that really looks like liquid paper in a bottle. tamiya cement seems to use similar bottle. heehee.

i was wondering, do you people actually reapplies the thermal paste after a while? i havent actually taken out my hsf for reapplication since it was stuck there.. 2 yrs possibly, definitely more than a year, and i cant really see temps increase. im also wondering about how long does it takes for tim to deteriorate.

currently running at 245fsb 2.9, double prime would currently still be at most 61, mostly 60, or 59 if ambient temp is cool, or 58 during rain + opened windows. and those are the very same readings i got after er.. probably 3 or 4 days after applying the thermal paste. initially it was higher, i primed immediately after applying, then cool off my pc for about 3 hrs, then primed again, for maybe half day, then cooled off.. then normal usage.

using as5.

Now that's weird...
After two years and there's no increase in temps? blink.gif

Two years you didn't take out the heatsink?
There must be a lot of dust accumulated there... sweat.gif

probably i can sell to you cheap cheap since i only used once smile.gif

No problem one, can always discuss it through pm right... brows.gif

i didnt take it out. i cleaned it regularly though.. use brush, n blower. the heatsink is dust free, but the issue here is the tim.

overclocker paradise is selling AS5

edited (Off Topic): is there any special method to apply zalman ZM-STG1? i just got that from moderno and after i applied it, my processor temp is higher (4-5c) than previously. before this, i used stock grease from intel. is it i need wait it to sink in before i can see the difference?

1. i used artic cleaner to clean my processor.
2. i put the grease on all the surface of the processor.

any problem with my application? i already checked the processor heatsink, it is properly intact.
*
it is just my opinion.. correct me if i'm wrong.. i think thermal paste such as AS5 and zalman STG1 need a good heatsink to be compiled together..

it is because when using high performance TIM the heat transferred is more efficient than normal paste..

so for that matter we need a good heatsink to dissipate the heat out quickly and efficiently.. thumbup.gif

I think stock cooler cant do that.. whistling.gif

Owh, my bad then...
But still, after two years, the TIM should deteriorate? No? smile.gif

Weird thing is, you didn't experience any temperature increase even after using it for two years... sweat.gif

Actually you no need to be pro lah.
I'm sure even normal user will feel weird when they see the GPU temp at 500MHz = 49C and overclocked to 620MHz also = 49C. Besides, having 8C drop by just changing thermal paste is a miracle, unless the original thermal paste was insufficient.

bulibulizaimon, can you please check again to see if the GPU temp is still maintained at 49C even when overclocked 620MHz? This time, have RivaTuner Hardware Monitoring tool runing okay.  smile.gif 

I'm seeing a few users here experiencing higher temperature after applying STG1 (before cure in), which seems to be similar to my experience. For some reasons, you happen to be the only one to obtain better results after applying STG1.

Ok, will take a screenshot of RivaTuner hardware monitoring with OC n unOC of the VGA..

BTW, im having the same problem, increase of 2-3'C at CPU from the previous thermal grease.. Im feeling weird and pull back my heatsink, maybe i dont give enought i think, so i apply another layer on it.. and thats the result i got.. Not much different from the previous thermal grease.. Have to wait couple more day to get the optimal result..

Recently due to my laptop cpu temperature rising till 82 degrees i decided to diasemble the whole system. I found out that the heatsink is blocked. Gaps between the copper fins were totally blocked with dirt. I cleaned it and did some lapping on both my CPU heat spreader and the heat sink base. However i couldn't acquire any thermal grease to apply. I asembled back the whole notebook and it's CPU is now lower by 30 degrees at maximum fan speed. Will there be any problem if i keep running it without any thermal grease? My lapping wasn't mirror shine either.

Anywhere selling thermal grease at Subang Jaya area? Preferably Artic Silver 5.

Thermal grease and thermal paste both are the same things, just different name.

with that temp, it is better for you to put some new grease.. 100% your processor got contact problem or thermal grease really 'gone' already. you can get it from Moderno shop at SS19 behind Hong Leong Bank.

There are many members selling thermal grease under Garage Sales. You can go with Artic Silver, that's the best thermal paste ever made and it gives significant reduction in operating temperature of your CPU. It's good stuff. thumbup.gif

why on earth call the thermal paster as grease ... grease is use to reduce the vibration and friction of two object contacted on one another,,, like gear, bearing or joint.

thermal paste is use to fill up the gap between two contacted objects to improve heat transfer.....

actually i am joking about selling off my zalman thermal paste. RM30+ item also need to sell meh.. haha... if u want to try, i can borrow you for single application. let's you try it smile.gif

Because thermal grease is a thermal paste biggrin.gif http://en.wikipedia.org/wiki/Thermal_grease

Anyway i moderno doesn't have stock for artic silver 5. Now trying to ask whether he got stock for the zalman 1 or not

Where is Ho Leong bank in SS19? I only remembered the bank in SS15.

You can choose either to use thermal paste / grease on the notebook or not by you're choice...

Normally notebook manufacturers didn't bother to put any Thermal paste / grease between the processor and the heatsink...

I've repaired so many notebooks, and open a lot of their casings [i only open the notebook casings that the warranty is over already laa laugh.gif] and none of them uses thermal paste / grease... smile.gif

Every notebooks that i've opened, i'll put some thermal paste on top of the processor die, coz this will help more in transferring the heat to the heatsink...

So my suggestion is, put a thermal paste, it's better that way... smile.gif

Ahh, another thing, if u look on the heatsink, did you find somekind of metal zink sheet?

If you do, take it out, then clean the heatsink with some alcohol, then apply the thermal paste to the processor die itself...

The themal paste will work better if you take out the metal zink sheet... wink.gif

Ohh, and by the way, you don't have to use AS5 for notebooks processor as they are cool enought to be use with those normal white thermal paste... thumbup.gif
