160F (71C) is WAAAYYYYY too hot!
That setup is NOT correct and you may damage your system running it further.
Thermal compound will not rectify this.
You most likely have a defective installation.
There is usually (like always) a thin plastic covering over thermal pads that must be removed BEFORE use. If your system is running that hot, you either have not removed it, or the heatsink is not properly attached.
Shutdown. Take it apart again. Think to yourself how lucky you are it still works at all and make a choice. Examine the parts (cpu and heatsink). If you are 100% confident you know what the die should look like (shiny, almost silver with a faint green/blue tint) and the heatsink and thermal pad (pad is now probably history since they do not re-use well) try to clea both with a little nail varnish remover and lint free cloth and apply thermal compound per the <A HREF="http://www.articsilver.com" target="_new">http://www.articsilver.com</A> instructions (similar instructions whether it is ASII or radioshack) and have a go.
OR (and this is my advice) take it all to the dealer, ask them to assemble it properly and certify that the HS and cpu are all mounted correctly, carry it home, check all is still attached and then fire it up, forgetting about your narrow shave.
Seriously - if you do not install the HS properly on a 1.33Ghz Athlon it WILL die faster than you can get to the powerswitch....
Just another thought - you do have a fan on the heatsink and it is turning - right???
