i would like to know what is the best thermal grease in the market? i would like to know there differences.

thank you so much!

Have a look at ArcticSilver Instructions
Here's some of the compounds there
Also don't forget that you still need a good Heatsink

Looks like to me the differences are CPU hardware related, not so much which is the best compound

thanks so much.....
although i am using only the silver type grease, the ordinary one...

I also just went out for some Arctic Sliver 5 Thermal grease today, decided it was time to get rid of the stuff that came with the heat sink. I was a bit disappointed that it cost 10$ for such a small amount of the stuff, and another 4$ for 500ml of 99% isoprophyl alcohol, but you also only need a little less than the size of a BB to apply so It will last me a long time as well as a still have like 480ml left of the isoprophyl alcohol.

I have to say that after cleaning my computer and applying the grease to my CPU the temperature has gone down from 34 Celsius to 26 Celsius and It also takes some time for the compound to sink in which will also make the processor a bit cooler. My room temperature is about 22 Celsius and my CPU is slowly doing down in temp.

I'm happy ;D

BTW if you get isoprophyl alcohol to clean off the thermal grease don't get one with anything less than <70% really I wouldn't even go under 99% or else you pose more of a risk of damaging stuff.

That silver stuff is supposed to be good, like everyone above just said.

i am from the philippines and my pc is not in an air-conditioned room. my processor is an intel pentium d (dual-core) 2.8 ghz. idle temp is around 48 degrees while load temp is around 53 degrees and my motherboard temp is around 39 degrees. i have installed the necessary exhaust fans and i always clean my pc every month. so is my cpu temp ok or not? im using the silver type thermal grease, the cheap one actually.

thanks!

i just applied the silicon thermal grease that my Zalman Fan Came with.... but im having issues... my temps are in the 50's C. Im gonna switch it out for artic silver 5

The thermal compound does have an effect on the temperature, but to an extent. Temperature can depend on your processor model, current cooling solution, ventilation, cleanliness, your climate conditions, the amount of operation time and load on the CPU.

Make sure that your case has adequate ventilation, air must be moving threw your heat sink in order to cool it so even if your case may be open if their are jumbles of wires or dust near then it will effect the ventilation just as badly as if your case were to be closed, be sure to clean your case often and keep wires from hanging all over the place. If you have over clocked your CPU or it runs at a high clock speed that will make it run warmer. If the CPU uses a larger architecture and consumes more power it is more likely to be warmer.

Thermal paste can have drastic effect on the heat but If you already have it properly installed between your CPU and heat sink then switching the thermal paste may have a slight effect but It might not be the answer. Buying a new cooling solution for those with higher temperatures would do you more good.

Good operating temperatures would be anywhere from <49 Celsius but if your going over 40 you might want to find something to cool it down. 50-65 Is getting a bit warm and might start to pose a risk. Over 66 you should probably start thinking about a new cooling solution, thermal paste probably won't do you to much.

Make sure you can trust your temperature monitor as well, some can give bogus temperatures.

yea i was having problems with the heatsink... the clips that came on my zalman fan were not connecting rite

i fixed em now im getting 29C - 36C

Nice, that seem pretty good. Much better than before =3

much better Thanks XD.... im still gonna put artic silver tho lol

so these means that even dual-core cpu can get around below 50 or much better below 40???

Yeah, mines a AMD athlon 64 X2 4800+ and its at 26c-34c.

Not to say it doesn't get warm, when playing COD4, Crysis or COH she does get a bit warm, 48c is the most I've seen it get to though.

yea i got a E6750 and with arctic silver 5 and an asus block cooler i was at 35 idle 46 Load... but my room is hot...

i switched it out for a ZALMAN 9500 but i had no arctic silver left so i used the silicon paste that came with it.... pain in the *** to apply... but im happy with 30 - 39 temps.

i want to redo my thermal paste with Arctic Silver just beacuse its less messy than the silicon crap... but any ways make sure that your heatsink is sitting correctly on your CPU. your CPU radiates heat from the center usally so that would be the most wise place to apply thermal paste...

Yeah, remember like the instructions say don't put to much of that thermal grease on.
About the size of a BB in the centre. All your trying to do is make the processor have as much contact as possible with the heat sink so putting to much grease will only make you worse off. What ever you do DON'T do it like this guy.

You have to realise different makes have different operating temps. The Pentium Ds are notorious for running pretty hot (and thus, higher normal operating temps). Same goes with some Pentium 4s (Prescotts anyone?)

You nailed it there. On board temperature monitoring isn't accurate at all. There was a test somewhere (if anyone would be bothered checking really old threads) where the temperature can differ more than 10C from the actual temperature (measured with a seperate, calibrated, probe). And the temperature changes aren't accurate neither (can't remember what thats called).

Anyway, just wanted to point that out.

About that link:

Thats actually the wrong place to put the thermal grease, so don't even think of a BB sized thing anywhere near there.

Besides, the guy could be laying di-electric grease (however you spell that). You'd need that kinda amount if you were doing that. Wrong color for that I think.

Less is more when it comes to thermal grease. But too little isn't good neither, and the only way to know if you've got the right amount is to apply what you think is the right amount, fully complete the installation, take it off, and check how much it has spread from where you originally put it. repeat until you've found out how much you really need.

It'll be somewhere between half a grain of rice, and a BB.

Although I personally did that, I think that its too much of a hassle for anyone other than enthusiasts (the gains aren't that great neither).

This one?-->http://www.techspot.com/vb/showthread.php?t=98948

Not old enough.

I'm talking sometime mid 2007 I think.

Thats just comparing different monitoring programs, but it'll do in supporting my point.

Aha sorry I probably should have mentioned that about the picture before =p

so bottom line pentium d dual processor operates on higher temperature like around 50, i guess?
