applying thermal paste for the first time

post #1 of 18
Thread Starter 
Hi guys. I'm trying to apply the AS5 thermal paste for the first time. I got the surface cleaned from the old thermal and ready to apply the new one.

I know that I should put a dot of the paste in the center of the heat spreader, then put the heatsink on top of it, and eventually move it clockwise/counterclock wise to have the paste spreaded.

However, I'm using the 478 stock heatsink, and I'm not sure that when i'll put it back on the processor, I'll be able to move it at all. Isn't it fixed firmly?

What do you clean it with? And you shouldn't be able to move it at all

you can clean off the top of the processor with rubbing alcohol which works well as a cleaner. also makes it easier to apply to a clean surface.. dont do what the idiot did in my avatar

HS/FAns are designed to be removed from the processor.. for future upgrades/cleaning. ect.

I don't think you understood me correctly.

I already cleaned the surface with alcohol. My problem is when applying the thermal paste. I know I should put a dot-size of the material, and then in order to smear I can turn the heatsink clockwise/counterclockwise. But when I put the heatsink back it's firmly locked, so how can I move it in order to smear the paste?

Put a dot on it.
Seat heatsink.
Keep twisting heatsink for 1 minute or so.

okay heres the thing..
socket 478 processors "Dye" is in the center of the processor.
if you were to just put a rice sized application of thermal paste and the put the heatsink on you should be fine
also take into account that it takes like 100hours for the thermal paste to cure and start working at 100% potential

EDIT** you should not have to twist the HS/fan in anyway on 478 processors

thank you

what do you mean by "dye"?
and shouldn't I twist it at all?

gonX: that's the thing - I think it gets firmly locked after putting it on the processor.

1. it wont lock if you put the HS/fan on the processor (if you mean lock then he is refering to the CLIPS that the stock hs/fans use and they can be uasily unlocked )

2. the dye is what makes your processor hot. it is underneath the shiny silver top of your processor.. if you look at my avatar there is a black square in the middle of that processor. that is the dye of the processor

3. socket 478 processors has their dye in the center of the processor. you should not have to twist the HS/fan to spread the thermal paste anywhere because it is in the middle of the processor and when you put the hs/fan down it will smoosh the paste in the center which is where you will need it most.

Thanks guys.

I did what you told me, but I have to admit that after putting the heatsink down on the cpu, I couldn't move it much around - basically I could only tilt it. Is that enough(I'm not just referring to the 478, but generally - would that be enough?).

Does the fact I'm getting normal temps(42-45c idle, 60c full load - presscot cpu) mean that I did things right?

Yes, if your temps are normal you did an OK job. For future reference, alot of folks around the forum (including myself) have found that better results can be had by applying the AS5, and then using a credit card to smear it evenly over the IHS/CPU Die. You might consider doing it that way next time. When you put on the AS5 and rotate the HSF you are not covering the entire surface area of the IHS, which can lead to elevated temps because of bad/no contact.
