Hello, I received a CPU with the fan and thermal grease. There were no instuctions, so I put the grease on those 4 black circular things on the CPU and nothing else. Was that all I need to apply? Thanks

NO, you did it wrong. the grease always goes in the center, depending on the processor, it should have a "bulge" in the center. you should know this already, but use only 1/2 of a grain of rice, and it will be enough

NO, NO, NO!!! Those are the support pads & should not have been touched! The thermal compound should be applied as a paper thin layer on the CPU core ONLY! The core is the small raised square right in the middle of everything. Clean that stuff off immediately (& carefully) & do it right or you'll fry your CPU...if you haven't already!

Wait, are you guys serious? Please don't lie to me, this is very serious and it could cost me a lot of money if I do this wrong. I am not supposed to put it on those pads alone? Or not at all? it may be a stupid question to you, but I am new, so I am learning the same way you did.

Ok, I did a search to make sure you weren't pulling my chain :) I didn't see anything that said you couldn't put the grease on teh support pads though, after all, they are just little rubber pads right?

the rubber pads doesn't matter that much, what is important is to have the thermal compound on the CHIP, modern CPUs fry in less than 10seconds if cooling is not provided

Ok, I wiped the grease off the black pads and applied a tiny bit of it to the center of the CPU. It is a 900mhz Duron anyway, so it isn't like it is pushing 2.53ghz :) I thought that grease helped cooling, but your CPU wouldn't fry in 2 seconds like everyone says? I thought I heard some people say that they dont even use any grease, is that true? Also, will the grease turn to liquid once it reaches it's normal operating temperature? Thanks

What kind of logic is that? I bet if you do another search, you won't find anything that says you can't put the grease on your forehead either, but that doesn't mean you should do it! LOL!
Seriously though, the grease should be applied to the CPU core ONLY! Any compound on the support pads will prevent the heatsink from seating as tightly as it should against the core & the thermal transfer will be reduced. I know we're probably talking about microns here, but the bottom line is the grease should NOT be on those support pads.
In the meantime, if I see anyone walking around with grease on their forehead, I'll walk up & introduce myself. LMAO!

No, common logic says not to put grease on your forehead, so therefore you would not do it. Common logic also shows that those pads are only for support, just like suspension on a vehicle, tool, mattress, etc. So your analogy is incorrect. Baised on your hyper acting posts, you sound like a minor. If you can support some evidence as to why you cannot put grease on the pads, then I would believe that statement. Plus I do not know why you are trying to argue about putting grease on the pads, since I said I wiped it off of them.

Lighten up, dude, I was just having some fun with ya. Thanks for the compliment though, I haven't been mistaken for a minor since the early 70's!
As for my comments coming after your report of cleaning your pads...apparently your post was posted while I was in the process of writing my post. I have no control over that but it wouldn't have changed what I wrote anyway.
As for my analogy...common logic should tell you that two objects cannot be brought as tightly together if there's something in between them, as they could if there was nothing in between them...regardless if the item between them is grease & regardless if one of the objects is has rubber support pads on it. If you notice in my other post, I stated that "we're probably talking about microns". But to satisfy your ignorance, I will come up with a site or two that tells you NOT to apply grease to the rubber support pads.

To Grammar and jam, stop arguing, I don't think flaming is allowed. Grammar, you said the pads have been wiped off, and compound already applied to the CPU core, do you need help for anything else?

Yep, Jam is right.It has to be as tight as possible to the CPU. And putting stuff on the pads makes the pads taller, therefore possibly preventing the CPU from touching the heat sink.
Just make sure the whol of the centre square on the cpu is covered with the grease. If you miss even the corner, you will create a hot spot which is also bad news. Apply it evenly, and then make sure the heat sink is firmly against the centre square on the cpu.
You will then be fine to turn it on.

Another thing...thermal paste is conductive (electrically) so make sure you don't get it all over anywhere else...here's a link for installing heatsinks :¬)..(probably don't need it now but worth a read anyway)...

Just one other thing...you should have done your research BEFORE installation if you're new to this...not being funny about it..it just helps. You don't seem to know about applying thermal paste...I hope you did know as not to touch those pins on the processor..& at least earth yourself before attempting the upgrade...else the static from your body could damage the processor merely by touch if you touch those pins...if you did know..good on ya..if not..as I said...wise to research the job in hand first.

Thank you all, thanks to Jam and the others who have posted. I now have everything fixed. To the above poster, yes, I should have done research, but since I never heard anyone speak of applying grease, I thought you just put it on the CPU and it was complete. I also assumed that it would have came with instructions on where to apply the grease. That is why I came here to ask before I even plugged up the CPU, so I did double check and made sure everything was right :) I am sorry, this is the only site I can go to out of my 4 favs that doesn't have any flaming. I do not want to start a trend. It was jam's insults that made me counter. Sorry, and thanks

I did not deliberately insult...& I apologize if my comments were taken as such. I just attempted to use a little humor in my replies. If you noticed, I followed my forehead/grease comment with "seriously"...that in itself should tell you that the prior statement was NOT to be taken seriously. I'm glad to hear that you finally got things worked out though & I hope I was able to help, irregardless of my inappropriate behavior.
Now...there's another post in this thread claimimng that thermal compound is electrically conductive...would anyone like to tackle that issue before I get myself into more trouble? LOL!

jam - man don't apologize for that you didn't do or say anything wrong. The guy did something stupid and got called on it and then got defensive about it. He is the one that should apologize.

the well used/well known arctic silver is electrically conductive for one. Yes you will get yourself into trouble if you tackle this :¬)There are warnings on their website alone saying so...even a slight risk it seems of it interferring with processor/heatsing. As for every type of thermal compound being electrically conductive..ok that's a good question. Maybe the above post answers that :¬)

I have to stress though....this is not the case if you apply thermal paste in moderation to the four pads on the processor. :¬)

I am sure NASA have the answer. LMAO. They must have come across a substance that could be used, but awaiting the time to copyright it and tell us all about it, when they are short of a buck or two. LMAO

I am a chemical engineer for Dow Corning. We make the thermal pastes for NASA. They are generically similar to the paste that Radio Shack sells. There are special “vapor” issues that occur in a vacuum so the solvent mixes vary. Otherwise, camera lenses, windows etc would fog up. Under most conditions, this thermal paste does not conduct electricity.

Cool. My half uncle worked for NASA in the 70's. He is an engineer, a scientist and also stinking dirty rich. Owns a frickin massive boat moored on the Thames river at the end of his garden!
I am poor. But rich in spirit!

Or maybe they already have revealed any new grease on the NASA channel... Surprise word hasn't spread faster... Someone's gotta watch that channel!
Tony
