Chastity's Thoughts on Repasting (Read Here First)

I didnt wait either for IC7 I used Arctic Silver 5 a tube I had lying around and im very pleased with the results.

As DCX mentioned once "Its the difference between coke and pepsi" The brand name not the stuff inside.

 

Umm AS5 Vs IC7. My experience
AS5 ide 58c - 60c full 88c - 93c
IC7 ide 55c - 58c full 83c - 88c

Repaste 4 times with AS5 and these were the best results, different methods.

 

This is your experience though.

My experience is here

Everyone to their own as every repaste will be different.

Still Coke vs Pepsi. Just depends which one you like the taste of I choose Dr Pepper personally.

 

Here are a few pictures I took while doing the re-pasting

The infamous speaker connector, I found the trick to removing it is using a small flat screw driver and slowly prying between the motherboard connector and the wire connector (part that goes into the connector) placing the screw driver at the narrow ends and slowly prying it apart switch back and forth from side to side


Here is the keyboard, I think I did a pretty good job not bending it



A good picture of what the factory paste looked like


Picture of the GPU with the factory paste before cleaning.

 

Nice pictures. Top down your paste looks ok, but at an angle that is a large amount missing look how bad my CPU paste was

 

yeah it looks like it was either missing or not making contact with either the gpu or the heatsink.

I wonder if I should have checked my CPU while I was in there, but I haven't had any problems with my CPU over heating even running linepack and OCCT with the Asus Turbo boost on.

 

guys please see this . i did repaste today . So how it is . Do you think its ok please see screen shot
I used OCZ Freeze as couldn't find IC7
I haven't got much time to check it properly .
But here
idle = 58C
normal browsing + music + movie = 62-65C
Gaming (burnout paradise for 2hrs) = 83-85C
Furmark for 25min. = 86C max.

 

Damn your idle beats mine I am at 59C

 

Your temping only the GPU you need to run HWinfo32 because the MEM(IO) and shaders will be running 4-8oC hotter than the GPU itself.

Those temps are perfectly within the green zone for that card though.

See I thought this too my CPU idled around 55oC and never breached 80oC with turbo and twin turbo on. But as you can see how poorly my paste was spread im glad I did it and now im getting 45oC idle and it never goes above 68/69oC now

 

ok just checked . they are running instead 2C less compare to GPU thermal diode

i live in india and here already getting hot . right now i can guess that my room ambient temp is around 25C

 

Is that under load or Idle? Strange mine differ more the hotter it gets my max temps under full load extreme burn are normally:

DISP: 79oC
MEM: 86oC
DIODE: 78oC
SHADER: 84oC

 

Just for funzies, I ran a Furmark 1.90 on top of 11.4, with an 820/1100 overclock, and opened the bottom panel, and setup the SF-19 cooler on full blast.

Results: (Highest Temps shown)

TSS0 (DispIO): 70.0C
TSS1 (MemIO): 72.5C
TSS2 (Shader): 70.5C

Ambient of 20C

Fans Off & Underpanel open atop cooler:

TSS0 (DispIO): 78.0C
TSS1 (MemIO): 80.0C
TSS2 (Shader): 78.0C

With panel closed atop cooler with fans off:

TSS0 (DispIO): 77.0C
TSS1 (MemIO): 78.5C
TSS2 (Shader): 76.5C

 

Reading this thread i do not see the point in repasting my JH-B1.


Idles at 48c room temp ~21c
Full load at stock clocks furmark i get ~73c room temp ~21c

But it seems that the problem is with memory cooling (think the pads are not on the sink correctly)

I cannot go over 1100 mem. clock as it will just crash.

Did they use IC7 on the B1 model ?

On a cooling pad i get idle 46c and load ~72. If i remove the bottom panel and the top of the rear vents at stock i get 43-44 and load ~70.

Is the room for improvment ? A bit scared that if open her up ill just end up getting bad temp like some here. Only thing is might fix the mem overheating problem.



A nother thing is that are all the G73 copper painted inside? The B1 seems to be copper painted (removing the rear top fan cover saw that the inside was painted with copper paint) Seems like a good way to remove heat from the motherboard, CPU and GPU via the case itself.

 

It sounds like your drivers to be honest 11.2 which I use I cannot go over 1100 either without artifacts and my MEM(IO) runs at 85oC max under extreme burn mode which is miles within operating temps. Also every program and game is different when it comes to clocks some crash my driver at 1100 and some with only the slightest o/c. My core I can easily push to 900 though without any problems.

 

Core is not a problem yes. It can go over 800 no problem. Its just the mem. Ill to some better test after work to see what overheats if anything does. I use 11.4 beta driver. The 1100 mem problem has been since i got the notebook and factory drivers.

Will get some Furmark screenshots

 

Mine is the same with the beta drivers although I normally wait till the actual ones come out before updating.

1100 is pretty good though do you really need more than that or is it for testing purposes? I normally stick to 800/1000 as that is most stable for me and does not go above 72oC meaning my fans stay low. I have tested 900/1100 and that runs fine but anything above that on the mem artifacts, the memory is already quite fast for a 128bit bus.

 

Just like to test the system. I play 800/1100 all the time and the fans stay low. Only furmark is the only program that get the fans to speed up at 73C. In games i have not seen this happon yet.

As im studing thermal engineering for my masters degree so its a bad habbit to try and make cooling systems better
Thats why i am still planing on building a full copper heatsink Just waiting for a friend to borrow me a thermal infrared camera so that i can see what part of the stock heatsink heats up the most and if there is a area in the notebook that does not allow the heat to vent out correctly.

 

PM once you have please ill have one of those copper heatsinks if ones going hehe

 

well PM me too


@Chastity could post screenshot of your HWiNFO32 please

 

Will do Hope to get the thermal camera pics by the end of next week.

Here are my Furmark runs

Stock: No turbo, 700/1000 On a ZALMAN cooling pad (5v big fan) The fan makes no noise and the cooling is minimal
Room temp is 20,8C
http://i255.photobucket.com/albums/hh141/Deadboy48/Thermal.jpg

CPU stock speeds, GPU 800/1100 (its just a short run but it idles fast as i just clocked it after the first test)
http://i255.photobucket.com/albums/hh141/Deadboy48/Thermal2.jpg

These tests are form a out of the box notebook. Have no idea what paste its got as i just orderd the B1 model form the states without any custom work .

As can see the memory heats up more then the rest of the card.

Ill add some more test to this post a bit later without the cooling pad and with the bottom cover off


Edit: On a desk without a coolingpad
stock clocks. Fans speed up abit at 73C
http://i255.photobucket.com/albums/hh141/Deadboy48/Thermal3.jpg

Compared to Chastity`s temps my mem. is burning up :S

 

Should ask me these things the day when I'm running them

Anyhoo, here's a new run, no fan cooling:

 

@chastity see this screenshot . i ran furmark for 40Min. It also show my idle temp . Do you think its ok . Do i need to repaste again .

One more thing i had discussion long ago with another guy or you don't remember but Temp. shown in HDD flow can give you idea about your ambient room temp. . Is it true . 99% time my temp. remain 40C in HDD airflow where as your is just 28C

here the screenshot

 

You cannot base a repaste on Idle temps fella as you said you had just run furmark for 40 minutes and your ambient room temperature makes a big difference. I notice your from India and if I remember rightly it gets pretty humid there. Along with some of the best chicken madras and peshwari naan I have tasted

Run it again and take a screenshot of the maximum temps and post them up.

P.s your desktop is crazy messy haha tidy your room and get some gadgets!

 

if you see my screenshot you can see my gpu temp . reached 90C .

And ya here in india temp. is hot even in march . So please look at screenshot temp. both max. and min.


PS : well i have been thinking about cleaning my desktop from past 4months

 

Sorry only just woke up 90oC is fine mine reaches on the MEM(IO) 92oC and reached 102oC prior to a repaste only think about repasting if you are reaching the 98oC mark and remember that Furmark stresses the card way above normal processing requirements.

 

Those temps are fine as long as you are not crashing. Since it's humid where you live, you'll need to dust the vents more often.

 

Just did my IC7 repast and the result so far a .....just Wow.


Gone do a longer Furmark but now all my temps are at a 10C range and not like before when the GPU core was 73 and the mem at the same time was 92,5. This test is only 7 min but with out the aid from a coolingpad.

@DH48 where do you live ?

 

In europe. Estonia

 

Very nice temps im in the UK im struggling to find IC7 might need to get me some from the US. I see your running at standard clocks you should be able to handle 800/1100 very easily now and probably not even push very far into the 80's.

Could you try extreme burn please as in as that picture appears to be standard furmark settings and with AS5 I get pretty much the same as you, would like to see what IC7 does for your max temps.

Extreme Burn + Post with 8x MSAA with 800/1100 at 720P I hit MEM(IO) 88oC that is my highest temp.

 

Anybody repaste just for the heck of it? At stock clocks I'm getting 50C idle and running furmark at its most demanding settings I get 81C max. (This is on the GPU itself.) Can I expect any benefit by doing this?

Thanks.

 

81oC at extreme burn and 50oC you have more chance or raising your temps then lowering them as most after a repaste dont get that good they are what I get with standard clocks after a repaste with AS5 although my idle is 48oC. No point you risking it for a couple of degrees.

 

I'm getting 98c after only about 5 minutes of furmark, and I chicken out and close the program. At about this temp, I start to notice the 3d hitching (this happened in Crysis as well, same temps).

Also, if I try to play any sounds through windows after closing a game and the computer is still hot, I get that awful grinding noise until I shut off the computer or quickly hit "sleep"

Should I RMA? (I am not confident in risking any of my hardware during the tear down)

EDIT: Temps idle at about 63-67c, though I've seen it at 70c when idling. Room temperature is usually ~21c

 

I had the exactly the same and the horrible static noise you mention also both have been fixed by repasting for me. The static noise is debateable but seems to be a hardware problem and from my experience it came from my temps being too high and dropping them by 15oC stopped the static noise. I always got it after maxing furmark and then closing it as it cooled down screeeeeech!

You dont need to restart or hit sleep by the way the static noise lasts for only 10 seconds and then stops its very strange. Creative drivers run most stable for me with 2.54 also I have had no crashes since installing these with creative so the static could possibly have been fixed by this.

I killed furmark at 102oC before repasting but it will turn your computer off it gets too hot you might want to try the compressed air in the fan holes at the back first to shift any dust or blockages otherwise a repaste is recommended and if in warranty send it in to be done.

EDIT: Your idle temps are quite high for the ambient temp. Im at 18oC and running 49oC after a repaste 54oC before.

 

Do not know if i did it right. Added extreme mode and 8x MSAA and 1280x1024



Only diference i can spot is the low FPS.

As its late i did a short test and will do a longer one tomorrow
Strange i left the notebook off for a few hours and the paste seems better lol

When i repasted i did not wait the 10 min. Strange is i still cant go over 1100 without artifacts Core can go upto 860 get a shutdown when the power usage goes over 65W

 

1100 is my limit as well I wouldnt worry about that you should just be happy with your temps being 79oC with those settings LOL very nice looks like I need to order me some IC7.

If IC7 is anything like AS5 it takes several hours to take proper effect and mould onto the heatsink although I know you heat up IC7 before applying so dont know if its the same.

Anyone know an IC7 seller in the UK please let me know. Thanks

 

ICD7 is not like AS5 and has no required cure time.

 

Ok, so i just repasted this evening with MX-2 and here are the results:

Bios: 213
vBios Chastity's OD2
c1x GPU
Cat 11.2
Ambient T: 23C

Here's what my temps looked like before repasting after just a few minutes in furmark:

http://i255.photobucket.com/albums/hh155/ptitjo/furmark_pre.png

Here's right after repasting:

http://i255.photobucket.com/albums/hh155/ptitjo/furmark_post.png

I'll check tomorrow at work to see if as some said MX-2 has a short curing time. Anyways it was my first paste so i didn't expect it to be perfect. If i have to repaste in the future, i'll do it with ICD7 to see if the results differ.

Thanks to Chastity for all the info given, vBios etc. and also to ValkerieFire for his newb's guide to repasting.

EDIT: everything was easy until the keyboard, that doublesided tape was probably made by the devil.

EDIT2: I know those temps are about average but still i'm happy it's no longer getting too hot and i got the same results at work.

 

Those temps look about average!

 

today i tested my laptop in AC room and set the AC temp. 22C and played some game(GTA4 and crysis 2) GPU temp. never crossed 76C

 

Is that 76oC as the highest temp GPU-z/Hwinfo32? I hit that for my DISP and DIODE during gaming but reach 84oC on MEM(iO)

Good temps either way though I love the fact I can game and my fan does not kick above 3600RPM

 

i also reach 84C when i am playing game on Non-AC room which i do 90% time and mostly thermal diode temp. always remain 2C above ,rest sensor show same temp .

 

Looking to do a repaste with IC7 once I fit my 920XM.

Could someone please confirm the width of the GPU RAM thermal pads are they 3 or 5mm?

Thanks

 

They looked like 3mm ones when i repasted yesterday. Too bad you didn't ask a day earlier . Anyways i'm pretty sure someone here can confirm if they are 3mm pads.

 

Yeah I thought they looked like 3's when I opened her up but they do not seem to fit perfectly im wondering if 5's will squeeze in but need to be sure that the heatsink will touch the diode before making a choice like that

 

I get about 90 degrees after about a hour playing rift on ultra setting is that bad??

 

Use HWiNFO32 and check your memIO temps. If that's the mem temp (TSS1 in GPU clock tool and GPU-Z). If that's the memIO, the you're good to go. If you get memIO over 100C, then time to repaste of have it repasted.

 

Are you checking your temps with HWINFO32 or GPU-z?

If not then it could be because if thats the DISP or DIODE then your MEM(IO) temp could be reaching into the 100's its best to check all of the temps of the GPU using one of the above programs and feel free to post your results so that you can be advised further.

Firstly I recommend you trying to blow out your fan vents to dislodge any dust that could be blocking the heatsink. Check the temps first though.

 

GPU-z is what I used it show 58degrees idle and 90 when I play for a hour on ultra settings

 

It should give you 3 temps the 2nd is the most important because that is normally the highest in most instances as its the MEM(IO) are you getting 90 on that sensor after an hour of rift?

If so then you have nothing to worry about thats a perfectly normal running and idle temps for stock paste. Furmark may push you towards the 100 mark but anything upto the 100's is fine only when your nearing 105's do you really need to think about a repaste.
