The result is promising for holding the GPU core go higher as compared to stock thermal paste...

too bad there is only minor decrement of temperature during idle....

seems like Gigabyte cooler did nice job in keeping the stuffs cool ....

Nice results there but having 8ºC drop in GPU temp by just changing thermal paste sounds ridiculous. Don't get me wrong but you could be mislead by your setup.

Firstly, I see that you are using dual 7300GT in SLI mode. So, there should be two GPU core temperatures displayed in NVIDIA Control Panel. Since you are only showing a single GPU temperature, I'm not sure if its GPU1 or GPU2.

Secondly, I see that you have a Delta fan blowing towards the GPUs. Not sure if the fan was there during the initial test w/o the STG1. If the Delta fan was there from the begining, it should be in the exact same position. If the fan moved a little, the fan could be blowing towards another direction from where it was originally seated.

Thirdly, you didn't provide any ambient/room temperatures for your setup. Room temp could have dropped after the initial testing w/o the STG1. You also didn't state the stres (100% load) or idle duration for both CPU/GPU. You have to make sure the testing period is consistent.

Lastly, I noticed that your GPU temp (with STG1) did not increase when overclocking. At 500MHz, its loaded at 49C, and maintained 49C even when overclocked to 620MHz. I suspect the GPU could have reverted back to stock clock instead of staying overclocked. This is why you should have RivaTuner's Hardware Monitoring tool running throughout the test.

I hope you don't get me wrong here but we appreciate your effort in doing these tests. Its just these few little things that you need to consider before doing such tests. On the other hand, your CPU results seems to be pretty consistent.
And btw, the original thermal paste on the 7300GT is not by NVIDIA... its applied by Galaxy. NVIDIA doesn't sell 7300GT with Zalman coolers.

Really pro men.... too bad lah not everyone here has deep experience and sufficient tool to test it out ...

i would even prefer if the test is run within the case to simulate real world condition .... majority wont be having Delta fan blowing here and there....

anyhow there thermalpaste should work fine maybe slightly on or off compared to AS5...

Well, i might be going to LYP tomorrow and get myself the Zalman there.Any place in LYP also selling AS5?Then maybe i can compare them with my stock Galaxy cooler and see how much difference the Zalman can make on stock..

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.

Kuang. kuang kuang.... Hehehee... Buat test tu pun lepas beli... x der preparation pun.. Heheheee!!
Oh, my bad.... many mistake... Sory2..

tapi, result tu aih yg dpt..

will check the temperature again after 1 week...

Thanks for correcting me

Wait for a little more days..
Who knows either that thermal paste is just like AS5, need time to sink in before it perform to the max...

Right?

I'm having similar result too, my proc temp increase by 4-5c. Mebbe we need to wait until the paste cure in. B4 this, I used AS5 thermal paste. My method of applying is a bit differ from yours.

1. I used alcohol to clean my proc & heat sink
2. I applied the paste on the proc & the heat sink surface

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.

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.

Usually i only applied one side and use the plastic card to spread very even not too thin until seeing the die.... not too thick either until there is excessive paste squish out when the proc and heatsink contacted.

I applied on one side previously with AS5. But with ZM-STG1, they say I must applied to both side.

from Zalman's website...

Application Instructions

1. Clear off particles or residue from the contact surfaces of the heat source and heatsink.
2. Shake well then apply on the contact surfaces of the heat source and heatsink.
3. Install the heatsink.

ic ic .. maybe but there is no harm to try on one side but evenly spread is the key of succes...

I never applied any thermal paste on both part...
Only applied the thermal paste on the processor's IHS...

Don't know about zalman thermal paste though, if i were to use the STG-1, do i need to apply on both surfaces?

i applied both side too... it is written at the bottle itself and on the official website. hopefully it will bring down my temp after seven days else i think i just threw my RM32 into the drain. haha..

Hey, if it fails you, dont threw it away, give it to me liao...
I'm in need of thermal paste now, finished my AS5 aedi...

hahha same here ... but i would still perfer AS5 as it is much more stable when comes to applying it .... just apply and wait for a day or two to fully sit down ...

sometimes life should be simpler....

Zalman ZM-STG1 is the one that comes with Zalman CNPS9700 right?

yeah ZM-STG-1 comes together with the cnps9700led packaging here

ermm.....lately got some un-natural readings on these zalman's STG-1 based on my fellow frens here...

some of my customers here are using it with some significant temp drop after 1st application...but some seems to have higher temp reading that stocks thermal paste..

i try to liase with zalman korea as i've some contact with them before...see wheather they have any latest issues regarding this newly zalman stg-1 here

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.

probably i can sell to you cheap cheap since i only used once
