Clevo D901C, 10c drop after applying arctic silver 5

Unbelievable, I applied some arctic silver 5 today on the CPU, GPUs, Southbridge and nothbridge...

I followed Arctic cooling's website advice and applied a tiny quantity of AS 5 and the result was unbelievable, around 8c less for the GPUs, 10c less for the cpu. The hardest bit was applying the paste on the south and northbridge (under the keyboard) but at the end the keyboard felt cooler

My D901C was supposed to have AS 5 applied from factory , the thermal paste it came with looked like AS 5, felt like AS 5 but was definitely not AS 5

 

That's a pretty big difference - it could very well be that it came with AS-5 applied, just not applied very well. If there's too much put on, or it's not put on carefully enough, then it won't do it's job correctly.

 

You're right Shyster, there was a lot of paste applied... that might be the reason for the higher temps. The CPU and GPUs were completely covered of paste.

 

I vaguely recall one NBR member (I think it may have been zfactor, but I can't remember for sure) about a year or so ago who got - I believe - one of the NP579x series (probably NP5791) that had the thermal paste just glopped onto the CPU - like about a tablespoon-full worth - and when he cleaned it off and applied it correctly the system ran much, much cooler.

 

My fans are now running at very low speed, can't hear them anymore, I even had to check if I didn't forget to re-connect them.
Runs cooler and much quieter... can't be more happy

 

that sounds great! i've always used AS5 for desktop builds and i'm very satisfied with it. hopefully xoticpc applied real AS5 on my Sager

 

What are your temps now? idle and under load if possible.

vasvas, i m very interested about your technique and skill, i want to apply AS too in my D901c, can you explain more about northbridge and GPUs, cause northbridge seems hard to access because of keyboard...about GPUs is there thermal paste from nvivia or not ? I wonder if there is a risk to change it (GPUs) ?

 

LOAD temps are what matters. Game a bit , and see what the max temps are then.

 

I never applied as5 to my d901c, but my sager 5793 had thermal past just oozing all over the place on the gpu. Reapplying it myself most certainly improved thermal temps.

 

Supposedly my laptop also came with AS5 also, where did you get it from? if you don't mind me asking.

 

I got the laptop from Kobalt in the UK.

 

Just over 60c for the cpu after playing crysis for an hour and around 64c for the GPUs...

 

Less than 70C for the GPUs is impossible for me unless i put fan on high speed. I have exactly same machine as u. If i dont get to hight speed while gaming GPUs temp goes from 70 to 75/77 depending on game...Otherwise with high speed fans i stays between 55 to 60

 

Hi vasvas

If you bought your D901C/Comanche SLI from us then it will definately have AS5 on the CPU as that's all we use.

We run 4 Primes and loop 3DMark06 simultaneously overnight before shipping and if the temps are too high we won't send the laptop out. Same with the GPUs but we don't take the chipset HS off to apply paste as what's on there is fine.

 

Ok, so you did just what says on arctic silvers website? cause I have seen a lot of people rubbing the hole core with paste - but that will actually make it hotter? Hmmm . How do you do it with the gpus?
I am going to buy a clevo d901c, but with only one 9800m gtx - could you make a video on How to do it thi right way?

 

Actually I would also like some instructions on applying new AS5 or paste to my CPU/GPU and Northbridge/Southbridge

Actually what is the Northbridge/Southbridge ?? LOL

How do you apply the paste to your GPU as well?

Thanks!

I also hear

is better than AS5??

 

Newer paste of Arctic Cooling "MX2" is much better than old AS5

 

Better, how? has anyone tested it yet ?

 

yes i have test MX2 and temp are little lower than AS5 but MX2 is much better for GPUs and you dont have to change it after few monts you can see in Google Arctic Cooling MX2 compare to Arctic Cooling Arctic Silver 5 and you will see why is better

 

mx2 is a great paste imo not really better or worse for temps. let me explain. with as5 i notice a much more steady slow rise and decline in temps. with mx2 its a much faster response so it will jump to a higher temp but stay there then go up again. with as5 you see it going up and down more steady, hard to explain fully.

but the main difference for use on chips like gpu's and the southbridge's is mx2 is non conductive, and even though as5 says its non conductive i have personally tested it with a meter and can tell you it for sure does conduct, while its a very small amount it still imo can make contact between 2 traces. mx2 you could literally smear over the gpu and be fine with as5 you need to make sure not to put to much on or get it on the surface mounted stuff on the gpu..

when applying as5 it need to be thinner than mx2. as5 should have a coat that barely covers the die super thin. and do spread it on a cpu that has a raw die you want to cover the whole die. on a desktop cpu that has a heat spreader you dont do it that way you use just a dab and let the heatsink spread it. but you want to cover the whole die on the notebook cpu's

they both perform about equal in most cases excpet for the overall way the paste reacts to heat..

 

Hi,

One of my GPU's is running @ 65c idle while the other sits nice @ 41 with full fan and I also think the cards ram is overheating.. on full load the card will will go to near 90c. I have removed the heatsinks and fans and noticed that both my GPU's have no paste or thermal pad but the ram chips have thermal pads..

Im going to apply paste to the GPU's later this week. my question is, Can I also just remove the thermal pads and use paste and on the ram chips or does the ram chips have to use pads?

Thanks
Bracken

 

yes video cards dosnt have paste not on the chip but on the heatsink and little like metal pads (but not metal) that make contact with the chip if you want you can remove this and install paste

 

be careful doing that. most of the time the reason they use thermal pads is because the gap is to thick for paste, if its thicker than like a sheet of paper do not remove the thermal pads to use paste

 

Thermal paste is fine (even good) on the gpu dies, but do not remove the pads on the ram chips.

 

as I said in the 98700m gtx thread, here is my opinion (I copy & paste):

I have problems with the GPU temps and I can't do any kind of overclock on my 9800m gtx.
well... yesterday, I was playing only a little time with 'Dead Space' game and the GPU temp got 80ºC (176ºF).

today I changed the thermal compound 'Artic Silver 5' by 'Artic Cooling MX-2'.
and now, I have been playing for a long time with the same game and the temp get max 74ºC (165ºF).

I think that -6ºC is a very good temperature difference with respect to the other compound AS5. even playing much longer with the MX-2 than the AS5 compound. and even I think that the compond needs about some days or two weeks for better work and performance.



so I prefer MX-2.


greetings
(sorry my bad english)

 

Does anyone know how hot the Ram Chips go on 8800m cards? is there anyway to check ?

My whole system was unstable and very slow..so I took off the heat sinks and I noticed the thermal pads where very badly placed and did not cover all the ram chips. I corrected this and the system is now stable and fast.. but as I said, one of the gpu's is going very hot (97c in crysis)

I cant believe there was no thermal pad or paste on the gpu, guess I was unlucky.. strange how one of the cards stays cool tho.

I just about to head into town and pick up themal paste for the gpu's..should I worry about the ram chips? or do they not go hot enough ? appears very stable and fast after re-seating the pads. cant help but worry


Thanks
