Official ICD7 Thread

Let's take this and generalize somewhat:

A CPU will generate a certain amount of heat under a specific load.

A specific HSF can dissipate a certain amount of heat.

While the various pastes, for the most part, may be very close in specs to the amount of heat they can transfer from the CPU to the HSF (although some may spec out better), the quality of the installation (complete coverage, no bubbles, etc.) will go a long way toward the overall efficiency of the heat dissipation of a particular installation.

Someone with a near perfect setup with any good paste may be getting very close to the optimum.

The fact that relative "noobs" can remove the "professionally installed" paste and replace it with ICD7 and then report a better (cooler) set of temps would seem to show that overall, the ICD7 will give close to the best results most of the time due to it's ease of installation.

Hello_Moto may have been one of the very fortunate ones who actually had a very well done system, which seems to be supported by the fact that the ICD7 didn't change anything very much.

Except - he should now feel comfortable that he has a system being cooled as well as possible without making any sort of major alterations.

At least, that's my take.

What you, and a few others, evidently, are missing is the part about 8+ hrs of stress testing....seriously......8+ hrs! Lets all run our notebooks at 100% load for 8+ hous and I'm sure all of us would have some pretty high temperatures.

Again....a 45W processor under a HSF built for a 25W processor, then stressed to 100% for an insanely long duration....the temperatures are not surprising......the thermal compound isnt even close to being the issue here.

I always stress-test for long periods of time, overnight if possible. I've presumed that to be the norm for OC stability/TIM application; obviously i'm mistaken as Capper doesnt seem to share my enthusiasm for 8hours + of notebook stress testing.

how long do you normally Orthos/OCCT/Core Damage, out of sheer curiosity?

MrButterBiscuits · 07-09-2009, 06:40 PM

You really want to stress test... use OCCT lol

Hello_Moto · 07-09-2009, 06:42 PM

I do...OCCT 3.1. It generates nice graphs! Also use Orthos and more recently, Core Damage.

That is separate from what I was saying.

However, on this issue I agree with you.

Cant be that bad though, unless the 78xx series really downgraded the cooling system.

I'm running an x9000 (44 watt just like x9100) in my 6860 and i idle at about 32-34 degrees once my thermal goop settled

Acer used a very basic cooler, pretty generic. the 45W processor vs 25W cooler is not an opinion, its fact. maybe you are idling at -15C, but take into account things like ambient temperature, supporting surface (desk, lap, car seat, etc).......there are quite a few variables to take into consideration. As Moto's CPU was an ES, it might be an early revision.....it might have come of a crappy part of the platter, who knows.

If people want to run 8+ hrs of OCCT, thats perfectly fine......but this is not a desktop, its a mobile platform.....even if it is a desktop replacement.... and aside from benchmarking just to benchmark, I think its a little bit of overkill.

I realize that most of us here like to tinker, and thats great.....but you also have to be realistic in your expectations of not just the thermal compound, but also in the notebook as well.

I ViciousXUSMC hereby support this statement.

Im going to make alot of people mad with this statement but here it is. Stress testing like this is dumb! you know in the army we just got these fairly new trucks called MRAP's that are better armed against IED's. They stress tested those with explosives, BECAUSE that is what it will be used for. Stress testing you CPU for hours on end with a program that puts it under a huge load is nowhere near the same. Are you ever going to play a game that is going to max out you CPU like these programs for eight hours? Probably not so this to me is just a waste of time. Now let the hate flow
