Discussion Overview

The discussion centers around the question of whether a Pentium 4 CPU chip can be cleaned with water and detergent without causing damage, specifically addressing the waterproof nature of the chip and the potential risks involved in the cleaning process.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that the chip itself is waterproof but warns about the risks of leaving corrosive or conductive residues from water or detergent on the pins.
  • Another participant mentions that PCBs are typically washed at the factory, implying that cleaning might not be as risky as suggested.
  • A different viewpoint recommends using aerosol contact cleaner and a toothbrush for cleaning, indicating a preference for methods that avoid water.
  • Another participant advises using isopropyl alcohol or rubbing alcohol for cleaning, suggesting it as a safer alternative to water.
  • One participant emphasizes the importance of careful scraping to remove thermal paste without damaging the chip.

Areas of Agreement / Disagreement

Participants express differing opinions on the safety of using water for cleaning the chip, with some asserting it is acceptable while others recommend alternative cleaning methods. The discussion remains unresolved regarding the best approach to cleaning the CPU without risk of damage.

Contextual Notes

Participants do not reach a consensus on the effectiveness or safety of various cleaning methods, and there are concerns about potential residues and physical damage during the cleaning process.

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.
 
Dear Experts,
Thank you so much for the advice and explanations.
You guys are great.
Cheers.
