CPU heatsink/thermal compound
i think its tme to renew this stuff
is it easier to buy a new hs/fan with pre applied thermal compound or use current hs/fan i had pre applied thermal compound on it and its now very rouch and a bit messy, temp is idle at 57 C on Socket A 2600+ not overclocked (previously, when compound was new and hs/fan was new 42 C idle, it is a stock amd cooler) which is far too hot so should i sand the bottom of the hs to get rid of the messy thermal compound and r apply some arctic silver? what about the compound still on the core of the CPU, can i cleanr that off, or should i leave? with all this in mind would i not be better off buying a new hs/fan with some more pre applied compound, hat with the arctic silver 5 costing and the cost of a hs/fan with pre applied compound it may be cheaper to buy a whole new hs/fan with pre applied compound whats the best route to take |

If you buy similar heatsink you'll get similar results (assuming same thermal interface method), so either buy a better heatsink than the original else there's no point to it. A different heatsink with 80-92mm x 25mm low-RPM fan would be the quietest alternative, a stock-speed Athlon XP2600 isn't producing so much heat that it can't be cooled near inaudibly with minimal effort, provided you use the right fan. Usually that means buying a fan separately, but IIRC Thermaltake's Silent Boost comes with a ribbed variant of a Panaflo L1A which is pretty quiet to begin with but might still be undervolted a bit. Since you already have the original heatsink you might first try cleaning it off, lightly lapping it, and applying (whatever happens to be handy, that you already have) heatsink grease. If the temps aren't low enough then consider purchasing additional supplies. If you don't have any higher-end thermal compound you might consider Arctic Alumina or Ceramique, it's close enough in performance, synthetic so it won't pump or dry out, and due to being non-capacitive it'll be more useful for other heatsinking like video card or motherboards, etc... Not to mention that it's less expensive and easier to clean up. |

Not to mention that it's less expensive and easier to clean up. by the way should i be using something like white spirit to clean the CPU? or is that a no no, with it being flamable? not sure what i should use to clean the core... any household items or am i gonna need a trip to homebase or somewhere for some specialized cleaning materials? |

Flammability is not a problem, but you dont' need anything highly volatile either. I usually use "Goo Gone", which is meant to get adhesive off of things, but other common petroleum-based solvents would work, even gasoline or WD-40. not sure what i should use to clean the core... any household items or am i gonna need a trip to homebase or somewhere for some specialized cleaning materials? Same thing, petroleum-based solvent. Read labels of cleaning /etc type products you already have, if it lists "petroleum solvent" in the label it'll probably do the job. If the thermal interface material is really thick and stubbon on the CPU it may help to saturate a rag or paper towel with solvent, put that against the top of the CPU and seal it in a plastic bag to soak for a few hours. It's not necessary but if you're not in a hurry it takes less effort that way. |
