M17x R2 - Nvdia GTX 680m Temps

So,

After all that OC'ing and benching i repasted like a 100 times and now i have NO idea what temp i should have on stock clocks after (something easily accessible) benching 2 round of 3DMark11

When i play Bf3 for like 30 minutes, i get ~80 degrees temps (<---GPU Bios unlocked, no volt mod)

I am interested to see how much all our R2's with a 680m differ in temps amongst one another.
Lets get some temps here.

Make a screenie and inform use of your ambient temps and tells us of you used a cooler stand (or just use an eraser to elevate the back) or just have it flat on table

Lets have some fun, lets see who can keep an cool (alien) head.

If I remember correctly, 75-78C was normal for the 680M while benching/gaming.

Make sure you're not blocking the intake vents. And try using something to prop it up to allow for better airflow. Also, maybe try another thermal paste (i.e. IC Diamond). It shouldn't be that hot with some good thermal paste like IC Diamond. The most you should see is like 72C after a repaste.

Do you have the correct vBIOS and drivers?

 

I know you asked for r2 temps, but FWIW my 4GB 680M in my r3 overclocked to 915MHz core and 2250MHz memory doesn't go any higher than 66C whilst playing Bioshock Infinite. It's stable, too, no crashes. Before overclocking, max temp was 64C.

I'm using a CoolerMaster cooling stand, a modified vBIOS with over-volting (svl7's vBIOS for 4GB Clevo cards on Tech Inferno), and when I upgraded to my 680M I re-used my heatsink for my 6970M and used IC Diamond 7 paste.

Hi man,

Thanks for your input!
I am not sure if the heatsink for the R3 was improved...i think so.
I was indeed asking specificly for the R2 because the heatsink of the R2 was not really designed for 100W cards;.

Nice temps though (y)

@J.Dre
I have some idea on how to paste
I still think my heatsink is a bit warped so i order another one just to see what the difference is.
From what i can remember, my card didn't go above 80 degrees not so long ago but no matter what i do, it still goes above 80.
I just thought of something so simple...i just put my 0,5mm Fujipoly thermal pad between the heatsink and Die and....it actually remains cooler for a longer periode...but it does move up around 82...

So for the record:
Playing Bf3 for an hour, 79 degrees.
Stock settings and volt
Tested with Cooler Master: NOTEPAL U3 and Zalman NC3000-U

 

I'm having the same problem. I installed the GTX 680M in my M17X R2 and temps are still in in the 80's. I don't know what wrong. When you put 0.5mm Fujipoly thermal pad between heatsink and die did you still put thermal paste still?

 

The fan profile is also a bit different than the R4, which is what the 680M was made for.

80C is nothing to worry about as a maximum temperature. Just keep an eye on it and re-paste regularly.

 

Actually temps are around 87-88C degrees to be more specific.

What tim are you using? thermal pads?

 

Using the 0.5 and 1mm thermal pads and AS5 line method.

Try a diffrent timp and see what are the temps then, clean from dust...they put 2x 7970m and still made it to work

 

I see. What paste brand do you suggest? Also isn't the 7970M a 75W card?

Everyone here that tested...coolaboratory liquid pro is the best there is as long as you repastet carrefully and do not touch any aluminium.

 

IC Diamond provides the best overall results for GPU's. Arctic Silver is cheap and doesn't work well. Liquid Ultra works best for CPU's. It was shown that it does not help GPU's any better than IC Diamond.

For GPU's, you do not want to use the line method. That method is suggested for mobile CPU's. GPU's need the dot or cross-method. The dot-method is most commonly used because it's easy and usually uses less paste. From my experience, I've learned that the cross-method actually spreads more evenly among the GPU surface. Does it make much of a difference? Negligible at best. That's just my preferred method.

 

This temps are definitely on the high side.
My 680m with crysis 2 and 3 will not go above 70c after playing for a few hours
Those 80+ temps would have me worried.

Some suggestions :
* use icd7
* your fans should be quite loud when gaming
* use hwinfo to control fans if fans are quiet when gaming

 

I might have found the problem. I used thicker thermal pads on one side of VRAM's that causes the warped heatsink issue in which the heat sink isn't pressing even on GPU die. I am using HWINFO to max out fans but doesn't seem to be doing much so I am concluding it is because GPU isn't pressing flat against heatsink. I will try IC7 Diamond as well. Thank you.

Are you using the M17X R2?

I have the m17xr2 with 7970m and it has very similar temps to what I posted with the 680m with clevo.
The clevo has very quiet fans and keeps temps down.

The Alienware is very noisy fans especially on high ramp speed. From memory the alienware ec has 3 speed profiles. Low medium and high. If you are using hwinfo at max speed and temps not going down then something else is a miss. As you posted the copper cooler is not flush with the gpu. Only use one strip for thermal pads for vram. I did not put vram pad on the back side for the additional 2GB vram modules (I have 4GB card)

Check everything looks right before reassembling.
Good luck.

 

Thanks I shall keep you posted.

When you say cross method, do you mean like pasting it like an "X" mark? Or like a diagonal line?

Well folks I repasted using cross method and fixed the heatsink from the warping issue. Apparently I was wrong in using thick pads for the VRAMS and voltage indicators so I used 0.5mm pads on those instead of 1mm and I used the 1mm pads on the two backside VRAMS and my temps are a huge improvement now. Before I was getting 44C idle and 92C load. Now it is 27C idle and 71C load. This is all without using a laptop cooler. I will do test with my modded laptop cooler and will order IC7 Diamond to see if I can get it better.

I have also 1mm and 0,5 mm thermal pads...I wanted to put 1mm on the vrams...cand you show where did u put the 1 mmm?

 

That's excellent news.
Maybe a short synopsis or guide of your pasting methodology and thermal pad placement would help others achieve low temps.

 

When it comes to to paste it seems peeps in here is sponsored by ICD7, blind for altenatives. (your loss)
Ive used Gelid GC extreme and ICD7, and I dont use ICD7 anymore.

Gelid extreeme is most likely better than ICD7 in the two most important ways. Most objective tests show this if you read up on bigger newer tests. It has slightly better heat transfer and it also has way better spread-ability, hence gives you better chance of getting good contact. For all serious tests ive read, the GC extreme is the choice when not choosing the liquid metal.

Only better (for me at least) is the Heatspring that i run on one of my GPU's, and it runs at least 3-4 degrees cooler than the Gelid extreme that I curently use on the primary card for comparing when running fullscreen crossfire as in BF4 over longer time.

The 7970M is 100W card.

 

I would suggest Arctic Cooling MX-4..heard good things about it... I'm actually repasting my CPU today with it..

 

Sure I will do a quick write up. What I will say is that using 0.5mm pads on VRAMS on front side does help the heatsink to press down more evenly and firmly on GPU die for better cooling. 1mm pads were too thick for the VRAMS which caused the heatsink to be slightly raised on one side. No wonder my temperatures would skyrocket to 90C+. I forgot to mention I did sand down (from copper shim mod kit) the heatsink copper and the GPU die which helped the thermal paste to spread more evenly and keep even pressure across GPU die when mounting heatsink. I did a quick 20 min test with my modified cooling gear where I used four desktop fans assembled below my U2 notebook cooler and also a heat extractor in the events on medium setting and I'm getting 66-67C degrees Celcius on GPU die now when playing Tomb Raider on Ultra. Can't wait to try all your suggestions to keep it cooler. Will post pics. Thanks again you all. Hope more R2 users who use the 680M can chime in on their temperatures.

I will post pics when I open it up again. Pretty much I used 0.5mm thermal pads on voltage indicators and the two VRAMS on front side. For the two backside VRAMS I used 1mm pads so that it would make good contact with top surface of the GPU fan. All in all you just want to make sure that the heatsink is evenly pressing down on the GPU die. You don't want to see one part or corner of heatsink raised up or else it will drastically hinder heat dissipation. Can't believe it took me a month of trial and error.
