Dielectric grease on CPU instead of thermal paste?

I called two computer repair shops to find some thermal paste for a CPU upgrade. Neither had any, but suggested that I use dielectric grease (found at an auto parts supplier) for the job. While applying it to the processor I found it to be very similar in color and consistency to neosporin ointment rather than a paste. I ran my PC and performed simple operations for about an hour with no problems. CPU temp. held strong at 38 degrees Celsius. Should I have any worries?

not really, its very similar stuff.

it may not perform quite as well as high end CPU TIM, but it should get the job done.

I would take it off asap, it has a tendency to liquify.

I certainly would not use it. Thermal characteristics will be suboptimal.

Most dielectric grease, IIRC can stand up to 300F.

Are there different types of dielectric grease? The stuff I used was transparent, very similar to vaseline in color and consistency.

Your local Radio Shack should have thermal paste. Dielectric grease is used to keep moisture out of auto bulb sockets and spark plug boots and not designed for thermal conductivity.

The MSDS specs on "permatex dialectic grease" says about half way down says
