shin if you know what that is. at least thats what it resembles.. but i doubt its real shin-etsu

 

Zfactor, you should have set your camera to macro or close up to get the subject in focus.

 

well here you go a white piece of paper with about HALF OF THE COMPOUND THAT CAME OFF THE GPU DIE!!!!! and a small smear of as5 (about DOUBLE what you should actually use for the gpu die so you can see the difference)

so you can clearly see this is NOT AS5!!!

 

AND THE OTHER HALF OF IT STILL ON THE piece of plastic :

 

I got this thing came with my 5793 package, looks like AS5 to me, can someone confirm it?
it said "GFC-M7" on it, P/N:6-47-M57R8-010

 

I´ve applied AS5 both on CPU and GPU... and my factory thermal paste looks equal yours...

Becase mine is unbranded(Style-Note) and not a Sager one, I did not bother myself... only Sager ones was supose to came with AS5 from factory...

I guess I was wrong...

 

Hummm it looks suspicious to me...

What is her colour?

 

not as5 as far as i can tell looks like the same stuff that came with my 8800 looks to light grey imo..

i only apply real as5 or i use mx2 as well..

 

looks like AS5 imo, I applied AS5 on my thinkpad before, but I am not sure what it is at this point

 

good question i dont know why they would have sent it. from your pic it doesn't look like as5 but hard to tell from that pic. i can say if i had it here i could tell for sure.. i have around 2 dozen or so tubes here lol and i use it all the time for customers..again my whole point here though is to check the gpu.. it was insane the amount of paste BETWEEN the die and the heatsink

 

z the max temperature of my system was 54C @ 2.9Ghz, do you think I should re-apply AS5?
edit: what's your GPU temp before/after applied AS5?

 

good question not sure.. ill check when i get home for you.

 

So you`re saying Sager DID NOT apply AS5 on the GPU as they were supose to or what? Since you only got the GPU from Sager...

 

not sure if they are supposed to apply as5 to the gpu or not honeslty i thought it was only on the cpu. i can for sure 100% this was NOT as5 on the gpu. so if they were supposed to apply it then they did not. i am not sure if sager does it directly or not on the gpu.

my main point was to remove the huge amount of stuff applied (if it was done that way) and re-apply it right, this was the point of the thread.. not if it should be as5 or not

 

The thing is that Sager applies AS5 , but it`s an option for pre-built systems so, it may not be for parts only.
I don`t want to jump the gun, my 7950GTX COULD NOT RUN as cool as max 65C if there wasn`t AS5 on it, especially without a notebook cooler , as I`m running it.

 

my original 8700 came pre-installed from sager in the notebook. so they either installed it or it came from clevo this way. i did not install the 8700.

 

So ,whatever was on your 8700M GT was NOT AS5 ... and Sager said AS5 is there by default...
This is just unbelieveble...

 

i guess.. they never specified anywhere that i can see that as5 is applied to the gpu?? i know they say its on the cpu. have you seen somewhere it says it was supposed to be applied to the gpu..

i can say another reason i know for sure this is not as5 is as5 is conductive. this gunk was smeared all over the surrounding parts of the gpu die under the black plastic that is there. if this was as5 there would have been trouble from it making contact at those points..

 

its not a option on the NP9262, so I went on Chat with xotic they said for sure on the CPU, but weren't sure if the 8800gtx had artic silver???? So I called Sager tech again I stuttered they answered on the first ring, (whoah). This time they asked for my serial # no problem. He said "I would have to ask a senior tech please hold"....two minutes later "we use high quality thermal paste, comparable to artic silver all our laptops come with thermal paste from the factory and thats what we use".....

if thats the case xotic needs to update their website 5-8 dollars they charge extra is no biggie, but a free shirt would be nice....

FN+1...is your friend he said....lol....cause I asked him if 56c was to high for HDD temps he said that was normal.

 

Yes, I noticed it`s on the CPU according to the webpage. So my GTX runs natively cool compared to other GPUs...nice. I imagine that with some AS5 on it, it would run even cooler...
So the sager tech dude said it`s not AS5? bummer.
I always though my CPU temps were the highest ones in the laptop.Now I know why

 

maybe it is applied better to some gpu's than others. imo if your temps are high i would def check to see how badly it has been applied.

 

Well, they`re not high anymore, I ain`t giving them weed lol.
I`ve undervolted, but the high temps stop me from going to 2.6 Ghz
I`ll have to double check that.
I may need your guys` help on this one, I`ve never really applied AS5 on my laptop,and even though I`ve done it on others,I want to make sure it`s perfect for me.
I`m so selfish hehe

 

there are guides on how to apply the stuff on thier website arcticsilver

 

its easy to do.. as above see the web site or i can help you if you need it.

 

Lol, I know , I read them when I did it on my friend`s 1520.
I just want to know first-hand from people who noticed real life results.
I hate following written instructions,real life experience is always better.
But this will happen after my CPU upgrade in June/July.

 

so what do we have here? AS5 on cpu but something else on GPU? my GPU seems never passed 70C tho

 

The GPU is a cold hearted bastard lol.
The RU has an amazing cooling system, I`ll give you that...

 

me personally i like the method of just applying a super thin coat to the die. i actually use a piece i cut off of a small plastic bondo spreader it works great

 

Yep, same little baby tube I got... B/W don't get it on your fingers (I'm like a little kid- at least I didn't put it in my mouth. ) cause it will be there for a while.

OK, so my CPU came with as5, but does Xotic apply it to the 88gtx as well?
((((guess it doesn't matter cause it runs so dang cool, even at full load))))

 

Or your clothes (i.e., clothes that aren't supposed to look like a mechanic's work uniform) - I learned that one the hard way.

 

91% alcohol takes it right off.. even off most clothes. it dissolves almost as soon as the alcohol touches it..

 

let me clarify:

according to xotic website the NP9262 artic silver is used. Chatted with xotic pc only the CPU has arctic silver for sure, but he was not sure on the 8800gtx I had to call Sager. Xotic Pc only places the order for you from sager known as "drop ship" as if you live in california it saves in taxes... (happy customer here thats over 240 dollars for me). So I called Sager according to them they use thermal paste comparable to artic silver both on the CPU and video card and this came from a senior tech.

Maybe some Reps from Sager and Xotic should chime in here.

 

The NP9262 8800mGTX's come with thermal pads, no arctic silver there... I just had them both out 2 days ago.

 

Hummm a thermal paste comparable to AS5 but is not AS5... hummm...

Sounds like grey cheap toothpaste to me...

 

Both my CPU and GPU came with thermal pads... but my M570RU is unbranded, so I can´t confirm anything about Sager...

 

Having talked to LiveChat, they said that AS5 is applied onto the CPU, but that`s about it.So it still does not explain my high CPU temps at stock voltages...
No mention of the GPU ...

 

^^^ no offense to anyone but doesnt mean it was applied properly. when as5 is applied wrong (to thick) it can actually make temps go up rather than down from my experience..may not be your issue but def something to look at

 

well, my comp came with as5 on both cpu and gpu, but then its not from sager...It also came with a custom gfx heatsink to increase the vram cooling. (obviously the vram modules have thermal pads as theres too much of a gap for as5)

 

pics of the gfx heatsink???? possibly??

 

I'll post pics when I get time to take the bottom off

 

sweet thanks!!

 

the gpu's come with a factory thermal pad from nvidia so the resellers and sager do not tamper with it or apply their own. i have applied AS-5 on the gpu's, though.

 

no mine was NOT a thermal pad.. this was paste... trust me i know the difference. this was the same paste that was included with the 8800 card when bought by itself.. which DID NOT HAVE A THERMAL PAD on it either..

 

hopefully this weekend i'll find out what's in my 2092. i'm wondering what i have. i think i already know, but that's about to change.

 

My understanding of the use of thermal paste is as follows. The optimum cooling solution would involve a die/heat sink that make complete contact across the entire surface areas of both without any sort of paste. However, both surfaces contain nearly microscopic imperfections in the form of pits and grooves (like brush strokes) that cause gaps in the contact area. Therefore, thermal paste such as AS5 is required to fill those gaps so that both surfaces are completely smooth and contact area reaches as close to 100% as possible.

However, filling those gaps requires but a very thin layer of thermal paste. Optimally, you really only want paste to be present where the gaps exist, as the sink to die direct contact is still the most efficient means of heat transferral. That said, I've always gone with the method of applying just a very small drop (about the size of a grain of rice on a desktop processor) to the middle of the die and then smearing it around as evenly and thinly as possible using the heat sink itself, before firmly fastening the sink. What you *don't* want is to apply to much so that excess paste is squeezed out to settle around the die, as that only serves to reduce the heat dissipation around the edges of the die.

I'm no thermal engineer, but this has been my take on it for years, and it has served me well. I've gotten some decent overclocks out of processors and never had heat problems. I would also welcome any more knowledgeable insight that might provide improvements to this method.
