Could anyone recommend a good quality thermal paste to use on a set of hair straighteners

I use Dow Corning 340 heat sink compound... Good stuff...

Alternatively, if you can, use an elastomeric heat sink sheet...

I should try that do you know what temperature it will handle

I always use the arctic range of products when I can afford it, and it warrants a good thermal conduction:

I've had heatsinks in high frequency H-bridges hit 200C under load, so its good to that - most heatsinks in class A amps I've uilt have tended to hover around the 80C or less mark. The datasheet at http://www.dowcorning.com/applications/s...ountry=GBR gives more info. Critical thing is the termal resistance, which at 0.16 ºC*cm2/W is pretty good (very good for the price) when you do the sums - Farnell sell it at about 7 quid a tube (ex VAT) - http://uk.farnell.com/dow-corning/226593...Ntt=101685. Its good stuff - use it for all my amps - lasts for ever.

That's the stuff folk use for CPU heatsinks - very pricey. Interestingly, I've not been able to find a data sheet for it so its thermal resistance is unknown and it cannot therefore be compared with (much cheaper!) alternatives - they quote "up to a 5C temperature drop" - completely meaningless. Whilst supposedly not conductive (can't really tell as no data sheet!) they do state it is capacitive (but not by how much). As its really designed for low voltage (CPU) heatsinks and no data sheet is available, I would certainly not trust it with anything HV.

Looks good though !
