- We have recently received some 486/50 pcs. They're nice and
- fast machines. Since we were somewhat concerned about overheating,
- the clone vendor put heat sinks on the CPU. The heat sinks are
- really impressive ones: they are huge, fits over and covers the
- entire chip with an huge array of cooling fins.
-
- Being somewhat curious, we took off the sink and saw a small
- rectangular sticker that went from the middle of the chip to over
- the edge. It had some statement like "warranty void if removed".
-
- This seemed really strange for the following reasons:
-
- 1. Warranty labels on a chip? We've ordered many PCs over the
- years from this vendor and others. This is the first instance
- that we've ever seen of such a warning sticker. Is this
- being commonplace? Is it the clone vendor trying to lock in
- future business? (Sleaze? In the computer business? No way!)
-
- 2. We are wondering whether this would dilute or even worsen the
- cooling benefits of the heat sink since the sticker prevents
- contact of the sink with the chip over that part and allows
- an additional layer of air which could defeat the purpose of
- the heat sink. Further, depending on how much air space there
- is between the sink and the chip, the chip may be worse off
- because (much) hotter air would be trapped over the chip by the
- sink. Any thoughts on this?
-
- 3. Someone mentioned that there is a sort of gel/goop available on
- the market that one applies to the heat sink to allow a good
- contact between the sink and the chip thus facilitating cooling.
- Has anyone had any experience with this stuff?
-
- Thanks for any comments or suggestions.
