Is Pentium 4 CPU chip waterproof ?

  • #1

Main Question or Discussion Point

Dear Gurus,

I have an old pentium chip covered with thermal paste that is kind of dried and difficult to remove. I intend to clean it with detergent and water.

Would it still work after it is cleaned and dried? That is , is it waterproof?

Thanks for taking time to read my question.

regards
Ramone

The chip itself is waterproof, the danger is leaving traces of corrosive or conductive salts from the water or detergent on any of the pins after you have dried it.

I would try and clean the thermal goo off with a straight hard plastic blade - don't use a knife you will scratch it.
Then polish the top smooth and clean on your jeans.

PCBs are typically washed at the factory after the components are soldered on. Personally, I wouldn't worry. I think the risk of damage from static electricity or bending a pin would worry me more.

You should be able to find aerosol "contact cleaner" at most places that sell electrical/electronic supplies. Most stuff will come off with a blast of the cleaner, but a cheap toothbrush (clean the bristles with the contact cleaner first) helps loosen the tougher deposits.

Use IPA (isopropyl alcohol) or rubbing alcohol and careful scraping as suggested above.
