Very HIGH temps after new thermal paste job

Today I replaced my GPUs thermal paste from stock to Arctic Mx-3.I did clean it with a paper towel and afterwards applied the layer with a thin layer of card on the metal surface.When I run FurMark the temperatures are unbearable! It might go all the way up to 100 but its getting throttled.I hear that the fan isnt sounding as quite loud.I really need help

 

When replacing the thermal compound you 'll want to make sure all the old stuff is cleaned off. Using a very high percentage isopropol alcohol is recommended or buying some of the commercial thermal compound emulsifiers/purifiers. If you don't you won't be getting a good heat transfer since the old stuff is still caked in the metal pores of the processor.

 

I retried the entire process,this time I cleaned it again and placed it as a bead.As soon as I try to run FurMark It says THROTTLING -3 (standard clocks) and as the temps get worse THROTTLING -300 naturally.

It is suggested that applying a blob of paste, then using the heatsink pressure to spread it evenly is better then the card method you used.

 

Yes I did exactly what he said,and placed it as a piece of bead.I am going to take a few photos I suppose now.

 

Here is how it looks like every single time.

 

Doesn't look like you have much paste on there.

 

Nope..fail fail and fail every single try.

 

This is why I paid for having the paste applied at the factory. It keeps me from messing it up with my big clumsy fingers.
It takes practice to get it right. Just be patient and don't give up.

You might also want to search around for tutorials and videos. There are several methods you can try. Some might work better for you than others.

 

I think you should try to adding a bit more TIM because it looks like there are portions that didn't get covered. I pointed out where there wasn't any paste and did a rectangular overlay of the chip size on the heat sink to illustrate this. Adding a little bit more and pressing down on the heat sink to spread it may help. It takes ten minutes to reapply so it's worth a try. I did a comparison of three different TIMS and go over the application of them if this helps.

 

First, the TIM isnt enough. You need a pea sized blob in the gpu center, like 0,5mm x 0,5mm.

But before doing that, cleaning with a paper towel without using an alcohol based solution doesnt help either. You cant just wipe out the old paste.
Try to get isopropyl alcohol, or rubbing alcohol at least 95%.

Use lynth cloth or similar, just not standard paper/kitched paper. Clean it with above solvents, then be sure you get a nice big blob in the center, and put everything back on.

 

Also, if you remove the heatsink you have to redo it all. You can't lift it to check if the paste is applied properly. You probably know this, but it could help.

 

Yeah, you aren't using enough TIM.

 

i have attempted re pasting for about 3 times in a row now,the old paste should be long gone,My arctic tube has a little left now,there are indicators like you would see on syringes 10mg 20mg so firing off from one indicator to the next should suffice? the guy who has presented us the guide had so little on his die that I thought a small amount would suffice.Odd thing is whenever I run furmark it starts slightly throttled and by the end of the second minute I shut down manually as it reaches around 90C which I deem dangerous.I am going to give it one more go if you guys can confirm firing off from one indicator to the next one will be enough.And what I noticed is that the main portion of the paste is not on the die itself but is pushed away further to the sides of the chip.

Oh and it is my first attempt at repasting and I do not regret learning by trial and error unless it damages the GPU but I kinda miss that stock paste now.I came home with a new ssd and a paste,I guess I was just
itching today.Ambition in overlooking is bad

 

Are you tightening the screws in number order? If you simply tighten all the way on on side then that could cause what you are seeing.

 

I do it as the numbers indicate which looks like an X

 

Oh, strange. It does look as if the pressure is uneven from the picture. Obviously the paste is there to fill the imperfections in the surface of the die and heatsink, so you do need decent coverage. Maybe try not tightening them all the way at once, but a little at a time which should spread it evenly. Must be frustrating.

 

Ah I give up it simply is not happening.

 

Seems like the problem was maybe furmark based.Out of frustration,I thought I'd find a method myself.I took a cotton swab and fixed the positioning of the remaining TIM on the GPU..after that I took the TIM that was extra and with the cotton swab put some on the heatsink aswell,that covers the same area as the GPU die does.I know its stupid and retarded and I dont know crap about repasting.Oddly it works.Approx. 1 hour of BF3,standard clocks,670M,Max temperature was 76C.Thats not too bad is it?

 

I have always used the line method for every single laptop GPU and CPU and have never had any problems. I used it for my recent GTX680M too.

 

I use the line method with a rectangular core like the Ivey Bridge, but for a square, I think either line method going diagonal or dot is best, though I think dot is best. With ICD7, I put very little on the heatsink itself and rub it in, thin film. And a dot on the core.

 

I dont think I have ever seen it recommended but I have always used a plastic or latex glove and even spread a super fine layer of compound evenly over the entire chip.

 

You don't get air issue with spread method?

 

This was before the era of the carbon based thermal compounds but I had excellent results. I'm not going to recommend going against the instructions of the manufacturers though. Also this was always with CPUs and those heatsinks apply massive amounts of pressure.

 

You need proper paste, try GELID GC Extreme.

Spreading is actually recommended for uncapped GPU dies.

Make sure to align the heatsinks well before tightening.

That should get you all set. I also had mad temps with Arctic SIlver 5 (up to 100)

 

im with bn880... i had IC diamond on my cpu and gpu and replaced it with gelid. my CPU dropped 5C and my GPU dropped 3C. its simply the best compound ive ever used

 

i disagree, if you had your paste put on at the factory it will not be as good as when you put it on yourself.

 

Definitely looks like too little paste. Despite everyone saying there's too much usually, you're better off having a little extra, especially with the newer and more exotic pastes because they are less likely to be detrimental to the heat transfer even if thicker. You definitely don't want too little. On the CPU you definitely want to do a line, make it 3mm wide by about 8mm long. On the GPU about a 4-5mm diameter bead will be fine. I even do a small X actually on the square dies.

 

Particularly now that fewer and fewer pastes are electrically conductive. That was always a major worry for people applying paste since that used to be the "standard".

But it seems that op has solved his problem some how, so I suppose That is the end of it!

 

+1 for Gelid. Had ICD7 before, temps would hit 90c in furmark in less than 5 minutes. With Gelid I very rarely touch 80c.
