Once I used nivea and it worked 😐

I don't really understand why people pay $6+ for AS5 when $2-3 stuff is at most 1-2c worse. I think that the buying of AS5 is more about the brand rather than it's effectiveness

I just have a tube of dielectric grease. It's great for lubricating bearings and gears and also works as a great low temperature thermal paste.

honestly anyone paying for AS5 is still living in 2005, I happily pay 20 bucks for a big tube of Antec Nano Diamond 7, who needs silver when you can have shattered diamonds

I use the soviet thermal paste from the 70s for all my computers, old and new:

First thermal compound I tried was Implastec/Votorantim on a PowerMac G4, but it was too basic and didn't conduct much heat. The best one I ever used was OCZ Freeze, followed by AS5 and AK455.

Nano-Diamond is my fail-over paste when Arctic Silver 5 is not available. Both pastes are seemingly equal but the reason I default to Arctic Silver 5 is simply that if you purchase a large quantity, it works out only marginally more expensive (a few pennies) than the regular white/pink/yellow paste that comes with cheap heatsinks. The Antec paste is prohibitively costly for no real gain.

The more expensive pastes actually do offer a noticeable advantage provided the surfaces are prepared properly and the cooling system is adequate for the device which it is supposed to cool; the temperature falls off much faster with good paste, which is about all it will do. The overall temp won't change much because you are using the same surface area to cool the device, so you could use almost anything as a thermal interface material (Let's say, saliva, or butter, both of which I have used when briefly testing something) and have it work to achieve about the same temperature (within a few degrees) but remove the load on the device and it will take longer to cool off due to said material being less effective at transferring the heat (the former of the two examples also begins to smell faintly of cheddar cheese if the temp gets too high for some reason). The effect is even more noticeable if you grossly over-engineer the cooling system as I do, such as using Socket A coolers for Socket 7 processors or, as a more recent example, using a 120x120x60 copper radiator to cool a single Pentium D then adding a second one to cool a GTX460. Whilst pushing fluid through the loop at a rate of around 750 Liters per hour.

I actually read a review where such exotic thermal interfaces as bubble gum, tooth paste and condoms were included among AS5 and mates.

And no, the top temperatures are not equal. If you look at Fourier's law, given that dQ/dt is constant (say, 200W), lowering conductivity (λ) means raising temperature (dT).

Where did I say it didn't? I seem to remember explicitly stating it did but the effects would not be particularly drastic with the materials the average person is likely to have on hand. Stop being so fucking contrary, I'm sick of this shit already today.

Oi take it easy, RacoonRider was just peacefully making a point. He even went to the trouble of including a diagram which I personally don't understand, but which I'm sure is pertinent and enlightening to the properly educated.

There are some lists of thermal compounds around internet that are infamous for listing butter, chocolate, oil, mayonnaise and others. There was even an extended list that listed some bodily fluids 🤣....

Now, I could tell you a few stories about early adopters of liquid cooling involving those... But that's for another time.

Interesting how butter is only 2-4C worse than some of the lesser pastes there, makes me think I ought to use that more often... Or mayonnaise! 😁

Hightreason, you are really an asset to the forum. Where ever you post, there is almost certainly action. 🤣 (mostly without a cause, to tell the truth).

And you did say there (at least it might be read like what racoonrider get):

And I really suggest not being sick at the first sign of somebody being contrary to you (it's unhealthy, to say the least).

This is what I was expecting: a temp differential between the highest and the lowest quality pastes is only 6 degrees. I can easily live with that (actually I do). And don't even make me start about those overly exaggerated liquid cooling systems... 😈

The operative word being MUCH, you back this up (along with the chart) in your next post...

I was going to write something more in-depth, but I'm done with this.

As a last note, liquid cooling for the sake of it is pointless, but there are applications which require it. I for one cannot run on air cooling due to the lower half of the case being fairly cramped and the huge stack of hard drives, RAM and the heat given off by the expansion boards. By the time air gets to the CPU, FETs and PSU it is already very hot, a hotspot also then forms near the RAM and 60°C is NOT an acceptable full load temperature in my mind. As a result, the liquid cooling was installed to move the heat from the CPU and GPU away to two large radiators at the upper-rear of the case where the only thing they can heat is the optical drives and the Audigy 2 bay. If the case were designed differently I would never have forked out for it, but there is a valid reason for it's existence and installation under certain circumstances.

The water blocks have always had, and will probably always have, even after I move the old board back in soon, Arctic Silver 5. The fluid by this time is an unknown composition, it was Feser 1 a few years ago but now it is a slimy green/yellow substance which smells rather toxic as it slowly drips onto the Audigy bay below the reservoir and seeps out of a spigot on the GPU when the system gets warm. I will be applying the duct tape to fix that when I sort the board out... Anyone want reports on the thermal properties of that? No? Ok, then.

Actually, why isn't double-sided tape on that chart? I've seen that stuff used everywhere and I've always thought it to be rather poor.

well to be totally honest with you, with AS5 paste that I did test on my FX6300 my temp under load reached 68C with my nano diamond my temp under load reached 65C that is a difference, and that is overclocked.

Cool! Nivea creme was not that crazy after all. But I spot an error on the chart, it shows "no thermal compound" as being better than "chocolate", but everybody knows there is nothing better than chocolate.
Also, all those brand pastes worst than mayo, 🤣

Copper paste works good 🤣

Actually this could be a very good idea. Cooper is good right? Where do I get this, is it cheaper than specific PC products?

I remeber when i replaced the titan paste on my overclocked 2500+ Barton,with as5,back in 2004,it dropped the cpu temp with about 5-6 degrees,so it was worth the money.
I agree,that it's not the best compound u can find this days and it's not worth using it on low frequency old cpu's,but it's a good compound,i still use it on my main pc.

I use MX-4 for the most part. I used Coollaboratory Liquid Ultra a few times. Nice stuff so long as you don't mind lapping your cpu/heatsink everytime you remove the heatsink. 😲

You also want a thermal paste that is easy to remove/clean...
I never tested/trusted cheap thermal paste because of some socket A/370 cpu coolers from computers/MB's I bought years ago...
That was a complete pain in the ass to remove their cpu cooler and to clean the cpu (even after running the pc to warm the HS a tiny piece of an AMD Duron cpu die stayed on the HS while separating the two 🤣 ).
The culprit was the thermal paste (yellow or orange ones) that has completely dried and became hard as f*** and that won't even come easily or at all with White spirit or acetone alone 😵
