IC7 Re-paste on 2670QM & 6990m Full Load Temps

This will be my last post on thermal compound......lol I hope. I will be picking up IC7 today and repasting my CPU (temp on full load with AS5 is 85-86 C). How is this properly applied? I've heard the pea method but I notice the CPU is rectangle shape, will this cover it properly or should the line method be used? Would like to do a one shot, one kill type deal on this.

Also with the 6990m it looks like my full load temp is 84-85 C with AS5. Is this a good full load temp?

Idle for the CPU is 38-39 and GPU is 40.

Thanks in advance.

 

How are you testing it? Mine idles around the same mid 30's for the CPU and GPU and with a Furmark full burn in test with POST and 8xAA 100% load I see around 87oC highest temp MEM(IO) after 10 minutes and that is with ICD.

Gaming I normally see the highest temp to be 77oC full load after 30 minutes of gaming. Remember it will differ depending on the ambient temperature. I always use ICD because it is thick and easy to apply and in comparison to different TIM's it has always yielded the best results for me.

 

As5 needs time to cure for about 200 hours before you see the lowest temps. 200 hours is off the top of my head.

200 hours is correct to reach optimal performance however the difference should be minimal. ICD only needs 10 minutes there is no curing time it just sets.

 

Unlike AS5, IC Diamond is recommended with the pea method (compared to surface spread). I just means you need to put a little more than expected on the die to account for the irregular shape.

Application

Those temps you posted with AS5 look great though, so I wouldn't even bother repasting, honestly.

 

Maybe I'm just too anxious........I'll hold off (would rather not re-paste either, though it was a good learning experience) and see what the 200 hours bring....I'm prob at 25 right now. I will use Furmark this afternoon and check the results....I've been using 3D Mark 11 (Free Version) and CineBench (kind of in a back to back fashion).
Thanks for all the help and info!

 

I would highly recommend not using Furmark as a representation of well... anything. It places an unrealistic load on the GPU (hence why it warns that it may even fry your GPU when you start it) and the temps are not representative of what you'll ever see in real world usage. I'd say you're much better of sticking to conventional benchmark tools like 3DMark rather than stress testing.

 

I appreciate the warning; I was doing some research and read a few remarks that said pretty much the same thing on Furmark....I was reading that the only way to really tell is to play a game. For some reason I'm abnormaly worried about the CPU temp. I will keep things as they are until I see 90's and then I'll start to worry again. I kind of feel bad for people who buy Asus or other gaming laptops with similiar hardware and are un able to do re-pastes unless they void the warranty.

 

I found I'm getting lower idle temperatures after some full loads with the ICD compound. At first GPU was 50C idle and now after a day, it is 40-42C.

 

I've had IC Diamond on for a day, and played Crysis 2 at Ultra for around 2-3 hours.

HWMonitor showed temps peaked at 67C for CPU and 87C for GPU (at 740/960 OC).

I idle at 32-36C for CPU and 35-40C for GPU.

 

Thanks for the replies....I finally played Skyrim last night with the AS5 paste...After 30-45 min of playing on Ultra, my CPU peaked at 72C (though I dont think it ever hit 100% utilization) and GPU at 84C (at 100% utilization).

Though in using HWMonitor...my 4th GPU temp hit 90C...the first was 84C...second 82C and third 81C......would 84C be the correct readout?

 

Wow... Skyrim was stressed to 100% on the 6990M? Interesting. Do you have any high res mods or anything installed? Does it play on maximum settings without lag?

 

They are good temps pretty much spot on considering your using a smaller model those temps sounds about right, my GPU is very similiar to your temps using furmark while gaming I normally see low 80's. My CPU never reaches 70oC even with prime low 60's but again different cooling and ambient temps make the difference.

 

According to HWMonitor my 6990M did reach 100% utilization at one point in the game. I do not have any mods installed as of yet. Every setting possible is set to its highest on the game through the settings menu. That was the default on start up set by the game. And I'm happy to report that there was not any lag or slowing down while I played.

Tonight I will hook it up to my 46in Samsung LCD TV and see how it goes...I will try and take a pic of the setup and post it. It is a beautiful TV (looks Plasma but its an LCD).

 

Thanks...since I never have pasted before and in using AS5 (I had it laying around(think I paid $3 for it through some sale) I was hopeing I wouldnt have to redo it or apply different stuff. My apt is around 74 degrees and I had the laptop set on my bar (good clearence and a cool surface). For future reference in monitoring the temps, at what degree C would you consider a repaste needing to be done on either CPU or GPU?

 

Clevo have very good cooling from what I have seen out of all my gaming laptops. The unwritten rule says to keep your temps below 100oC for the GPU and 90oC for the CPU those are pretty much a safety precaution to prevent damage and prolong the life of the hardware.

Personally I am only happy with a good 20oC clearance from the TJMax so I like to think anything below 90oC for the GPU and 80oC for the CPU is a sweet spot.

 

Is there any benefit to using IC Diamond 24 as opposed to IC7?

 

That is just the amount measured in carots nothing to do with the compound itself its all the same. 7 should be enough for around 4-5 applications of around 3-5mm blobs.

 

I guess I need a repaste then, mine reaches 97C (104.5C on Shader) just after a few minutes of Furmark (got AC MX-4 factory pasted atm)..
Never gets that hot while gaming tho, seen up to around 87 after a few hours of BF3.

There's no reason to repaste. This comes up a lot in the forums- but please don't use Furmark as a tool to check temperatures. It is not indicative of your cooling or thermal paste quality. As you noted, even Battlefield 3 doesn't hit those temperatures when it should be loading the laptop. Clevo does not recommend using Furmark, nor do any other resellers.

There's a reason it warns you when you start it that it can fry your GPU.

 

True Furmark does push the GPU way beyond what it is made to be able to handle and the burn in test does exactly what it says on the tin burns the hell out of the card and makes every part of it push till its eyes bleed.

However it is a good facility if you intend to overclock and see how stable to can get your card by applying a higher quality TIM correctly. My temps above that I mentioned 87oC is with Extreme burn in selected and everything maxed out so 104.5oC on the shader is hot. If you feel confident to repaste with ICD you should yield much better results maybe not the first time round and maybe not a huge different but you could replace that with 94.5oC.

 

for starters what are your ambient temps guys?

im getting 80c max for my 2670 and 91c max for my 6990m

does worry me quite abit i tried repasting ic7 a few times.
ambient temps are around 28-31, summer down under

 

^^^

Your CPU temps are too high try repasting. Your GPU is ok..

 

My ambient temp is around 21 C.
Are you getting those temps while gaming or running Furmark? (there's a big difference)

 

I like to look at it like this:

CPU Limit: 90oC GPU Limit 100oC

CPU Ideal: Below 80oC GPU Ideal: Below 90oC

You are only a degree over the ''IMO'' what temperatures should be running, add that to your current ambient temperature and you dont need to worry.

Two options are cleaning and repasting if you are on stock paste those temps are very normal, if you tried a high quality TIM you might notice better results and quieter fans but you will notice no difference in the life of the card mobility cards run hot that is a fact.

 

Both are fine. Intel recommend maximum cooling at TJMax-10C for the i7M, or 90c. With an ambient temperature of 30c your cooling is good.

 

my 6990m shoots up to 95C shader temps 98C when i play metro 2033 maxed out with software OC (800/1050)

is this problematic? should i just play in stock clocks or get a cooler or something?

 

They are quite high, it depends what your ambient temp is where you live if its above 25oC then those temperatures are not that uncommon.

I am adamant that you could yield better results however by reapplying the thermal compound, I found that my stock paste or at least the MX4 my uk seller confirmed they applied did not cover the entire DIE.

I applied a short line of ICD across the DIE and reseated and I dropped near 20oC from max temps even more on the shaders as that seems to be our hottest section on the 6990M.

If you have had your setup for a while you could first try cleaning the fans and radiators of the heatsink but these seem to stay pretty clean. Whip the back panel off and take a look these are so easy to repaste a 2 year old could do it, it just depends if you have a warranty sticker or not most dont.

 

Yes, those are extremely high temperatures. Anything over 90-95C is in the danger zone. While it will work at those temperatures, it's definitely not good for the hardware.

 

I think OP can try undervolting, I'm currently running .200 lower than the fixed stock voltage on the 5830, 0.700 instead of 0.900. No loss in performance, decreases about 6-7 degrees

 

Just as an update, instead of repasting I ended up undervolting, droped it from:
1.1v @ stock clocks and getting 97C+ in Furmark
to:
1.05v @ 725/925MHz and getting 94C stable in Furmark

This means I'll get around 84-85C in graphic intense games
