7811fx ICD7 Application

I have always had temperature problems with the GPU on my 7811FX. I bought the NZXT Cryo LX laptop cooler, and that dropped my temperatures a bit, but they are still regularly 100C+ while gaming. I came across the ICD7 thread and am hoping this might be the cure to my problems. That, along with the 78xx series breakdown thread, I think I may try to tackle this.

That being said, I have a few questions for the NBR community.

1) When applying ICD7 to the GPU, am I applying it to the heatsink, or on the thermal pad on the GPU?
2) I've read several places that I am to remove the thermal pads from the components that I am applying ICD7 to, is this correct? If so, what is the best way to go about removing them.
3) I applied AS5 to my CPU previously, what is the best way to clean that off before applying ICD7.
4) Any other words of wisdom?

Thank you for any assistance.

 

Hi Kluckock,

1 - On the GPU die, discard the thermal pads

2 - It's correct

3 - Thermal paste cleaner

4 - Take a look at these part1 and part 2 videos. The same steps you should apply to GPU as well.

 

Other words of wisdom, since the density of the ICD7 paste is very high you should boil some water really HOT and then put the closed ICD7 tube on the water for a few minutes, if you do this you will find that its easier to apply the thermal paste.

 

I really appreciate the replies so far. I ordered my ICD7 and cleaner, should be getting it in a few days. Any info on the best way to remove thermal pads? Thanks.

 

Pull them off with your fingers, then stick them on the faces of sleeping people.

 

Lol, or try putting them in place of Trident chewing gum and ask if people would like cooling peppermint...

 

Question:

Wouldn't the same thermal paste cleaner also clean any residue left by the thermal pads?

 

I followed the 78xx series breakdown, took my laptop completely apart, applied ICD7. I just completed running 3D Mark and my max GPU temp was 64 !! That's 40 degrees better than what I was previously getting. I'm so happy.

 

I can’t believe it the change in temperature on my CPU when I was creating an image with Acronis trueimage RM clock was popping up with an WARNING Your CPU core over heating to 100 C Now after applying ICD7 my temperature
It’s 69-70 C and idling it was 52C now 45-46 this staff it is GREAT!

 

I suspect it isn't simply the ICD7.

It really sounds like your original paste was not applied properly.

May be the same problem regarding kluckock's GPU situation.

For both of you - it's great to hear that your problem is resolved.

 

Agreed, no thermal paste will give a 40 Degree drop over another one.

I'm pretty impressed with the constant 3-6 degree drops though. I'm almost tempted to try to hunt down some ICD7 or ICD24 (have no idea the differences in the two i've just seen the numbers floating around) and give it a try.

I think it will be hard for it to beat my AS Ceremique application. Now that its settled in well i'm idling at 37/39 degrees on my x9000 @3.0gHz and maxing out at about 62/64. Still i guess i could try it out eventually, but i doubt i will see a huge drop in temps (plus as i cant OC anymore i'm pretty much stuck where i'm at temp and preformance wise)

 

Kamin,

The difference between the two is that the ICD7 tube weight is 7.6 carat and the ICD24 weight is 24 carat. There's no other difference.

I guess, with the ICD7 or ICD24 you should expect to get 2-5C lower temps in comparison with the AS Ceramique. You can try to put this compound on the CPU only and see what you get.

Cheers...

 

No idea what a carat is, but i'm assuming its just a larger tube.

If thats the case i very seriously doubt i would ever use more than the small tube even if i applied it to my CPU/GPU/vRAM in one outing... unless 7.6 carats is REALLY tiny

 

aren't "carats" a measurement of mass in the context of precious metals/gems?!

given that ICD7 is 92% diamond particles, i guess that equates to a tube size approx. 3 time larger to the 7.6 carat tube.

 

Kamin,

As Hello Moto mentioned the carat is the measurement of mass.

The one carat is 200mg. So in 7.6 carat tube you get about 1.5 grams of paste. I think that will be enough to apply on these three components. You will have to use more of this paste on the GPU than on the CPU as you know. But, if you can get the larger tube so get it, to be on the safe side.

Frankly, I put the ICD24 on the GPU, CPU and chipset in my M6850FX and still have this compound to use on my second machine.

 

I learned something new today... i did not know thats what carat always refered to with diamonds... neat

 

Right now with ICD7 applied (on both the CPU, NB, GPU and GPU mem chips) on a 7811, I'm idling at:

TZS0=45
TZS1=45
core0=38
core1=40
GPU=38C

Under load (playing L4D) I'm getting 74C max on the GPU (sounds right?)

Is this what you guys are getting?

 

You used a small tube of ICD7 for all of that?

The ICD7 tubes seem like barely enough to cover the CPU and NB
