[Cooling] Thermal Compound Review

As I was almost out of AS2 I was faced with buying something else but if you havent noticed, thermal compound is growing in price. I looked at all the reviews i could find but didnt see much of a difference between them so i decided to buy a few tubes and test them myself.

The test was run with my 2400+ mounted on the 8K3A+. Since it reads temps directly from the cpu diode I figured it would be the best way to test..... its also the most accurate board I've ever used for reporting temps. I used my AX-7 with the Delta 68cfm 80mm fan. Each test was started with the cleaning of the cpu. I used nail polish remover first then alcohol to make sure nothing was left on the core. The same was done for the HSF.

The compounds were (in the oder I tested them)

-Artic Silver 2
-Evercool 350 Silicone
-Artic Silver 3
-Artic Alumina
-Nanotherm BlueII
-Nanotherm XTC

Just some notes about the compounds. AS2, AS3 and XTC are all silver based so they would be slightly conductive. Artic Alumina and BlueII are ceramic based and nonconductive. The Evercool is the silicone "white stuff" and non conductive.

I started the system and let the cpu sit idle for 5 minutes before recording a temp. I then started Toast and ran it for 5 minutes before recording a temp. I ran each one twice (cleaning between each) except for the BlueII. The results confused me so i checked the Nanotherm site to make sure i was applying it correctly. I was but reapplied and got the same results. BlueII was tested 3 times.

The results were:

-Compound - Idle - Load

-Artic Silver 2 - 36C - 44C
-Evercool 350 Silicone - 38C - 48C
-Artic Silver 3 - 36C - 44C
-Artic Alumina - 36C - 44C
-Nanotherm BlueII - 39C - 49C
-Nanotherm XTC - 35C - 43C

I wouldnt say any of them were clear "winners" since a 1C drop isnt anything to get excited about. I was surprised with the BlueII since the reviews I read said it was great. I knew going into this that the white silicone Evercool wouldnt be the greatest.

I would have to say your safe using any of the 4 best temps but I'll be using Artic Alumina from now on. It isnt conductive and its about half as much as AS2, AS3 or XTC which are all about $8 a tube (alumina was $4)

Excellent job Maranello.

Great big

Note to self : Must buy some Artic Alumina

For how long did you leave them on?
Most of these types of compounds have 2 to 4 day cure time to reach optimum thermal efficiency.

Good research, my man!!!! Appreciate the time you took to do those tests....

On a side note, how good are the small syringes of goop that Thermalright packages with their SK7's? Going to be sending a care package to Canada, and he needs some goop.

Yeah, it's white. It's not a really small syringe like the ones Evercool packs with their hsf's, it's quite a bit bigger, looks like a generic syringe, no markings like the small Evercool syringes has.

Oh, hsf finally got here today for the p4.... wh00t!

i was kinda curious of the same thing....if this was tested all in 1 or 2 days, those temps won't be accurate....a test like this should take a couple of weeks minimum to be able to get the correct results....

taken from Arctic Silver's site: »www.arcticsilver.com/arctic_silv···ions.htm
quote:
Important Reminder:

Due to the unique shape and sizes of the silver particles in Arctic Silver 3, it will take a minimum of 72 hours, and as many as 200 hours to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink.) The CPU's temperature will drop as much as 2C to 5C over this "break-in" period.

I dont buy into the "your going to need days and hours" hype. IMO and from what ive seen over the years, what you get after you apply is what you will have long term. I stole the AX7 off the 1600+ machine ... the board i used usually runs my swiftech water block. the 1600+ is running with AS3 now and the 2400+ XTC..... its been about 14 hours and there is still no difference in temps then what there was when i first turned the systems on. if i ever see a temp drop its usually +/- 2C which is nothing to dance about and most likely its a change in ambient temp causing the temp flux.

very good work Maranello
I definitely agree about the set-in period for AS...
I've had my AS3 on for a few months and haven't had a
temp drop from when I first applied....

(well, other than when I open a window or something )

It needs more then 5 minutes to settle in dude

I have to agree regarding AS alumina. Can't really beat it, performs well, non-conductive and really easy to clean up. I've been very happy with it so far. Nicely done Maranello.

"optimum thermal efficiency"

does that sound like PR to anyone else but me?

I also agree with Maranello and libertate. Never seen more than a 1 degree change from the initial temp and the temp weeks, even months later. This has been true for a tube of Alpha compound, ASII, ASIII, Shin-Etsu and Type 44.

its been almost 24 hours now and the as3 system and xtc system are still within 1C of their load/idle temp on first boot after application. i think it is a pr thing.

kat suggest that the "settle-in period" or "cure time" is marketing-hype
...or possibly "ghost in machine"...

...change processors, mainboards, hsf's frequently...
most due to premature demise of mainboard, unfortunately...

never see improvement in temp over time with asII or asIII
....and so return to type 44...

I'd just like to add my 4 dollar CoolerMaster HSF, unlapped, using the included thermal compound, keeps my XP 1700 @ 10x191 (1.75v/2.7v) running cool at 38c full load. At stock it runs 27c full load. Wonder what I could do with an SLK-900.

ok..kewl....i don't change out my HSF/CPU near as often as that requires $$$ ...so i am no expert on the subject...just have to go off what i see....with this being the case, it is all good then...hehehe

I'm sorry, I was not doubting you or your testing methodology.
I had just recalled Ugly's post back in November on this very subject, with info garnered from an article on the insideprojects.com web site.
They had found that some of the compounds had in fact improved with age during there test.
I know nothing of this web sites reliability, but with this test they seemed to be doing a studious job.
