Alternative to thermal grease

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

Years ago I used silver paint and it worked well.

There are some interesting answers below. However, without documented proof that they work *and* are safe to use, I wouldnt try them unless you accept the risk of damaging your electronics. – Keltari – 2015-01-07T15:23:37.400

You might experiment with alternatives, but why take the risk when thermal paste is cheap?

3You're going to risk a $50-300+ part for want of $8 of thermal grease? – jcollum – 2013-12-13T00:40:18.523

2Stephen 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 – 2013-12-13T01:33:55.667

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.

I don't know if it's the best one, but it works well. – Pedro Werneck – 2015-03-06T15:00:22.337

Toothpaste (non grit) and pencil lead shavings work well together, I got a 10 degree Celsius decrease using this method.

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.

4"Pinch of salt" here being a figure of speech :-) – Sirex – 2011-05-06T11:31:11.030

1Don'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 – 2011-05-06T15:08:39.997

1Actually, 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 – 2013-12-13T01:45:11.377

On a recent assembly, my thermal paste was dried up so I ran without. Big No-No. I was pushing temps of 87 idle topping @ 106 before thermal overload and system shutdown.

I did some quick research and decided on 'Anti-Seize' as an alternative mainly because I had it on hand. I've been running for a week now on a 130 watt processor (as of July 29, 2015) with idle temps at 47 C & full load at 58 C.

Published Operating range is 5 - 68.6 C so I can live with those temps.

Thanks for your answer. But focus more on answering the question and leave out extraneous information like build parts and cost. – PatKilg – 2015-07-29T22:52:00.113
