Should I Use the Strip on the Bottom of The Heat Sink in Conjunction with Thermal Greese on Processor?

Hi Everyone:

        I hate to bother everyone with so many questions, but, I am still learning as I go.  In any case, I am wondering if the adhesive strip on the bottom of the heat sink should be used in conjunction with some thermal greese on the processor?  I noticed when the heat sink was removed, there was thermal greese on the core of the processor, so, I assume that both have to be used.  Additionally, it looks like the protective film has been removed too and reattached.  Under these conditions, I think it would be wiser to go ahead and put thermal greese on the processor, but, only after carefully removing the old buildup.

         Does everyone else concur with this?

        George

You do need to clean off all previous thermal greese as adding more will just start building up and pushing the greese twards sections of the processor that could get damaged by it and in turn fry your chip. I would not recomend using the preapplied thermal patch on the bottom of the heatsink with thermal greese for the same reasons stated above. Make sure you do not put too much thermal greese on the cpu as the same as above could happen, the greese / paste is only there to fill in the micro grooves that cannot be completely removed and there for cause hot spots on the casting of the cpu which could lead to cracking and eventually cpu failure.

Hope this helps.

Hi There:

         Should I leave the protective strip on the bottom of the heat sink, remove the old thermal greese, and apply new thermal greese?  Incidentally, there is some pre-existing thermal greese on the outside of the processor.  Should I leave it alone or should I attempt to remove it carefully using a q-tip and some alchohol?

          Thanks

When you say protective strip are you talking about a plastic protective strip or a strip of thermal compound, if it's plastice remove it if it is just a patch of thermal compound then it is your choice if you want to use thermal grease or the compound on the heat sink. As for the buildup on the processor it would be best to remove it using Akasa Thermal Interface Cleaner, it is about $5 but will not damage the cpu, using alcohol could be done but there is a chance that it could damage something, I prefere being safe and spend $5 which will let me clean 100's of cpu's of buildup. It's well worth it.

If you are using the arctic silver, george, get rid of everything else, the strip on the heat sink, the old grease on the CPU -- everything, and apply a thin layer of the arctic silver to the CPU top.  Also make sure none spills over off the sides of the cpu far enough to make contact between the tiny resistor terminals surrounding the CPU.  In rare cases (rare) this can cause a CPU to not work.  But with enough arctic silver on the CPU (a 0.5 mm coating) you can wipe the heatsink clean of everything.

You don't use both; you use one or the other.  The protective film, if any, must be removed.  If there is any doubt as to what to do, or if the heatsink has been previously used, it may be best to remove all of everything from both the heatsink and CPU and start over, using a good quality thermal compound.  You don't use much, just about the equivalent of 2 grains of rice.
