I dont have thermal grease, what is a good alternative?

Years ago I used silver paint and it worked well.

You might experiment with alternatives, but why take the risk when thermal paste is cheap? –  Stephen Jennings May 6 '11 at 5:47
    
You're going to risk a $50-300+ part for want of $8 of thermal grease? –  jcollum Dec 13 '13 at 0:40
    
Stephen and Collum, ever consider availability? Maybe that person lives somewhere where thermal paste is not available in stores and they can’t order it online; not everywhere is the United States. Remember, the Internet is global. –  Synetech Dec 13 '13 at 1:33

Unless it's an emergency just wait until you have thermal paste. If it is an emergency:

Thermal paste mostly works due to the zinc oxide. The best TEMPORARY fix is to use diaper rash cream from a grocery store.

It's important to remember though that while both products are nearly identical, diaper rash cream has a lot of extra stuff including a higher water content so use just a tiny drop on the end of a toothpick and replace it with real thermal paste ASAP.

This thread seems to suggest some interesting options:

  • Cod Liver Oil
  • Silver Paint
  • Tin Foil
  • Liquid Metal

Take these suggestions with a pinch of salt. I'd just order more online.

"Pinch of salt" here being a figure of speech :-) –  Sirex May 6 '11 at 11:31

Don't forget JBweld, read an article back before 1ghz processors came out, they found JBweld did a better job than thermal paste, only one problem, it tends to be permanent. –  Moab May 6 '11 at 15:08

Actually, tin-foil was the first McGyver solution that popped into my head, but of course, it is essentially pointless because it is solid and thus leaves the air-pockets unaffected, so it is no different that not using it at all. Also, with a thermal conductivity of up to 1,462.5 times that of air, a pinch of salt actually would be practical, literally. –  Synetech Dec 13 '13 at 1:45
